Abstract
A fabric conditioning composition comprises (a) an ester linked quaternary ammonium fabric softening material; and (b) a nonionic material represented by formula (I) wherein R and R′ are independently selected from C1 to C15 optionally substituted alkyl, alkenyl, hydroxyalkyl and benzyl groups and the combined number of carbons in R and R′ is from 7 to 16, n is from 1 to 9 and a is 2 or 3. The nonionic material is used to improve high temperature storage stability of the composition.
Claims7
A fabric conditioning composition in the form of an aqueous dispersion comprising:
- (a) an ester-linked quaternary ammonium fabric softening material selected from
- wherein each R is independently selected from a C5-35 alkyl or alkenyl group, R1 represents a C1-4 alkyl or hydroxyalkyl group or a C2-4 alkenyl group,
- n is O or an integer selected from 1 to 4, m is 1, 2 or 3 and denotes the number of moieties to which it refers that pend directly from the N atom, and X− is an anionic group;
- wherein each R1 group is independently selected from C1-4 alkyl, hydroxyalkyl or C2-4 alkenyl groups;
- and wherein each R2 group is independently selected from C8-28 alkyl or alkenyl groups;
- n is 0 or an integer from 1 to 5 and T and X− are as defined above, and
- wherein each R1 group is independently selected from C1-4 alkyl, or C2-4 alkenyl groups;
- and wherein each R2 group is independently selected from C8-28 alkyl or alkenyl groups;
- n is 0 or an integer from 1 to 5 and T and X− are as defined above;
- (b) A nonionic material represented by formula (I):
- wherein R and R′ are independently selected from C1 to C15 optionally substituted alkyl, alkenyl, hydroxyalkyl and benzyl groups and the combined number of carbons in R and R′ is from 7 to 16, n is from 1 to 6 and a is 2 or 3.
