Abstract: 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.

Abstract: 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, andd) rinsing of the hair after complete processing of the hair dye.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A mixture for the oxidative dyeing of human or animal hair, which is prepared immediately before application by mixing an oxidant and a dye base in cream, gel or powder form containing at least one oxidative dye and adjusting to a pH in the range of 8.0 to 10.5.The means contains in the freshly-prepared state a microencapsulated, acid-reacting compound in an amount which shifts the pH of the dye into the weakly alkaline (pH.ltoreq.8), neutral or acid range.The encapsulating material for the acid-reacting compound is soluble in the alkaline dye or changeable at least in its strength properties in the sense of a weakening, the wall thickness of the microcapsules being so adjusted that the walls are dissolved or weakened within a period between 10 and 60 minutes to such an extent that the acid-reacting compound is able by itself or upon the exertion of an additional mechanical stress to emerge into the dye.Furthermore, the invention relates to the use of the means for the redyeing of dyed hair.

Abstract: 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.

Abstract: In a method for the oxidative dyeing of human or animal hair a hair dyeing agenet is prepared from at least one oxidation dye in creme or gel form, which is adjusted to a pH of 5.9 to 6.9.The preparation is performed with the addition of at least one alkali metal salt or alkaline earth metal salt as catalyst, which is added simultaneously with or immediately after the mixing of the oxidation dye with the oxidizing agent, the amount added being such that it is contained in the treatment-ready hair dyeing agent in proportions between 0.0001 and 1.00 wt.-%, preferably between 0.0004 and 0.001 wt.-%.

Abstract: In a process for the oxidative dyeing of human or animal hair, a hair dyeing agent is prepared immediately before use from at least one oxidation dye and an oxidizing agent, applied to the hair to be dyed, and made to act for a given period of time, whereupon the hair dyeing agent is washed out. The hair dyeing agent that is to be used is prepared from an oxidation dye and the oxidizing agent with the concomitant use of manganese dioxide in powder form, while the finished hair dyeing agent is adjusted to a weakly acid pH in the range from 5.9 to 6.9.

Abstract: 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.
