Embodiment 1-2 and comparative example 1-2

[0302] [preparation]

[0303] The cosmetic compositions for hair coloring according to Examples 1-2 (Ex. 1 and Ex. 2) and Comparative Examples 1-2 (Comp. Ex. 1 and Comp. Ex. 2) were each expressed by mixing at room temperature 1 and pour it into a transparent container with the same volume. The numerical values ​​of the amounts of ingredients are all based on "% by weight" as the active raw material.

[0304] [Evaluation of color difference]

[0305] Each composition according to Examples 1-2 and Comparative Examples 1-2 was applied uniformly to 1 gram of a lock of 100% white natural human hair. The tresses were then left to stand at 40° C. for 15 minutes, followed by washing with water, shampooing, rinsing once and drying the tresses. Minolta CM-580 was used to evaluate the color difference of the tresses before and after the above-mentioned dyeing process. The ΔE* (between the color of the undyed original tress and the color of the dyed tress) was calculated based on CIE...

Abstract

The present invention relates to a composition for dyeing keratin fibers, comprising (a) at least one direct dye; and (b) at least one oxygen-containing polycyclic compound which has at least one oxygen-containing polycyclic ring. The composition according to the present invention may further include (c) at least one specific sulfone compound. The composition according to the present invention isa one-part composition and can prevent or reduce skin staining by the direct dye on the skin such as the scalp, while providing the keratin fibers with good cosmetic effects such as good coloring properties.

Description

technical field [0001] The present invention relates to a composition for dyeing keratin fibers, in particular with at least one direct dye, and to a method of using the same. Background technique [0002] It is known to dye angles with coloring compositions containing oxidative coloring precursors (commonly referred to as oxidative bases, such as o- or p-phenylenediamines, o- or p-aminophenols and heterocyclic compounds). Protein fibers, especially human hair dyed. These oxidation bases are usually combined with couplers. These color bases and these couplers are colorless or weakly colored compounds which, when combined with oxidative products, can give colored compounds via oxidative condensation processes. [0003] This type of coloration by oxidation enables the achievement of colors with great visibility, gray coverage and a wide range of shades, but it suffers from the use of oxidizing and alkaline ) and cause damage to keratin fibers. [0004] On the other hand, i...
