  • Patent number: 5855622
    Abstract: A hydrogen peroxide-containing bleach liquor containing one or more compounds selected from organic phosphonic acids and their salts; and a water-soluble alkylamide. A bleaching method comprising using this bleach liquor or this bleach liquor deprived of the water-soluble alkylamide; and performing bleaching with the bleach liquor set at pH 10.0 to 10.7 and heated at 80.degree. to 130.degree. C. (110.degree. to 130.degree. C. in the absence of the alkylamide). The hydrogen peroxide-containing bleach liquor achieves an excellent bleaching effect without using a silicic acid-derived substance which causes a silicate-induced trouble. The bleaching method achieves an unsurpassed bleaching effect by use of the bleach liquor at a temperature in a broad range of 80.degree. to 130.degree. C. under lower alkaline conditions while curtailing the diminution of the physical properties of fibers to be bleached, whether cotton or synthetic fibers.

  • Patent number: 5739095
    Abstract: A solid oxygen-based bleach includes components such as aqueous hydrogen peroxide combined with a quantity of an alkali metal phosphate capable of combining with the hydrogen peroxide to form a peroxyhydrate salt. A sufficient amount of a solidifying agent for the peroxyhydrate salt is added to the mixture while still in its exothermically heated form, to effect solidification of the emulsion upon cooling of the product. The pH of the composition is controlled by addition of sequestering acid salts to maintain the pH within 4 to 9, and preferably 7 to 8. Anionic and/or nonionic surfactants may be added to the composition. The heated molten composition resulting from the exothermic reaction of the constituents is poured into tablet or cake forming molds and allowed to cool thus effecting solidification of the mass in each mold.The bleaching/detergent composition is useful in hot water warewashing, laundry, and hard surface cleaning applications.

  • Patent number: 5723428
    Abstract: Particulate high bulk density non-spray-dried detergent compositions containing organic non-soap surfactant, zeolite builder and fatty acid soap as powder structurant, prepared by non-tower mixing and granulation processes involving in-situ neutralization of fatty acid to soap with aqueous sodium hydroxide, can suffer from localized particle yellowing on storage when perfume and/or fluorescer are present, due to the presence of areas of high alkalinity. Yellowing is reduced without loss of powder structuring if a defined, less than stoichiometric amount of sodium hydroxide is used for the fatty acid neutralization. Surprisingly, in bleaching powders improved bleach stability is also observed. The resulting powder can be defined in terms of a low "basic sodium" content.
