JP5816270B2 - Cosmetic composition for keratin fibers - Google Patents

Description

  The present invention relates to a cosmetic composition for keratin fibers such as hair.

  In cosmetics, oxidative compositions are used in the areas of keratin fibers, in particular human keratin fibers such as hair, which are dyed, decolored or deformed lasting for a long time.

  Thus, in hair oxidative dyeing, the oxidative composition is mixed with oxidative dyes that are themselves colorless (base and coupler) to produce colored and coloring compounds by an oxidative condensation process. . Oxidizing compositions can also be used in the direct dyeing of hair that has been colored and mixed with certain direct dyes for coloring to obtain a color that has the effect of lightening the hair. Examples of the oxidizing agent usually used for dyeing keratin fibers include compounds capable of generating hydrogen peroxide by hydrolysis of hydrogen peroxide, urea peroxide and the like. Persalts such as perborate and persulphate can also be used. More specifically, hydrogen peroxide is preferred.

  The composition containing an oxidative dye can also contain an alkaline agent (amine or ammonia). This composition is then mixed with an aqueous composition of hydrogen peroxide at the time of use.

  These compositions are also derived from anhydride products containing alkali compounds (amines and alkali silicates) and peroxidized reagents such as ammonium or alkali metal persulfates, perborates or percarbonates. It can also be formed and is diluted with an aqueous composition of hydrogen peroxide when used.

  In long-lasting deformation of hair, first, a composition containing a suitable reducing agent is used to cleave the disulfide bond -SS- of keratin (cystine) (reduction stage), and then After rinsing the treated hair, secondly, reconstituting disulfide bonds (also called oxidation stage, fixation) by applying an oxidizing composition onto the hair that was previously under tension (such as curlers), and the result And finally give the hair the desired form. This technique makes it possible to perform either waving or straightening of the hair. In contrast to the simple prior art of temporary wave formation such as water waves, the new shape imparted to the hair by the chemical treatment described above lasts for a very long time and is remarkably resistant to cleaning action with water or shampoo. Resistant.

  The oxidizing composition required for the fixed stage application is generally a composition based on hydrogen peroxide.

  The introduction of large amounts of oily compounds into the oxidizing composition for dyeing and / or decolorizing and / or permanent deformation of keratin fibers makes it possible to improve the effectiveness of the active ingredient.

  However, the introduction of large amounts of oily compounds into the oxidizing composition destabilizes the composition, which causes phase separation after a few days.

  For example, US2010158844 contains in a cosmetically acceptable medium a fatty alcohol; an oxyalkylenated fatty alcohol; an oxidizing agent; and at least 10% by weight of an oil other than a fatty alcohol relative to the total weight of the composition; A composition for the treatment of keratin fibers is described wherein the alcohol / oxyalkylenated fatty alcohol weight ratio is 5 or less. This oxidation composition does not provide overall satisfaction, especially in terms of decolorization efficacy and / or ease of use.

Decolorization or coloring, respectively, can be performed after an exposure time of about 1 to 60 minutes, after which the fibers are rinsed, optionally washed with shampoo, rinsed again and then dried, or the cosmetic composition of the present invention and Applying a cosmetic composition prepared on the spot by mixing another separate cosmetic composition containing at least one alkaline agent immediately before application to the keratin fibers to wet or dry keratin fibers The step of performing;
Leaving the cosmetic composition to act for an exposure time in the range of about 1 to 60 minutes, preferably in the range of about 5 to 45 minutes;
It is carried out by a process comprising rinsing the fiber; and optionally washing it with a shampoo, rinsing it again, and then drying it.

The cosmetic composition of the present invention is a keratin fiber permanent such as hair, for example,
Applying a cosmetic composition comprising a reducing agent such as thioglycolic acid to wet or dry keratin fibers; after an exposure time of about 5 to 40 minutes, rinsing the keratin fibers; It can be used by a process that includes the step of applying a cosmetic composition. After an exposure time of about 1 to 20 minutes, the fibers are rinsed, optionally washed with shampoo, rinsed again, and then dried.

  Application of the cosmetic composition can be realized at room temperature or using a heating device capable of generating a temperature in the range from 40 to 220 ° C, preferably in the range from 40 to 80 ° C. May be.

  The invention will be described in greater detail by way of examples, which should not be construed as limiting the scope of the invention.

(Examples 1-14 and Comparative Examples 1-6)
The following compositions according to Examples 1 to 14 and Comparative Examples 1 to 6 shown in Tables 1 to 4 (Tables 1 to 4) were prepared by mixing the components shown in Tables 1 to 4 (Tables 1 to 4). All numerical values for the amounts of ingredients shown in the table are based on "wt%" of the active material.

[Decolorization efficiency evaluation]
Each formulation of Examples 1 and 2 and Comparative Examples 1-7 was mixed with a cream having the composition shown in Table 2 in a weight ratio of 1.5: 1. 1.0 g of the resulting mixture was applied to 1.0 g of natural Japanese black hair tress for 30 minutes at 27 ° C.

The hair tress was washed with warm water and then shampooed once. After drying, use a colorimeter (Konica-Minolta: CM-508d) with ΔE (between the original and decolorized hair color under the L ^* a ^* b ^* system) And decided. For color intensity, three experiments were repeated and the results were calculated as the average of these three data.

Decolorization efficiency was also determined according to the following criteria.
ΔE
Less than 5: Low
Between 5 and 6: intermediate
More than 6: High

  The results of evaluation are shown in Table 3. As shown in Table 3, the hair tresses treated in Examples 1 and 2 showed higher depigmenting efficiency than Comparative Examples 1-7. These results indicate that Examples 1 and 2 can provide a better decolorization effect on the hair.
