Abstract: Dryer-activated fabric softening compositions and articles having improved antistatic effects, for use in an automatic clothes dryer comprising: (A) at least about 5% of highly ethoxylated, preferably at least 5 ethylene oxide (EO) groups per molecule, sugar derivative containing at least one long hydrophobic moiety per molecule; and, preferably, (B) from about 10% to about 95%, of carboxylic acid salt of tertiary amine. The amount of (A) present is at least sufficient to provide improved antistatic effects and is not so much as to cause the composition to have unacceptable physical characteristics, e.g., stickiness. The active components (A) and (B) can contain unsaturation to provide improved antistatic benefits.

Abstract: A three-step method for preparing textile treatment compositions comprising mixtures of substituted imidazoline fabric softener materials and protonating acids is provided. In Step (1) the imidazoline is heated, and in Step (2) it is protonated in a concentrated acid/water seat. Step (3) comprises diluting this mixture with additional water. Utilizing this method provides compositions having good product stability, dispersibility, and concentratability, as well as excellent fabric softening characteristics.

Abstract: The present invention relates to an aqueous, liquid, hard surface cleaning compositions containing amphoteric/zwitterionic detergent surfactant, specific anionic surfactant, cleaning solvent, optional nonionic detergent surfactant, and buffer. The buffers can be either alkaline or acid for improved cleaning of acid sensitive soils like soap scum and/or hard water deposits. The presence of the specific anionic surfactant permits the inclusion of more of relatively hydrophobic materials like cleaning solvents, which provide improved cleaning, especially under acid conditions where some greasy/oily soils are more difficult to remove.
Abstract: Fatty materials are hydrogenated in a plate heat exchanger at a pressure above about 150 psig. The use of high pressure and high shear as provided by the appropriate surface to volume ratio and pressure drop in the heat exchanger, enables the fatty material to be efficiently hydrogenated, and for touch hardening the temperature can be reduced to minimize the formation of trans-isomers.

Abstract: Cyclodextrin complexes are prepared utilizing processes in which the cyclodextrin/active complex is prepared under concentrated reaction conditions in which there is no more than about 40% solvent, e.g., water, with mechanical working, to provide a complex ultimate particle size of less than about 12 microns and the resulting complex reaction mixture is incorporated, preferably without further operation, into at least one fabric conditioning material, preferably cationic fabric conditioning active, preferably in liquid (molten) form, preferably at a temperature between about 60 and about 95.degree. C., and mechanically worked to reduce complex aggregate particle size below about 200 microns. The resulting complex/fabric conditioning material mixture is used to prepare, e.g., dryer-added fabric softener article, e.g., sheet. The mixture of complex and fabric softener material preferably contains a small amount of an anionic surfactant to help avoid deposition of, e.g.

Abstract: Stable, thickened, aqueous bleaching and cleaning compositions contain hypochlorite and a thickening mixture of high molecular weight polycarboxylate polymer and amine oxide detergent surfactant. Optionally, the compositions can also contain fatty acid, as soap, and/or synthetic anionic bleach stable detergent surfactant. The viscosity is between about 150 and 3,000 centipoises to permit easy dispensing, but still provide a coating action. The compositions are especially good for use in cleaning toilet bowls, bathroom tiles, and shower walls.
Abstract: Detergent compositions comprising a hydrocarbyl-amidoalkyl enebetaine synthetic detergent surfactant; cleaning solvent; and buffer provide superior filming/streaking and good cleaning of hard to remove grease soils. Preferred compositions contain at least one cosurfactant. The compositions can be used to clean glass as well as for general cleaning purposes.
Abstract: Aqueous, liquid hard surface detergent compositions contain beta-aminoalkanols as solvents and/or buffers for improved spotting/filming and good cleaning. Some formulas do not contain large amounts of builders and are suitable for general purpose cleaning including cleaning of glass.
Abstract: Mild soap bars containing low levels of cationic polymeric skin mildness aid, polyethoxylated nonionic detergent surfactant to decrease scum formation and inhibit frosting, i.e., crystallization of nonionic detergent surfactant on the bar surface, and water.

Abstract: An improved process for preparing mono-condensation derivatives of adipic acid with fewer steps and better purity is disclosed. In particular, this process comprises: (a) forming relatively concentrated and pure cyclic monomeric adipic anhydride by depolymerization and concentration starting from polymeric adipic anhydride; and (b) adding a condensation reactant having an active hydrogen, e.g., a primary or secondary amine, to said cyclic monomeric adipic anhydride to form the corresponding mono-condensation derivative of adipic acid.
Abstract: Cyclodextrin complex is suspended in polyalkylene glycol carrier material that does not displace the included material. The preferred perfume/cyclodextrin complexes, either alone or admixed with solvent (e.g., water), are preferably suspended in the carrier and then incorporated into solid, dryer-activated, fabric treatment (conditioning) compositions, preferably containing fabric softeners, more preferably cationic and/or nonionic fabric softeners. The perfume complexes provide fabrics with perfume benefits when they are rewetted after drying. Volatile perfume materials, including those materials that are commonly associated with "freshness" can be applied to the fabrics in an effective way.
Abstract: Fabric softening compositions, preferably in liquid form, for use in the rinse cycle of home laundry operations are improved by: (a) using certain protected water sensitive materials, especially particulate complexes of cyclodextrins and perfumes, which are protected in fabric softening compositions and/or detergent compositions, by e.g.
