Abstract
A particulate composition useful in the softening of fabrics from a wash liquor, the composition comprising a fabric softening clay material and a nonionic surfactant system which consists of one or more nonionic surfactants, wherein the nonionic surfactant system exists as a cloudy phase, at 1% concentration in water, somewhere in the range of 0.degree. C. to 80.degree. C., the weight ratio of the clay to the nonionic surfactant system is from 2:3 to 20:1, and the moisture content of the composition, as measured by the water loss at 135.degree. C., is from 7.5% to 12% by weight.
