Abstract
A granular fabric softening composition, which can be added to water to form an aqueous concentrated emulsion, comprising nonionic fabric softener, preferably a fatty alkyl ester of a polyhydric alcohol, and a mono-long-chain alkyl cationic surfactant. In particular, the use of a sorbitan ester with a mono-long-chain alkyl cationic surfactant provides a granular softening agent which can be used to form a highly dispersed, concentrated, aqueous composition which, when added to, e.g., a rinse cycle of a typical washing process, effectively deposits onto fabric from the aqueous bath.
