Abstract
The invention relates to a series of novel silicone fatty esters. This class of compounds, provide outstanding softening and lubricaton when applied to textiles and fibers. The compounds of the present invention are prepared by reacting a the terminal hydroxyl group in a silicone polymer with a fatty carboxylic acid, ester or anhydride.
