  • Patent number: 7378380
    Abstract: A dilutable cleaning composition comprises a pH-elevating component and a pH-lowering component, the composition being such that when it is mixed with water the pH-elevating component dissolves or disperses in the water thereby elevating the pH of the water to at least 8.5 and subsequently the pH-lowering component dissolves or disperses in the water, thereby lowering the pH of the water from at least 8.5 to not more than 4. When the water is at the raised pH, the cleaning composition is effective in removing proteinaceous or fatty soiling, and when the composition is at the lowered pH, the composition is effective at removing alkaline waste materials such as limescale. The cleaning composition is particularly suitable for use as a lavatory or hard surface cleaner.

  • Publication number: 20080118734
    Abstract: A method for forming an active material containing coating on a substrate, which method comprises the steps of: i) introducing one or more gaseous or atomised liquid and/or solid coating-forming materials which undergo chemical bond forming reactions within a plasma environment and one or more active materials which substantially do not undergo chemical bond forming reactions within a plasma environment, into an atmospheric or low pressure non-thermal equilibrium plasma discharge and/or an excited gas stream resulting therefrom, and ii) exposing the substrate to the resulting mixture of atomised coating-forming and at least one active material which are deposited onto the substrate surface to form a coating; wherein the substrate is not a wipe, cloth or sponge for household care or depilatory care or a water solute household cleaning unit dose product.
