Description

Title of the invention: COMPOSITION FOR DYEING / LIGHTENING KERATIN FIBERS, AND ASSOCIATED METHODS FIELD OF THE INVENTION

[0001] The present disclosure relates, generally, to personal care products and, more particularly, to compositions and methods for dyeing / lightening keratin fibers. CONTEXT OF THE INVENTION

[0002] Dyeing keratin fibers, such as human hair, permanently by oxidation dyeing is a known practice that is widely used by consumers. This dyeing technique involves applying to the keratin fibers a composition containing dye precursors, such as oxidation bases and couplers. These dye precursors are colorless or weakly colored compounds. When combined with an oxidizing agent, they give rise, by a process of oxidative condensation, to colored compounds.

[0003] Oxidation dyeing is generally carried out at an alkaline pH, which produces dyeing and, at the same time, lightening of the keratin fiber. Lightening the fiber has the advantageous effect of highlighting the color, i.e. making it more visible in the case of naturally pigmented hair. In the case of depigmented hair, it helps to provide a unified color before the dyeing effect.

[0004] In general, it is preferable to have compositions that have a dyeing and / or lightening effect that provide a uniform and deep color with a long-lasting effect. In addition, consumers increasingly prefer more sustainable compositions that have a low carbon footprint, incorporate fewer petrochemical-based compounds and are more environmentally friendly.

[0005] Thus, there is a need for a keratin fiber dyeing and / or lightening composition with which good performance can be achieved, especially in terms of dyeing and / or lightening effect, with superior color absorption, color vibrancy and durability, and which is environmentally friendly with more naturally derived ingredients.

[0273] Compositions A2 to A8 (according to the invention) and C2 to C8 (comparative) were prepared in the same manner as compositions A1 and C1, respectively, but different combinations of oxidizing bases and couplers were used instead of the combination of toluene-2,5-diamine and 2-amino-3-hydroxypyridine as shown in Table 1 above. In compositions A2 and C2, the combination of 0.96% (w / w) toluene-2,5-diamine and 0.073% (w / w) hydroxybenzomorpholine was used as oxidizing base and coupler. In compositions A3 and C3, the combination of 0.25% (w / w) N,N-bis(2-hydroxyethyl)-p-phenylenediamine sulfate and 0.073% (w / w) 2-amino-3-hydroxypyridine was used as the oxidizing base and coupler.

In compositions A8 and C8, the combination of 0.25% (w / w) N,N-bis(2-hydroxyethyl)-p-phenylenediamine sulfate and 0.72% (w / w) hydroxybenzomorpholine was used as oxidizing base and coupler.

[0274] Oxidizing composition B was prepared from the ingredients whose content is indicated in Table 2 below, expressed in % by weight:

[0275] [Table 2] Table 2 Ingredients Composition B Stabilizing and chelating agents qs Hydrogen peroxide 6.00 Cetearyl alcohol 2.28 Ceteareth-25 0.57 Trideceth-2 carboxamide MEA 0.85 Glycerol 0.50 Phosphoric acid qs pH 2.2 Water qs 100 Example 2:

[0276] Evaluation of color intensity and absorption

[0277] Protocol: Each of the compositions A1 to A8 (according to the invention) and C1 to C8 (comparative) was mixed independently with the oxidizing composition B at a weight ratio of 1:1. Each of the mixtures was applied to locks of hair containing 90% natural white hair in a proportion of 5 g of mixture per 1 g of hair.

[0278] After a 30-minute exposure time on a heating plate at 27°C, the hair was rinsed, washed and dried.

[0279] Results: Hair coloration was evaluated in the L*a*b* system, using a Konica Minolta CM-3600A spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

[0280] In this system, L* represents lightness. The smaller the value of L*, the darker and more intense the resulting coloration. Chromaticity is measured by the values ​​a* and b*, with a* representing the red / green axis and b* the yellow / blue axis.

[0281] The results for compositions Al to A8 and Cl to C8 are shown in Table 3 below:

[0282] [Table 3] Table 3 Compositions L* AL Al 29.88 Cl 34.36 A2 36.93 C2 41.16 A3 28.04 C3 30.49 A4 18.96 C4 21.7 A5 23.33 C5 26.74 A6 18.96 C6 21.11 A7 28.62 C7 32.39 A8 33.69 C8 36.01

[0283] Compositions A1 to A8 (according to the invention) had a lower L* value, with significant AL values ​​(AL > 2) and therefore exhibited better color intensity and better color absorption, compared to comparative compositions C1 to C8. BENEFITS OF THIS DISCLOSURE

[0284] The composition of the present disclosure achieves superior color performance, particularly by demonstrating more intense color with long-lasting color absorption. The composition is environmentally friendly as it incorporates natural and / or naturally derived ingredients, with a better carbon footprint and reliance on more renewable materials, thereby reducing the negative impact on the environment. In addition, the superior properties of the composition contribute to achieving smoother and more nourished hair, as well as improved shine.
