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.

Multiple emulsion hard surface cleaning compositions

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.

Dilutable cleaning compositions and their uses

A non-aqueous, single phase, non-thickened liquid air freshener or insecticidal composition having a flashpoint of greater than about 62&#xb0; C. is provided. The composition contains: a) a polar solvent; b) up to about 10 wt % of a non-polar aliphatic hydrocarbon solvent; and c) a fragrance or an insecticide. The composition may be dispensed from a device having a chamber with at least one wall made of a material which enables a vapor of the composition to diffuse out of the chamber.
