摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
The invention is related to a composition for the permanent waving of human hair with improved properties of use, containing alkanediols in combination with ammonium carbamate as alkalinizing compound.
摘要:
A permanent waving composition for human hair without any skin sensitizing effect comprises as reducing agent 1,3-propanediol monothioglycollate and 1,3-propanediol dithioglycollate alone or in admixture with other reducing agents, wherein the content of 1,3-propanediol dithioglycollate is not more than 10%, preferably less than 5% by wt., calculated to the monoester.
摘要:
A composition for the permanent shaping of human hair, with good waving capability while avoiding damage to the hair, comprises at least one reducing agent and 0.1% to 15% by weight, calculated to the total composition, of 2-methyl-1.3-propanediol.
摘要:
Composition for permanent waving of human hair comprising an at least partly water-soluble chlorophyll or chlorophyll derivative, especially an alkali magnesium or copper chlorophyllin to improve the waving performance of the composition.
摘要:
