A particulate built synthetic organic detergent composition which includes a synthetic organic detergent which is an anionic detergent, a nonionic detergent or a mixture thereof, and a building proportion of a water soluble and/or water insoluble builder, includes a dispensing assisting proportion of a siliconate. The detergent composition described preferably also includes bentonite as a fabric softening agent. Also described is a method of making the heavy duty laundry detergent composition which includes spray drying a crutcher mix of the synthetic organic detergent(s) and the builder(s) to particles of desired size and applying to the surfaces of such particles a dispensing assisting proportion of a siliconate.

Particulate detergent containing siliconate, composition and method for

Enzyme particles are coated or at least partially coated with a salt of a lower alkyl siliconic acid and/or polymerization product(s) thereof which may be formed from such acid on storage. The coated enzyme particles are useful as components of heavy duty fabric softening laundry detergent compositions, such as those which contain bentonite to soften laundry. The coating material, which may be more simply referred to as the siliconate, assists in stabilizing the enzyme when such is incorporated in detergent compositions, helps to prevent adherence of the coated particles to container or compartment walls and can aid in controlling the foaming activity of the built synthetic organic detergents.

Siliconate-coated enzyme

Sodium perborate particles are coated or at least partially coated with a salt of a lower alkyl siliconic acid and/or polymerization product(s) thereof which may be formed from such acid on storage. The coated sodium perborate particles are useful as components of heavy duty fabric softening laundry detergent compositions, such as those which contain bentonite to soften laundry. The coating material, which may be more simply referred to as the siliconate, assists in stabilizing the sodium perborate when such is incorporated in detergent compositions, helps to prevent adherence of the coated particles to container or compartment walls and can aid in controlling the foaming activity of the built synthetic organic detergents.

Siliconate-coated sodium perborate

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 of a siliconate or similarly functioning derivative of such siliconate. In addition to tending to inhibit firm 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.

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.
