Abstract

The present invention relates to fabric cleaning and/or treatment compositions as well as methods of making and using same. Such fabric cleaning and/or treatment compositions contain species of glyceride copolymers that have the required viscosity and lubricity. Thus, such species of glyceride copolymers provide improved softening performance and formula ability.

c) each A is independently a branched hydrocarbon chain comprising from 4 to 40 carbon atoms;
d) each Y is independently selected from the group consisting of oxygen and NR 2 , wherein each R 2 is independently selected from the group consisting of hydrogen or a C 1 -C 8 alkyl;
e) M is selected from the group consisting of:
i) a C 1 -C 24 divalent linear or branched alkylene radical;
ii) —Z—X—Z—; and
iii) -(D-U—Z—X—Z—U) m -D-

wherein:
m is an integer from 1 to about 10;
each Z is independently a substituted or unsubstituted divalent C 2 -C 40 alkylene radical;
X is polysiloxane moiety;
U is —C(O)O— or —C(O)NH—; and

each D is independently a C 1 -C 24 divalent linear or branched alkylene radical.
