Description

NON-MIGRATORY COLORANTS IN MULTIPLE PHASE COMPOSITIONS FOR PERSONAL CLEANING FIELD OF THE INVENTION The present invention relates to multi-phase personal cleansing compositions comprising at least one structured aqueous cleansing phase and at least one additional, non-laminar aqueous phase wherein at least one of the phases comprises at least one non-migratory dye comprising a clogP value of at least about 2, and wherein the two phases are packaged with physical contact with each other while remaining stable for a time.

BACKGROUND OF THE INVENTION The ability to place a cleansing phase in physical contact with a structured aqueous phase and maintain stability during any period of time has proven problematic. The physical contact of a structured aqueous phase and a cleansing phase creates a situation where they are thermodynamically unstable. An attempt to provide an aqueous, structured, stable phase and a cleaning phase within a personal cleansing product would be the use of a double chamber packaging. These containers they comprise separate cleaning compositions and structured aqueous compositions, and allow the co-dispatch of the two compositions in a single or double stream. The separated structured aqueous composition and the cleaning compositions, in this way remain physically separate and stable during prolonged storage and just before application, but are then mixed during or after shipment to provide cleaning and conditioning benefits from a system physically stable. Although double chamber supply systems provide improved cleaning benefits compared to conventional systems, it is often difficult to achieve consistent and uniform performance because of the unequal ratio of clearance between the cleaning phase and the structured aqueous phase. Additionally, these packaging systems greatly increase the cost of the finished product. Another attempt to provide a composition with a cleansing and moisturizing benefit has been to formulate and package the compositions as described in U.S. Pat. no. 6,534,456 issued to Hayward et al., March 18, 2003, which describes the extrudable multi-phase compositions comprising a lamellar phase and an isotropic phase. These illustrated compositions, however, contain water-soluble dyes that tend to migrate from one phase to another. The colorant can be a significant aspect of the product for the consumer, which implies both benefit and performance. For a multi-phase system, the dye can serve to distinguish the two phases from one another. Traditionally, Water-soluble dyes, that is, dyes, have been used to color cleaning systems. It has been found, however, that when the compositions of the two phases are chemically distinct, as described herein, the color migration of certain commonly used dyes will serve to obtain visibly less distinct multi-phase compositions that can decrease its attractiveness The stability is integral in that application and therefore, there is still a need for a stable personal cleansing composition, which provides cleansing and benefits for the skin, configured in physical contact within the same container.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to 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-migratory dye. The phases are packaged with physical contact with each other. It has been found that the use of a non-migratory dye comprises a cLogP value of at least about 2, provides improved color stability within the product, preventing migration of the dye between the phases. Specifically, the present invention is directed to a multi-phase composition for personal cleansing 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 the structured aqueous cleansing phases, and the additional aqueous phase, comprise at least one non-migratory dye, that non-migratory dye comprises a clogP value of at least about 2; and wherein the structured aqueous cleaning phase and the additional phase are packaged with physical contact with each other. The present invention is also directed to a multi-phase composition for personal cleansing 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 the structured aqueous cleansing phases and the additional aqueous phase comprise at least one non-migratory dye, that non-migratory dye has a clogP value of at least about 2, and the non-migratory dye is free of titanium dioxide , and wherein the structured aqueous cleaning phase and the additional phase are packaged with physical contact with each other.

While it is not necessary for the additional aqueous phase to 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. The compositions of the present invention further provide improved aesthetics through the appearance of multiple phases and a better skin feel during and after their application. It has been found that the compositions can be formulated within two separate hydrophilic phases with physical contact, without compromising the performance and stability of the product.

By the term "multi-phase" or "multi-phase", it is understood that the structured aqueous cleaning phase and the additional aqueous phase in the present, they occupy separate but distinct physical spaces within the container where they are stored, but they are in direct contact with each other (that is, they are not separated by a barrier and they are not emulsified or mixed in any significant degree). In the present invention, 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 is obtained by mixing or homogenizing the "multi-phase" composition.

Non-migratory dye The multi-phase composition for personal cleansing comprises a non-migratory dye in at least one of the phases of the multi-phase composition for personal cleansing.

To improve the aesthetic qualities of the present invention, it is important that the non-migratory dyes incorporated in at least one of the phases, remain stable and do not migrate from one phase to another. The values of the partition coefficient (cLogP) reflect the hydrophilicity of a molecule and therefore, the cLogP calculations for the present invention are considered as those that determine if they are appropriate to resist migration within the specific phases of the invention. present invention. The cLogP calculations of the present invention reflect the log relationship of the equilibrium concentrations of the solute when placed in a n-octanol (non-polar) -water system (polar). The hydrophilic dyes are polar, which allows them to perform the hydrogen bond and dissolve more quickly in water. More hydrophobic dyes, however, favor the n-octanol phase, which effectively increases the clogP value. The less water soluble dyes also tend to increase the clogP value, due to the reduced solubility in water. It has been discovered that the materials dyes with a cLOGP greater than 2, will resist migration into the multi-phase aqueous compositions. Many of these materials with this property are not traditionally used to color personal cleansing compositions, and therefore, could not normally be used by an experienced in the industry. The cLogP can be calculated for a variety of commercial compositions with a relatively good agreement between the protocols. In accordance with the present invention, the protocol of the ACD Labs website (www.acdlabs.com) was used. In some cases, where the dye contains ionizable groups, the cLogD (variation of cLogP with pH) can be used as the relevant pH of the composition. Accordingly, the non-migratory dyes 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-migratory dye materials, however, are effectively insoluble in both phases, thus making it difficult to calculate a clogP value. These non-migratory coloring materials may include, but are not limited to, metal oxides (ie, iron oxides, titanium dioxide) and micas. Due to its limited solubility in water, however, it is understood that the clogP value will be significantly increased and considered to have a value greater than about 5, which makes them applicable to the present invention.

Although the non-migratory dyes of the present invention can comprise metal ions, ie lacquers, it is preferred that the non-migrating dyes remain free of barium and aluminum ions to allow improved stability of the lamellar phase. Non-migratory dyes can also maintain the stability to ultraviolet light. The non-migratory dyes 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, lacquers, natural dyes, pearlizing agents, dyes, carmines, and mixtures of these. In the case of lacquers, which are physically or chemically absorbed coloring materials on a substrate (such as talcum powder), the clog of the same coloring material is considered as a key parameter. For example, in the table below, the cLogP relevant for D &C red lacquer talc 30 and aluminum lacquer are identical because the cLogP of red 30 is calculated. Non-limiting examples of non-migratory dyes together with their values ClogPs are followed closely as appropriate: Optional ingredients A variety of optional ingredients can be employed in the structured aqueous cleaning phase and in the additional aqueous phase. Non-limiting examples of optional ingredients include humectants and solutes. A variety of humectants and solutes with a concentration of about 0.1%, about 0.5%, or about 2% to about 50%, about 35%, or about 20%, by weight of the personal care composition can be employed. .

The concentrations of the cationic deposition polymer can vary from about 0.025%, from about 0.05%, or from about 0.1% to about 3%, to about 2%, or to about 1%, by weight of the composition. Cationic deposition polymers suitable for use in the multi-phase personal cleansing composition described in the present invention contain cationic portions containing nitrogen, such as quaternary ammonium portions or protonated cationic amines. The protonated cationic amines may be primary, secondary or tertiary amines (preferably secondary or tertiary) depending on the specific species and the pH chosen for the personal cleansing composition. The average molecular weight of the cationic deposition polymer can be from about 5000%, from about 100,000%, or from about 200,000 to about 10 million, to about 2 million, or approximately 1.5 million. The polymers also have a cationic charge density ranging from about 0.2 meq / gr, about 0.4 meq / gr, or about 0.6 meq / gr to about 5 meq / gr, with the expected use pH of the personal cleansing composition, whose pH will generally vary from about pH 4 or from about pH 5 to about pH 9 or about pH 8. 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 hydroxyethylcellulose salts reacted with substituted trimethylammonium epoxide, mentioned in the industry (CTFA) as polyquaternium., which are distributed by Amerchol Corp. (Edison, N.J., USA) in their polymer KG, JR and LR series of polymers, with KG-30M ™ being the most preferred. Other suitable cationic deposition polymers include cationic guar gum derivatives, such as guar hydroxypropyltrimonium chloride, specific examples of which include the Jaguar series (preferably Jaguar C-17 ™) commercially available from Rhodia Inc., and N-Hance series ™ of commercially available polymers from Aqualon.

The concentration of the cationic polymer in the cleaning composition can 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. A non-limiting example of the synthetic cationic polymer commercially available for use in cleaning compositions is polymethylacrylamidopropyl trimonium chloride, which is available under the tradename Polycare 133 from Rhodia, Cranberry, N.J., USA. The cationic polymers herein are either soluble in the structured aqueous cleaning phase, or they 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 above. The complex coacervates of the cationic deposition polymer can also be formed with other charged materials in the personal cleansing composition. The formation of the coacervate depends on a variety of criteria, such as the molecular weight, the concentration of the component, the index of the ionic interaction components, the ionic strength (including the modification of the ionic strength, for example, by the addition of salts), the charge density of the cationic and anionic components, the pH, and the temperature. Coacervate systems and the effect of these parameters are described, for example, in J. Caelles et al., "Anionic and Cationic Compounds in Mixed Systems", Cosmetics & Toiletries (Cosmetics and toiletries), Vol. 106, April 1991, p. 49-54, C. J. van Oss; "Coacervation, Complex-Coacervation and Flocculation" (Coacervation, complex-coacervation and flocculation), J. Dispersion Science and Technology, Vol. 9 (5.6), 1988-89, p. 561-573 and D. J. Burgess; "Practical Analysis of Complex Coacervate Systems "(Practical Analysis of Complex Coacervate Systems), J. of Colloid anti Interface Science (Colloid Anti-interference Science Journal), Vol. 140, No. 1, November 1990, page 227-238 It is thought to be particularly advantageous if the cationic deposition polymer is present in the personal cleansing composition in a coacervate phase, or which forms a coacervate phase when the cleansing composition is applied to the skin or rinsed therefrom. that the complex coacervates are deposited more easily on the skin, which results in a better deposition of the beneficial materials.Therefore, it is generally preferred that the cationic deposition polymer exists in the personal cleansing composition as a coacervate phase. or that forms a coacervate phase in dilution.If it is not yet a coacervate in the personal cleansing composition, the polymer of Cationic deposition will preferably exist in the form of complex coacervate in the cleaning composition in dilution with water. The techniques for the analysis of complex coacervate formation are known in the industry. For example, centrifugation analyzes of personal cleansing compositions can be used at any chosen stage of dilution to identify whether a coacervate phase has been formed. Other non-limiting examples of these optional ingredients include vitamins and derivatives thereof (eg, ascorbic acid, vitamin E, tocopherol acetate, and the like); Sunscreens; Thickening agents (eg, polyol alkoxy ester, available as Crothix from Croda); preservatives to maintain the antimicrobial integrity of the cleaning compositions (eg, DMDMH); anti-acne medications (resorcinol, salicylic acid, and the like); antioxidants; globules; sedation and skin healing agents such as aloe extract, allantoin and the like; chelating agents and sequestering agents; and agents suitable for aesthetic purposes, such as fragrances, essential oils, skin sensitizers, pigments, pearlizing agents (eg, mica and titanium dioxide), and the like (eg, clove oil, menthol, camphor) , eucalyptus oil, and eugenol). It will be obvious to one experienced in the industry that these materials can be used in the quantities necessary to provide the desired benefit. The multi-phase compositions for personal cleansing of the present invention may additionally comprise an electrolyte.

When present, the electrolyte used in the structured aqueous cleaning phase may be the same as the electrolyte used in the additional aqueous phase. The amount of electrolyte in the individual phases is determined comparatively with the amount of water. For example, for a composition with 2% NaCl and 50% water by weight, the amount of electrolyte can be about 4%. The amount of electrolyte in the structured aqueous cleaning phase can be more than about 0.1%, more than about 0.5% or more than about 1%. When both the structured aqueous cleaning phase and the additional aqueous phase comprise an electrolyte, the concentration of the electrolyte in the structured aqueous cleaning phase can 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 electrolyte concentration in the structured aqueous cleaning phase can 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. The structured aqueous cleansing phase of the present compositions may further comprise additional ingredients such as those described hereinafter. Preferred optional ingredients for the structured aqueous cleaning phase include pigments, pH regulators, preservatives or mixtures thereof.

To the extent that any optional ingredient described herein includes specific materials described above as water structuring agents or sheet structuring agents, those materials will be considered as water structuring agents or sheet structuring agents for the purposes of present invention.

Test methods The viscosity method The viscosity of the individual phase is determined using a Brookfield DVII + Pro viscometer with a helipase auxiliary using a spindle D at 0.5 rad / sec (5 rpm). The sample is loaded into a container with a diameter greater than 6.4 cm (2.5") and is kept in equilibrium for at least 12 hours Before reading, the spindle is introduced into the sample to a depth of approximately 0.64. cm (% ") and the rotation starts and the helipaso is turned on with the regulated direction to increase the penetration of the spindle into the sample. The viscometer is prepared to read every second, and the first 10 seconds are ignored. The next 5 data points are recorded and averaged to obtain the viscosity.

Foam volume The foam volume of a personal care composition can be measured using a graduated cylinder and a rotating device. A 1000 ml graduated cylinder is selected which is marked in increments of 10 ml and having a height of 36.8 cm (14.5 inches) at the 1000 ml mark from the inner part of the base (eg, Pyrex No. 2982). Distilled water is added to the graduated cylinder (100 grams at 23 ° C). The cylinder is fixed in a rotating device that holds the cylinder with a rotation axis that cuts transversely the center of the graduated cylinder. One gram of the total composition for personal care is added into the graduated cylinder and capped. The cylinder is rotated at a speed of 3.1 rad / s (10 revolutions in approximately 20 seconds) and stopped in a vertical position to complete the first rotation sequence. A chronometer is set to 30 seconds, which allows the foam to be emptied. After 30 seconds of this drainage, the first volume of foam is measured at the nearest 10 ml mark by recording the height of the foam in ml to the base (including any water that has drained to the bottom, on which it floats). the foam). If the upper surface of the foam is uneven, the lowest height at which it is possible to see through the middle of the graduated cylinder, is the first volume of foam (ml). If the foam is so rough that only one or a few foam cells ("bubbles") reach through the entire cylinder, the height at which at least 10 foam cells are required to fill the space is the first volume of foam , also in ml up from the base. Foam cells greater than 2.5 cm (one inch) in any dimension, no matter where they occur, are designated as unfilled air instead of foam. The foam that is collected in the upper part of the cylinder Graduated but not draining, it is also incorporated in the measurement if the foam in the upper part is in a continuous layer, adding the ml of foam collected there, using a ruler to measure the thickness of the layer, to the measured ml of foam from the base. The maximum height of the foam is 1000 ml (even if the total height of the foam exceeds the 1000 ml mark on the graduated cylinder). One minute after finishing the first rotation, a second rotation sequence is started which is identical in speed and duration to the first rotation sequence. The second volume of foam is recorded in the same way as the first, after the same 30 seconds of drainage time. A third sequence is completed and the third volume of foam is measured in the same way, with the same pause between each drain and taking the measurement. The resulting foam after each sequence is added together and the total volume of the foam is determined as the sum of the three measurements, in ml. The instantaneous volume of foam is the result of the first rotation sequence only, in ml, ie the first volume of foam. For cleaning applications, the personal care compositions can produce a total foam volume of at least about 300 ml or greater than about 600 ml as described in the foaming volume test. The personal care compositions can produce an instantaneous foam volume of at least about 100 ml, greater than about 200 ml, or greater than about 300 ml as described in the foam volume test.
