Abstract
PURPOSE: To obtain the titled keratin readily soluble in water and aqueous solvents, by readucing a Keratinous substance to cleave sulfhydryl groups, and reacting a cationic agent having a quaternary nitrogen atom and an epoxy group with the reduction product.
CONSTITUTION: A keratinous substance, e.g. wool, feather, hair or nail, is reduced with a reducing agent, e.g. 2-mercaptoethanol, in water or its mixture with an organic solvent, e.g. methanol, acetone or dioxane, to convert disulfide bonds into sulfhydryl bonds. The resultant product is then reacted with a cationic agent, e.g. glycidyltrimethylammonium chloride, having a group of formula I, II or III and a quaternary nitrogen atom in one molecule to give the aimed modified keratinous protein. Perferably, the reducing reaction is carried out at pH 6W11 and if necessary under heating for 2W3hr.
