Abstract
Abstract Fabric conditioning compositions contain particles of size 0.1 to 200 microns and of melting point 38° C. to 150° C. and comprising a wax-like carrier substance and a perfume. The particles are distributed throughout a composition, especially an aqueous fabric-softening composition, which contains a fabric-substantive cationic surfactant.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
85 words
A perfumed conditioning composition in the form of an aqueous dispersion and consisting essentially of: (i) from 0.1% to 10% of a fabric-substantive cationic surfactant and, in addition, (ii) from 0.1% to 20% of particles having an average particle size from 0.1 to 200 microns and a melting point of from 38° C. to 150° C., said particles comprising, by weight of the particles, (a) less than 95% and at least 25% of a carrier substance and (b) from 1% to 75% of a perfume.
Claim 2
Dependent Claim
85 words
A perfumed conditioning composition in the form of an aqueous dispersion and consisting essentially of: (i) from 0.1% to 10% of a fabric-substantive cationic surfactant and, in addition, (ii) from 0.1% to 20% of particles having an average particle size from 0.1 to 200 microns and a melting point of from 38° C. to 150° C., said particles comprising, by weight of the particles, (a) less than 95% and at least 25% of a carrier substance and (b) from 1% to 75% of a perfume.
