Description

Compositions and methods FOR MODIFYING HAIR COLOR

The present disclosure relates to hair color modifying compositions and methods of using the compositions to modify hair color, while at the same time strengthening the integrity of hair fibers.

CONTEXT

It is known that consumers wish to use cosmetic compositions to enhance the appearance of keratinous substrates such as hair, for example, by modifying the color, style and/or shape of the hair, and/or by imparting various properties to the hair. , such as shine and conditioning. Many of the compositions and processes known to strengthen the appearance of hair involve chemical treatment of the hair.

For example, the process of changing hair color may involve enhancing hair color by depositing an artificial color onto the hair, which provides a different shade or color to the hair. The process of hair color enhancement, also known as lightening, generally requires the use of compositions that include at least one oxidizing agent. These oxidizing agents penetrate the hair shaft and react with melanin in the hair, thereby lightening the hair color. Additional agents, such as persulfate salts, may be added to speed up the process.

A color change or color effect on the hair can be achieved using permanent, semi-permanent, semi-permanent or temporary coloring products. Conventional permanent hair color products are dye compositions comprising oxidation dye precursors, also known as intermediates or primary couplers. These oxidation dye precursors are colorless or weakly colored compounds which, when combined with oxidizing products, give rise to colored complexes through a process of oxidative condensation. Oxidizing products typically use peroxides such as hydrogen peroxide as oxidizing agents.

On the other hand, semi-permanent or temporary hair dye compositions typically use pigments, fat-soluble dyes, direct dyes chosen from acidic (anionic), basic (cationic) or neutral direct dyes which are deposited on the hair fiber. to give color to the hair. Direct dyes are non-ionic or ionic dyes and colored compounds capable of producing a more or less pronounced change in the natural color of the hair, resistant to shampooing several times. These dyes may or may not be used in the presence of an oxidizing agent. Unlike oxidation dye precursors, a direct dye is a relatively large molecule that does not easily penetrate the core of the fiber.

Hair lightening or color enhancing compositions and hair dye compositions have an alkalinity such that these compositions have a pH value greater than 7, typically 9 and above, and may generally require the presence of ammonia or dye. an ammonia gas generating compound, or other alkalizing agents such as monoethanolamine (MEA) in sufficient quantities to make these compositions alkaline. These alkalizing agents swell the hair shaft, helping to open the cuticle, allowing small oxidative dye molecules to penetrate the cuticle and cortex before the oxidative condensation process is complete. The larger color complexes resulting from the oxidative reaction are then trapped inside the hair fiber, thus permanently changing the hair color.

Although such compositions can effectively change hair color, these chemical treatments with the use of these compositions are difficult and can damage hair fibers and decrease hair strength, and can also negatively affect sensory properties, such as smoothness, shine and feel of the hair. Additionally, hair damaged during a bleaching and/or dyeing process may not absorb color satisfactorily, resulting in unevenness or non-uniformity in color.

Thus, in order to reduce or avoid these disadvantages of hair color modification products and processes as described above, new and additional ingredients and combinations of ingredients which may help prevent, improve or Reversing damage before, during, after or in addition to hair color modification processes are continuously sought after. However, the choice of ingredients or combinations of ingredients could pose difficulties as they cannot detract from other cosmetic attributes such as ease and uniformity of application, rheology properties or viscosity of the compositions, stability of the compositions, and/or color deposition and formation of a target shade, and they may not cause more disadvantages such as increased damage or less healthy appearance of the hair.

As it stands, there is therefore a need to develop new and improved products that can be used to effectively modify hair color, while maintaining or improving the integrity of the hair during coloring and avoiding or minimizing damage. caused to hair. The present disclosure addresses these concerns and needs and relates to hair color modifying compositions incorporated with binding actives to maintain and/or strengthen the integrity of chemically treated hair and/or damaged hair during hair color modification. hair.

Example 3 – Evaluation of the integrity of the treated hair fibers

The integrity of the fibers of pre-bleached hair treated with inventive compositions 1A and 1B was evaluated in comparison to pre-bleached hair treated with compositions C1-C5 and control pre-bleached hair via breaking stress tests (tensile test).

1. Preparation of treated hair

Caucasian hair braids with HT level 4-5 were used in the tests. Each braid had 50 individual fibers and was approximately 2.7 g with a length of approximately 8". The hair braids were bleached once with a standard bleaching composition for approximately 50 minutes at 33C. After bleaching , the hair braids were rinsed and washed once with standard shampoo, then blow-dried for 2 minutes. Near or at the time of use, compositions 1A, 1B and C1-C5 were mixed with the 10V D developer of Example 2 in a mixing ratio of 1:1 to prepare the hair color modifying compositions 1A+D, 1B+D, C1+D, C2+D, C3+D, C4+D and C5+D. Each resulting mixture was respectively applied to a separate pre-bleached braid in a bath ratio of 10:1 AU, then left on the hair for treatment for approximately 20 minutes, before being rinsed out. application was repeated up to seven times. Each braid was washed and blow-dried for approximately 2 minutes, or until completely dry, between applications and after the final application. The whole process was carried out at a temperature of approximately 27C on a plate in the open air (without using leaves). Each mixture was tested in duplicate on separate bleached hair braids. As a baseline control, two separate bleached braids were shampooed seven times and blow-dried for approximately 2 minutes between shampoos and after the final shampoo, without application of any hair color modifying composition.

After the first application, fourth application and/or seventh application of the mixtures, the hair braids were subjected to breaking stress tests to assess the integrity of the hair. If statistical differences are observed after the first or fourth application, additional applications may not be necessary.

Breaking stress tests

The breaking stress of the treated braids was measured using a miniature tensile testing apparatus (MTT-US1.3) at a tensile speed of approximately 10 mm/min when the hair braids were in the wet state after equilibration at room temperature and 80% relative humidity. The measured measurements of hair breakage stress after the fourth application were statistically analyzed using R software version 3.0.2, where the level of statistical significance was set at p < 0.05. The statistical results are summarized in Table 3 and illustrated on the . Breaking stress represents the force/area required to break the hair fiber. Higher breaking stress represents a stronger and stiffer hair fiber.

* CI: estimated confidence interval

**CV: coefficient of variation

As shown in Table 3 and , the process of changing the color of pre-bleached hair using compositions without bonding agents (C5+D) resulted in a significant decrease in the breakage stress value of the hair, indicating that the hair was less strong and more damaged compared to hair not treated with a color modifying composition (baseline control). On the contrary, as shown by and Table 3, hair treated with the mixtures of 1A+D or 1B+D, which include a bonding system according to the disclosure, surprisingly demonstrated a statistically significant improvement in the breaking stress value compared to hair treated with the mixture of C5+D (p < 0.05). This result demonstrates that hair treated with compositions according to the disclosure exhibited greater fiber integrity and strength, and less damage, even after being subjected to a hair color modification process, compared to hair subjected to same process but without the beneficial binding agents according to the disclosure.

The results also show that the breaking stress values of the hair treated with the mixture of C1+D, C2+D, C3+D or C4+D, which included bonding agents but not according to the disclosure, were not statistically improved, compared to the breaking stress of hair treated with the C5+D mixture (p > 0.05). This result demonstrates that hair treated with compositions according to the disclosure exhibited greater fiber integrity and strength, and less damage, even after being subjected to a hair color modification process, compared to hair subjected to same process but without the synergistic combination of binding agents according to the disclosure.

The above data demonstrated that the synergistic combination included in the claimed binding system, together with other components of an oxidative system disclosed herein, when applied to hair in the presence of an oxidizing agent, confers unexpectedly statistically improves hair integrity and minimizes additional damage to hair due to the hair color modification process.

It will be apparent to those skilled in the art that various modifications and variations can be made in the compositions and methods of the invention without departing from the spirit or scope of the disclosure. It is therefore intended that the disclosure covers these modifications and variations as well as their equivalents.
