Abstract (en)
[origin: WO03097880A1] Disclosed is a method for removing horn substance from skins, pelts, or furs of dead animals by treating said skins, pelts, or furs in an aqueous liquor comprising one or several compounds of general formula I or the corresponding alkaline salts, alkaline earth metal salts, ammonium salts, or phosphonium salts thereof, in which the variables are defined as follows: R<1> is selected among hydrogen or C1-C12 alkyl, which is unsubstituted or substituted with one or several S-H group/s or O-H group/s; X<1> to X<4> are identical or different, being selected among hydrogen, C1-C4 alkyl, O-H, S-H, or N-HR<2>; R<2> represents hydrogen, C1-C12 alkyl, or a C1-C4 alkyl C=O group. At least one radical X<1> to X<4> represents S-H if R<1> contains at least one sulfur atom while at least two radicals X<1> to X<4> represent S-H if R<1> contains no sulfur atom.
