Abstract: Horny substances are removed from hides, pelts or skins of dead animals by treating the hides, pelts or skins in aqueous liquor with one or more compounds of the formula I or their corresponding alkali metal or alkaline earth metal salts or ammonium or phosphonium salts, the variables being defined as follows: R 1 is selected from hydrogen and C 1 -C 12 -alkyl, unsubstituted or substituted by one or more S-H or O-H groups; X 1 to X 4 are identical or different and are selected from hydrogen, C 1 -C 4 -alkyl, O-H, S-H and N-HR 2 , R 2 is hydrogen or C 1 -C 12 -alkyl or a C 1 -C 4 -Alkyl-C-O group, at least one radical X 1 to X 4 being S-H when R 1 contains at least one sulfur atom and at least two radicals X 1 to X 4 being S-H when R 1 contains no sulfur atom.

Abstract: Mezclas de ditiol que contienen en el rango de (A) 55 a 65 % molar de eritro-ditiol y (B) 35 a 45 % molar de treo-ditiol de la fórmula general IV y sus correspondientes sales de metales alcalinos y sales de amonio, donde R 1 es elegido de entre hidrógeno y alquilo C1-C12, no sustituido o sustituido con uno o varios grupos S-H u O- H.
