In general, the polysaccharides employed have an average molecular weight in excess of about 19,000. Advantageously adapted are those polysaccharides which have an average molecular weight in excess of 50,000 with those having a molecular weight in excess of 100,000 providing exceptional physical properties in an aqueous s stem. Exemp ar r se molemlar. ei h s of t e polysaccharides include those having an average molecu: lar weight ranging from about 19,000. to about 300,000,-

Suitable carbohydrate source materials; for preparing the polysaccharide via the above-mentioned organisms include sucrose, D-xylose, D-mannose, D-glucose (dextrose), barabinose, D-galactose, D-tfructose, maltose, D-melezitose, rai linose, methylbetasmaltoside, Laesculin, cellobiose, trehalose, L-rhamnose, cellulose and xylanor mixtu es the eon carbohydratssource material is dissolved in an aqueous solution generally at a concentration ranging from about 3 to 15 percent by Weight along with other culture medium nutrients such as yeast extract and mineral salts contained, for example, in Czapek Dox Broth.
The organism is then added to the culture medium, the pH is adjusted between about 3-6 and the temperature is maintained between-25-35" F. (e.g., for about 3-6 days) whereby the polysaccharide is formed.
In general, the polysaccharides that are capable of being dispersed in water tofi form an aqueous viscous solution 'are'adaptable -herein (e.g., 0.5 weight percent of the polysaccharide at 20 Cl) Thus, polysaccharides from the fermentation broth (i.e.,:the fermented broth or dried productthereof) which are dispersible in water and purified forms such as disclosed in my copending Polysaccharides and 'Methods' for 'Pr'oduction'Thereof, Ser. No. 449,581 filed Apr. 20, 1965, and now abandoned or modified polysaccharides are adaptable herein.
The amount of polysaccharide. employed in a particular cosmetic preparation diifers from one cosmetic preparation to another depending uponzthe formulation. Any amount of pclysaccharide will produce some eifect upon the advantageous properties of the cosmetic composition. In general, an 'arr' oizint of polysaccharide ranging from about 0.025 to: about 10 weight percent of the total amount o'f water contained in the cosmetic product, as ultimately employed by. the consumer, is suflicient. Advantageous ly, amounts" of polysaccharide ranging from about 0.05 to about'ZLO weight percent (basedupon the total amount of water) are employed, with preferred amounts ranging 'from about 0.1 to about 2.0 Weight percent.
The term emollient as employed herein refers to cosmetic additives that areemployed in topical cosmetic preparations for preventionorrelief of dryness as well ras the protection of, skinfl n ,generahemollients are employed for their local softening, soothing, r elaxing and protective actions. 'Emollients include the all yl esters (e.g., alkyl containing from 1 to 22 carbonatoms), alcohols, ma: t'erials having fat-like properties, fatty, alcohols, fatty acids, :humectants .and preparations containing the same which are used externally to allay irritation and prevent drying of the skin. Illustrative emollients include the wax esters (.e.g., lanolin, spermaceti, beeswax); the steroid alcohols such as cholesterol, dihydrocholesterol, cerebrosterol, lanosterol, dihydrol anosterol, agnosterol, I dihydro'agnosterol and the like (e.g. Amerchol ill-101, and Nimlesterol )1; the fatty alcohols (e.g., lauryl, myristyl, cetyl, oleyl and stearyl alcohols); the triglyceridefesters, for example, the animal and vegetable fats and oilssuch as peach kernel, apricot kernel, castor, peanut, rapeseed, corn, cottonseed, soybean, tung, lard, neats foot, whale, sunflowenpalm kernal grapeseedflaxseed, seasarne, cod liver and fish: oils, and the hydrogenated oils thereof, etc., the coconut, palm, lard, tallow fats, etc.; the phosph'olipids (e.g., lecithin and cephalin); the polyh'ydrioalcohols'es'ters such as the monoevand (ii-fatty acid esters of ethylene glycol, diethylene. glycol, polyethylene glycols, propylene glyc'olgglyceryl, sorbitol, mannitol, pentaerytliritol,' 'polyonyethylene sorbitol- (e.g., polysorbates, glycer'yl monostearate, propylene glycol monosteara-te, ethylene glycol monostearate, polyethylene glyco'l monosteara'te, Spans, Arlacels the fatty alcohol others (e.g., cetyl, stearyl or oleyl-ether of ethylene oxide polymers); lower alkyl fatty esters. like methyl, isopropyl butyl esters of fatty acids (butyl stearate, isop-ropy-l stearate, isopropyl palinitate and isopropyl myristate); hydrocarbon oils and waxes such as ozokerite, mineral oil,
petrolaturn and iparafi in; ,hydrophilic lanolin derivatives,
for example, ,polyoxyethylene, sorbitol. lanolin (Atlas G-l425, (3-1441 and G-l471) and polyoxyethylene lanolin derivatives (Atlas 6-1790 and Gl795; Lanogel, Ethoxylan and Etholan fl; hydrophilic beeswax derivatives (polyethylene sorbital beeswax such as Atlas G-l702 and 6-1726); siliconoils such as Dow-Corning 200 series and 555 series and Velvasil silicon fluids; acetylated lanolin alcohols (e.g., Acetulan); acetylated lanolin (e.g., lanolin derivative in which the hydroxyl groups therein are esterified with acetic anhydrideModulan and Elfanol); alcohollanolin esters (e.g., reaction product of partial transesterification of lanolin with isopropanol such as Isopropylan; fatty acid (e.g., C -C such as stearic, oleic and palmitic acids and the like. Other emollients contemplated which control the moisture exchange between the cosmetic product and air, known to the art as humectants, include glycerol, propylene glycol, sorbitol, polyethylene glycerols, mannitol, glucose, polyethylene sorbitols and polyethylene glycols. Mixtures of emollients may also be employed.
The amount of emollient included within the cosmetic preparation of the instant invention will differ from one cosmetic preparation to another depending upon the formulation and desired product thereof. Conventional amounts of emollients are adaptable; however, the polysaccharides provide enhanced properties when lesser or greater amounts of emollients are employed. Additional benefits and effective release of the emollient is accomplished via the polysaccharide when ultimately applied by the consumer. This is due largely to the emulsifying and suspending properties thereof. In general, the amount of emmollient will range from about 0.5 to about 99 weight percent of the water contained in the cosmetic preparation. Advantageously, the amount of emollient ranges from about 3 to about 80 weight percent emollient (i.e., based upon the amount of water contained therein). For oil-soluble emollients, an illustrative amount of emollient for an oil in water cosmetic preparation would range from about 1 to about 40 weight percent emollient. Advantageously, the oil in water cosmetic preparation includes from about 3 to about 25 weight percent emollient with a preferred range of about to about weight percent. In cosmetic preparation of the water in oil type, illustrative amounts of emollient based upon the total amount of water contained therein range from about to about 99 weight percent with a preferred range of about to about 80 weight percent. The weight percents for the emollient are based on the total amount of water contained in the cosmetic preparations.
Barrier agents (i.e., cosmetic agents which, in addition to providing a rehydration of the stratum corneum, act as protectors of the skin surface) may also be included in the instant cosmetic preparations. Although the waterdispersible barrier agents such as casein, methylcellulose, sodium carboxymethylcellulose, cellulose acetate butyrate, algin and derivatives, zein, gum tragecanth, pectin, quince seed gum and the like may be employed, the use thereof is not essential since the polysaccharide will provide the necessary viscosity increase and protective coating effect when ultimately applied by the consumer. Barrier agents which are substantially insoluble in water (e.g., zinc oxide, zinc stearate, bentonite, titanium dioxide, bismuth subcarbonate, bismuth subnitrate, magnesium silicate, calamine, talc, etc.) are very suitable included in the cosmetic preparation of the instant invention. Due to suspending ability, the aqueous polysaccharide cosmetic preparations provide stable dispersions thereof which may be stored over extended periods of time without concomitant separation thereof. Moreover, upon application thereof by the consumer, the combination of the polysaccharide with the water-insoluble barrier agents provides a protective layer upon the skin which permits more effective retention thereon (e.g., such preparations are resistant to removal therefrom by water and sweat).
To prevent microbial action, a preservative is generally added to the cosmetic compositions in amounts suflicient to prevent microbial degradation (e.g., amounts of about 0.1 to 5.0%). Suitable preservatives include the conven- Antioxidants such as butylated hydroxyanisole, butylated hydroxytoluene, di-tert-p-buty1-p-cresol, 2,5-di-tertbutyl hydroquinone, propyl gallate, should accordingly be used when the cosmetic preparation contains ingredients which are prone to oxidative action.
Although the polysaccharides are odorless in aqueous solution, it has unexpectedly been discovered that the combination of the polysaccharide and perfumes conventionally added to cosmetic preparations produces an enhanced olefactory sense. Perfumes adaptable herein, inter alia, include one or more of the naturally occurring essential oils, one or more of the specific odorous synthetic organic compounds and mixtures thereof. Citronella oil, lemon oil and bois de rose oil are representative of essential oils. Phenyl ethyl alcohol, hydroxycitronella, phenyl ethyl acetate, vetiverol acetate and citronella are illustrative of specific odorous synthetic organic compounds.
Anionic, cationic, nonionic emulsifiers and/or appropriate mixtures thereof are employable in conventional amounts, however, are not necessarily included since the polysaccharide will provide emulsifying properties. Typical cosmetic emulsifiers are disclosed, for example, in Cosmetic Science and Technology by E. Sagarin, et al., Intel-science Publishers, Inc., New York (1957) (e.g., see pages 164-168 and 775-780).
' Healing agents (e.g., allantoin), hormones, coloring agents, sunscreening agents, skin lighteners and bleaching agents, antibiotics, hypoallergenic agents, deodorizing agents and other cosmetic additives in conventional amounts may also be added to the cosmetic preparations.
The recitation homogenous mixture as employed herein refers to skin compositions which are macroscopically homogenous (i.e., they are of macroscopicallyuniform consistency) and include those cosmetic skin compositions wherein the polysaccharide and water form the continuous external phase as well as skin compositions wherein the internal phase (i.e., the dispersed phase) comprises the polysaccharide and water. Cosmetic preparations ranging from solid to liquid consistency are contemplated in the instant invention.
The following examples, are illustrative of the invention:
EXAMPLE I Calamine lotion (A) Preparation of the polysaccharide.Into a sterile culture medium having an adjusted pH of 4.5 with 6 N hydrochloric acid consisting of:
Parts Distilled water 300 Sucrose 9 NaNO 0.9 K HPO 0.3 MgSO., 0.15 KCl 0.15 Autolyzed yeast 0.3 FeSO 0.003
was inoculated with a loopful of Scleron'um rolfsii Barnett, America Type Culture Collection No. 15206 and incubated for 5 days at approximately 28 C. on a rotary shaker. The resultant culture was placed in a sterile blender and set aside for use as an inoculum.
j aqueous carbohydrate source Was prepared by dissolving the following ingredients in 500 gallons of water:
The pH of the resulting medium was adjusted to 4.5 with hydrochloric acid and then heated for 20 minutes at 15 psi. at 250 F.
After the cultured medium had cooled, 100 pounds of the previously prepared homogenized inoculum was added to the fermenter vessel equipped with variable speed agitation, a'sterile air supply and temperature control means. An antif oam agent was added (e.g., octyldecanol) The medium was incubated for days at a temperature of 28 F. and at an agitation rate of 96 r.p.m. and an aeration rate of 0.8 vol./vol. of medium per minute. The fermentate was then removed into another vessel to which 1,500 gallons of water was added. After thorough mixing, the diluted fermentate was heated to approximately 90 to 95 C., cooled, and then filtered via a diatomaceous earth filter for removal of mold cells.
To the filtrate an equal volume of methanol was added and mixed therein. Within a few minutes, the polysaccharide product rose to the surface and was removed therefrom by skimming. The polysaccharide was washed twice with methanol and then dried in an oven at 50 C. The resultant fibrous mat of polysaccharide was then comminuted to a fine powder.
Polysaccharide chemical and physical results Viscosity of aqueous solutions.--After 24 hours (Brookfield viscometer-23 C.30 r.p.m.3 spindle) Cps. 1.0% 2200 1.25% 3280 1.5% About 4400 7 Additional information relating to the preparation of other polysaccharides andpolysaccharides thereof is disclosed in my copending appliaction, Ser. No. 449,581.
(B) Preparation of the calamine 1otion.-Ten grams of the polysaccharide prepared in accordance with the foregoing Example 1A was dispersed in 600 ml. of water and stirred vigorously for 5 minutes with a mechanical stirrer. An aqueous polysaccharide suspension was formed by adding to the aqueous polysaccharide 0.5 gram pigment dispersant (condensed aryl sulfonic acid-Tamo1 SN) followed by moderate stirring with a mechanical stirrer for an additional 5 minutes. An admixture of zinc oxide and calamine powder was prepared by admixing 50 grams of zinc oxide and 150 grams of calamine powder. The admixture was then placed in a mortar. Fifty ml. .of glycerol wasadded to the admixture and blended therein via a mortar and pestle means. A sufficient amount of the aqueous polysaccharide was slowly added to the blended admixture with continued blending thereof until a resultant smooth paste state was obtained. The resultant smooth paste was then added to the remaining aqueous polysaccharide suspension and stirred vigorously via a mechanical stirrer for 5 minutes. Five ml. of phenol was added after which the 400 ml. of water was added followed by continued stirring for an additional 5 minutes.
The resultant calamine lotion was then poured-into a:
For comparative purposes, another calamine lotionwas prepared by employing thev above-mentioned method ex-' cepting that 10 grams of carboxymethyl'cellulose was'employed in lieu of the polysaccharide. It was observed that the polysaccharide'exhibited an enhanced elf'ect in the mixing of" the ;zinc oxide and calamine in contradistinction to the calamine lotion con taining the carboxymethylcellulose. The carboxymethyl-; cellulose product remained. more dense and took longer to reach a smooth paste state whereas the polysaccharide calamine lotionrapidly exhibited'a smooth, light, fluffy like paste texture. After 5 hours of storage, the carboxy.-. methylcellulose product had a pronounced sedimentation layer whereas no such layer was observed in the poly-' saccharide product. Also, a thin, semi-opaque, upper, water layer (about 6% of the total volume) was definitely observable in the carboxymethylcellulose product whereas no observable change in the internal characteristics of polysaccharide was notedThirty days after storage under ambient conditions, the upper water-like layer of the carboxymethylccllulose increased to about 10% of the total volume with a corresponding nonobservable change in the polysaccharide calamine lotion. The polysaccharide calamine lotion wetted' and covere the skin with greater ease than the lotion containing carboxymethylcellulose. After application to the skin and drying thereof, it was observed that the carboxymethylcellulose product streaked and washed off when'subjected to fast-flowing streams of cold water (about 20 C.) from an ordinary household faucet. Under similar conditions, the applied polysaccharide calamine lotion formed a film which did not streak or wash off, however, could readily be removed by mild scrubbing action.
EXAMPLE H Hand lotion The following four phases were prepared by admixing the following phase ingredients:
Phase 30.5 weight percent aqueous polysaccharide solution 308.0 Phase 4:
Alcohol 50.0 Lotion fragrance No. 2246E Example 1A polysaccllaride. I I The hand lotion was then prepared by separately heating Phases 1, 2 and 3 to C. Phase 1 was then added to Phase 2 followed'by vigorous agitation. After thorough agitation and with continued agitation Phase 3 was added. The resultantadmixture of Phases 1, 2 and 3 was then cooled to 36 C. and Phase 4 was added while maintaining agitation. Agitation was then continuedfor 20 minutes. Water loss due to evaporation was then compensated for (i.e., original volume thereof) by the addition of water. To insure uniform mixtures, agitation was then continued for 1 hour.
Viscosity of the resultant hand lotion was 2200 cps. as ascertained by a Brookfield Viscometer, No.=.3 Spindle at 23 C. operated at 30 rpm. The hand-lotion provided a softening effect to the hands and flowed evenly and with ease when applied thereon.
After storage for one year in a closed bottle under ambient conditions, the hand lotion still maintained a good consistency and appearance without concomitant separation of the various ingredients therein.
