  • Patent number: 5578234
    Abstract: The present invention relates to dryer-activated fabric softening compositions and articles, having improved antistatic and/or softening effects, for use in an automatic clothes dryer, especially those comprising, as essential ingredients: (A) fabric softener consisting essentially of: (1) from about 5% to about 95% of preferably biodegradable quaternary ammonium compound selected from the group consisting of the compounds of Formulas I, II, III, and mixtures thereof; (2) from 0% to about 95% highly ethoxylated and/or propoxylated, preferably at least 5 ethylene oxide (EO) and/or propylene oxide (PO) groups per molecule, sugar derivative containing at least one long hydrophobic moiety per molecule; and (3) from 0% to about 95% of carboxylic acid salt of tertiary amine; and (B) from about 1% to about 15%, unsaturated fatty acid having an IV of from about 3 to about 60. The amount of (A) present is at least sufficient to provide softening and/or antistatic effects.
    Type: Grant

  • Patent number: 5348667
    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.

  • Patent number: 5139687
    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.
