Description
    FIELD OF THE INVENTION
  • [0001]
    The present invention relates to multi-phase personal cleansing compositions comprising at least one structured aqueous cleansing phase and at least one additional, non-lamellar aqueous phase wherein at least one of the phases comprises at least one non-migrating colorant comprising a cLogP value of at least about 2 and wherein the two phases are packaged in physical contact with one another while remaining stable over time.
  • BACKGROUND OF THE INVENTION
  • [0002]
    The ability to place a cleansing phase in physical contact with a structured aqueous phase and maintain stability for any period of time has proven to be a problem. The physical contact of a structured aqueous phase and a cleansing phase creates a situation where they are thermodynamically unstable.
  • [0003]
    One attempt at providing a stable, structured aqueous phase and cleansing phase within a personal cleansing product would be the use of dual-chamber packaging. These packages comprise separate cleansing compositions and structured aqueous compositions, and allow for the co-dispensing of the two in a single or dual stream. The separate structured aqueous composition and cleansing compositions thus remain physically separate and stable during prolonged storage and just prior to application, but then mix during or after dispensing to provide conditioning and cleansing benefits from a physically stable system. Although such dual-chamber delivery systems provide improved cleansing benefits versus conventional systems, it is often difficult to achieve consistent and uniform performance because of the uneven dispensing ratio between the cleansing phase and the structured aqueous phase. Additionally, these packaging systems add considerable cost to the finished product.
  • [0004]
    Another attempt at providing a cleansing and moisturizing benefit composition has been to formulate and package such compositions as disclosed in U.S. Pat. No. 6,534,456 issued to Hayward et al., on Mar. 18, 2003 describing extrudable multi-phase compositions comprising a lamellar phase and an isotropic phase. These exemplified compositions, however, contain water soluble colorants which tend to migrate from one phase to the other. The colorant can be a meaningful aspect of the product to the consumer, connoting both benefit and performance. For a multi-phase system, the colorant can serve to distinguish the two phases from each other. Traditionally, water soluble colorants, i.e. dyes, have been used to color cleansing systems. It has, however, been found that when the compositions of the two phases are chemically distinct, as described herein, color migration of certain commonly used colorants will serve to render multi-phase compositions less visibly distinct which, may decrease their appeal. Stability is integral in such application and thus, there still remains a need for a stable personal cleansing composition that provides cleansing and skin benefits patterned in physical contact within the same package.
  • SUMMARY OF THE INVENTION
  • [0005]
    The present invention relates to a multi-phase personal cleansing compositions comprising a structured aqueous cleansing phase and at least one aqueous phase wherein at least one phase comprises a non-migrating colorant. The phases are packaged in physical contact with one another. It has been found that the use of a non-migrating colorant comprising a cLogP value of at least about 2 provides improved color stability within the product by preventing migration of the colorant between the phases.
  • [0006]
    Specifically, the present invention is directed to a multi-phase personal cleansing composition comprising: (a) a structured aqueous cleansing phase comprising a surfactant and water; and (b) at least one additional aqueous phase; wherein at least one of said structured aqueous cleansing phase and said additional aqueous phase comprises at least one non-migrating colorant, said non-migrating colorant comprising a cLogP value of at least about 2; and wherein said structured aqueous cleansing phase and said additional phase are packaged in physical contact with one another.
  • [0007]
    The present invention is also directed to a multi-phase personal cleansing composition comprising a) a structured aqueous cleansing phase comprising a surfactant and water; and b) at least one additional aqueous phase; wherein at least one of said structured aqueous cleansing phase and said additional aqueous phase comprises at least one non-migrating colorant, said non-migrating colorant having a cLogP value of at least about 2 and said non-migrating colorant being free of titanium dioxide; and wherein said structured aqueous cleansing phase and said additional phase are packaged in physical contact with one another.
  • DETAILED DESCRIPTION OF THE INVENTION
  • [0008]
    The multi-phase personal cleansing compositions of the present invention may comprise at least one structured aqueous cleansing phase and at least one additional aqueous phase, which may be a non-lamellar aqueous phase wherein at least one of the phases comprises at least one non-migrating colorant comprising a cLogP value of at least about 2 and wherein the two phases are packaged in physical contact with one another while improving color stability within the product by preventing migration of the colorant between the phases. While not necessary that the additional aqueous phase be non-lamellar, it is preferred that if the additional aqueous phase is a lamellar phase, the additional aqueous phase should also be free of titanium dioxide.
  • [0009]
    The compositions of the present invention further provide superior aesthetics via the multi-phased appearance and improved skin feel during and after application. It has been found that such compositions can be formulated into two separate hydrophilic phases in physical contact without compromising product performance and stability.
  • [0010]

All such weights as they pertain to listed ingredients are based on the active level and, therefore, do not include solvents or by-products that may be included in commercially available materials, unless otherwise specified. The term “weight percent” may be denoted as “wt. %” herein. Except where specific examples of actual measured values are presented, numerical values referred to herein should be considered to be qualified by the word “about”.
  • [0011]
    All molecular weights as used herein are weight average molecular weights expressed as grams/mole, unless otherwise specified.
  • [0012]
    As used herein, “comprising” means that other steps and other ingredients which do not affect the end result can be added. This term encompasses the terms “consisting of” and “consisting essentially of”.

  • [0013]
    By the term “multi-phased” or “multi-phase”, it is meant that the structured aqueous cleansing phase and the additional aqueous phase herein occupy separate but distinct physical spaces inside the package in which they are stored, but are in direct contact with one another (i.e., they are not separated by a barrier and they are not emulsified or mixed to any significant degree). In the present invention, the “multi-phase” personal cleansing compositions comprising structured aqueous cleansing phase and at least one additional aqueous phase are present within the container as a visually distinct pattern. The pattern results from the mixing or homogenization of the “multi-phased” composition. The patterns include but are not limited to the following examples: striped, marbled, rectilinear, interrupted striped, check, mottled, veined, clustered, speckled, geometric, spotted, ribbons, helical, swirl, arrayed, variegated, textured, grooved, ridged, waved, sinusoidal, spiral, twisted, curved, cycle, streaks, striated, contoured, anisotropic, laced, weave or woven, basket weave, spotted, and tessellated. The pattern may be striped and may be relatively uniform and even across the dimension of the package. Alternatively, the striped pattern may be uneven, i.e. wavy, or may be non-uniform in dimension. The striped pattern does not need to necessarily extend across the entire dimension of the package. The size of the stripes is at least about 0.1 mm in width and 10 mm in length, preferably at least about 1 mm in width and at least 20 mm in length. The phases can form various geometric shapes, be various different colors, or include glitter or pearlescence.
  • [0014]
    The term “ambient conditions” as used herein, refers to surrounding conditions at one (1) atmosphere of pressure, 50% relative humidity, and 25° C.
  • [0015]
    The term “stable” as used herein, unless otherwise specified, refers to compositions that maintain at least two “separate” phases when sitting in physical contact at ambient conditions for a period of at least about 180 days. By “separate”, it is meant that there is substantially no mixing of the phases that are observable to the naked eye prior to dispensing of the composition.
  • [0016]
    The term “personal cleansing composition” as used herein, refers to compositions intended for topical application to the skin or hair.
  • [0017]
    The term “phases” as used herein, refers to a region of a composition having one average composition, as distinct from another region having a different average composition, wherein the regions are visible to the naked eye. This would not preclude the distinct regions from comprising two similar phases where one phase could comprise pigments, dyes, particles, and various optional ingredients, hence a region of a different average composition.
  • [0018]
    The phrase “substantially free of” as used herein, means that the composition comprises less than about 3%, less than about 1%, less than about 0.5%, less than about 0.25%, or less than about 0.1%, by weight of the composition, of the stated ingredient.
  • [0019]
    The phrase “UV stable” as used herein, means stable to UV light exposure. For example, exposure of a composition in a transparent or translucent package to UV light in a Fadometer which utilizes a water cooled xenon lamp to simulate sunlight exposure does not significantly fade the color of the product as determined by a side by side comparison of before and after exposure to 6 hours of light (simulating 30 days sunlight), which can also be determined by having a low delta Ecmc of the colored phase (e.g., delta E may be less than 5, less than 4, less than 3, or less than 2 for a 0.012% colorant slurry in a 60% petrolatum, 39.88% Hydrobrite 1000™ mineral oil mixture).

  • [0000]
    Non-Migrating Colorant
  • [0054]
    The multi-phase personal cleansing composition comprises a non-migrating colorant in at least one of the phases of the multi-phase personal cleansing composition. The composition may comprise from about 0.00001%, from about 0.001%, or from about 0.005% to about 10%, to about 1%, to about 0.1%, or to about 0.05%, by weight of the composition of a non-migrating colorant.
  • [0055]
    To enhance the aesthetic qualities of the present invention, it is important that the non-migrating colorants incorporated into at least one of the phases remain stable and do not migrate from one phase to the other. The Partition Coefficient Values (cLogP) reflect a molecule's hydrophilicity and thus the cLogP calculations are considered for the present invention to determine if they are appropriate to resist migration within the particular phases of the present invention. The cLogP calculations of the present invention reflect the log ratio of the equilibrium concentrations of solute when placed at an n-Octanol (non-polar)-water(polar) system. Hydrophilic colorants are polar which enable them to perform hydrogen bonding and dissolve more readily in water. More hydrophobic colorants, however, favor the n-Octanol phase which effectively increases the cLogP value. Less water soluble colorants also tend to increase the cLogP value due to decreased water solubility. It has been found that colorant materials with a cLogP greater than 2 will resist migration in multi-phase aqueous compositions. Many of these materials with this property are not traditionally used to color personal cleansing compositions and so would not be normally be used by one skilled in the art.
  • [0056]
    cLogP can be calculated for a variety of commercial compositions with relatively good agreement between the protocols. According to the present invention, the protocol from ACD Labs website was used (www.acdlabs.com). In some cases, where the colorant contains ionizable groups, cLogD (variation of cLogP with pH) can be used at the relevant composition pH.
  • [0057]
    Accordingly, the non-migrating colorants of the present invention may comprise a cLogP value of at least about 2, at least about 3, at least about 4, or at least about 5. Certain non-migrating colorant materials, however, are effectively insoluble in either phase thus making it difficult to calculate a cLogP value. These non-migrating colorant materials may include, but are not limited to, metal oxides (i.e., iron oxides, titanium dioxide) and micas. Due to their limited water solubility, however, it is understood that the cLogP value will be significantly increased and are considered to have a value greater than about 5 which makes them applicable to the present invention.
  • [0058]
    While the non-migrating colorants of the present invention may comprise metal ions, i.e. lakes, it is preferred that the non-migrating colorants remain free of barium and aluminum ions to allow for improved lamellar phase stability. The non-migrating colorants may also maintain UV stability.
  • [0059]
    The non-migrating colorants for use in the multi-phase personal cleansing compositions of the present invention may be selected from the group consisting of organic pigments, inorganic pigments, interference pigments, lakes, natural colorants, pearlescent agents, dyes, carmines, and mixtures thereof.
  • [0060]
    In the case of lakes, which are colorant materials physi- or chemisorbed onto a substrate (such as talc), the cLogP of the colorant material itself is considered to be the key parameter. For instance, in the table below, the relevant cLogP for D&C Red 30 Talc lake and aluminum lake are identical because it is the cLogP of the Red 30 which is calculated.
  • [0061]
    Non-limiting examples of non-migrating colorants along with their cLogP values are charted accordingly:

  • [0065]
    Suitable cationic deposition polymers for use in the multi-phase personal cleansing composition of the present invention contain cationic nitrogen-containing moieties such as quaternary ammonium or cationic protonated amino moieties. The cationic protonated amines can be primary, secondary, or tertiary amines (preferably secondary or tertiary), depending upon the particular species and the selected pH of the personal cleansing composition.

  • [0066]
    Non-limiting examples of cationic deposition polymers for use in the personal cleansing composition include polysaccharide polymers, such as cationic cellulose derivatives. Preferred cationic cellulose polymers are the salts of hydroxyethyl cellulose reacted with trimethyl ammonium substituted epoxide, referred to in the industry (CTFA) as Polyquaternium 10™ which are available from Amerchol Corp. (Edison, N.J., USA) in their Polymer KG, JR and LR series of polymers with the most preferred being KG-30M™.

    The concentration of the cationic polymer in the cleansing composition may be from about 0.025%, from about 0.1%, or from about 0.2% to about 5%, to about 3%, or to about 1%, by weight of the composition.
  • [0070]
    A non-limiting example of a commercially available synthetic cationic polymer for use in the cleansing compositions is polymethyacrylamidopropyl trimonium chloride, available under the trade name Polycare 133™, from Rhodia, Cranberry, N.J., U.S.A.
  • [0071]
    The cationic polymers herein are either soluble in the structured aqueous cleansing phase, or are soluble in a complex coacervate phase in the multi-phase personal cleansing composition formed by the cationic deposition polymer and the anionic surfactant component described hereinbefore. Complex coacervates of the cationic deposition polymer can also be formed with other charged materials in the personal cleansing composition.
  • [0072]
    Coacervate formation is dependent upon a variety of criteria such as molecular weight, component concentration, and ratio of interacting ionic components, ionic strength (including, modification of ionic strength, for example, by addition of salts), charge density of the cationic and anionic components, pH, and temperature. Coacervate systems and the effect of these parameters have been described, for example, by J. Caelles, et al., “Anionic and Cationic Compounds in Mixed Systems”, Cosmetics & Toiletries, Vol. 106, April 1991, pp 49-54, C. J. van Oss, “Coacervation, Complex-Coacervation and Flocculation”, J. Dispersion Science and Technology, Vol. 9 (5,6), 1988-89, pp 561-573, and D. J. Burgess, “Practical Analysis of Complex Coacervate Systems”, J. of Colloid anti Interface Science, Vol. 140, No. 1, November 1990, pp 227-238.
  • [0073]
    It is believed to be particularly advantageous for the cationic deposition polymer to be present in the personal cleansing composition in a coacervate phase, or to form a coacervate phase upon application or rinsing of the cleansing composition to or from the skin. Complex coacervates are believed to more readily deposit on the skin, which results in improved deposition of the benefit materials. Thus, in general, it is preferred that the cationic deposition polymer exists in the personal cleansing composition as a coacervate phase or forms a coacervate phase upon dilution. If not already a coacervate in the personal cleansing composition, the cationic deposition polymer will preferably exist in a complex coacervate form in the cleansing composition upon dilution with water.
  • [0074]
    Techniques for analysis of formation of complex coacervates are known in the art. For example, centrifugation analyses of the personal cleansing compositions, at any chosen stage of dilution, can be utilized to identify whether a coacervate phase has formed.

These materials can be used at ranges sufficient to provide the required benefit, as would be obvious to one skilled in the art.
  • [0076]
    The multi-phase personal cleansing compositions of the present invention can additionally comprise an electrolyte. When present, the electrolyte used in the structured aqueous cleansing phase may be the same as the electrolyte used in the additional aqueous phase. The amount of electrolyte in the individual phases is determined relative to the amount of water. For example for a composition with 2% NaCl and 50% water by weight, the amount of electrolyte may be about 4%. The amount of electrolyte in the structured aqueous cleansing phase may be more than about 0.1%, more than about 0.5% or more than about 1%. When both the structured aqueous cleansing phase and the additional aqueous phase comprise electrolyte, the level of electrolyte in the structured aqueous cleansing phase may be at least about 30%, at least about 40%, at least about 50%, or at least about 75% of the amount of electrolyte added to the additional aqueous phase. The level of electrolyte in the structured aqueous cleansing phase may be less than about 150%, less than about 130%, or less than about 120% of the amount of electrolyte added to the additional aqueous phase.

    Test Methods
  • [0000]
    Viscosity Method
  • [0079]
    The viscosity of the individual phase is determined using a Brookfield DVII+ Pro Viscometer with a helipath attachment using a D spindle at 5 rpm. The sample is loaded into a container with a diameter greater than 2.5″ and allowed to equilibrate for at least 12 hours. Prior to reading, the spindle is inserted into the sample to a depth of approximately ź″ and the rotation is begun and the helipath turned on with the direction adjusted to increase the penetration of the spindle into the sample. The viscometer is set up to readout every second, and the first 10 seconds are ignored. The next 5 data points are recorded and averaged to obtain the viscosity.
  • [0000]
    Lather Volume
  • [0080]
    Lather volume of a personal care composition can be measured using a graduated cylinder and a tumbling apparatus. A 1,000 ml graduated cylinder is chosen which is marked in 10 ml increments and has a height of 14.5 inches at the 1,000 ml mark from the inside of its base (for example, Pyrex No. 2982). Distilled water (100 grams at 23° C.) is added to the graduated cylinder. The cylinder is clamped in a rotating device, which clamps the cylinder with an axis of rotation that transects the center of the graduated cylinder. One gram of the total personal care composition is added into the graduated cylinder and the cylinder is capped. The cylinder is rotated at a rate of 10 revolutions in about 20 seconds, and stopped in a vertical position to complete the first rotation sequence. A timer is set to allow 30 seconds for the lather thus generated to drain. After 30 seconds of such drainage, the first lather volume is measured to the nearest 10 ml mark by recording the lather height in ml up from the base (including any water that has drained to the bottom on top of which the lather is floating).
  • [0081]
    If the top surface of the lather is uneven, the lowest height at which it is possible to see halfway across the graduated cylinder is the first lather volume (ml). If the lather is so coarse that a single or only a few foam cells (“bubbles”) reach across the entire cylinder, the height at which at least 10 foam cells are required to fill the space is the first lather volume, also in ml up from the base. Foam cells larger than one inch in any dimension, no matter where they occur, are designated as unfilled air instead of lather. Foam that collects on the top of the graduated cylinder but does not drain is also incorporated in the measurement if the foam on the top is in its own continuous layer, by adding the ml of foam collected there using a ruler to measure thickness of the layer, to the ml of foam measured up from the base. The maximum foam height is 1,000 ml (even if the total foam height exceeds the 1,000 ml mark on the graduated cylinder). One minute after the first rotation is completed, a second rotation sequence is commenced which is identical in speed and duration to the first rotation sequence. The second lather volume is recorded in the same manner as the first, after the same 30 seconds of drainage time. A third sequence is completed and the third lather volume is measured in the same manner, with the same pause between each for drainage and taking the measurement.
  • [0082]
    The lather result after each sequence is added together and the Total Lather Volume determined as the sum of the three measurements, in ml. The Flash Lather Volume is the result after the first rotation sequence only, in ml, i.e., the first lather volume. For cleansing applications the personal care compositions may produce a Total Lather Volume of at least about 300 ml or greater than about 600 ml as described in the Lathering Volume Test. The personal care compositions may produce a Flash Lather Volume of at least about 100 ml, greater than about 200 ml, or greater than about 300 ml as described in the Lathering Volume Test.
  • [0000]
    Method of Use
  • [0083]
    The multi-phase personal cleansing compositions of the present invention are preferably applied topically to the desired area of the skin or hair in an amount sufficient to provide effective delivery of the skin cleansing agent and skin benefit agents to the applied surface. The compositions can be applied directly to the skin or indirectly via the use of a cleansing puff, washcloth, sponge, or other implement. The compositions are preferably diluted with water prior to, during, or after topical application, and then subsequently rinsed or wiped off of the applied surface, preferably rinsed off of the applied surface using water or a water-insoluble substrate in combination with water.
  • [0084]
    The present invention is therefore also directed to methods of cleansing the skin through the above-described application of the compositions of the present invention.

    Method of Manufacture
  • [0085]
    The multi-phase personal cleansing compositions of the present invention may be prepared by any known or otherwise effective technique, suitable for making and formulating the desired multi-phase product form. It is effective to combine toothpaste-tube filling technology with a spinning stage design. Additionally, the present invention can be prepared by the method and apparatus as disclosed in U.S. Pat. No. 6,213,166, U.S. Pat. No. 4,159,028, or US Publication No. 2004/0219119. The method and apparatus allows two or more compositions to be filled with a spiral configuration into a single container. The method requires that at least two nozzles be employed to fill the container. The container is placed on a static mixer and spun as the composition is introduced into the container.
  • [0086]
    Alternatively, it is effective to combine at least two phases by first placing the separate compositions in separate storage tanks having a pump and a hose attached. The phases are then pumped in predetermined amounts into a single combining section. Next, the phases are moved from the combining sections into the blending sections and the phases are mixed in the blending section such that the single resulting product exhibits a distinct pattern of the phases. The pattern is selected from the group consisting of striped, marbled, geometric, and mixtures thereof. The next step involves pumping the product that was mixed in the blending section via a hose into a single nozzle, then placing the nozzle into a container and filing the container with the resulting product.
  • [0087]
    If the personal cleansing compositions contain stripes of varying colors it can be desirable to package these compositions in a transparent or translucent package such that the consumer can view the pattern through the package. Because of the viscosity of the subject compositions it may also be desirable to include instructions to the consumer to store the package upside down, on its cap to facilitate dispensing.
