Abstract
A quaternary ammonium material of the formula: 1 wherein each R is independently selected from a C5-35 alkyl or alkenyl group, R1 represents a C1-4 alkyl, C2-4 alkenyl or a C1-4 hydroxyalkyl group, T is 2 n is 0 or a number selected from 1 to 4, m is 1, 2 or 3 and denotes the number of moieties to which it relates that pend directly from the N atom, and X− is an anionic group, such as halides or alkyl sulphates, has a mean particle size of from 100 to 1200 μm. The material is provided in a solid fabric conditioning composition at a level of from 1 to 45 wt % in combination with a carrier material.
Claims9
A solid fabric conditioning composition comprising:
- (a) from 1 to 45 wt % by weight of the composition of one or more cationic fabric softening agents;
- and
- (b) one or more carrier materials;
- wherein the cationic fabric softening agent comprises a quaternary ammonium material of the formula:
- 9
- wherein each R is independently selected from a C5-35 alkyl or alkenyl group, R1 represents a C1-4 alkyl, C2-4 alkenyl or a C1-4 hydroxyalkyl group,
- T is
- 10
- n is 0 or a number selected from 1 to 4, m is 1, 2 or 3 and denotes the number of moieties to which it relates that pend directly from the N atom, and X− is an anionic group, such as halides or alkyl sulphates, e.g. chloride, methyl sulphate or ethyl sulphate;
- the quaternary ammonium raw material from which the composition is prepared having a mean particle size of from 100 to 1200 μm.
