Aqueous fabric softening composition having good high temperature stability comprising a cationic fabric softening compound and water soluble polysaccharide polymers comprising hydrophobic groups selected from aryl, alkyl, alkenyl, aralkyl each having at least 14 carbon atoms and cationic quaternary ammonium salt groups such that the cationic degree of substitution is from 0.01 to 0.2, the polymers having a molecular weight in the range from 100,000 to 700,000.

Fabric softening composition

A concentrated, aqueous fabric softening composition comprises (a) an ester-linked quaternary ammonium fabric softening material comprising at least one mono-ester linked component and at least one tri-ester linked component, the material being derived from fatty groups having an iodine value of from 0 to 3 and (b) an ester-linked quaternary ammonium fabric softening material comprising at least one mono-ester linked component and at least one tri-ester linked component, the material being derived from fatty groups having an iodine value of from 20 to 140 wherein the total amount of unsaturated monoester component of material (b) is from 4 to 20% by weight of the total amount of (a) and (b).

Fabric conditioning compositions

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.

A method of preparing an aqueous, liquid fabric conditioning composition comprising (a) from about 2.5 to 80% by weight of an 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 and (c) a perfume wherein the weight ratio of the mono-ester component of compound (a) to compound (b) is from 5:1 to 1:5, wherein the method comprises the steps of the method comprising the steps of:

Method of preparing fabric conditioning compositions

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.
