Abstract
A heavy duty laundering and textile softening detergent composition, in particulate form, useful for automatic machine washing of laundry in water, especially hot water, and readily dispensable from a charging compartment of an automatic washing machine (by action of water being fed through such compartment) includes a synthetic organic detergent, a builder for such detergent and a laundry softening proportion of bentonite, with which there is present a dispensing assisting proportion, at least 0.15%, of a siliconate or similarly functioning derivative of such siliconate. In addition to inhibiting adherence to the charging compartment walls of the bentonite, which is advantageously in separately agglomerated bead form, and promoting release thereof from such walls, the siliconate also aids in controlling the foaming activity of the built synthetic organic detergent and strengthening the bentonite agglomerates. It also assists in stabilizing perfumes, dyes and bleaches, when such are present with the detergent compositions, when it is employed in coatings for particles containing such components.
