Abstract

Provided is a method for removing wool or hair from at least one raw skin or hide prior to tanning, the skin or hide having a flesh side and a grain side, comprising: a) contacting the skin or hide with a composition comprising a protective agent, b) contacting the skin or hide with a composition comprising a depilatory enzyme, c) contacting the skin or hide with an activating composition, wherein the activating composition activates the depilatory enzyme in b) to act on the depilatory active structures in the skin or hide, and d) removing the wool or hair from the skin or hide. The preferred protective agents include tetrakis(hydroxymethyl)phosphine compounds (THP), tetrakis(hydroxymethyl)phosphonium salts (THP salts), tetrakis(hydroxymethyl)phosphine condensates (THP condensates) and oxazolidine. The preferred enzymes used include subtilisins and lipases.
