Described herein is a chemical class of odorless thiols which can serve as reducing agents. This chemical class involves thiols which can be used as reducing agents for permanent styling treatments, depilatory compositions and other applications. The odorless thiols are thiols having a heterocyclic quaternary ammonium salt in their molecule.

Odorless thiols for permanent waving, straightening and depilatory applications

Method for colouring hair comprising pretreating the hair with at least one primer composition before treating the hair with a polymeric hair colouring system.

Method for colouring hair including pretreatment

The present invention concerns an auxochrome substituent for an oxidative dye coupler. The auxochrome substituent enables ready developer reaction with the coupler to form azomethine and leuco dyes. Manipulation of the auxochrome substituent enables a bathochromic or hypsochromic shift of the light absorbance by the azomethine dye formed with the auxochrome substituted coupler.

Oxidative dye couplers with novel auxochrome substituents and azomethine dyes and leuco forms thereof

A novel class of 3-halo-1H-indol-4-amine derivatives, particularly for dyeing keratin fibers, the azomethine dyes formed from them, their uses as a coupler for dyeing keratin fibers, hair dyeing compositions comprising them, method of dyeing hair thereof, and a hair dyeing kit thereof are disclosed. The products of the oxidative coupling with hair dye primary intermediates, particularly pyrazole derivative, a p-phenylenediamine derivative, a p-aminophenol derivative, have improved fastness properties over currently used violet-blue to blue azomethine dyes.

Keratin dyeing compounds, compositions containing them, and method and use thereof

Formulation for colouring hair having at least one coloured polymer.

Hair colouration formulation

The invention relates to cationic direct dyes of the formula I (1), wherein m and n are independently from each other 0 or 1, D is an aromatic or a cationic heteroaromatic group, which are further specified, K is an aromatic or heteroaromatic group, Eand Eare independently from each other &#x2550;CH&#x2014; or &#x2550;N&#x2014;, An is an anion and a is a number from 1 to 6 and Rand Rare independently from each other and further specified. The compounds show washfastness at hair-dying. 

Cationic direct dyes

Described herein is a yellow imidazolium chromophore having a structure according to Formula V.

Stable yellow imidazolium compounds

Described herein is a method of dyeing the hair. The method includes applying to the hair a hair color composition including one or more direct dye compounds and rinsing the hair with water. The one or more direct dye compounds each include a blue-violet or blue chromophore, one or two permanent cations, one to four incipient cations, and one or more hydrophobic moieties. The incipient cations are pendant to the core structure and are neutral. The direct dye compounds enter the hair shaft after the hair color composition is applied to the hair. The hair color composition has a pH of from about 6 to about 11. The pH of the hair after rinsing is from about 3.5 to about 6. The rinsing of the hair causes one or more of the one to four incipient cations to change from neutral to positively charged inside of the hair shaft.

Method of coloring hair with washfast blue imidazolium direct dye compounds

Disclosed are hair color compositions comprising novel stable violet-blue to blue imidazolium azo compounds that have a simplified chromophore and high relative solubility in aqueous systems, and that are surprisingly stable under the conditions of use and storage. These compositions are useful for dyeing fibers such as hair and other keratinaceous materials. The compositions can optionally include an oxidant.

Hair color compositions comprising stable violet-blue to blue imidazolium dyes

Described herein is a hair treatment composition including one or more fluorescent compounds. The one or more fluorescent compounds each include a fluorophore, one or two permanent cations, one to four incipient cations, and one or more hydrophobic moieties. The incipient cations are pendant to the core structure and are neutral. The one or more fluorescent compounds enter the hair shaft after the hair treatment composition is applied to the hair. The hair treatment composition has a pH of from about 7 to about 11.

Acid perspiration resistant fluorescent compounds for treating hair

Described herein is a method of dyeing the hair. The method includes applying to the hair a hair color composition including one or more direct dye compounds and rinsing the hair with water.
