Abstract

A composition for permanent hair shaping comprising (i) 1 to 30 % by weight of an N-alkyl-2-mercaptoacetamide of formula (I), or the salt thereof, wherein R1 is a straight chain alkyl residue with 3 to 6 carbon atoms or a straight chain hydroxyalkyl with 3 to 6 carbon atoms, R2 and R3 are, independently from each other, hydrogen or straight chain alkyl residues with 1 to 3 carbon atoms, (ii) 0.1 to 15 % by weight of at least one alkalizing agent selected from the group consisting of lithium hydroxide, earth alkali metal hydroxides; hydroxyalkyl substituted amines with 1 to 3 alkyl residues comprising 1 to 4 carbon atom in the alkyl residue and one or two hydroxyl groups on at least one of said alkyl residues; 2,2-imino-bis-ethanoliminourea (guanidine carbonate), tetrahydro-1,4-oxazine, 2-aminoethansulfonic acid and alkaline amino acids; and (iii) 5 to 95 % by weight of water, and the method of permanently shaping hair using said composition.

Description

technical field [0001] The object of the present invention is a composition and a method for permanent styling of the hair, said composition being based on the combination of N-alkyl-2-mercaptoacetamides as keratin reducing agents and at least one specific alkalizing agent. Background technique [0002] Typical techniques for permanent hair styling are generally based on the following two treatment steps: In the first step, the cystine-disulfide bridges in the keratin of the hair are decomposed by the action of a composition comprising a reducing agent (perm composition). key to turn on. Then, set the hair into the desired shape. In a second step, the cystine-disulfide bond is closed again using a fixative, ie a composition comprising an oxidizing agent, usually hydrogen peroxide. [0003] For example thioglycolic acid in the form of its ammonium salt can be used as a typical hair keratin reducing agent, but usually causes considerable hair damage. Alkalinity-adjusted pre...
