  • Patent number: 5384186
    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.

  • Patent number: 4314949
    Abstract: An improved process, preferably continuous, for making a peroxyacid having about 6 to 18, preferably about 8 to 16 carbon atoms and at least one peroxyacid moiety, using as starting materials the corresponding carboxylic acid and hydrogen peroxide and using concentrated acid as the reaction medium, comprising the steps of (a) maintaining a reaction mixture having a liquid component comprising 60 to 80% concentrated acid, 2.5 to 12.5% hydrogen peroxide, and 7.5 to 37.5 % water and a dispersed solid component comprising crystals of the carboxylic acid starting material and peroxyacid product, the ratio of liquid to solids being from about 15:1 to about 49:1. Preferably the carboxylic acid is added as particles having a size of less than #100 mesh to a preformed solution of the concentrated acid and peroxide.

  • Patent number: 4005030
    Abstract: A detergent composition containing an anionic detergent and an organosilane is capable of imparting soil release benefits to hard surfaces washed therewith. Soil adheres to such surfaces less strongly thereby making them easier to clean. The detergent composition can be formulated for use in a wide range of applications, e.g., as a light duty liquid composition, car wash composition, oven cleaner, window cleaner or toilet bowl cleaner.
