Abstract: A stable liquid peracid precursor composition for delivering a bleaching and cleaning material is provided in which the liquid peracid precursor composition combines a dispersion medium which comprises a stabilizing effective amount of a liquid matrix and an emulsifier, and a dispersed phase that comprises a peracid precursor. The bleaching and cleaning material comprises either a hydrophobic or hydrotropic generated mono- or diperoxyacid, or mixtures thereof.

Abstract: A system for removing extraneous, random free-flowing dyes from laundry washing applications which comprises a novel unitary dosing laundry article that can freely circulate among items being laundered. The laundry article further comprises a dye absorber and a dye transfer inhibitor which are introduced into a wash liquor via a support matrix. The dye absorber maintains a relational association with the support matrix in the wash liquor, whereas the dye transfer inhibitor is delivered up from the support matrix to the wash liquor and may be evenly distributed throughout the wash liquor. The laundry article of the present invention provides a method for preventing the redeposition of extraneous dyes onto other wash items, while simultaneously providing an indicator system for the manifestation of such scavenging process.

Abstract: A disinfectant-containing hard surface cleaner composition having increased bacteria count-reducing efficacy is provided by adding thereto a mixture of an alkyl or alkenyl oligoglycoside and certain C.sub.8 -C.sub.18 alkyl ethers.

Abstract: The invention provides a stable, liquid, substantially nonaqueous detergent comprising:at least one imidoperacid with the structure ##STR1## wherein R is C.sub.1-20 alkylene, R.sup.1 and R.sup.2 are individually H or C.sub.1-6 alkyl or alkenyl, or R.sup.1 and R.sup.2 join to form a heterocycle, said imidoperacid being solubilized in a liquid nonionic surfactant. The stable liquid detergent has excellent oxidant and phase stability and, if enzymes are present, maintains proficient enzyme activity.

Abstract: The present invention provides a stable liquid, aqueous enzyme detergent comprising a mixture of nonionic and anionic surfactants, enzymes and a calcium ion source as an enzyme stabilizer, wherein phase instability is prevented by the use of an alkyl ether carboxylate as a phase stabilizer. This material also surprisingly enhances enzyme stability and imparts additional detergency performance to the liquid detergents. Standard adjuncts may be added to the compositions of this invention.

Abstract: Optical brighteners (fluorescent whitener agents) can be made hypochlorite bleach resistant, stable and formulated into concentrated aqueous hypochlorite solutions and into detergent compositions in a manner whereby the whitener agent is transformed into a neutral ion-pair with a surface active quaternary ammonium ion-producing compound.

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 invention provides a phase stable liquid detergent containing at least one insoluble oxidant, comprising:(a) a liquid phase which comprises (i) an effective amount of at least one surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric, zwitterionic surfactants, and mixtures thereof; (ii) a liquid carrier therefore, comprising organic solvents, water, or a mixture thereof; and(b) an effective amount of a water insoluble oxidant stably suspended in said liquid phase, which maintains oxidative stability, said water insoluble oxidant being an alkaline earth metal peroxide or a Group IIB peroxide.

Abstract: The invention provides a homogenous, reduced scratching, liquid abrasive scouring cleanser comprising:(1) about 10-90% by weight scouring abrasive particles with a Mohs hardness of about 2 to 4, wherein a triple tiered weight distribution of said particles comprises(a) about 20-99% of the weight of said particles being particles having a diameter of greater than about 100 microns;(b) about 5-50% of the weight of said particles being particles having a diameter greater than abut 250 microns; and(c) about 0-30% of the weight of said particles being particles having a diameter greater than 300 microns;(2) a soil removal and suspension effective amount of a surfactant system comprising a mixture of anionic and nonionic surfactants; and(3) the remainder, water.Standard adjuncts known to those skilled in the art, namely buffers, colorants, fragrances, thickeners, viscosity modifiers and further surfactants can be added to these cleansers.

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.

Abstract: Timed-release bleaching compounds containing encapsulated hypochlorite bleaching agents are disclosed, along with a method for using the compounds. A preferred embodiment of the invention includes sodium silicate-coated lithium hypochlorite. One or more additional coatings to further delay timed release are optional. The novel bleach compounds are especially useful in reducing fabric and dye damage in fabric bleaching while facilitating the inclusion of optional laundry additives such a enzymes and brighteners. The encapsulates have good shelf stability and are effective over a wide range of temperatures and concentrations.
