Abstract
Abstract Granular detergent compositions with through-the-wash fabric softening properties are prepared from conventional detergent ingredients, clay fabric softeners, and microfine particles of a complex of long-chain amine and fatty acid The amine fatty acid complex provides fabric softening performance in the compositions when fabrics washed therein are dried. Importantly, the drying operation can be simple line-drying and machine drying is not required to secure the benefits of the invention, although machine drying may be used, if desired.
