Abstract

A new plasticiser with high plasticising power was isolated from fur leather waste fleshings and trimmings of lambskins and sheepskins. The product was described as a natural fat containing 95.6% triglycerides. The composition of the triglyceride groups of differing unsaturation was established by argentation tlc and densitometry. The isolation of a new plasticiser was made with low energy consumption giving an inexpensive production process. The process is ecologically interesting due to the utilization of the rapidly decaying fur industry waste.
