11220P6GB 2401 875 Aqueous Cleaning Compositions The present invention relates to an aqueous liquid fabric detergent that contains a new thickening system, and the use of such compositions in cleaning fabric.

An objective of the present invention is to provide a base composition which is stable and to which ingredients typically found in fabric detergents can be added without any major negative impacts on the comparability of the ingredients. In particular the composition is stable to light, in particular UV light. Preferably the product should also be physically lo stable, as well as chemically stable. Ideally the product is viscose and has a viscosity of greater than 100 cps, preferably greater than 300, 400 or 500 (as measured in a Brookfield viscometer at 20 C, spindle no.2 and 1 S rpm). In addition, preferably, the base composition and the final product is transparent.
