This invention refers to a composition for permanent waving of human hair, containing thioglycolic acid or the salts thereof, preferably the ammonium salt, and comprising two compositions which are kept separate until application, whereof a Composition (A) contains at least an amino acid hydrochloride and at least one polyol or the methyl and ethyl ethers thereof, preferably 1,2-propanediol in aqueous solution, having a pH-value of preferably between about 4.5 and 6.5, and a Composition (B) which is kept separate from said Composition (A) until use contains ammonium carbonate, ammonium hydrogen carbonate, and (or) ammonium carbamate as alkalizing agent(s), having a pH-value between about 8 and 9.5, and both compositions are mixed before application whereby a pH-value between about 7 and 8 is obtained. The compositions, which are kept separate, present outstanding stability; upon application after admixture optimal waving performance and, at the same time, gentle treatment of the hair is achieved.

Composition for permanent waving of human hair

A new multi-step process for dyeing human hair achieving improved coverage and gentle treatment of the hair and, in addition, allowing the production of numerous hair dye shades using a relatively small number of hair dye compositions, which process consists of the following steps: a) Application of an alkaline oxidation hair dye composition comprising at least one developing substance and at least one coupling substance as well as an oxidizing agent mainly onto that part of the human hair which is next to the scalp, whereby the mixture is adjusted to the hair shade desired for the total dyeing result; b) rinsing and shampooing of the hair after completed processing of the dyeing composition; c) application of an acidic oxidation hair dye composition comprising at least one developing and at least one coupling agent as well as an oxidizing agent, to the total hair, and d) rinsing of the hair after complete processing of the hair dye.

Process for oxidative dyeing and re-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

A mild permanent waving process for human hair including the steps of applying a reducing composition containing at least one thio compound, subsequently pre-fixing with a composition containing at least one dithio compound without previous rinsing, and finally fixing with a composition containing an oxidant, especially hydrogen peroxide, in a low concentration.

Process for permanent waving of human hair

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.

Hair dye composition and its application method

Agent for the long-lasting shaping of hair, on the basis of a thioglycolic acid ester as reducing agent, preferably of a glycerol monothioglycolic acid ester. The permanent shaping agent contains, in addition to the thioglycolic acid ester, an amount of 2-mercaptopropionic acid monoglycerol ester and/or 3-mercaptopropionic acid monoglycerol ester as shaping agent, and at least one solubilizer.

The permanent shaping agent containing one or more hair keratin-reducing active substances is adjusted by means of stiffening additives to a consistency that is viscous to cream-like at room temperature with a viscosity of over 100 mPa.times.s. The stiffening additives are selected such that the permanent shaping agent, upon warming to a temperature with a temperature range between 25.degree. and 42.degree. C., undergoes a decided loss of viscosity of over 60% with respect to the initial viscosity, to a value under 50 mPa.times.s, i.e., becomes fluid within this temperature range. The permanent shaping agent of raised viscous or creamy consistency is applied to curled hair on curlers and then the viscosity of the permanent shaping agent is lowered, by elevating its temperature in situ, so that the liquified agent penetrates into the hair on the curlers.

Process and means for oxidized dyeing of hair using a manganese dioxide

A set of apparatus for preparing cosmetic multi-component preparations from at least two preparation components of which at least one is liquid and the other in paste or liquid form, having a pump which can be inserted into the dispensing orifice of a first supply container containing the liquid first preparation component, the suction connection thereof being immersed in the preparation component contained in the supply container and its discharge connection being so formed that it can be sealingly connected to a self-closing bottom valve of a mixing container serving for receiving and mixing of the multi-component preparation. A pressure container is provided, in which a second supply container is disposed which is volume-variable, is filled with the additional paste or liquid preparation component and is connected to an external dispensing valve. The space remaining between the second supply container and the inside walls of the pressure container is filled with a propellant under pressure. The dispensing valve can be sealingly connected to the bottom valve of the mixing container.
