Description

Title of the invention: PRODUCT FOR DYEING KERATINOUS FIBERS AND ASSOCIATED METHODS FIELD OF THE INVENTION

[0001] The present disclosure relates, in general, to personal care products, and more particularly, to products and compositions for dyeing keratinous fibers. The present disclosure further relates to a method for dyeing keratinous fibers. BACKGROUND OF THE INVENTION

[0002] The use of colorants and developers in dyeing or coloring hair is a well-known practice. Efforts to achieve a long-lasting effect, uniform color delivery, and improved color effect have resulted in the development and use of various oxidative dyes, oxidizing agents, etc. in hair dye products. Generally, in hair dyeing, the melanin pigment in keratin fibers is bleached to lighten the hair and then colored using a colorant or dye, for example, an oxidative dye. Oxidative compositions having colorants and developers, including an oxidative dye and oxidizing agents, respectively, generally need to be mixed in a bowl that can then be applied to the hair. This is often inconvenient for users because it requires prior preparation, including the provision of bowls, brushes, etc., and this is not desirable. In addition, these products with varied rheologies often pose problems in achieving optimal spreadability and uniform color delivery to the hair. Although it is desirable to achieve a creamy and uniform consistency, the use of thickeners or rheology modifiers poses a stability problem in oxidizing compositions. These stability problems can be attributed to the high reactivity of these thickeners with oxidizing agents.

[0003] Furthermore, the dye and developers are generally required to remain on the hair for a development time of about 30 to 60 minutes, for the development of the color. It is highly desirable to reduce this development time to achieve faster coloring of the hair, especially without compromising the color uptake by the keratinous fibers. The generally known compositions comprising oxidizing agents must have a development time of about 60 minutes, which makes dyeing the hair a time-consuming process. Therefore, there is a need for products that achieve improved cosmetic properties such as uniform color delivery, uniform tone, effective coloring, good revitalizing effect and a creamy consistency while having a good feel for the consumer and improving consumer comfort.

[0181] Example 2: Second composition (Composition 2)

[0182] In one example, the second composition (also referred to herein as Composition 2) was formulated using 0.06 wt% tetrasodium etidronate, 0.03 wt% sodium salicylate, 6 wt% hydrogen peroxide, 0.04 wt% tetrasodium pyrophosphate, 4.4 wt% cetearyl alcohol, 0.45 wt% beheneth-10 (behenyl alcohol polyethylene glycol ether) docosanol, 1.53 wt% by weight of ceteareth-33, 0.8% by weight of mineral oil, 0.03% by weight of ceteareth-60 myristyl glycol, and water to make up to 100% by weight.

[0185] Example 3: Evaluation of viscosity

[0186] The viscosity of composition 1 and composition 2 was evaluated in comparison with a commercially available composition (also called composition 3, shown schematically in Table 3), using the viscometer model used - pro Rheo model - R 180 with M3 spindle at 25 °C. The viscosities were measured of individual compositions, namely: Composition 1, Composition 2 and Composition 3. In addition, the viscosities of the mixtures of the compositions after mixing Composition 1 with Composition 2 or Composition 3, in a 1:1 ratio, namely: mixture of composition 1 and composition 2 (also called mixture 1); and mixture of composition 1 and composition 3 (also called mixture 2), were also measured.

[0187] Composition 3 comprises 0.06% by weight of tetrasodium etidronate, 0.03% by weight of sodium salicylate, 6% by weight of hydrogen peroxide, 0.04% by weight of tetrasodium pyrophosphate, 2.28% by weight of cetearyl alcohol, 0.85% by weight of trideceth-2 carboxamide MEA, 0.5% by weight of glycerin, 0.57% by weight of ceteareth-25 and water to make up to 100% by weight.

[0188] [Tables3] Ingredient No. (INCI) Quantity (% by weight) 1 Tetrasodium etidronate 0.06 2 Sodium salicylate 0.03 3 Hydrogen peroxide 6.0 4 Tetrasodium pyrophosphate 0.04 5 Cetearyl alcohol 2.28 6 Trideceth-2 carboxamide MEA 0.85 7 Glycerin 0.5 8 Ceteareth-25 0.57 9 Water qs 100

[0189] Results: The results of the viscosity test are shown schematically in Table 4. It was observed that the viscosity of Composition 2 was lower than that of Composition 3. The difference in viscosities of Compositions 3 and 2 was found to facilitate the improvement of the cosmetic properties and consumer convenience of the product, according to the present embodiment. It was found that the distribution of Composition 1 and Composition 3 became uneven due to the difference in viscosity, thus affecting the cosmetic properties and consumer convenience. This difference, and the improved properties, can be attributed to the carefully chosen combination of ingredients in Composition 2 in specific ranges of amounts. For example, Composition 2 includes ceteareth-33, mineral oil, ceteareth-60 myristyl glycol which are not present in Composition 3.

[0190] Furthermore, when comparing the viscosities of the combined compositions, i.e., blends 1 and 2, it was observed that blend 1 had a creamy consistency compared to that of blend 2, thus contributing to a better user feel, and an improved and uniform spreadability of the blend / product on the keratinous fibers. This also led to a difference in color delivery, as the product was intended to be applied by hand, i.e., without the need for a brush or bowl. The creamy consistency allowed the composition to be taken by hand for mixing and application to the keratinous fibers.

[0192] Example 4: Evaluation of coloring.

[0193] The coloration obtained by Mixture 1 and Mixture 2 (see Example 3) was evaluated using the L*, a*, b* system. The evaluation of the coloration can be performed visually or read on a spectrocolorimeter (such as Minolta CM3600d, illuminant D65, angle 10°, SCI values) for the colorimetric measurements of L*, a*, b*. In this L*, a*, b* system, L* represents the color intensity, a* indicates the green / red color axis, and b* indicates the blue / yellow color axis. The lower the value of L, the darker or more intense the color. The higher the value of a*, the redder the shade; the higher the value of b*, the more yellow the shade. The variation in coloration between the colored strands of natural white hair that are not treated (control) and after treatment or coloration is defined by AE*, corresponding to the color uptake on the keratinous fibers, according to the following equation:

[0194] In this equation, L*, a* and b* represent the values ​​measured after coloring of natural hair comprising 90% white hair and Lo*, a0* and b0* represent the values ​​measured for untreated natural hair comprising 90% hair.

[0195] The higher the Ade E value, the greater the difference in color between the control strands and the dyed strands and the greater the color uptake.

[0196] Results: The results of the coloring test are shown schematically in Table 5. A clear difference on the strands with the 2 mixtures Mix 1 and Mix 2 was observed. It was found that Mix 1, with an AE of 43.99, had a better color uptake on the keratinous fibers compared to Mix 2, with an AE of 40.39. The superior color uptake was obtained by Mix 1, namely the product according to the present embodiments, in reduced pause time. In addition, the color intensity was better with Mix 1 (L* significantly smaller for the mixture 1).

[0198] The product of the present disclosure achieves better cosmetic properties in dyeing keratinous fibers. It facilitates the achievement of uniform color delivery, smoothing of keratinous fibers and a long-lasting effect while having a shorter development time. It provides even more convenience for the consumer and faster dyeing solutions while achieving effective color delivery and a good conditioning effect. The product, as disclosed herein, can be received in the hands or palm of a user and applied by hand to keratinous fibers. Furthermore, the product as disclosed herein has rheological properties that are suitable for providing uniform delivery of the product to the fibers.

[0199] The improved feel and convenience for the consumer is also attributed to the creamy consistency of the compositions or product, as it does not require the use of brushes, bowls, etc. for mixing or application. The present embodiments provide a consumer-convenient method of dyeing keratinous fibers that also allows for improved and uniform coverage by hand application.
