Patent number: 4482471Abstract: 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.Type: GrantFiled: November 21, 1983Date of Patent: November 13, 1984Assignee: Colgate-Palmolive CompanyInventors: Edwin Allen, Alan Dillarstone, Joseph A.

Patent number: 4482477Abstract: 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.Type: GrantFiled: November 21, 1983Date of Patent: November 13, 1984Assignee: Colgate-Palmolive CompanyInventors: Edwin Allen, Alan Dillarstone, Joseph A.

Patent number: 4427567Abstract: Poorly flowing or caked detergent powders which include synthetic organic detergent, inorganic salt and moisture (with at least some of the moisture hydrating the salt) are reconditioned by mixing therewith a small proportion of hydratable molecular sieve zeolite, preferably of an initial moisture content of less than 3%. The reconditioned powders are free flowing, non-tacky and non-caking and the compositions resulting, rather than being less effective, have additional water softening and building properties due to the presence of the molecular sieve zeolite. Preferably, the molecular sieve zeolite employed is anhydrous and of type 4A and the detergent composition is a heavy duty non-phosphate product.Type: GrantFiled: June 18, 1981Date of Patent: January 24, 1984Assignee: Colgate-Palmolive CompanyInventor: Claude L. Benz

Patent number: 4421657Abstract: 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.Type: GrantFiled: April 8, 1982Date of Patent: December 20, 1983Assignee: Colgate-Palmolive CompanyInventors: Edwin Allen, Alan Dillarstone, Joseph A.

Patent number: 4419250Abstract: 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.Type: GrantFiled: April 8, 1982Date of Patent: December 6, 1983Assignee: Colgate-Palmolive CompanyInventors: Edwin Allen, Alan Dillarstone, Joseph A.

Patent number: 4411809Abstract: A free flowing particulate heavy duty laundry detergent containing no more than 8.7% of phosphorus (from phosphate) is comprised of sodium tripolyphosphate particles having nonionic detergent in the interior and on the surface thereof, which adheres a coating of smaller particles of ion-exchanging zeolite to the phosphate. Also within the invention is a method of making such a product by pre-mixing spray dried sodium tripolyphosphate particles and smaller zeolite particles and admixing with them, as by spraying, in liquid form, onto moving particles, a normally liquid or pasty nonionic detergent, such as a higher fatty alcohol polyethylene oxide condensation product, which penetrates the sodium tripolyphosphate particles and adheres zeolite particles to the surfaces thereof.Type: GrantFiled: September 2, 1980Date of Patent: October 25, 1983Assignee: Colgate Palmolive CompanyInventor: Harold E.
