Abstract: Lightweight composite particles, primarily comprising various bentonite clays, but which may include other functional solid particles, are formed by introducing expanding gases or air into the particle forming process. The methods presented create the ability to reduce the bulk density of the composite particles while maintaining and in some cases even increasing the particle strength.

Abstract: A thickened oxidant composition is formulated to be easily and evenly applied to a vertical surface to provide consumer preferred cling to the vertical surface. The composition has a low relaxation constant. The composition is useful in cleaning toilet bowls and other hard surfaces. The composition can be applied in a stream, a spray, or an aerosol.

Abstract: The present invention is a granular colorant speckle exhibiting reduced colorant spotting, the speckle which comprises:(a) an insoluble dispersible carrier;(b) a surfactant; and(c) a substantive agent.The present invention also discloses a method for forming a colorant speckle suitable for use as a granular laundry detergent component, or a laundry additive. The speckle of the present invention is preferably produced by an agglomeration process utilizing, for example, a fluid-bed or rotary falling curtain type agglomerator.

Abstract: A dry cleaning system particularly suited for employing supercritical CO.sub.2 as the cleaning fluid consisting of a sealable cleaning vessel containing a rotatable drum adapted for holding soiled substrate, a cleaning fluid storage vessel, and a gas vaporizer vessel for recycling used cleaning fluid is provided. The drum is magnetically coupled to a motor so that it can be rotated during the cleaning process. The system is adapted for automation which permits increased energy efficiency as the heating and cooling effect associated with CO.sub.2 gas condensation and expansion can be channeled to heat and cool various parts of the system.

Abstract: The invention provides a cleaning method in which a solvent such as densified carbon dioxide can be used for rapid and efficient cleaning, but with decreased damage to solid components such as buttons. The method comprises contacting a substrate to be cleaned with a first fluid, removing the first fluid from contact with the substrate while replacing with a second fluid, and recovering the substrate substantially free of the first and second fluids and from the contaminant. The first fluid is a densified gas while the second fluid is a compressed gas. A preferred embodiment of the method includes the use of a pretreatment designed for compatibility with the densified first fluid.

Abstract: The present invention provides a package for a phase stable, liquid nonaqueous detergent, comprising:a plastic, relatively thin-walled container, said container having an end wall and a circumscribing side wall which narrows to a finish, and a liquid detergent contained in said container, said detergent comprising:(a) 20-90% of a liquid portion which comprises an alkoxylated nonionic surfactant;(b) 5-50% of a solids portion which comprises:(i) a builder;(ii) 0-20% of the detergent of an oxidant; said solids being stably suspended in said liquid portion, by means of(c) a phase stabilizing amount of a lower alkylated fused ring polyarylene sulfonate; and(d) 0-5% of a hydrolytic enzyme;whereby the phase stability of said liquid detergent in storage in said container is controlled, by the selection of either:(1) said container being constructed of a homopolymeric resin, said container having a minimum average cross-sectional dimension r/2 of at least about 6.

Abstract: The present invention provides a stable liquid, substantially nonaqueous, detergent comprising, by weight percent:(a) 20-90% of a liquid portion which comprises an alkoxylated nonionic surfactant;(b) a solids portion which comprises:(i) 5-50% of a builder;(ii) 0-20% of an oxidant; said solids being stably suspended in said liquid portion, by means of(c) a phase stabilizing amount of a lower alkylated fused ring polyarylene sulfonate; and(d) 0-5% of a hydrolytic enzyme.Further desirable adjuncts may be added to the liquid compositions of this invention.

Abstract: In one embodiment, the invention provides novel low-temperature-effective non-phosphate detergent paste compositions comprising:A concentrated non-phosphate, detergent paste composition which is rapidly soluble in cold water comprising, by weight:(a) about 10-50% of at least one nonionic surfactant;(b) about 5-70% of at least one water insoluble non-phosphate builder;(c) about 0-70% of at lest one water soluble non-phosphate builder;wherein the ratio of (b+c): a is greater than or equal to about 1.0; andwherein the ratio of b:a is less than about 2.0.The novel detergent paste compositions provide good removal of oily and particulate soils from both natural and synthetic fibers and yet surprisingly are rapidly soluble/dispersible in cold water.
