Description

compositions, methods and kits for modifying hair color

The present disclosure relates to compositions for modifying hair color including a hair color base, compositions for modifying hair color, and kits and methods for modifying hair color.

CONTEXT

Modifying or enhancing the appearance of hair is very popular among consumers, including for example changing hair color and/or imparting various properties, for example shine and conditioning of hair. In addition, consumers often want to deposit color on the hair in order to color or hide gray hair, for example on the head, facial hair, etc. Hair coloring typically involves bleaching, lightening and/or changing hair color through oxidative tints, direct tints and/or pigments providing a different shade or color and/or enhancing hair color .

Hair lightening, or hair color enhancement, processes generally require the use of compositions that include at least one oxidizing agent to lighten dark hair color to lighter shades. When colorants or tint compounds such as oxidation tint precursors and/or direct tints are present in these compositions, the compositions may change or deposit color while lightening hair color at the same time. Conventional hair color products are permanent tint compositions comprising oxidation tint precursors, also known as primary intermediates or couplers. These oxidation dye precursors are colorless or weakly colored compounds which, when combined with oxidizing agents, give rise to colored complexes through a process of oxidative condensation.

The change in pitch before and after application of a hair color modifying composition is typically evaluated when lightening or enhancing hair color. The degree or level of lightening or enhancement is determined by the variation. The term "tone" refers to the "finish" of a hue, including its degree of warmth or coolness, and is based on the classification of natural hues, a tone separating each hue from the hue that immediately follows or precedes it . Tone heights or levels typically range from 1 (black) to 10 (light blonde), with one unit generally corresponding to one tone. Accordingly, the higher the number of tones, the lighter the shade and the greater the degree of enhancement.

Hair dyeing or color enhancing compositions may require one or more alkalizing agents, such as ammonia and/or ammonium compounds, which cause the hair shaft to swell, thereby allowing small molecules to of oxidative tint to penetrate the cuticle and cortex before the oxidative condensation process is completed. The larger color complexes resulting from the oxidation reaction are then trapped inside the hair fiber, thus permanently changing the color of the hair. Although these dye and/or color enhancing compositions can effectively change hair color, they can damage hair fibers and/or irritate the scalp due to excessively high alkalinity levels.

Additionally, as consumers have become more aware of the potential risks associated with the use of certain chemicals, the demand for cosmetic products, including hair coloring or dyeing compositions, that do not use certain ingredients, has increased. .

The use of new and additional ingredients and novel combinations of ingredients is a subject of continual research in an attempt to mitigate or avoid hair damage and/or scalp or skin irritation, as well as as to provide hair color enhancing and/or dyeing compositions which do not include, or minimize/limit the use of mineral oil, certain alkalizing compounds such as ammonia and/or compounds based on ammonium, and/or certain tints such as resorcinol and/or resorcinol derivatives, while achieving the desired safety and performance objectives. However, the choice of ingredients or combinations of ingredients frequently poses difficulties as they may impair the effectiveness of the composition in depositing color or enhancing hair color, or other cosmetic attributes. Ingredient combinations should be considered for attributes such as ease and uniformity of application, rheology or viscosity properties, stability of compositions, color durability and/or color formation. target shade, while weighing potential downsides such as increased damage and/or less healthy appearance of hair.

Thus, an objective of the present disclosure is to provide new compositions for modifying hair color which offer consumers desired properties such as ease and uniformity of application, rheology or viscosity properties, stability of the compositions, durability of the color and/or formation of the target shade.

Once the mixtures in Table 6 were prepared, each mixture was applied to four different strands of dark blonde hair at a rate of 3 grams of mixture per 1 gram of hair, to determine the effectiveness of color deposition and coverage. for each mixture. After a period of exposure, the locks were rinsed, shampooed, rinsed again and dried. Once dry, the highlights were evaluated for color deposition and coverage.

As can be seen in Figures 1A and 1B, the color deposition and coverage provided by each of the inventive mixtures was comparable to that observed by the comparative mixture, although the comparative mixture had a large amount of mineral oil and a solvent system different from inventive mixtures.

This example demonstrates that, surprisingly and unexpectedly, it is possible to obtain satisfactory color deposition and coverage, comparable to traditional hair color modification compositions.

Example 7 - Assessment of the correspondence of nuances

Once the mixtures in Table 7 were prepared, each mixture was applied to strands of hair at a rate of 3 grams of mixture per 1 gram of hair, in order to verify the ability of each of the inventive compositions to correspond to the shade of each of the comparative compositions. After a period of exposure, the locks were rinsed, shampooed, rinsed again and dried. Once dry, the locks were evaluated.

As can be seen in Figures 2A to 2D, the shade obtained by each of the inventive mixtures was comparable to that of the respective comparative mixtures, although the comparative mixtures had a large amount of mineral oil, a lower amount of agent organic oxidant, and a solvent system different from the inventive mixtures.

This example demonstrates that, surprisingly and unexpectedly, the hair color modifying compositions according to the disclosure are capable of satisfactorily matching the shades obtained by traditional hair color modifying compositions.

Once the mixtures in Table 8 were prepared, each mixture was applied to three (3) different strands of hair (dark brown, dark blonde, light blonde) at a rate of 3 grams of mixture per 1 gram of hair, in order to check the capacity of each of the inventive compositions to enhance the color of the hair compared to the comparative compositions. After a period of exposure, the locks were rinsed, shampooed, rinsed again and dried. Once dry, the locks were evaluated.

As seen in Figures 3A to 3C, the enhancement obtained by each of the inventive mixtures was comparable to that of the respective comparative mixtures, although the comparative mixtures had a large amount of mineral oil and a different solvent system than that of the comparative mixtures. inventive mixtures.

This example therefore demonstrates that, surprisingly and unexpectedly, satisfactory enhancement can be obtained with the hair color modification compositions according to the disclosure, comparable to the enhancement obtained with traditional hair color modification compositions.

After an equal exposure time for each comparison, the locks were rinsed, shampooed, rinsed again and dried. Once the strands were dried, the color of each strand was evaluated. This color is considered the starting color (0) of the strands treated for this study.

Subsequently, each strand was shampooed again, rinsed, dried and the color of the strand assessed, which was repeated for a total of fifteen washes. The color difference (ΔE) of each strand was calculated after each wash according to the following equation:

in which L*, a*, and b* represent the values measured before each wash, and L ₀ *, a ₀ *, and b ₀ * represent the values measured after each wash.

As can be seen in Figures 4A to 4D, the color of the strands treated with compositions 10A to 10D had washing resistance as good (Figures 4A and 4B) or better (Figures 4C and 4D) than the color of the treated strands with compositions 10E to 10G.

The above examples demonstrate that hair color bases and hair color modifying compositions are surprisingly capable of achieving satisfactory cosmetic properties for hair, good washability, deposition and hair coverage. color, shade matching and enhancement comparable to traditional hair color modification compositions, with a viscosity that allows for effective application with minimal running or dripping.

It will be apparent to those skilled in the art that various modifications and variations can be made to the compositions and processes of the invention without departing from the spirit or scope of the invention.
