Abstract
Abstract Detergent compositions are disclosed which comprise, as a fabric softening ingredient, a fabric softening clay. The fabric softening clay is a hectorite of natural origin, having a layer change distribution such that at least 50% is in the range 0.23-0.31. The clays preferably exhibit Relative Deposition values of at least 2.5.
