The present invention relates to a stable liquid composition comprising hair direct dyes in a liquid diol which is used for dyeing hair after mixing with one or more other aqueous compositions. The compositions preferably comprise an alkalizing agent.

Liquid composition comprising hair direct dyes

The present invention concerns a process for permanent shaping of human hair used both for the permanent waving of human hair with an excellent waving effect as well as for the straightening of curled hair. Accordingly, the first object of the present invention is a process for permanent shaping hair wherein an aqueous composition comprising at least one inorganic salt is applied onto hair and optionally processed up to 20 min and optionally rinsed off and subsequently a composition comprising at least one reducing agent is applied and rinsed off from hair after a processing time of 1 to 30 min and at a temperature of 20 to 45&#xb0; C. and a composition comprising at least one oxidizing agent is applied and processed for 1 to 20 min at a temperature range of 20 to 45&#xb0; C. and rinsed off from hair.

Process for permanent shaping of human hair

The present invention concerns a process for oxidative coloring keratin fibers especially human hair wherein a pretreatment is applied onto hair prior to application of oxidative coloring agent. Accordingly, present invention is a process for oxidative dyeing of keratin fibers especially human hair wherein an aqueous composition comprising at least one inorganic salt catalyzing and/or effecting the oxidative color development reaction from oxidative dye precursors is applied onto wet or dry hair and optionally rinsed off, and subsequently an aqueous composition comprising at least one oxidative dye precursor, optionally at least one coupling agent and at least one oxidizing agent is applied onto hair and after processing of 5 to 45 min with or without use of heat, preferably at a temperature range between 20 and 45&#xb0; C., rinsed off from hair.

Process for oxidative colouring keratin fibres

This invention relates to a hair dyeing composition comprising at least one anionic and at least one cationic direct acting hair dyes and showing excellent dyeing ability and excellent resistance to hair washing and environmental influences. The coloring composition of this invention are ready to use coloring composition and, therefore, do not require any mixing prior to application with additional agents such as oxidizers. According to the invention the preferred cationic dyestuffs are selected from the following structures wherein R, R, Rand Rstand for hydrogen, a CH&#x2014; or CH&#x2014; group, and Y is an anion such as chloride, bromide, methosulfate.

Composition for dyeing keratin fibres

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.

Agent for the brightening, gloss improvement and dyeing of human hair

Hair dye composition comprising at least one triaminohydroxypyrimidine and (or) diaminodihydroxypyrimidine as developing substance, and as coupling agent 3-amino-2-methylamino-6-methoxypyridine or salts thereof, on its own or in admixture with other coupling agents. Application of this composition in admixture with an oxidant onto human hair provides excellent natural-looking hair colorations.

Hair dye composition

Hair dye composition for oxidative dyeing of human or animal hair containing as developing substances alone or in admixture with other developing substances, a hydroxytriaminopyrimidine, preferably 6-OH-2,4,5-triaminopyrimidine (4-OH-2,5,6-triaminopyrimidine) or 2-OH-4,5,6-triaminopyrimidine and/or a dihydroxydiaminopyrimidine, preferably 2,6-dihydroxy-4,5-diamino-pyrimidine or 4,6-dihydroxy-2,5-diaminopyrimidine.
