Description

Title of the invention: COMPOSITION FOR KERATINOUS FIBERS technical field

[0001] The present invention relates to a composition for keratinous fibers, in particular a composition for bleaching or coloring keratinous fibers such as hair. STATE OF THE ART

[0002] It is known to dye keratinous fibers, particularly hair, with dye compositions containing oxidative color precursors, generally called oxidative bases, such as ortho- or paraphenylenediamines, ortho- or para-aminophenols, and heterocyclic compounds. These oxidative bases are generally combined with couplers. These oxidative bases and couplers are colorless or weakly colored compounds. However, when combined with oxidizing agents, they can provide colored dye molecules through a process of oxidative condensation.

[0003] This type of oxidative coloring, that is, oxidative dyeing, makes it possible to obtain colors with very high visibility, gray coverage, and a wide variety of shades. Oxidative dyeing is widely used because of its strong color uptake compared to direct dyeing using so-called direct dyes.

[0004] In order to carry out an oxidative dyeing, typically, a composition comprising one or more oxidative base(s), as well as one or more coupler(s), with one or more alkaline agent(s), is mixed with a developer composition comprising one or more oxidizing agent(s) to prepare a ready-to-use composition, then the ready-to-use composition is applied to keratinous fibers to dye the keratinous fibers.

[0005] The developer composition is capable of bleaching keratin fibers due to the function of the oxidizing agent(s) in the composition. Therefore, the developer composition, as well as the ready-to-use composition (which may not include an oxidizing base with or without a coupler), can be used to bleach keratin fibers. DISCLOSURE OF THE INVENTION

[0006] Cationic polymers have been commonly used to improve the feel of hair after bleaching or coloring. However, in recent years, it has become desirable to avoid or reduce the use of cationic polymers.

[0007] Thus, an objective of the present invention is to propose a composition for keratin fibers, which can bleach or color keratin fibers while also improving the feel of bleached or colored hair, even without the aid of cationic polymers.

[0008] The above objective can be achieved by a composition for keratinous fibers, comprising: a. at least one oxidizing agent; b. at least one oil; and c. at least one branched hydrocarbon compound different from (b) oil,

[0009] in which

[0025] (1) mixing of a first composition and a second composition for prepare a mixture,

[0026] in which

[0027] the first composition comprises a. at least one oxidizing agent, b. at least one oil, and c. at least one branched hydrocarbon compound other than (b) oil

[0034] After extensive research, the inventors discovered that it is possible to propose a composition for keratinous fibers, which can bleach or color the keratinous fibers, while also improving the feel of bleached or colored hair, even without the aid of cationic polymers.

[0040] Furthermore, the composition according to the present invention can also provide good shine to keratin fibers such as hair. Thus, the composition according to the present invention can bleach or color keratin fibers, while enhancing the shine of the keratin fibers.

[0041] Furthermore, the composition according to the present invention can color or dye keratinous fibers such as hair while limiting the lightening of the keratinous fibers. In other words, the composition according to the present invention can color or dye keratinous fibers such as hair without significantly increasing the lightening of the keratinous fibers.

[0269] (Softness and Smooth Texture)

[0270] Each of the compositions, among those according to Examples 1 to 12 and Comparative Examples 1 to 5, was mixed with a dye composition (L'Oréal iNOA Japan 8.11). The mixing weight ratio between each of the compositions according to Examples 1 to 12 and Comparative Examples 1 to 5 and the dye composition was 1:1.

[0271] 8 g each of the above mixture thus obtained were applied to 2.7 g (27 cm) from a strand of natural Chinese hair. The strand of hair was left for 35 minutes at 25°C. The strand of hair was then washed with water, then shampooed, rinsed and dried.

[0272] Next, the softness and smooth texture of the hair strand were visually assessed by 5 panelists by rating the hair strand according to the following criteria.

[0273] Excellent: +++

[0274] Good: ++

[0275] Correct: +

[0276] Bad: -

[0277] The average scores were calculated. The results are shown in Tables 1 and 2.

[0278] (Summary)

[0279] Compositions according to Examples 1 to 12 which include (a) at least one oxidizing agent; (b) at least one oil; (c) at least one branched hydrocarbon compound other than (b) oil, provided that the amount of (c) branched hydrocarbon compound is 0.1% by weight or more, relative to the total weight of the composition, have been able to dye keratinous fibers, while also improving the feel of the dyed keratinous fibers.

[0280] Comparison of Examples 5 and 6 with Example 7 in Table 1 shows that using a plurality of hydrogenated polyisobutenes with a different molecular weight or degree of polymerization (the difference in molecular weight or degree of polymerization results in the difference in dynamic viscosity) can provide a better smooth texture.

[0281] The composition according to Comparative Example 1, which does not include ingredient (c), and the composition according to Comparative Example 2, which includes ingredient (c) in an amount less than 0.1% by weight, relative to the total weight of the composition, could not offer cosmetic performance as did the compositions according to Examples 1 to 12.

[0282] The compositions according to Comparative Examples 3 to 5, which include ingredients different from ingredient (c), were unable to offer cosmetic performance as did the compositions according to Examples 1 to 12.
