Hair dyeing composition on the basis of an oxidation dyestuff precursor reacting with peroxide, comprising at least one developing and/or coupling substance selected from the group

Composition for the dyeing of human hair

Composition of the dyeing of human hair

The invention concerns a process for the oxidative dyeing of human hair, whereby an aqueous composition having a pH-value between 7.0 and 12.0 is applied to the hair, wherein this Composition (AB) was obtained by admixture of an oxidation dyestuff precursor Composition (A), which comprises at least one developing and at least one coupling substance as well as at least one or more specific metal compounds, having an alkaline pH-value, with a hydrogen peroxide Composition (B), having a pH-value in the acidic range and comprising 0.05 & to 5.0% by weight, calculated to the total composition, of 1-hydroxyethane-1,1-diphosphonic acid and/or the alkali or ammonium salts thereof.

Process and composition for the oxidative dyeing of human hair

A process for making a hair dye preparation involving: (a) providing an aqueous surface-active fatty alcohol dispersion containing: (i) a fatty alcohol; and (ii) a surfactant; (b) providing an oil component; (c) providing a hair dye component; and (d) combining (a)-(c), at a temperature of from 18 to 25&deg; C., to form the hair dye preparation.

Method for producing hair coloring preparations with improved viscosity

A stable, aqueous hair dyeing emulsion with good Theological properties is prepared, while simultaneously substantially reducing the manufacturing time and energy consumption, comprising at least one oxidation hair dyestuff precursor, by mixing a water-in-oil emulsion, comprising 10% to 50% by weight of at least one nonionic emulsifier, 10% to 50% by weight of at least one nonionic co-emulsifier selected from the group of C -C -fatty alcohols, C -C -fatty acid mono- and dialkanolamides and/or C -C -fatty acid esters with polyvalent alcohols, 5% to 40% by weight of oleic acid, and up to 25%, in particular 20% by weight of water, each calculated to the total w/o-emulsion composition, with an aqueous phase comprising at least one water-soluble surfactant. Mixing is carried out under shear force at 15&deg; to 30&deg; C., preferably at room temperature at about 20&deg; to 25&deg;.

Process for the preparation of stable aqueous hair dyeing emulsions

A composition for the decoloration of dyed hair consists of an alkaline Composition A containing at least one reducing agent and having a pH-value between 7.5 and 12.5, and a Composition B stored separately therefrom until application, having a highly acidic pH-value of 1 to 4 and containing at least one oily or fatty substance, at least one water-soluble emulsifier and at least one perfume, being present as an emulsion. Both Compositions are admixed immediately prior to application, whereby a product with a pH-value of 2.5 to 5.0 is obtained. This product can be distributed evenly on the hair without dripping, has an agreeable smell by the perfume contained and stabilized in Composition B, and effects even decoloration of the dyed hair.

Composition and process for de-coloring dyed hair

A flowable pulverulent bleaching or dyeing composition for human hair with improved properties of use, particularly dustlessness and good miscibility with water or aqueous hydrogen peroxide solution, is obtained by addition, preferably by a melting or spraying process, of about 5% to about 30% by wt. of at least one wax compound having a melting point between about 40&deg; C. and about 130&deg; C., preferably a C,-C,-fatty acid mono- and (or) dialkanolamide, between about 40&deg; C. and about 130&deg; C. to a powder comprising at least one solid compound exerting bleaching activity upon application on human hair or at least one direct hair dye.

Composition for dyeing and bleaching of human hair and process for its preparation

Pre-emulsion and use thereof for the preparation of a hair dyeing composition as well as process for the preparation of a hair dyeing emulsion

A dustless, free-flowing powdery bleaching material for human hair which comprises a powdery composition of at least one solid peroxide compound and at least one pulverulent carrier material admixed with an oil and/or a liquid wax.

Bleaching composition for human hair and process for its production

The invention concerns a composition for brightening, gloss improvement and, optionally, dyeing of human hair, in particular of permanently waved hair, which contains 0.5 to 12% by weight hydrogen peroxide, and optionally, at least one direct-acting hair dye in an aqueous carrier, having a Brookfield viscosity of 1,000 to 10,000 mPa.s at 25.degree. C.
