  • Publication number: 20020002130
    Abstract: A spray-dried amorphous alkali metal silicate compound which provides multiple-cycle washing performance. The silicate compound has a molar ratio of M2O to SiO2 of 1:1.5 to 1:3.3 wherein M represents an alkali metal. The compound contains 0.5 to less than 30% by weight of anionic surfactant and has an absorption capacity for liquid components which is at least 20% higher than that of the same quantity of the alkali metal silicate compound which is free from anionic surfactant.

  • Patent number: 6133214
    Abstract: A portioned detergent composition in a bag of water-soluble film in which at least 70% by weight of the particles of the detergent composition have particle sizes above 800 .mu.m. The choice of this particular particle size range eliminates otherwise typical production-related problems arising out of the permeability of the bag seams and resulting difficulties.

  • Patent number: 5399271
    Abstract: An article for treating washed laundry in a tumble dryer to provide the laundry with a pleasant, soft and full feel, and antistatic properties. The article is a flexible sheet-form substrate coated with a mixture of (a) a fatty component selected from a fatty acid mono-, di-, and tri-glyceride, a fatty acid and a fatty alcohol, and (b) a fatty acid ester of a monohydric alcohol.

  • Patent number: 4965014
    Abstract: The invention relates to a liquid mixture of propylene oxide-ethylene oxide derivatives of alcohols corresponding to the following formulaR--O--C.sub.3 H.sub.5 O.sub.1-2 --(C.sub.2 H.sub.4 O).sub.6-8 --Hin which R is a linear alkyl or alkenyl radical which may be methyl-branched in the 2-position, and which has the following chain distribution: C.sub.8 =0 to 5%, C.sub.9-10 =75 to 90%, C.sub.11-12 =5 to 15%, C.sub.13-14 =4 to 10%, C.sub.15-16 =0 to 3%. By virtue of its physical and washing-active properties, the mixing is suitable as a readily biodegradable substitute for alkylphenol ethoxylates.

  • Patent number: 4846997
    Abstract: Monosodium cyanamide is suspended in chemically and physically stable form in certain, high-boiling ether alcohols corresponding to the following formula ##STR1## The suspensios are an easy-to-handle, meterable form of NaHNCN in which it may be used both as a starting material for chemical syntheses and as an activator for peroxidic bleaches.
