Description

Technical Field

[0001] The present invention relates to a composition for keratin fibers, and more particularly to a composition for decolorizing or coloring keratin fibers such as hair.

Background Art

[0002] It is known to dye keratin fibers, in particular hair, using dyeing compositions containing oxidation bases, commonly referred to as oxidation coloring precursors, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds. These oxidation bases are generally combined with couplers. These oxidation bases and couplers are colorless or weakly colored compounds. However, when combined with an oxidizing agent, they can impart colored dye molecules through an oxidative condensation process.

[0003] This type of coloring by oxidation, i.e., oxidative dyeing, allows for very high visibility, coverage of white hair, and obtaining colors with a variety of shades. Oxidative dyeing is widely used because it has a higher color uptake compared to so-called direct dyeing using direct dyes.

[0004] To carry out oxidative dyeing, typically a composition containing an oxidation base and a coupler together with an alkaline agent is mixed with a developer composition containing an oxidizing agent to prepare a ready-to-use composition, which is then applied onto the keratin fibers to dye the keratin fibers.

[0005] The developer composition can decolorize keratin fibers due to the function of the oxidizing agent in the composition. Therefore, the developer composition and the ready-to-use composition (which may contain no oxidation base at all, with or without any coupler) can be used to decolorize keratin fibers.

[0229] (Examples 1 - 12 and Comparative Examples 1 - 5) The following compositions according to Examples 1 - 12 and Comparative Examples 1 - 5 shown in Tables 1 and 2 were prepared by mixing the components shown in Tables 1 and 2. All numerical values for the amounts of the components shown in Tables 1 and 2 are based on "mass %" of the raw materials.

[0230]

Table 1

[0231]

Table 2

[0232] [Evaluation] (Softness and Smoothness) Each of the compositions according to Examples 1 - 12 and Comparative Examples 1 - 5 was mixed with a hair dye composition (L’Oreal iNOA Japan 8.11). The mixing mass ratio of each of the compositions according to Examples 1 - 12 and Comparative Examples 1 - 5 to the hair dye composition was set to 1:1.

[0233] 8 g of each of the mixtures thus obtained was applied to 2.7 g (27 cm) of a natural Chinese hair specimen. The hair specimen was left at 25°C for 35 minutes. Subsequently, the hair specimen was washed with water, then shampooed, rinsed, and dried.

[0234] Next, the softness and smoothness of the hair specimen were evaluated by five evaluators visually scoring the hair specimen according to the following evaluation criteria. Excellent: +++ Good: ++ Average: + Poor: -

[0235] The scores were averaged. The results are shown in Tables 1 and 2.

The compositions according to Examples 1 to 12 can dye keratin fibers while improving the feel of the dyed keratin fibers, provided that the amount of the (c) branched hydrocarbon compound is 0.1% by mass or more based on the total mass of the composition.

[0237] The comparison between Examples 5 and 6 and Example 7 in Table 1 shows that the use of a plurality of hydrogenated polyisobutenes having different molecular weights or degrees of polymerization (the difference in molecular weight or degree of polymerization causes a difference in kinematic viscosity) can result in better smoothness.

[0238] The composition according to Comparative Example 1 that does not contain component (c) and the composition according to Comparative Example 2 that contains component (c) in an amount less than 0.1% by mass based on the total mass of the composition could not provide the cosmetic performance as provided by the compositions according to Examples 1 to 12.

[0239] The compositions according to Comparative Examples 3 to 5 that contain components different from component (c) could not provide any of the cosmetic performances as provided by the compositions according to Examples 1 to 12.
