The present invention relates to thickened fabric conditioners, which fabric conditioners contain a particular polymeric thickener, which is obtained by polymerizing from 5 to 100 mole percent of a cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide, and from 70 to 300 ppm of a
The present invention relates to thickened fabric conditioners, which fabric conditioners contain a particular polymeric thickener, which is obtained by polymerizing from 5 to 100 mole percent of a cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide, and from 70 to 300 ppm of a difunctional vinyl addition monomer cross-linking agent. As compared to such compositions comprising a similar product but obtained from a polymerization reaction using between 5 and 45 ppm cross-linking agent considerable advantages are obtained. Especially, the delivery of fragrance present in the softening composition is more efficiently carried over to the fabrics to be treated.
