Abstract
A fabric-softening composition comprises a dispersing agent, in particular a detergent-active compound, and a sultone of from 14 to 30 carbon atoms of the structure ##STR1## in which each of R.sub.1 and R.sub.2 is H or an aliphatic hydrocarbon radical having a chain of from 1 to 27 carbon atoms, at least one of R.sub.1 and R.sub.2 has a chain of at least 10 carbon atoms, and n is 1 or 2. Fabrics are softened by treatment with such a composition in the form of a dilute aqueous dispersion.

A fabric-softening composition comprising a dispersing agent and a sultone of from 14 to 30 carbon atoms of the structure ##STR3## in which each of R.sub.1 and R.sub.2 is H or an aliphatic hydrocarbon radical having a chain of from 1 to 27 carbon atoms, at least one of R.sub.1 and R.sub.2 has a chain of at least 10 carbon atoms, and n is 1 or 2, containing from 2 to 30% by weight of sultone and from 0.2 to 200 parts of sultone being present to 1 part by weight of dispersing agent;
- where the dispersing agent includes a detergent-active compound comprising an olefin sulfonate, the composition contains 1-20 parts of detergency builder per 1 part by weight of the detergent-active compound.
