Detergents and methods for producing the same

High density, readily dispersable detergent comprises: (a) 15-20% nonionic surfactant; and (b) 30-45% blend of light density sodium carbonate of density 0.5-0.56 g/ml and a medium light density sodium carbonate of density 0.6-0.65 g/ml in a ratio of (65:35)-(30:70) with respect to one another. Also claimed are: (1) high density, readily dispersable powder detergent composition comprising: (a') 15-20% nonionic surfactant; (b) 10-17% sodium carbonate of density 0.5-0.56 g/ml; and (c) 15.5-32.5% sodium carbonate of density 0.6-0.65 g/ml; and (2) optimising the bulk density and dispensibility from an automatic dispensing washing machine of a nonionic detergent composition comprising using 30-45 wt.% of the above specified blend of medium light density and light density sodium carbonate along with 15-20 wt.% of the nonionic surfactant. Advantage - The blend of light density and medium light density sodium carbonate provides improved dispensing characteristics while maintaining high bulk density. The blend also provides improved flow characteristics to the detergent composition.
