    摘要: Alkylamino-mercaptoalkylamides have the formula ##STR1## wherein A represents the divalent radical --(CH.sub.2).sub.n --, wherein n is a whole number ranging from 2 to 5, or the divalent radical --(CH.sub.2).sub.2 --O--(CH.sub.2).sub.2 --,m is 0, 1 or 2,R.sub.1 represents hydrogen or linear or branched lower alkyl having 1-5 carbon atoms,R.sub.2 and R.sub.3, each independently, represent hydrogen or a linear or branched lower alkyl having 1-4 carbon atoms with the proviso that R.sub.2 and R.sub.3 are not hydrogen simultaneously and the salts of the compound of formula I as well as the corresponding disulfides with the exclusion of the disulfide in which A=--(CH.sub.2).sub.2 --, m=0, R.sub.1 and R.sub.2 =H and R.sub.3 =--C.sub.2 H.sub.5. The compound of formula I is used as a reducing agent in a cosmetic composition for the permanent deformation of hair.

    摘要: A process for permanently reshaping hair consists of applying an amino compound, an amidothiol compound or a salt of an amino compound or an amidothiol compound as a reducing agent to open the keratin bonds of hair and reforming the bonds using an oxidizing composition or aerial oxygen, wherein prior to or simultaneously with the application of the reducing agent, at least one alkali metal, alkaline-earth metal or ammonium bromide is applied to the hair as a doping agent for the reducing agent. A composition for carrying out the process contains at least one amino compound, amidothiol compound or a salt of an amino compound or an amidothiol compound as a reducing agent, at least one alkali metal, alkaline-earth metal or ammonium bromide as a doping agent for the reducing agent, and a suitable cosmetic vehicle. This process and composition enable improved qualities to be obtained in the permanent reshaping of hair, in particular improved curling.
