Abstract:
The instant disclosure generally relates to a dual component hair coloring composition for coloring mammalian or synthetic keratin fibers, the composition comprising composition A comprising a cationic polymer, pigment microparticles and an aqueous medium, and comprising composition B comprising an anionic polymer, aqueous medium and optional cross linking agent. Optionally or alternatively composition B may contain pigment particles. The cationic and anionic polymers are at least partially soluble in the medium and the pigment microparticles are dispersed therein. The hair coloring composition forms a dual layer coating upon application to keratin fibers such as hair and has a substantially permanent pigment lastingness following development (setting); minimally alters the keratin fibers, upon application; and substantially eliminates development time. Methods of using such compositions are also described herein.
Abstract:
Agent for colouring keratin-containing fibres, in particular human hair, comprising a) ascorbic acid, b) at least one oxime compound and c) at least one reactive carbonyl compound, and method of colouring hair using this agent.
Abstract:
The invention relates to core-extended perylene bisimides of formula (I) and (II), wherein R and R independently represent unsubstituted or substituted C1-C24alkyl, C1-C24cycloalkyl or C6-C10aryl and A and A independently representS-,S-S-,CH=CH-, R OOC-C(-)=C(-)-COOR ,N=N- orN(R )- or a compound selected from the group consisting of organic radicals of formulae (III), (IV), (V), (VI) and (VII), wherein R represents hydrogen, C1-C24alkyl or C1-C24cycloalkyl, and R represents unsubstituted or substituted C1-C24alkyl, C1-C24cycloalkyl, phenyl, benzyl,CO-C1-C4alkyl,CO-C6H5 or C1-C4alkyl carboxylic acid-(C1-C4alkyl)-ester and A represents a compound having formulae (III), (IV) or (V), in addition to intermediate products for the production of the compounds. The invention also relates to a method for producing said intermediate products and to a method for the production of compounds (I) and (II) as well as to their uses as colorants.
Abstract:
The disclosure relates to methods for colouring keratinous substrates using solubilised vat dyes, as well as compositions and kits suitable for carrying out the methods. The disclosure also relates to novel solubilised vat dyes. The solubilised vat dyes are leuco vat dye sulfuric esters. A method for changing the colour of a vat-dye- coloured keratinous substrate, which is also disclosed, comprises applying a composition of pH 11.0-12.0 that comprises a reducing agent.
Abstract:
The present invention relates to agents for coloring keratin fibers which comprise at least one cationic azodye of the general formula (I). (I)
Abstract:

Abstract:
The instant disclosure generally relates to a coloring composition for coloring mammalian or synthetic keratin fibers or keratinous surfaces. The composition comprising a medium, optionally pigment microparticles and at least one dye, in particular at least one peri-arylene dye dissolved in the medium. Methods of using such compositions are also described herein.
Abstract:
A method for treating hair comprising applying at least one pigment onto hair for providing the basis for colouring hair in a more reproducible and reliable manner independently from a user's initial hair colour.
Abstract:
The present invention relates to a) a non-oxidative colouring agent for keratin fibres, in particular human hair, comprising at least one dye according to formula (I) or (II), b) an oxidative colouring agent for keratin fibres, in particular human hair, which comprises at least one oxidizing agent (e.g. hydrogen peroxide), at least one oxidative dye precursor and at least one dye according to formula (I) or (II), and c) a lightening agent for keratin fibres, in particular human hair, which comprises at least one oxidizing agent (e.g. hydrogen peroxide) and at least one dye according to formula (I) or (II), with R4 being a cationic group.
