  • Patent number: 7259134
    Abstract: Single or multi-compartment detergent pouch having walls composed of a water-soluble or dispersible water-containing polymer film, the pouch having at least one compartment containing a liquid composition and preferably at least one compartment containing a hygroscopic powder composition characterised in that the liquid composition comprises a moisture regulator system such that at equilibrium at 40% relative humidity and 21.1° C. (70° F.) the amount of water in the film is within about 30%, preferably within about 10% of that of the native film.

  • Patent number: 6172033
    Abstract: A process for conditioning pastes comprising at least 40% by weight of anionic surfactant is provided. The paste is conditioned by mixing alkyl sulphate powder with the surfactant paste in a ratio of at least 1 part powder to 100 parts paste. This conditioning step increases the viscosity of the surfactant paste. The conditioned paste is processed into agglomerates by granulating with builder powders wherein the ratio of high viscosity paste to builder powder is from 9:1 to 1:5. This process enables detergent agglomerates with high surfactant activity to be formed.
