Abstract
Abstract The invention discloses novel sulfated silicone polymers which have the sulfate group on a pendant functionality rather than within the polymer backbone. Compounds of the invention by virtue of the presence of this anionic group, are high foaming compounds which deposit on the surface of substrates. The deposition can be enhanced by forming complexes with cationic surface active agents. These compounds alter the substrate's surface physical properties providing softness and antistatic properties, but do not exhibit defoaming properties which would minimize their applicability to detergent systems.
