DETAILED DESCRIPTION OF THE INVENTION

[0057] Reference is being made in detail to presently preferred embodiments of the invention. Selective embodiments are provided by way of explanation of the invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made.

[0058] The present invention is a one-part shampoo based composition for cleansing and coloring hair that is substantially free, preferably totally and completely free, of anionic surfactants. In one embodiment, the composition according to the invention comprises: [0059] (a) at least one cationic dye; [0060] (b) n-methyl acyl glucamide with a carbon chain length between 8 and 20, inclusive, preferably 8 and 10; [0061] (c) an aqueous carrier; and [0062] (d) at least one stabilizer of anti-oxidant and free radical scavanger.

[0063] Optionally, other ingredients that may be added to the composition but which are not necessary for the composition, include a rheology modifying polymer, conditioning ingredients, and additional surfactants.

[0064] The color depositing shampoo composition according to the invention comprises, by weight (all the weight percents are based on the total weight of the composition): [0065] (a) 0.0005% to 3.0% cationic dye; [0066] (b) 2.5 to 30% n-methyl acyl glucamide; [0067] (c) 30 to 70% water; and [0068] (d) 0.01 to 0.5% stabilizers of anti-oxidant and free radical scavenger.

[0069] It being understood that the above described compositions are open to the inclusion of other ingredients that may alter the characteristics of the formula without rendering the system inoperative as a color depositing shampoo.

[0070] Use of a stabilizer prevents a shift in the color deposition as the product ages and is exposed to heat. The stabilizer consist of an anti-oxidant and free radical scavenger, such as, for example, tocopherol and sodium citrate.

[0071] Other active ingredients may include rheology modifiers, fragrances, chelating agents, opacifiers, conditioning ingredients and other adjuvants. Optionally, suitable amphoteric, nonionic and/or cationic surfactants may be added to the compositions of the invention as desired. Compositions of this invention may contain any other non-anionic ingredients normally used in hair shampoos. These other ingredients may include proteins, fragrances, preservatives, thickeners, conditioners, humectants, opacifiers, and/or pH adjustors.

[0072] FIG. 1 illustrates the composition for one example embodiment of the invention with the percentages representing the amount by weight compared to total weight of the composition. In FIG. 1, the n-methyl acyl glucamide has a carbon chain length of eight and ten (C8/C10). Applicant has surprisingly discovered that using a n-methyl acyl glucamide surfactant with a C8/C10 carbon chain length produces a non-ionic based surfactant shampoo with superior foaming properties when cationic dyes are incorporated to create a color depositing shampoo. As shown in FIG. 2, the foaming properties of a shampoo made from n-methyl acyl glucamide is greatest when the carbon chain length is C8/C10, and decreases as the carbon chain length increases, such as seen in the results for the C12/C14 and the C12/C18 chain length ranges. The n-methyl acyl glucamide surfactant used in the composition of an embodiment of the invention is not, however, limited to just the C8/C10 carbon chain length. The invention also includes embodiments comprising other carbon chain lengths of the n-methyl acyl glucamide surfactant in the composition. For example, an embodiment may include a combination of n-methyl acyl glucamide surfactant having carbon chain lengths C8 to C12, or C8 to C14, or C12 to C14, and others. Combinations of different carbon chain lengths ranging from C.sub.8 to C.sub.20 are possible and included in the scope of the invention. The n-methyl acyl glucamide surfactant may be one from the group consisting of capryloyl/caproyl methyl glucamide, lauroyl/myristoyl methyl glucamide, and cocoyl methyl glucamide. The dye may be at least one from the group consisting of Basic Blue 124, Basic Yellow 87, Basic Red 51, Basic Orange 31, Basic Brown 17, Basic Blue 99, HC Blue 16, HC Blue 15, Basic Violet 2, Basic Brown 16, and Basic Yellow 57.

[0073] The compositions of the invention may be made by dispersing the ingredients in water followed by the application of sufficient heat to dissolve the ingredients without causing decomposition. For example, the procedure to create the example composition identified in FIG. 1 is as follows: [0074] 1. To vessel, add water and disperse guar hydroxypropyltrimonium chloride with a prop mixer. [0075] 2. Add polyacrylate-1 cross polymer with continued mixing. [0076] 3. Add surfactants, chelator, preservatives, panthenol and protein. [0077] 4. Premix the fragrance and the phytantriol and add to main batch. [0078] 5. Adjust pH to between 4.5 and 5.0 with citric acid. Continue mixing for 45 minutes. [0079] 6. In a separate vessel, charge water and add dyes. Heat to 60 degrees Celsius and mix until dyes are dissolved. Add to main vessel and mix until uniform.

[0080] The superior color depositing and foaming properties of the shampoo according to the invention is depicted by way of a comparison with existing compositions. Applicant's color depositing shampoo according to the example embodiment in FIG. 1 (an illustration of the invention and not intended to limit same) was compared to four other shampoos that impart color to the hair and those products are described in published patent references. For purposes of the comparison, Applicant's composition is identified as Example 1 and the other compositions are identified as A, B, C and D. The compositions were all produced exactly as disclosed in the patent references, and the dye colors were replaced with the same basic cationic dye colors used in Example 1 and in equal amounts, that is 0.13% basic brown 17, 0.13% basic blue 99, and 0.2% basic red 76, for a total dye composition of 0.46% by weight.

[0081] Example 1 and all four comparative compositions (A, B, C, and D) were evaluated by the same two tests, one to measure the amount of hair color change resulting from use (the amount of dye deposition), and one to measure foaming.

[0082] For the dye deposition measurement test, bleached hair swatches supplied by International Hair Importers were used. Each swatch was dyed out with one of the compositions, the dye out procedure involved one lather of the shampoo with rinsing, followed by blow drying of the swatch. The procedure was repeated after a 21 day period on new swatches. The color was visually assessed at day 1 and at day 21 with side by side comparisons of the swatches. The amount of color change was also measured at day 1 and day 21 on the CIELAB scale using a Hunter Lab Ultra Scan XE Colormeter. FIGS. 3 and 5 include pictures of the swatches at day 1 and day 21, respectively. FIGS. 4 and 6 are line graphs showing the overall color change (E) for the swatches at day 1 and day 21, respectively.

[0083] The foaming of each shampoo was assessed by a blender test modified version of ASTM D3519-88 Foam in aqueous media (blender test). 1.0 grams of shampoo was mixed with 99.0 grams deionized water until homogeneous. The shampoo solution was put into a Bodum blender and run on high for 60 seconds. The height of the foam was measured. FIG. 7 contains a table showing the results of the foaming test.

[0084] Comparative example A is from Tamareselvy et. al. (U.S. Pat. No. 7,378,479), which discloses the combination of the cationic dyes with anionic surfactants (sodium and ammonium laureth sulfates), in combination with amphoteric surfactants (such as cocamidopropyl betaine) and cationic compatible amino-substituted vinyl polymer as a shampoo for color treatment and color maintenance. The composition for A produced and tested is set forth in FIG. 8. As shown in the results, significantly less color deposition occurred on the swatch for A compared to Applicant's Example 1.

[0085] Comparative example B is from Kapsner, et. al. (U.S. Pat. No. 6,500,413 B1) which discloses the combination of one or more cationic components in an anionic system provided the predominant anionic surfactant is an acyl glucoester. The composition for B produced and tested is set forth in FIG. 9. As shown in the results, less color deposition occurred compared to Example 1 and B produced significantly less foaming compared to Example 1.

[0086] Comparative example C is from Massoni (U.S. Pat. No. 7,578,857 B1) which discloses use of cationic dyes, amphoteric surfactants, nonionic surfactants and an anionic sarcosinate surfactant for a shampoo coloring formulation. The composition for C produced and tested is set forth in FIG. 10. As shown in the results, less color deposition occurred compared to Example 1 and C produced significantly less foaming compared to Example 1.

[0087] Comparative example D is from Schmucker-Castner et. al., (U.S. Pat. No. 7,217,752) which discloses a stable, aqueous composition containing a substantially cross linked alkali-swellable acrylate copolymer rheology modifier, a surfactant, an alkaline material and various compounds requiring suspension or stabilization. Additionally, the reference discloses a phase stable cationic dye composition. The composition for D produced and tested is set forth in FIG. 11. Although the amount of color deposition compared to Example 1 may be close, D provides significantly less foaming than Example 1.

[0088] Accordingly, none of the other compositions tested provide the same or an equivalent ability to color hair and foam.

[0089] Applicant has also surprisingly discovered that a specific combination of anti-oxidants with specific cationic dyes and fragrance can be used to create an effective and efficient fragranced, color depositing shampoo that remains stable with predictable performance within the shelf life of the product. Applicant has discovered that a color depositing shampoo that contains select cationic dyes, anti-oxidants and free radical scavengers are stable for an expected shelf life. The invention is a cleansing and coloring composition that remains stable over a commercially acceptable shelf life as predicted by accelerated stability testing. In another embodiment of the invention, said composition according to the invention comprises: [0090] (a) at least one cationic dye; [0091] (b) at least one nonionic or amphoteric surfactant; [0092] (c) an aqueous carrier; [0093] (d) a combination of stabilizers (Di-t-butyl-4-hydroxyhydrocinnamate and Tris (Tetramethylhydroxypiperidinol) Citrate; and [0094] (e) a fragrance (Givaudan UAE17135).

[0095] The color depositing shampoo composition according to the invention comprises, by weight (all the weight percents are based on the total weight of the composition): [0096] (a) 0.0005% to 3.0% cationic dye; [0097] (b) 2.5 to 30% n-methyl acyl glucamide; [0098] (c) 30 to 70% water; [0099] (d) 0.01 to 0.5% Di-t-butyl-4-hydroxyhydrocinnamate and Tris (Tetramethylhydroxypiperidinol) Citrate; and [0100] (e) 0.1 to 2.0% fragrance (Givaudan UAE17135).

[0101] It is being understood that the above-described compositions are open to the inclusion of other ingredients that may alter the characteristics of the formula without rendering the system inoperative as a color depositing shampoo. Use of an anti-oxidant as a stabilizer prevents a shift in the color as the product ages and is exposed to heat. Other ingredients may include rheology modifiers, fragrances, chelating agents, opacifiers conditioning ingredients and other adjuvants. Suitable amphoteric, nonionic and/or cationic surfactants may be added to the compositions of the invention as desired. Compositions of this invention may contain any other non-anionic ingredients normally used in hair shampoos. These ingredients may include proteins, preservatives, thickeners, conditioners, humectants and/or pH adjustors.

[0102] The compositions of the invention may be made by dispersing the ingredients in water followed by the application of sufficient heat to dissolve the ingredients without causing decomposition.

[0103] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the present invention.
