Abstract
PURPOSE: To obtain a keratin hydrolyzate, useful as a cold waving agent for hair, and having a specific average molecular weight and a mercapto group, by reducing keratin with a mercaptan or a sulfide in an alkaline region, and hydrolyzing the reduction product with an enzyme.
CONSTITUTION: Keratin is reduced with a mercaptan, e.g. mercaptoethanol, or a sulfide, e.g. sodium sulfide, in an alkaline region, preferably pH8W11. The reduction product thus obtained is then hydrolyzed with an acidic proteolytic enzyme, e.g. pepsin, or a neutral proteolytic enzyme, e.g. bromelin, to give a keratin hydrolyzate having an average molecular weight <2,000 and a mercapto group. The hydrolyzate maintains the excellent waving effect and setting effect for a long time without doing damage to hair because of the chemical structure and peptide linkage similar to those of the hair. Therefore, the hydrolyzate is useful as the cold waving agent and a setting
