Abstract
Abstract Compositions comprising higher alkyl modified epoxy silicone terpolymers having the general formula: MD x D' y D" 2 M wherein M = R 3 SIO 1/2 D = R 2 SiO D' - E-C b H 2b Si(R)O E is either D" = R'Si(R)O R + lower alkyl of 1 to 6 carbon atoms R' - high alkyl of at least 6 carbon atoms r = 0 to 7 b= 2 to 12 x = 20 to 500 y = 4 to 15 z = 4 to 40 = preferably at least 0.01 = preferably at least 0.03 said higher alkyl modified epoxy silicones are formed into aqueous emulsions using anionic and non-ionic emulsifiers. The resulting emulsions are useful as fiber and/or textile finishes.
