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 fabric conditioning composition comprises from 7.5 to 80% by weight of a ester-linked quaternary ammonium fabric softening material comprising at lease one mono-ester linked component and at least one tri-ester linked component, from 0.01 to 10% by weight of a nonionic surfactant and greater than 1.5 to 15% by weight of a fatty complexing agent wherein the weight ratio of the mono-ester component of compound (a) to fatty completing agent (c) is from 5:1 to 1:5. The compositions have good viscosity profiles.

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.

An aqueous, liquid fabric conditioning composition and a method for making such a composition are provided where the composition comprises a quaternary ammonium cationic softening compound and a non-ionic surfactant, where the composition comprises an emulsion in which 80% or more by weight of the droplets in the emulsion have a mean diameter of from 0.4 to 60 microns, as measured using a Malvern particle size analyser with a 45 mm lens for D[0,1] measurements and both a 45 mm and a 1000 mm lens for D[0,9] measurements. Use of a nonionic surfactant to improve the dispersibility in water of an aqueous, liquid fabric conditioning composition is also provided.

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.
