    摘要： The invention relates to a method for removing horn substances from animal skin. Said method is characterised in that animal skins are treated in an aqueous bath containing between 0.05 and 5 wt. %—in relation to the weight of the salt—of at least one compound of general formula I or the corresponding alkali metallic salts or alkaline-earth metallic salts thereof or ammonium or phosphonium salts, the variables having the following definitions: R1 is selected from hydrogen or C1-C12 alkyl, unsubstituted or substituted by at least one S—H group or one O—H group; X1 to X4 are the same or different and selected from hydrogen, C1-C4 alkyl, O—H, S—H or N—HR2; and R2 represents hydrogen or C1-C12 alkyl or a C1-C4-alkyl-C═O group, at least one X1 to X4 representing S—H. If R1 contains neither O—H nor S—H, at least one other X1 to X4 is selected from S—H, OH or NH—R2. Said aqueous bath also comprises at least one compound which catalyses the hydrolysis of peptide compounds.

    摘要： Horny substances are removed from animal hides by a process wherein animal hides are treated in a liquor comprising from 0.05 to 5% by weight, based on the salted weight, of one or more compounds of the formula I or the corresponding alkali metal or alkaline earth metal or ammonium or phosphonium salts thereof, the variables being defined as follows: R1 is selected from hydrogen and C1-C12-alkyl, unsubstituted or substituted by one or more S—H or O—H groups; X1 to X4 are identical or different and are selected from hydrogen, C1-C4-alkyl, O—H, S—H and N—HR2, R2 is hydrogen or C1-C12-alkyl or a C1-C4-alkyl-C═O group, at least one of the radicals X1 to X4 being S—H, and, if R1 contains neither O—H nor S—H, at least one further radical from among X1 to X4 is selected from S—H, OH and NH—R2, and furthermore with at least one compound which catalyzes the hydrolysis of peptide bonds.
