Abstract
Detergent compositions are disclosed that dissolve completely in cold water. In particular, detergents are disclosed comprising coarse particles having a high bulk density range and a high diameter to density ratio. Processes for the production of such detergents are also disclosed.
Claims10
A particulate detergent composition capable of dissolving completely in water, said composition comprising:
- (a) 75-90% by weight of water soluble alkali metal carbonate, bicarbonate or sesquicarbonate builder salts;
- (b) 1-15% by weight of non-ionic surfactants, and
- (c) 1-15% by weight of water, said composition being in the form of, and consisting essentially of particles having a weighted average particle size of from about 1300-2100 microns, a bulk density of form about 600-1050 grams/liter, and a weighted average particle diameter to bulk density ratio of from about 1.39-2.60 (microns) (liter)/gram.
