The present disclosure relates to a cosmetic product for dyeing keratin fibres which contains two separate powdered preparations (A) and (B), which are each packaged in a water-soluble film, and to a method for dyeing keratin fibres using said product. The cosmetic product of the present disclosure does not require the use of free hydrogen peroxide.

The instant disclosure relates to hair coloring base compositions and developer compositions that can be incorporated into a hair color cartridge, which combines the compositions and dispenses them onto hair. The hair color cartridge includes: (a) one or more hair coloring base compositions and; (b) one or more developer compositions, which can be combined to form an active hair coloring composition and dispensed onto hair. The hair coloring base compositions typically include one or more oxidative dye precursors; one or more alkalizing agents; one or more reducing agents; optionally, one or more cationic conditioning polymers; one or more surfactants; one or more water-soluble solvents; and water. The developer compositions typically include one or more oxidizing agents; one or more surfactants; and water. The unique components and fluid characteristics of the various compositions are such that devices or appliances comprising them accurately combine and dispense the hair coloring base composition(s) with the developer composition(s) in a predetermined ratio with excellent consistency for application to hair.

An agent for dyeing keratin fibers comprises a composition A comprising at least one alkalizing agent, at least one oxidative dye precursor, at least one surfactant and at least one fatty substance free of carboxylic acid groups and a composition B comprising at least one oxidizing agent and at least one surfactant. The concentration of fatty substances free of carboxylic acid groups after mixing composition A and composition B is at least 20% by weight relative to the total weight of the mixed composition A and B. The concentration of alkalizing agent after mixing composition A and composition B is not more than 1.75% by weight relative to the total weight of the mixed composition A and B.

The object of the present disclosure is a method for dyeing human hair which is adapted to the differing degrees of damage along the length of the hair fiber and achieves more homogenous coloring results.

Agents for coloring keratinous fibers and methods of dying human hair are provided herein. In an embodiment, an agent is provided for coloring keratinous fibers. The agent is included in a cosmetic carrier and includes at least one non-ionic direct dye and at least about 0.1 wt. %in relation to the entire agentof one or several polyols.

The present invention relates to a composition for dyeing keratin fibers, in particular keratin fibers such as the hair, comprising: a) at least one oxidation base 3-(2,5-diaminophenyl)-1-propanol and/or acid salts thereof or solvates thereof such as hydrates; b) at least one coupler; c) at least 10% by weight of the total weight of the composition of a fatty substance which is preferably liquid and non-silicone-based; d) at least one nonionic surfactant chosen from alkyl(poly)glycoside surfactants, esters of oxyalkylenated sorbitan and fatty acids and oxyalkylenated fatty alcohols; e) optionally at least one basifying agent; and f) optionally at least one chemical oxidizing agent. The invention also relates to a process for dyeing keratin fibers such as the hair using the composition of the invention, and to a multi-compartment device for using the composition of the invention.

The present disclosure relates to agents for the oxidative coloring of keratinic fibers, which are characterized in hat they contain derivatives of anisole as novel developer molecules.

The present disclosure concerns a multi-component packing unit (kit of parts) for reshaping and coloring keratinous fibers, more particularly human hair, comprising at least two separately packaged preparations (A) and (B), the first preparation (A) comprising, in a cosmetic vehicle (A1), one or more resorcinol derivatives from the group consisting of resorcinol, 2-methylresorcinol and 4-chlororesorcinol, and (A2) one or more oxidation dye precursors from the group consisting of p-phenylenediamines, p-aminophenols, 2,4,5,6-tetraaminopyrimidines and 4,5-diaminopyrazoles, and the second preparation (B) comprising, in a cosmetic vehicle (B1), hydrogen peroxide, wherein the molar ratio of all resorcinol derivatives (A1) in the preparation (A) to all developer-type oxidation dyes (A2) in the preparation (A), i.e. the molar ratio (A1)/(A2), is at least about 1.2.

Disclosed herein is a compound of formula I:

##STR00001##

wherein the substituents are defined herein.

The present invention relates to a composition for dyeing keratin fibers, comprising a) at least one oxidation dye precursor, b) at least one anionic associative polymer i), c) at least one anionic non associative polymer ii), and d) at least one anionic surfactant.
