ABSTRACT:
The present invention describes novel non-hydrolyzable, linear, random block copolymers comprising units of polysiloxanes and polyalkyleneoxides linked by bis-aminofunctional groups. These copolymers have been successfully applied as textile enhancers as well as conditioning agents for hair and skin care products.
