FIELD OF THE INVENTION

Disclosed herein are all natural or substantially natural deodorant and antiperspirant compositions comprising 1,3-propanediol wherein the 1,3-propanediol in said all natural or substantially natural deodorant or antiperspirant composition has a bio-based carbon content of about 1% to 100%. In addition, it is preferred that the 1,3-propanediol be biologically-derived, and wherein upon biodegradation, the biologically-derived 1,3-propanediol contributes no anthropogenic CO2 emissions to the atmosphere.

BACKGROUND OF THE INVENTION

Perspiration produced in the apocrine sweat glands of the armpits (axilla) contains proteins and fatty acids. While initially odorless, this sweat becomes malodorous when bacteria on the skin and hair metabolize the proteins and fatty acids. The problem of odoriferous sweat breakdown products is generally addressed in two ways by personal care products—antiperspirancy and deodorancy.

Antiperspirancy commonly is achieved by topically applying a composition containing a metal salt, such as an astringent aluminum or aluminum/zirconium salt. An influx of aluminum ions into secretory coil cells of human sweat glands are accompanied by an influx of water, causing the sweat gland cells to swell, squeezing the sweat ducts closed, and stopping perspiration.

Deodorants function in several ways. Some mask the odor from bacterial breakdown products; others react with the bacterial and/or their byproducts that cause odor. Still others achieve deodorancy by inhibiting bacterial growth.

Most deodorant products currently on the market contain synthetic carbon based glycol. Indeed even an estimated 50% of deodorant products claimed to be natural still contain synthetic non-bio based glycol and may often contain synthetic antibacterial agents to help kill the bacteria that cause odor. Vegetable glycerin based deodorant formulations are on the rise and now represent approximately 50% of the “natural” deodorant stick category. It is a known fact, however, that vegetable glycerin formulas present several key challenges including stability and stickiness. In order to stabilize glycerin formulas, often at least one, and more often several, man-made, synthetic chemical ingredient are used. Stickiness is a key detergent for consumers, and one of the main reasons this type of product hasn't penetrated the marketplace.

Consumers of deodorants and antiperspirants consider many factors in selecting products for use. Recently certain factors have been a focus of and have driven scientific study and product development. These driving factors include, product safety, environmental impact, the extent to which the components are natural, and the aesthetic quality of the overall product. Therefore, manufacturers have to be concerned with the environmental impact of their products. In fact, the effort towards environmental impact awareness is a universal concern, recognized by government agencies. The Kyoto Protocol amendment to the United Nations Framework Convention on Climate Change (UNFCCC) currently signed by 156 nations is one example of a global effort to favor safer environmental manufacturing over cost and efficiency. When applied to deodorants and antiperspirants, consumers are increasingly selective about the origins of the products they purchase. The 2004 Co-operative Bank's annual Ethical Consumerism Report (www.co-operativebank.co.uk) disclosed a 30.3% increase in consumer spending on ethical retail products (a general classification for environmental safe, organic and fair trade goods) between 2003 and 2004 while total consumer spending during the same period rose only 3.7%.

Glycols such as ethylene glycol, propylene glycol, 1,3-butylene glycol, and 2-methyl-1,3-propanediol are biodegradable compounds useful in compositions ranging from cosmetics and personal care formulations to detergents to heat transfer compositions. While biodegradability is an important factor in protecting the environment, biodegradation of glycols derived from fossil-based sources has the unavoidable consequence of releasing previously fixed CO2 into the atmosphere. Thus, while glycols in general are advantageous for their biodegradability, the resulting global warming potential of fossil-based glycols during biodegradation is significant.

Carbon dioxide is singled out as the largest component of the collection of greenhouse gases in the atmosphere. The level of atmospheric carbon dioxide has increased 50% in the last two hundred years. Recent reports indicate that the current level of atmospheric carbon dioxide is higher than the peak level in the late Pleistocene, the epoch before modern humans (Siegenthaler, U. et al. Stable Carbon Cycle-Climate Relationship During the Late Pleistocene, Science, Vol. 310, no. 5752 (Nov. 25, 2005), pp. 1313-1317). Therefore, any further addition of carbon dioxide to the atmosphere is thought to further shift the effect of greenhouse gases from stabilization of global temperatures to that of heating. Consumers and environmental protection groups alike have identified industrial release of carbon into the atmosphere as the source of carbon causing the greenhouse effect.

Greenhouse gas emission can occur at any point during the lifetime of a product. Consumers and environmental groups consider the full lifespan of a product when evaluating a product's environmental impact. Consumers look for products that do not contribute new carbon to the atmosphere considering the environmental impact of production, use and degradation. Only organic products composed of carbon molecules from plant sugars and starches and ultimately atmospheric carbon are considered to not further contribute to the greenhouse effect.

In addition to adding carbon dioxide to the atmosphere, current methods of industrial production of glycols produce contaminants and waste products that include among them sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, oxalic acid tartaric acid, acetic acids, Alkali metals, alkaline earth metals, transitional metals and heavy metals, including Iron, cobalt, nickel, copper, silver, molybdenum, tungsten, vanadium, chromium, rhodium, palladium, osmium, iridium, rubidium, and platinum (U.S. Pat. Nos. 2,434,110, 5,034,134, 5,334,778, and 5,10,036).

Also of concern to consumers, especially consumers of deodorant and antiperspirant products, is an individual's reaction to such a product. The rate of development of hypersensitivity has markedly increased in the US in the last two decades. Many of these reactions are attributed to trace amount of substances. Other reactions are of idiopathic origin. Consumers seek products that are composed of ingredients of a more purified source and/or of all natural composition.

DETAILED DESCRIPTION OF THE INVENTION

Applicants specifically incorporate the entire content of all cited references in this disclosure. Further, when an amount, concentration, or other value or parameter is given as either a range, preferred range, or a list of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. Where a range of numerical values is recited herein, unless otherwise stated, the range is intended to include the endpoints thereof, and all integers and fractions within the range. It is not intended that the scope of the invention be limited to the specific values recited when defining a range.

Applicants' invention relates to all natural and/or substantially natural deodorant and antiperspirant compositions or systems comprising at least one glycol component, which has at least 1% bio-based carbon content. The preferred glycol in the invention is 1,3 propanediol. It is further preferred that the deodorant compositions be all natural or substantially natural. The term “all natural” means that the compositions of the invention are free of ethoxylates and/or other petrochemically reacted or derived substances.

The term “substantially natural” means that the compositions of the invention are substantially free of ethoxylates and/or other petrochemical derivatives. It is preferred that substantially natural compositions are made up of about 70% to 100% ingredients of natural origin, and any percentage there between.

For the purposes of the present application, “of natural origin” means that the material is a portion of a plant, a fungus, a mineral or animal, or an extract or specific isolate thereof. The vehicle used to obtain the extract or isolate may be selected from any suitable material known to persons of skill in the art. Preferably, the extraction vehicle is not a petroleum product. The natural deodorant system of the claimed invention is primarily free of, preferably substantially free of, more preferably essentially free of, and most preferably completely free of ethoxylates or other petrochemical derivatives. A preferred embodiment of the present invention consists of 1, 3 propanediol in combination with one or more naturally derived stabilizers including either hydrocolloids, and/or natural emulsifiers such as for example monoglycerides, polyglycerol, sugar or sorbitan esters.

While it is a general practice in the art to distinguish between deodorant compositions and antiperspirant compositions, in order to simplify this application, it is intended for purposes of this invention, that the terms “deodorant” and “antiperspirant”, while used separately at times, will be considered synonymous and may be used interchangeably throughout the application to describe the compositions of the invention.

Compositions disclosed herein comprise 1,3-propanediol, having at least 1% bio-based carbon content, as greater as up to 100% of the glycol component of the composition. In one embodiment, the 1,3-propanediol comprises substantially all of the glycol component of the composition of the invention. In another embodiment, the 1,3-propanediol comprises all of the glycol component of the composition.

1,3-Propanediol

The terms “bioPDO”, “biologically-derived, biodegradable 1,3-propanediol”, “biologically derived 1,3-propanediol”, “renewably-based 1,3-propanediol”, “renewably-based, biodegradable 1,3-propanediol,” “biosourced, and “biologically-produced 1,3-propanediol” and similar terms as used here in refer to 1,3-propanediol derived from microorganism metabolism of plant-derived sugars composed of carbon of atmospheric origin, and not composed of fossil-fuel carbon.

CO2 Emission Profile

Applicants' invention relates to all natural or substantially natural deodorant and antiperspirant compositions comprising renewably-based, biodegradable 1,3-propanediol, in which said renewably-based, biodegradable 1,3-propanediol has an anthropogenic CO2 emission profile of zero (0). An “anthropogenic emission profile” means anthropogenic CO2 emissions that are contributed to the atmosphere upon biodegradation of a compound or composition.

“Biodegradable” or “Biodegradability” means the capacity of a compound to be broken down by living organisms to simple, stable compounds such as carbon dioxide and water.

Whereas photosynthesis is the process of creating growing matter through the conversion of carbon dioxide (CO2) and water (H2O) into plant material through the action of the sun, biodegradation is the process of converting organic material back into CO2 and H2O through the activity of living organisms.

There are many published test methods for measuring the biodegradability of organic chemicals such as glycols. One internationally recognized method is ASTM E1720-01, Standard Test Method for Determining Ready, Ultimate Biodegradability of Organic Chemicals in a Sealed Vessel CO2 Production Test.

Chemicals that demonstrate 60% biodegradation or better in this test method will biodegrade in most aerobic environments and are classified as ready biodegradable. All of the glycols referred to in this document meet this criteria.

Calculations setting forth the finding that the 1,3-propanediol of the present invention provides no anthropogenic COs emissions upon biodegradation is set forth below. A table in support of these calculations is provided in FIG. 3.

When one molecule of 1,3-propanediol degrades, three molecules of CO2 are released into the atmosphere. Because all of these molecules of CO2 released during degradation from “fermentatively-derived” 1,3-propanediol have an atmospheric origin, the net release of CO2 to the atmosphere is thus zero. Comparatively, because a fossil fuel-derived propylene glycol and fossil-derived 1,3-propanediol contains three carbon atoms which originate from a fixed carbon source (i.e., the fossil fuel), degradation of one molecule of fossil fuel-derived propylene glycol or 1,3-propanediol results in a net release of three molecules of CO2 into the atmosphere. Similarly, because fossil fuel-derived ethylene glycol contains two carbon atoms, which originate from a fixed carbon source, degradation of one molecule of fossil fuel-derived ethylene glycol results in a net release of two molecules of CO2 into the atmosphere.

In order to quantify the CO2 released for one kilogram of each ethylene glycol, propylene glycol, chemical 1,3-propanediol and “fermentatively-derived” 1,3 propanediol (Bio-PDO™), the product weight (1 kg) is divided by its molecular weight. For each carbon atom present in the molecule, one molecule of CO2 is released. The molecules of CO2 are multiplied by the molecular weight of CO2 (44 kg/kmole) to quantify the impact of CO2 release (kg) per one unit (kg) of product.

Fossil-Fuel Based Carbon Feedstock Release
1 kg of fossil fuel derived ethylene glycol*(1 kmol EG/62.068 kg)*(2 kmol CO2/1 kmol EG)*(44 kg CO2/kmol CO2)=1.4 kg CO2
1 kg of fossil fuel derived propylene glycol*(1 kmol PG/76.094 kg)*(3 kmol CO2/1 kmol PG)*(44 kg CO2/kmol CO2)=1.7 kg CO2
1 kg of fossil fuel derived 1,3-propanediol*(1 kmol chem-PDO/76.094 kg)*(3 kmol CO2/1 kmol chem-PDO)*(44 kg CO2/kmol CO2)=1.7 kg CO2
Bio-Based Carbon Feedstock Balance

Capture:
1 kg of Bio-PDO™*(1 kmol Bio-PDO™/76.094 kg)*(−3 kmol CO2/1 kmol Bio-PDO™)*(44 kg CO2/kmol CO2)=−1.7 kg CO2

Release:
1 kg of Bio-PDO™*(1 kmol Bio-PDO™/76.094 kg)*(3 kmol CO2/1 kmol Bio-PDO™)*(44 kg CO2/kmol CO2)=1.7 kg CO2

Net:
−1.7 kg+1.7 kg=0 kg

This Bio-based Carbon Feedstock Balance result demonstrates that there are no anthropogenic CO2 emissions from the biodegradation of the renewably sourced Bio-PDO. The term “anthropogenic” means man-made or fossil-derived.

Bio-Based Carbon

“Carbon of atmospheric origin” as used herein refers to carbon atoms from carbon dioxide molecules that have recently, in the last few decades, been free in the earth's atmosphere. Such carbons in mass are identifiable by the present of particular radioisotopes as described herein. “Green carbon”, “atmospheric carbon”, “environmentally friendly carbon”, “life-cycle carbon”, “non-fossil fuel based carbon”, “non-petroleum based carbon”, “carbon of atmospheric origin”, and “biobased carbon” are used synonymously herein.

“Carbon of fossil origin” as used herein refers to carbon of petrochemical origin. Such carbon has not been exposed to UV rays as atmospheric carbon has, therefore masses of carbon of fossil origin has few radioisotopes in their population. Carbon of fossil origin is identifiable by means described herein. “Fossil fuel carbon”, “fossil carbon”, “polluting carbon”, “petrochemical carbon”, “petro-carbon” and carbon of fossil origin are used synonymously herein.

The abbreviation “IRMS” refers to measurements of CO2 by high precision stable isotope ratio mass spectrometry.

The term “carbon substrate” means any carbon source capable of being metabolized by a microorganism wherein the substrate contains at least one carbon atom.

“Renewably-based” denotes that the carbon content of the 1,3-propanediol is from a “new carbon” source as measured by ASTM test method D 6866-05 Determining the Biobased Content of Natural Range Materials Using Radiocarbon and Isotope Ratio Mass Spectrometry Analysis, incorporated herein by reference. This test method measures the C-14/C-12 isotope ratio in a sample and compares it to the C-14/C-12 isotope ratio in a standard 100% biobased material to give percent biobased content of the sample. “Biobased materials” are organic materials in which the carbon comes from recently (on a human time scale) fixated CO2 present in the atmosphere using sunlight energy (photosynthesis). On land, this CO2 is captured or fixated by plant life (e.g., agricultural crops or forestry materials). In the oceans, the CO2 is captured or fixated by photosynthesizing bacteria or phytoplankton. A biobased material has a C-14/C-12 isotope ratio in range of from 1:0 to greater than 0:1. Contrarily, a fossil-based material, has a C-14/C-12 isotope ratio of 0:1.

A small amount of the carbon dioxide in the atmosphere is radioactive. This 14C carbon dioxide is created when nitrogen is struck by an ultra-violet light produced neutron, causing the nitrogen to lose a proton and form carbon of molecular weight 14 which is immediately oxidized in carbon dioxide. This radioactive isotope represents a small but measurable fraction of atmospheric carbon. Atmospheric carbon dioxide is cycled by green plants to make organic molecules during the process known as photosynthesis. The cycle is completed when the green plants or other forms of life metabolize the organic molecules producing carbon dioxide which is released back to the atmosphere. Virtually all forms of life on Earth depend on this green plant production of organic molecule to produce the chemical energy that facilitates growth and reproduction. Therefore, the 14C that exists in the atmosphere becomes part of all life forms, and their biological products. These renewably based organic molecules that biodegrade to CO2 do not contribute to global warming as there is no net increase of carbon emitted to the atmosphere. In contrast, fossil fuel based carbon does not have the signature radiocarbon ratio of atmospheric carbon dioxide.

Atmospheric origin and fixed carbon source as used herein are relative terms in that the time period of when CO2 is of atmospheric or fixed origin relates to the life cycle of the 1,3-propanediol. Thus, while it is quite possible that, at one time, carbon from a fossil fuel was found in the atmosphere (and, as a corollary, that atmospheric CO2 may one day be incorporated into a fixed carbon source), for purposes herein carbon is considered to be from a fixed carbon source until it is released into the atmosphere by degradation.

Assessment of the renewably based carbon in a material can be performed through standard test methods. Using radiocarbon and isotope ratio mass spectrometry analysis, the biobased content of materials can be determined. ASTM International, formally known as the American Society for Testing and Materials, has established a standard method for assessing the biobased content of materials. The ASTM method is designated ASTM-D6866.

The application of ASTM-D6866 to derive a “biobased content” is built on the same concepts as radiocarbon dating, but without use of the age equations. The analysis is performed by deriving a ratio of the amount of radiocarbon (14C) in an unknown sample to that of a modem reference standard. The ratio is reported as a percentage with the units “pMC” (percent modern carbon). If the material being analyzed is a mixture of present day radiocarbon and fossil carbon (containing no radiocarbon), then the pMC value obtained correlates directly to the amount of Biomass material present in the sample.

The modern reference standard used in radiocarbon dating is a NIST (National Institute of Standards and Technology) standard with a known radiocarbon content equivalent approximately to the year AD 1950. AD 1950 was chosen since it represented a time prior to thermo-nuclear weapons testing which introduced large amounts of excess radiocarbon into the atmosphere with each explosion (termed “bomb carbon”). The AD 1950 reference represents 100 pMC.

“Bomb carbon” in the atmosphere reached almost twice normal levels in 1963 at the peak of testing and prior to the treaty halting the testing. Its distribution within the atmosphere has been approximated since its appearance, showing values that are greater than 100 pMC for plants and animals living since AD 1950. It's gradually decreased over time with today's value being near 107.5 pMC. This means that a fresh biomass material such as corn could give a radiocarbon signature near 107.5 pMC.

Combining fossil carbon with present day carbon into a material will result in a dilution of the present day pMC content. By presuming 107.5 pMC represents present day biomass materials and 0 pMC represents petroleum derivatives, the measured pMC value for that material will reflect the proportions of the two component types. A material derived 100% from present day soybeans would give a radiocarbon signature near 107.5 pMC. If that material was diluted with 50% petroleum derivatives, it would give a radiocarbon signature near 54 pMC.

A biomass content result is derived by assigning 100% equal to 107.5 pMC and 0% equal to 0 pMC. In this regard, a sample measuring 99 pMC will give an equivalent biobased content result of 93%.

A sample of “fermentatively-derived” 1,3-propanediol was submitted by DuPont to Iowa State University for biobased content analysis using ASTM method D 6866-05. The results received from Iowa State University demonstrated that the above sample was 100% bio-based content (ref: Norton, Glenn. Results of Radiocarbon Analyses on samples from DuPont Bio-Based Materials—reported Jul. 8, 2005).

Assessment of the materials described herein were done in accordance with ASTM-D6866. The mean values quoted in this report encompasses an absolute range of 6% (plus and minus 3% on either side of the biobased content value) to account for variations in end-component radiocarbon signatures. It is presumed that all materials are present day or fossil in origin and that the desired result is the amount of biobased component “present” in the material, not the amount of biobased material “used” in the manufacturing process.

There-may be certain instances wherein an all natural or substantially natural deodorant and antiperspirant composition of the invention may comprise a combination of a biologically-derived 1,3-propanediol and one or more non biologically-derived glycol components, such as, for example, chemically synthesized 1,3-propanediol. In such occasions, it may be difficult, if not impossible to determine which percentage of the glycol composition is biologically-derived, other than by calculating the bio-based carbon content of the glycol component. In this regard, in the all natural or substantially natural deodorant and antiperspirant compositions of the invention, the glycol component, and in particular, the 1,3-propanediol, can comprise at least about 1% bio-based carbon content up to 100% bio-based carbon content, and any percentage therebetween.

Purity

“Substantially purified,” as used by applicants to describe the biologically-produced 1,3-propanediol produced by the process of the invention, denotes a composition comprising 1,3-propanediol having at least one of the following characteristics: 1) an ultraviolet absorption at 220 nm of less than about 0.200 and at 250 nm of less than about 0.075 and at 275 nm of less than about 0.075; or 2) a composition having L*a*b* “b*” color value of less than about 0.15 and an absorbance at 270 nm of less than about 0.075; or 3) a peroxide composition of less than about 10 ppm; or 4) a concentration of total organic impurities of less than about 400 ppm.

A “b*” value is the spectrophotometrically determined “Yellow Blue measurement as defined by the CIE L*a*b* measurement ASTM D6290.

The abbreviation “AMS” refers to accelerator mass spectrometry.

By the acronym “NMR” is meant nuclear magnetic resonance.

By the terms “color” and “color bodies” is meant the existence of visible color that can be quantified using a spectrocolorimeter in the range of visible light, using wavelengths of approximately 400-800 nm, and by comparison with pure water. Reaction conditions can have an important effect on the nature of color production. Examples of relevant conditions include the temperatures used, the catalyst and amount of catalyst. While not wishing to be bound by theory, we believe color precursors include trace amounts of impurities comprising olefinic bonds, acetals and other carbonyl compounds, peroxides, etc. At least some of these impurities may be detected by such methods as UV spectroscopy, or peroxide titration.

“Color index” refers to an analytic measure of the electromagnetic radiation-absorbing properties of a substance or compound.

Biologically-derived 1,3-propanediol useful in all natural or substantially natural deodorant and antiperspirant compositions disclosed herein has at least one of the following characteristics: 1) an ultraviolet absorption at 220 nm of less than about 0.200 and at 250 nm of less than about 0.075 and at 275 nm of less than about 0.075; or 2) a composition having L*a*b* “b*” color value of less than about 0.15 and an absorbance at 270 nm of less than about 0.075; or 3) a peroxide composition of less than about 10 ppm; or 4) a concentration of total organic impurities of less than about 400 ppm. A “b*” value is the spectrophotometrically determined Yellow Blue measurement as defined by the CIE L*a*b* measurement ASTM D6290.

The level of 1,3-propanediol purity can be characterized in a number of different ways. For example, measuring the remaining levels of contaminating organic impurities is one useful measure. Biologically-derived 1,3-propanediol can have a purity level of less than about 400 ppm total organic contaminants; preferably less than about 300 ppm; and most preferably less than about 150 ppm. The term ppm total organic purity refers to parts per million levels of carbon-containing compounds (other than 1,3-propanediol) as measured by gas chromatography.

Biologically-derived 1,3-propanediol can also be characterized using a number of other parameters, such as ultraviolet light absorbance at varying wavelengths. The wavelengths 220 nm, 240 nm and 270 nm have been found to be useful in determining purity levels of the composition. Biologically-derived 1,3-propanediol can have a purity level wherein the UV absorption at 220 nm is less than about 0.200 and at 240 nm is less than about 0.075 and at 270 nm is less than about 0.075.

Biologically-derived 1,3-propanediol can have a b* color value (CIE L*a*b*) of less than about 0.15.

The purity of biologically-derived 1,3-propanediol compositions can also be assessed in a meaningful way by measuring levels of peroxide. Biologically-derived 1,3-propanediol can have a concentration of peroxide of less than about 10 ppm.

It is believed that the aforementioned purity level parameters for biologically-derived and purified 1,3-propanediol (using methods similar or comparable to those disclosed in U.S. Patent Application No. 2005/0069997) distinguishes such compositions from 1,3-propanediol compositions prepared from chemically purified 1,3-propanediol derived from petroleum sources, as per the prior art.

Fermentation

“Biologically produced” means organic compounds produced by one or more species or strains of living organisms, including particularly strains of bacteria, yeast, fungus and other microbes. “Bio-produced” and biologically produced are used synonymously herein. Such organic compounds are composed of carbon from atmospheric carbon dioxide converted to sugars and starches by green plants.

“Biologically-based” means that the organic compound is synthesized from biologically produced organic components. It is further contemplated that the synthesis process disclosed herein is capable of effectively synthesizing other monoesters and diesters from bio-produced alcohols other than 1,3-propanediol; particularly including ethylene glycol, diethylene glycol, triethylene glycol, 1,2-propylene glycol, dipropylene diol, tripropylene diol, 2-methyl 1,3-propanediol, neopentyl glycol and bisphenol A. “Bio-based”, and “bio-sourced”; “biologically derived”; and “bio-derived” are used synonymously herein.

“Fermentation” as used refers to the process of metabolizing simple sugars into other organic compounds. As used herein fermentation specifically refers to the metabolism of plant derived sugars, such sugar are composed of carbon of atmospheric origin.

Biologically-derived 1,3-propanediol can be obtained based upon use of the fermentation broth (“fermentatively-derived”) generated by a genetically-engineered Escherichia coli (E. coli) previously disclosed in, for example, U.S. Pat. No. 5,686,276. However, other single organisms, or combinations of organisms, may be used to biologically produce 1,3-propanediol, using organisms that have been genetically-engineered according to methods known in the art. “Fermentation” refers to a system that catalyzes a reaction between substrate(s) and other nutrients to product(s) through use of a biocatalyst. The biocatalysts can be a whole organism, an isolated enzyme, or any combination or component thereof that is enzymatically active. Fermentation systems useful for producing and purifying biologically-derived 1,3-propanediol are disclosed in, for example, Published U.S. Patent Application No. 2005/0069997 incorporated herein by reference.

The biologically derived 1,3-propanediol (Bio-PDO) for use in the current invention, produced by the process described herein, contains carbon from the atmosphere incorporated by plants, which compose the feedstock for the production of Bio-PDO™. In this way, the Bio-PDO™ used in the compositions of the invention contains only renewable carbon, and not fossil fuel based, or petroleum based carbon. Therefore the compositions of the invention have less impact on the environment as the propanediol used in the compositions does not deplete diminishing fossil fuels and, upon degradation releases carbon back to the atmosphere for use by plants once again. Thus, the present invention can be characterized as more natural and having less environmental impact than similar compositions comprising petroleum based glycols.

Moreover, as the purity of the Bio-PDO utilized in the compositions of the invention is higher than chemically synthesized 1,3-propanediol and other glycols, risk of introducing impurities that may cause irritation is reduced by its use over commonly used glycols, such as propylene glycol.

This 1,3-propanediol of the invention can be isolated from the fermentation broth and is incorporated into all natural or substantially natural deodorant and antiperspirant compositions of the invention, by processes as are known to those of ordinary skill in the applicable art.

Renewably-Based, Biodegradable 1,3-propanediol-Containing Compositions

As mentioned above, renewably-based, biodegradable 1,3-propanediol can be incorporated into all natural and substantially natural deodorant formulations as a glycol component. For example, renewably-based, biodegradable 1,3-propanediol can be part of or the sole glycol component of such all natural deodorant and antiperspirant compositions.

It is contemplated herein that other renewably-based or biologically-derived glycols, such as ethylene glycol, diethylene glycol, triethylene glycol, 1,2 propylene glycol, dipropylene glycol, tripropylene glycol, neopentyl glycol and bisphenol A, among others, can be used in the deodorant compositions of the present invention.

Deodorant compositions of the invention can contain up to about 99.9% by weight of the glycol component of the invention based on the weight of the total composition.

The invention is a directed to natural system for topical and systemic delivery of one or more natural active ingredients. For purposes of the present invention a “natural” ingredient shall mean an ingredient derived primarily from plant, animal or mineral that is essentially free of petroleum derived and petroleum modified/reacted substances.

In general, such natural ingredients include extracts, modified derivates or isolates derived from any portion of a plant, including, without limitation, flowers, leaves, stems, berries, rinds, fruits, pulps, resins, seeds, barks, roots, tubers, rhizomes, etc. of plants, or mineral or animal, that preferably provide deodorant activity and that are further primarily free of synthetic preservative ingredients such as triclosan, quaternary ammonium compounds, and ethoxylates. For purposes of the present invention “deodorant activity” as used in connection with a preservative ingredient shall mean capable of killing or hindering the growth of microorganisms that generate malodor or the use of enzymatic technology that alters the process so as to eliminate malodor.

In for purposes of the present invention, the term “primarily free of” in connection with a synthetic deodorant ingredient shall mean that the ingredient is used at concentration that does not provide any significant amount of bacteriostatic activity (i.e., inhibition of microbial growth). Bacteriostatic action is considered “significant” if an 80% or greater reduction in the growth of an inoculum of a relevant micro-organism is observed, relative to a control medium, without an anti-microbial agent, over a period of 16 to 24 hours at 37.degree. C. For deodorant products, since the substrate to be treated is human skin, a relevant micro-organism is Staphylococcus epidermidis. Methods for determining whether a synthetic ingredient has a significant amount of bacteriostatic activity are described by Balows et al., “Manual of Clinical Microbiology” (5th Edition, American Society for Microbiology, Washington D.C., 1991) and in U.S. Pat. No. 6,793,914, Col. 9, lines 1-15, the disclosure of which is hereby incorporated by reference.

For example, where triclosan is intended to provide a significant preservative or bacteriostatic activity in deodorant products (those not of the present invention), it is typically used at a concentrations of at least about 0.3% by weight. Accordingly, a person of ordinary skill in the art would understand that a deodorant composition primarily free of triclosan would contain triclosan in concentrations of less than 0.3%. Methyl paraben is representative of a phenolic compound commonly used in personal care products to provide preservative or bacteriostatic activity. To produce a significant amount of antimicrobial activity, methyl paraben is typically used at concentrations of at least about 0.1% by weight. A person of ordinary skill in the art would understand that a deodorant composition primarily free of methyl paraben would contain such compound at concentrations of less than 0.1%. A person of ordinary skill in the art would understand a deodorant composition primarily free of other phenolic compounds in a similar manner, i.e., providing no more deodorant activity than 0.1% of methyl paraben. Primarily free of synthetically derived quaternary ammonium compounds and ethoxylates would be understood in a manner similar to those illustrated above for triclosan and methyl paraben.

In a first general embodiment, the natural topical delivery system of the invention preferably comprises renewably-based, biodegradable 1,3 propanediol, and a natural emulsifier (preferably of plant origin), and if desired or necessary, water and/or one or more natural deodorant ingredients, including natural actives and structurants, in a system that is completely or substantially free of ethoxylates or other petrochemically derived or reacted substances. In an alternative general embodiment, the natural topical delivery system of the invention preferably comprises renewably-based, biodegradable 1,3 propanediol, and a natural active, and if desired, water and/or one or more natural deodorant ingredients, including natural emulsifiers and structurants, in a system that is completely or substantially free of ethoxylates or other petrochemically derived or reacted substances. In a third alternative general embodiment, the natural topical delivery system of the invention preferably comprises renewably-based, biodegradable 1,3 propanediol, water and a fragrance, and if desired or needed, water and/or one or more natural deodorant ingredients, including natural actives and emulsifiers, in a system that is completely or substantially free of ethoxylates or other petrochemically derived or reacted substances. In a fourth alternate general embodiment the natural topical delivery system of the invention preferably comprises renewably-based, biodegradable 1,3 propanediol, water and a fragrance, and if desired or needed, water and/or one or more natural deodorant ingredients, including natural actives and emulsifiers, in a system that is completely or substantially free of ethoxylates or other petrochemically derived or reacted substances.

The delivery system can take the form of any effective method for applying a deodorant, such as a spray, roll-on, flowable gel, cream, lotion, or solid stick. Varying viscosities can be achieved by combining the renewably-based, biodegradable 1,3 propanediol, water, colloids and/or natural emulsifiers in appropriate weight/weight ratios, such as, for example: spray or roll-on—renewably-based, biodegradable 1,3 propanediol from about 3% to about 80%, water from about 2% to about 90%, natural stabilizer from about 0.05% to about 5%; flowable gel—renewably-based, biodegradable 1,3 propanediol from about 2% to about 70%, water from about 25% to about 98%, natural stabilizer from about 0.1% to about 5%; cream—renewably-based, biodegradable 1,3 propanediol from about 1% to about 55%, water from about 3% to about 90%, natural stabilizer from about 0.1% to about 6%; lotion—renewably-based, biodegradable 1,3 propanediol from about 1% to about 55%, water from about 3% to about 90%, natural stabilizer from about 0.1% to about 6%; solid stick—renewably-based, biodegradable 1,3 propanediol from about 15% to about 60%, water from about 40% to about 80%, natural stabilizer from about 0.06% to about 8%. The solid stick, cream and lotion embodiments may optionally contain renewably-based, biodegradable 1,3 propanediol and a natural structurant such as, for example, sodium stearate, respectively at the following weight/weight concentrations: solid stick—from about 2% to about 7%; cream—from about 0.5% to about 4%; lotion—from about 0.01% to about 2%.

The natural delivery system may be used for the topical or transdermal delivery of natural active ingredients which are well-known to cosmetic and pharmaceutical chemists, and which are listed in further detail the paragraphs below. Compositions and methods for transdermal delivery are well-known in the dermatologic, cosmetic and pharmaceutical arts and are described in U.S. Pat. No. 6,267,984, the disclosure of which is incorporated herein by reference. Some general categorical examples of such active ingredients include, but are not limited to, antioxidants, anti-wrinkle agents, vitamins, sunscreen actives, moisturizers, penetration enhancers and immuno-supportive ingredients, as well as natural cosmetic ingredients, such as pigments, colorants and fragrances of plant origin as well as colorants and pigments derived from inorganic minerals. Penetration enhancers are ingredients that enhance the ability of the cell membrane to both absorb and retain pharmacologically active agents. Sunscreen actives are organic or inorganic agents that absorb or reflect light waves over a specified spectrum, thus preventing potentially harmful erythemal ultraviolet radiation from reaching and damaging the skin. Please refer to detailed lists below for additional examples of natural active ingredients of the invention.

For purposes of the present invention, an immuno-supportive ingredient shall mean an ingredient that leads to one or more of the following physiological responses by immune cells (e.g., monocytes, macrophages, neutrophils and natural killer cells) to foreign bodies: increased production of white blood cells; mobilization of immune cells to the site of foreign invasion; enhanced phagocytosis or killing of foreign bodies; increased intracellular communication among immune cells with respect to foreign invasion; enhanced acquired immune response (i.e., by antibodies and T-cells). A preferred immuno-supportive ingredient suitable for delivery in the present invention to the glandular and lymphatic systems via percutaneous absorption through the underarm skin are 1,3 .beta. glucans. A particularly preferred 1,3 .beta. glucan has 1,3/1,6 glucose linkages, and is sold under the tradename WGP-6 by Biothera (Eagan, Minn.).
