BUILT LIQUID DETERGENT COMPOSITIONS AND METHOD OF PREPARATION

摘要

A stable homogeneous aqueous liquid detergent composition contains 22 to 35% by weight of sodium tripolyphosphate and 6 to 15% by weight of an active detergent mixture comprising (a) a water-soluble anionic sulphonate or sulphate detergent; (b) an alkali metal soap of fatty acids having 12 to 18 carbon atoms, and (c) a nonionic detergent, in a weight ratio of (5.5-8.5):(0.5-3):(1.5-3). The composition is a pourable liquid having a viscosity of 0.35-1.0 Pa s measured at 20 DEG C. and at 21 seconds-1 shear rate and remaining stable after at least two 24-hour cycles of from -4 DEG C. to ambient temperature. Preferably the composition is prepared by mixing the ingredients in the proper sequence.
