Fabric Conditioning Compositions

1 . 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 C 5-35 alkyl or alkenyl group, R 1 represents a C 1-4 alkyl or hydroxyalkyl group or a C 2-4 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 R 1 group is independently selected from C 1-4 alkyl, hydroxyalkyl or C 2-4 alkenyl groups; and wherein each R 2 group is independently selected from C 8-28 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 R 1 group is independently selected from C 1-4 alkyl, or C 2-4 alkenyl groups; and wherein each R 2 group is independently selected from C 8-28 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 C 1 to C 15 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.

2 . A composition as claimed in claim 1 wherein, in the nonionic material, n is from 2 to 5.

3 . A composition as claimed in claim 2 wherein, in the nonionic material, n is from 2 to 4.

4 . A composition as claimed claim 1 , wherein, in the nonionic material, the total number of carbons, R+R′, is from8to15.

5 . A composition as claimed in claim 1 wherein, in the nonionic material, the total number of carbons, R+R′, is from 10 to 15.

6 . A composition as claimed in claim 1 wherein, in the nonionic material, the total number of carbons, R+R′, is from 11 to 15.

7 . The use of a nonionic material of formula:

wherein R and R′ are independently selected from C 1 to C 15 optionally substituted alkyl, alkenyl, hydroxyalkyl, and benzyl groups and the combined number of carbons in R and R′ is from 7to 16, n is from 1 to6and a is 2 or 3

in a fabric conditioning composition comprising an ester linked quaternary ammonium fabric softening material selected from:

wherein each R is independently selected from a C 5-35 alkyl or alkenyl group, R 1 represents a C 1-4 alkyl or hydroxyalkyl group or a C 2-4 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 R 1 group is independently selected from C 2-4 alkyl groups; and wherein each R 2 group is independently selected from C 8-28 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 R 1 group is independently selected from C 1-4 alkyl, or C 2-4 alkenyl groups; and wherein each R 2 group is independently selected from C 8-28 alkyl or alkenyl groups; n is 0 or an integer from 1 to 5 and T and X − are as defined above;

to improve the elevated temperature storage stability of the fabric conditioning composition.
