Abstract
An aqueous emulsion comprising a fatty alkyl ester of a polyhydric alcohol and a cationic surfactant provides a fabric softening composition of unexpected efficacy. In particular, the use of a sorbitan ester with a cationic surfactant provides a softening agent which deposits effectively onto fabric from an aqueous bath.
