Fabric conditioning compositions
View Patent ↗A fabric conditioning composition comprises (a) less than 7.5% by weight of a ester-linked quaternary ammonium fabric softening material comprising at least one mono-ester linked component and at least one tri-ester linked component, and (b) a fatty complexing agent wherein the weight ratio of the mono-ester linked component of compound (a) to fatty complexing agent (b) is from 5:1 to 1:5.
1. A fabric conditioning composition comprising:
(a) less than 7.5% by weight of a ester-linked quaternary ammonium fabric softening material comprising at least one mono-ester linked component and at least one tri-ester linked component;
(b) a fatty complexing agent;
wherein the weight ratio of the mono-ester linked component of compound (a) to fatty complexing agent (b) is about 5:1 to about 1:5; and
wherein the fatty complexing agent is tallow alcohol.
2. A composition as claimed in claim 1 , wherein the quaternary ammonium material is represented by formula (I):
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,
T is
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, such as halides or alkyl sulphates, e.g. chloride, methyl sulphate or ethyl sulphate.
3. A composition as claimed in claim 1 , further comprising an oily sugar derivative.
4. A method for treatment of fabrics comprising contacting the composition as claimed in claim 1 with fabrics in a laundry treatment process.
