Abstract: A method of delivering a primary active agent and a secondary active agent to a locus. The method uses a polymersome containing composition. The composition comprises a plurality of polymersome vesicles containing the secondary active agent and a liquid matrix comprising the primary active agent. The polymersome vesicles are capable of being disrupted by the application of mechanical shear.

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.

Abstract: A method is provided for deactivating a Der-p and/or Der-f allergen which comprises volatilizing into a space to be treated a deactivating amount of a volatile oil selected from cajeput oil (tea tree oil) or an oil comprising one or more terpene hydrocarbons.

Abstract: A liquid cleaning composition and a solid state catalyst are provided in combination. The solid state catalyst causes a chemical reaction in the liquid cleaning composition, when the liquid cleaning composition is brought into contact with it. The chemical reaction may increase the oxidising power of the liquid cleaning composition, or change its pH, or cause gas evolution, or release heat.

Abstract: A device for dispensing a fluid at a locus comprises a reservoir 2 of fluid in liquid form, a syphonic-action elongate liquid delivery means 12 having a proximal end 14 inside the reservoir adjacent the bottom thereof and a distal end 16 from which the fluid is dispensed as a liquid or as a vapour.

Abstract: A cleaning composition comprising from 30 to 70 percent by weight of 1-alkyl-2-pyrrolidone, from 25 to 45 percent by weight of hydrocarbon and from 5 to 25 percent by weight of water exhibits good cleaning performance and a visual indication of activity. The composition is on or adjacent to a phase boundary of its phase diagram and exhibits self-induced surface motility of the Marangoni type.

Abstract: A method of deactivating Der P and Der f allergens involves dispersing into an airspace an allergen deactivant, The deactivant being provided in a vessel and the vessel being in contact with a hotplate.

Abstract: A method of deactivating an allergen comprises dispersing into an airspace containing or able to support said allergen an allergen-deactivating amount of an allergen-deactivating compound, the compound comprising one or more of the following compounds: a citrus oil; a mint oil; bois de rose oil; oil of jasmine; frankincense; oil of bergamot; and oil of lemon grass.

Abstract: A cleaning article comprises a substrate in the form of a wipe loaded with a cleaning agent and loaded with a heat generating agent which generates heat when the wipe is exposed to water.

Abstract: The present invention provides a cleaning composition comprising a multiple emulsion system, wherein said emulsion system comprises at least two active ingredients separated in the emulsion system by an oily or aqueous phase. Also described is the use of such multiple emulsion systems as cleaning compositions, and a method of cleaning a surface using multiple emulsion systems.

Abstract: Cleaning compositions including a photocatalytic material and a sensitiser employ a photocatalytic material and a sensitiser at a locus, for example on a surface. The residue combats soils and/or undesired microorganisms at the locus. The photocatalytic material is peroxo modified titania, preferably in its anatase form, or peroxo modified titanic acid, or a mixture thereof. The compositions are preferably alkaline.

Abstract: An article for sequential dispensing of vapours, notably evaporable fragrances, comprises separated first and second liquids (22, 24). Liquid (22) issues first. Its evaporation may be assisted by a wick (26). The simultaneous evaporation of the second liquid is prevented by an intermediate liquid phase (20). As liquid (22) issues the liquid levels change and there comes a point at which the intermediate phase can no longer prevent the second liquid (24) from flowing past it, to the region from which it can be evaporated. Solids, especially gels, may be employed instead of liquids (22, 24).

Abstract: The present invention provides a pump comprising a container containing a dispense material, an outlet therefrom and an actuator arranged to alternate between first and second configurations in response to a change in the pump's environment, to cause an aliquot of dispense material to be expelled through the outlet.
