Abstract
A method of thinning a fabric conditioning composition comprising (a) from 7.5 to 80% 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; comprises the step of adding a fatty complexing agent (b) to the composition in an amount such that the weight ratio of the mono-ester linked component of compound (a) to fatty complexing agent (b) is from 2.93:1 to 1:5.
