Description

Compositions and methods FOR CHANGING HAIR COLOR

The present disclosure relates to compositions for modifying hair color and methods of using the compositions to modify hair color while improving the integrity of hair fibers.

CONTEXT

It is known that consumers wish to use cosmetic and care compositions which improve 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 revitalization. Many of the compositions and methods known for improving the appearance of hair involve chemical treatment of the hair.

The process of changing hair color, for example, may involve enhancing the hair color and/or depositing an artificial color onto the hair, thereby providing a different shade or color to the hair. The process of enhancing hair color, also known as lightening, generally requires the use of compositions that include at least one oxidizing agent. Such 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.

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

On the other hand, semi-permanent or temporary hair coloring compositions typically use pigments, fat-soluble dyes, or direct dyes chosen from acidic (anionic), basic (cationic) or neutral direct dyes which are deposited on the fiber capillary 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 several times to shampoo. 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 center of the fiber.

Hair color lightening or color enhancing compositions and hair coloring compositions have an alkalinity such that these compositions have a pH value greater than 7, typically greater than or equal to 9, and may generally require the presence of ammonia or an ammonia-generating compound, or other alkalizing agents such as monoethanolamine (MEA) in sufficient quantities to make these compositions alkaline. These alkalizing agents cause the hair shaft to swell, 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 using these compositions are aggressive and can damage hair fibers and decrease hair strength, and can also negatively affect sensory properties, such as softness, shine. and the feel of the hair. Additionally, hair damaged during a bleaching and/or coloring process may not absorb color satisfactorily, resulting in unevenness or lack of color uniformity.

Thus, in order to reduce or avoid these disadvantages of products and processes for modifying hair color as described above, new and additional ingredients and new combinations of ingredients which can promote prevention, improvement or repair of damage before, during or after hair color modification processes, or in addition to these, are constantly sought. Nevertheless, 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 properties of viscosity of the compositions, stability of the compositions, and/or color deposition and formation of a target shade, and they cannot cause further disadvantages such as increased damage or less healthy appearance of the hair.

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

Examples

The following examples are intended to be non-limiting and explanatory in nature only. In the Examples, the quantities in each composition are expressed as a percentage by weight (wt%) of active materials, unless otherwise defined, relative to the total weight of the composition.

Example 1 – Basic compositions modifying hair color

Exemplary base compositions 1A-1J according to the present disclosure and comparative base compositions C1 were prepared by mixing the components according to the formulations indicated in Table 1.

The pH of each composition was approximately 10 to approximately 11. All compositions were in the form of a cream and were stable for at least 48 hours after being prepared.

Example 2 – Comparative composition of hair base comprising cationic polymers

A comparative composition of C2 hair base comprising cationic polymers such as hexadimethyrine chloride and polyquaternium-22 was prepared according to the formulation shown in Table 2.

Example 3 – Developer composition

A composition given as an example of 20 V developer D in cream, presented in Table 3, was prepared. The developer had a pH at 25C of approximately 2.2 (± 0.2).

Example 4 – Differential scanning calorimetric measurement of treated hair

The performance of compositions 1A to 1J in Table 1 was evaluated using differential scanning calorimetry, by measuring the denaturation temperature of the hair, compared to the comparative compositions C1 and C2, and to untreated control hair. The objective of using this technique was to evaluate the intensity of the binding benefit of active materials on the hair.

Differential scanning calorimetry (DSC) measures the energy transferred to or from a sample subject to physical or chemical change. It is useful for studying the structural characteristics of hair fibers. Keratin undergoes detectable transformations at different temperatures. Changes in these processing temperatures can be used to estimate the impact of a particular hair treatment on the hair. In the present case, DSC was used to measure the denaturation temperature (T _d ). The denaturation temperature (T _d ) was used as a representation of the thermal stability of hair fibers, which is influenced, at least in part, by the cross-linking density of the matrix (intermediate filament associated proteins, IFAP). The denaturation temperature (T _d ) and its relationship in determining the thermal stability of hair fibers are established in the scientific documents on the subject. Generally, hair (α-keratin protein) denaturation temperature is higher if hair strength/integrity is high and vice versa.

Experiments were carried out on strands of level 4 natural hair (NL4) with a length of approximately 12 cm and 50 fibers per strand. Before application, the hair strands were washed using shampoo five times and air dried. At or near the time of use, the inventive and comparative compositions of Table 1 and Table 2 were respectively mixed with developer D of Table 3 in a mixing ratio of approximately 1:1, resulting in corresponding mixtures, namely hair color modifying compositions of 1A+D, 1B+D, 1C+D, 1D+D, 1E+D, 1F+D, 1G+D, 1H+D, 1I+D, 1J +D, C1+D and C2+D.

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

To prepare the hair samples subjected to DSC measurement, the colored hair prepared above was cut from the central part and cut into finer particles (<0.5 mm). Hair particles (hair samples) were weighed to approximately 7 mg to 8 mg and placed in a DSC chamber. Approximately 50 μL of deionized water (DI water) was added to the tray and the hair particles were soaked in the water. For each composition, four trays were prepared (i.e. n = 4). Hair samples were equilibrated at room temperature and left overnight. The next day, approximately 24 hours after hair treatment, the hair samples were analyzed on DSC 2500 Discovery series equipment starting at 40°C and ramping from 10°C/min to 180°C.

The results of the denaturation temperature of the treated and control hair were illustrated in the graph of the . As shown in the , Compared to untreated hair, hair treated with the C2+D mixture, which contains hexadimethrin chloride and the cationic polymer polyquaternium-22, has a denaturation temperature similar to that of untreated hair. Hair treated with the C1+D mixture, which does not include any binding agent disclosed herein, or a cationic polymer, had decreased denaturation temperature, indicating that the hair was damaged or weakened due to the chemical treatment to alter hair color. hair. In contrast, hair strands treated with developer D mixtures with compositions 1A-1J all had statistically significantly improved denaturation temperatures, i.e. above 0.5°C, compared to untreated hair and hair treated with C1+D and C2+D mixtures. Additionally, hair treated with developer mixtures D and compositions 1A-1J was neither greasy nor tangled and showed a notable improvement in sensoriality and naturalness, compared to hair treated with mixture C2+D, which contains cationic polymers.

The results demonstrate that the hair color modifying compositions disclosed herein, which include a linker system comprising citric acid, an amino acid and/or an aminosulfonic acid, such as glycine, arginine and/or Taurine, when used to treat hair, has amazingly improved the strength and integrity of hair. Furthermore, the compositions according to the present disclosure do not include cationic polymers, and can therefore provide hair with better sensoriality and naturalness, compared to hair treated with a composition containing a cationic polymer.

It should be noted that the example formulations 1A-1J are transparent base compositions. They can be added to any oxidizing dye to form hair coloring compositions to add color to the hair. According to the above results, such formulated coloring compositions would not damage hair, but would improve the integrity of hair colored by these compositions.

Example 5 – Evaluation of fiber integrity by tensile test

The integrity of hair fibers treated with compositions 1A-1J, which comprise a binding agent such as citric acid, arginine, glycerin and/or taurine incorporated in a composition modifying the color of the hair hair, was evaluated by a traction test compared to hair treated with the comparative compositions C1 and C2, as well as with untreated hair.

Breaking stress represents the force/surface area required to break the hair fiber. The elastic modulus represents a measure of the elastic structure (elasticity) of the hair. The elastic modulus provides information about fiber deformation, so fibers with a higher elastic modulus are more elastic (less brittle) and resistant to deformation. As used herein, the term "tensile toughness" refers to a property indicative of the resistance of the hair fiber to fracture when a crack or other stress concentrating defect is present. To be tenacious, a hair fiber must be both resistant 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 strands of natural virgin hair with a length of approximately 12 cm and 50 fibers per strand. At or near the time of use, each of Compositions 1A-1J and Comparative Compositions C1 and C2 were respectively mixed with Developer D of Table 3 in a mixing ratio of approximately 1:1 at 27 C for approximately 35 minutes to obtain mixtures (compositions modifying hair color). To treat a 3 g lock of hair, approximately 4.5 g of each of compositions 1A-1J, C1 and C2 were mixed with approximately 4.5 g of developer D.

In an initial test, the same amount of each of the above mixtures was applied to a separate section of hair which was pre-washed with shampoo five times and air-dried before applying the mixtures, where the Bath ratio was approximately 9 g of mixture per 3 g of hair. Each mixture applied to the hair was left on the hair for approximately 35 minutes at room temperature. Then the hair was rinsed under running water for about 30 seconds and dried with a hairdryer for 30 seconds.

In a second test, the same amount of each of the above mixtures was applied to a separate section of hair which was pre-washed with shampoo five times and air-dried before applying the mixtures, where the Bath ratio is approximately 9g of mixture per 3g of hair. Each mixture applied to the hair was left on the hair for approximately 35 minutes at room temperature. Then, the mixtures applied to the hair were rinsed out and the hair strands were washed once with the shampoo. After shampooing, the treated hair strands were rinsed and blow-dried for 30 seconds.

The hair strands prepared as above and an untreated hair strand used as a control were allowed to equilibrate for 24 hours at 45% relative humidity and room temperature, then subjected to a tensile test at using a Miniature Tensile Tester (MTT680 from Dia-Stron Ltd) when the hair strands were in a dry state at a traction speed of approximately 10 mm/min. The breaking strength, 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.

The results show that compositions including a combination of citric acid and one or more amino acids such as arginine and/or glycine, and/or a sulfonic acid such as taurine, surprisingly and significantly improved resistance at breakage, the plateau stress, the tensile toughness and/or the modulus of elasticity of the treated hair, compared to the comparative compositions.

The results demonstrate the synergistic effect provided by the binding system disclosed herein.

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