Abstract

Disclosed herein are inventive blocky cationic organopolysiloxanes and consumer product compositions comprising such organopolysiloxanes. Such compositions can deposit effectively onto target substrates to deliver consumer-desired benefits such as conditioning, anti-wrinkle, softness, and anti-static.

N is a nitrogen atom;
each R 5 is, independently, selected from the group consisting of H, C 1 -C 32 alkyl, C 1 -C 32 substituted alkyl, C 5 -C 32 aryl, C 5 -C 32 substituted aryl, C 6 -C 32 alkylaryl, C 6 -C 32 substituted alkylaryl optionally interrupted with a hetero atom selected from the group consisting of P, N, and O, C 1 -C 32 alkoxy, C 1 -C 32 substituted alkoxy, C 1 -C 32 alkylamino, and C 1 -C 32 substituted alkylamino;
each E comprises same or different divalent radicals selected from the group consisting of C 1 -C 32 alkylene, C 5 -C 32 arylene, C 5 -C 32 substituted arylene, C 6 -C 32 arylalkylene, C 6 -C 32 substituted arylalkylene, C 1 -C 32 alkoxy, C 1 -C 32 substituted alkoxy, C 1 -C 32 alkyleneamino, and C 1 -C 32 substituted alkyleneamino;
each m is an integer independently selected from 2 to 100,
each n is an integer independently selected from 1 or 2,
f is an integer from 2 to about 50,
