Description

Compositions and methods FOR MODIFYING HAIR COLOR

The present disclosure relates to compositions for modifying hair color 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 improve the appearance of hair involve chemical treatment of the hair.

For example, the process of changing hair color may involve, for example, enhancing the hair color and/or 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, demi-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 usually use peroxides such as hydrogen peroxide as oxidizing agents.

On the other hand, semi-permanent or temporary hair dye compositions usually use pigments, fat-soluble dyes or direct dyes chosen from acidic (anionic), basic (cationic) or neutral direct dyes which are deposited on the hair. 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 several shampoos. 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 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 additional ingredients and new combinations of ingredients are continually being sought that can help prevent , improve or reverse damage before, during, after or in addition to hair color modification processes. 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 or viscosity properties. of the compositions, the stability of the compositions, and/or the deposition of color and the formation of a target shade, and they cannot cause further disadvantages such as increased damage or less healthy appearance of the hair.

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

Example 3 – Evaluation of the integrity of hair treated with compositions 1A-1F

The integrity of the fibers of hair treated with inventive compositions 1A-1F was evaluated by measuring the elastic modulus and tensile strength of the hair compared to hair treated with comparative compositions C1-C4.

The elastic modulus represents a measure of the spring-like structure (elasticity) of hair. The modulus of elasticity provides information about the deformation of fibers, and therefore, fibers with a higher modulus of elasticity are more resistant to deformation. As used herein, "tensile toughness" refers to a property indicating the resistance of the hair fiber to fracture when a crack or other stress concentration defect is present. To be strong, a hair fiber must be both strong and ductile. Tensile toughness is usually measured in units of Joule per cubic meter (J m ⁻³ ) in the International System of Units (SI). The higher the toughness, the higher the breaking strength.

Experiments were carried out on samples of natural hair with a length of approximately 12 cm and 50 fibers per sample. At or near the time of application, the inventive compositions 1A-1F and the comparative composition C1-C4 of Table 1 were mixed respectively with the developer D of Table 2 in a mixing ratio of approximately 1:1, which gave the corresponding mixtures, namely the hair color modifying compositions 1A+D, 1B+D, 1C+D,,, 1D+D, 1E+D, 1F+D, C1+D, C2+D, C3 +D and C4+D.

The same amount of each of the above mixtures was applied to a separate hair sample that was pre-washed with shampoo five times and air-dried. Each mixture applied to the hair was allowed to sit on the hair for approximately 35 minutes at room temperature. The hair was then rinsed under running water for approximately 30 seconds and dried with a hair dryer for 30 seconds.

The hair samples prepared as above and an untreated hair sample used as a control were allowed to equilibrate for 24 hours at 45% relative humidity and room temperature and then subjected to a tensile test. using a miniature tensile tester (MTT680 from Dia-Stron Ltd) when the hair samples were in a dry state at a tensile speed of approximately 10 mm/min when the hair samples were in a dry state. dry state. The elastic modulus and tenacity of the hair were measured. The resulting measurements were statistically analyzed using a two-sample t-test assuming equal variances, where the level of statistical significance was set at p < 0.05.

The elastic modulus results of the above treated hair samples are shown in the . As shown in the , hair treated with mixtures C2+D, C3+D or C4+D, which include only lactic acid, arginine or glycine, and hair treated with mixture C1+D, where no bonding agent is included, did not show any significant difference in terms of elastic modulus. On the other hand, hair treated with the mixture 1A+D, 1B+D, 1C+D, 1D+D, 1E+D or 1F+D, which included lactic acid and arginine and/or glycine, had a significantly higher modulus of elasticity than hair treated with the C1+D mixture. The results demonstrate that the inventive compositions, which include a synergistic combination of lactic acid and one or more amino acids such as arginine and/or glycine, significantly improved the fiber deformation resistance.

The tensile toughness results of the above treated hair samples are shown in the . As shown in the , hair treated with mixtures C2+D, C3+D or C4+D, which included only lactic acid, arginine or glycine, and hair treated with mixture C1+D, where no bonding agent is included, did not show any significant difference in terms of toughness. On the other hand, hair treated with the mixture 1A+D, 1B+D, 1C+D, 1D+D, 1E+D or 1F+D, which included lactic acid and arginine and/or glycine, had significantly higher tenacity than hair treated with the C1+D mixture. The results demonstrate that the inventive compositions, which include a synergistic combination of lactic acid and one or more amino acids such as arginine and/or glycine, significantly improved the fiber breaking strength.

Example 4 – Evaluation of the integrity of hair treated with composition 1G

The integrity of hair fibers treated with the inventive composition 1G, which comprises a binding system including lactic acid, arginine and glycerin in an amount ratio of approximately 1:3:1.5 (lactic acid: arginine: glycine) incorporated in a hair color modifying composition, was evaluated by means of a tensile test in comparison with hair treated with the comparative composition C1, where no bonding agent is included .

4.1 Hair treatment and evaluation of treated hair

Experiments were carried out on samples of natural virgin hair with a length of approximately 12 cm and 50 fibers per sample. The inventive composition 1G and the comparative composition C1 of Table 1 were respectively mixed, at or almost at the time of application, with the developer D of Table 3 in a mixing ratio of approximately 1:1 to obtain the mixtures (compositions modifying hair color) 1G+D and C1+D.

In a first test, the same amount of each of the 1G+D and C1+D mixtures above was applied to a separate hair sample which was pre-washed with shampoo five times and air-dried before application of mixtures. The bath ratio of the mixture 1G+D and C1+D respectively applied to the hair was approximately 9 g of each mixture per 3 g of hair. Each mixture applied to the hair was allowed to sit on the hair for approximately 35 minutes at room temperature. The hair was then rinsed under running water for approximately 30 seconds and dried with a hair dryer for 30 seconds.

In a second trial, the same amount of each of the above mixtures 1G+D and C1+d was applied to a separate hair sample which was pre-washed with shampoo five times and air-dried before application of mixtures. The bath ratio of the mixture 1G+D and C1+D respectively applied to the hair was approximately 9 g of each mixture per 3 g of hair. Each mixture applied to the hair was allowed to sit on the hair for approximately 35 minutes at room temperature. The mixtures applied to the hair were then rinsed and the hair samples were washed once with the shampoo. After shampooing, the treated hair was rinsed and blow-dried for 30 seconds.

The hair samples prepared as above and an untreated hair sample used as a control were allowed to equilibrate for 24 hours at 45% relative humidity and room temperature and then subjected to a tensile test. using a miniature tensile tester (MTT680 from Dia-Stron Ltd) when the hair samples were in a dry state at a tensile speed of approximately 10 mm/min. The breaking stress, plateau stress, tensile toughness and/or modulus of elasticity (Young's modulus) of the treated hair were measured. .The obtained measurements were statistically analyzed using a two-sample t-test assuming equal variances, where the level of statistical significance was set at p < 0.05.

Breaking stress represents the force/area required to break the hair fiber. Higher breaking stress represents a stronger and stiffer hair fiber. The elastic modulus represents a measure of the spring-like structure (elasticity) of hair. A higher modulus of elasticity indicates that the hair is more elastic (less brittle).

4.2 Results

The results of breaking stress, plateau stress and elastic modulus of the treated hair in the first test are shown in Figures 3-5. There illustrates the breaking stress of the treated hair, the illustrates the plateau stress of the treated hair, and the illustrates the elastic modulus of the treated hair. As shown in Figures 3, 4 and 5, hair treated with the 1G+D mixture statistically exhibited significantly higher breaking stress, plateau stress and elastic modulus (p < 0.05), which indicates that hair treated with the 1G+D mixture was not brittle and could withstand higher stresses, compared to hair treated with the C1+D mixture.

The results of elastic modulus and plateau stress of the treated hair in the second test are shown in Figures 6 and 7. As shown in and the , compared to untreated hair, hair treated with the comparative mixture C1+D showed reduced elastic modulus and plateau stress, indicating that hair treated with the mixture C1+D was damaged and exhibited altered integrity in due to chemical treatment to change hair color. In contrast, hair treated with the 1G+D mixture did not exhibit a decrease in elastic modulus compared to untreated hair and exhibited significantly improved plateau stress compared to untreated hair and hair treated with the C1+D mixture.

The above results demonstrated that the binding system in composition 1G, which includes lactic acid, arginine and glycine in a weight ratio of lactic acid to arginine and glycine of approximately 1:3:1.5, significantly improved the integrity of the hair fibers. The advantage provided by 1G composition also proved surprisingly durable. The integrity was preserved even after the treated hair was shampooed at least one more time.

Example 5 – Evaluation of the integrity of hair treated with compositions 1A and 1H

The integrity of the hair fibers treated with the inventive compositions 1A and 1H was evaluated by means of a tensile test (MTT test) in comparison with hair treated with the comparative composition C1, where no bonding agent is present. included, in the same manner as that described in Example 5 to test composition 1G. Compositions 1A and 1H include lactic acid and arginine in different amounts, with the amount of lactic acid being less than the amount of arginine.

The results obtained showed that the hair treated respectively with the 1A+D and 1H+D mixtures had a surprisingly higher elastic modulus, plateau stress and breaking stress than the hair treated with C1+D, which indicates that compositions 1A and 1H improve the integrity of the treated hair fibers. Unexpectedly, the effect also lasted after the treated hair had been shampooed at least once.

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.
