Abstract

1. Process of degreasing moist raw skins received from a rendering establishment, consisting in placing the raw skins in their initial moist state within a liquid bath based on trichloro-1,1,2 trifluoro-1,2,2 ethane, during a period necessary for separation of the interstitial fats and residual superficial fats.
