The present invention relates to substituted stilbenes and dienones which exhibit unexpected dual activity, as inhibitors of NFKB and as agonists (activators) of Nrf2. In particular, these compounds show dual activity and it has been discovered that these compounds are particularly useful in the treatment of certain cosmetic applications and in rejuvenating and beautifying skin and other keratinous tissue of a subject in need. Cosmetic compositions and methods of using said compositions in combination with other components are disclosed herein.

Provided are a pigment dispersion liquid for cosmetics having excellent dispersibility for a pigment of Pigment Red 4 (C.I. 12085) and aging stability, and an aqueous liquid cosmetic using the same, which is suitable for hair dyes and the like. The pigment dispersion liquid for cosmetics contains, at least, water, a water-soluble organic solvent, a pigment of Pigment Red 4 (C.I. 12085), and a (methacryloyl ethylbetaine/acrylates) copolymer, and a ratio of the water to total solvents is 30 to 95% by mass.

A hair coloring method may include a step of applying a mixture of the following (A) and (B) in a predetermined ratio: (A) a hair coloring agent comprising at least a basic dye, a HC dye, a second amino acid, a first cationic surfactant, a thickener, an oil agent, a first pH adjusting agent, a wetting agent and at least one selected from the group consisting of thioglycolic acid, cysteine, 3-mercapto-1,2-propanediol, cysteamine, and derivatives and salts thereof, wherein the pH of the hair coloring agent is pH 3.5 or higher, and (B) a hair cosmetics comprising at least an alkaline agent, a first amino acid, higher alcohols having 12 to 22 carbon atoms, a surfactant, and a thickener. The hair coloring method may further include a step of providing a predetermined time after the application.

A hair coloring composition may include at least one selected from the group consisting of thioglycolic acid, cysteine, 3-mercapto-1,2-propanediol, cysteamine, derivatives and salts thereof, and a basic dye, a HC dye, an amino acid, cationic surfactant, thickener, oil agent, pH adjuster, and wetting agent, wherein the pH of the hair coloring agent composition is 3.5 or higher.

Composition comprising at least two anionic surfactants, a nonionic surfactant, an amphoteric surfactant, and at least one direct dye The present invention relates to a composition for the cosmetic treatment of keratin fibres, in particular of the hair, comprising at least two anionic surfactants, at least one nonionic surfactant, at least one amphoteric surfactant and at least one direct dye. The invention also relates to a cosmetic process for treating keratin fibres, especially for dyeing the hair, using such a composition, and also to a use of said composition.

A process for dyeing keratinous material, in particular human hair, comprising (a) applying an agent containing a pigment with a colored core and a silicon-containing coating, and (b) simultaneously or successively applying an agent containing an organic silicon compound with one, two or three silicon atoms.

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair, comprising the following steps: Application of an agent (a) to the keratinous material, wherein the agent (a) comprises: (a1) at least one organic silicon compound selected from the group of silanes having one, two or three silicon atoms, and (a2) at least one derivative of alkylated silanol, and application of an agent (b) to the keratinous material, wherein the agent (b) comprises: (b1) at least one sealing reagent,wherein at least one of the agents (a) and (b) further comprises at least one colorant compound selected from the group of pigments and/or direct dyes.

Also disclosed are multi-component packaging unit (kit-of-parts) for dyeing keratinous material.

The present invention is directed to a non-oxidative dyeing composition, method, and use for hair. The composition comprises certain direct dyes, fatty alcohols, surfactants, and a buffer system.

A dye for hair coloration that has a long shelf life and is excellent in heat resistance, and a method for producing the dye for hair coloration, are provided. A dye for hair coloration represented by the following general formula (1), the dye for hair coloration having a proportion of a polyatomic anion (An) or impurities derived from An of 1% by mass or less: ##STR00001##
wherein in the formula (1), D represents a cationic moiety of the dye for hair coloration; An represents a polyatomic anion; and a and b each independently represent a value of 0 to 1.

The present invention relates to a stable powder composition comprising hair direct dyes which is used for dyeing hair after mixing with one or more aqueous compositions. The composition comprises one or more direct dyes selected from HC Red 18, HC Blue 18, and HC Yellow 16, one or more alkanolamine as alkalizing agent, an organic and/or an inorganic pulverulent excipient.
