Abstract
New granular detergent compositions suitable for heavy duty laundry and automatic dishwashing applications are disclosed. The detergents contain organic surfactant combined with a siliconate-silicate product that provides the compositions with improved dissolution characteristics in water. The siliconate-silicate component contains silicate units and anionic functional organosiliconate units represented by the formula (MO).sub.a O.sub.(3-a)/2 Si--R--Y.sub.b wherein Y represents the anionic functional group, R is an organic linking group, b is an integer from 1 to 3, a has a value of from 0.5 to 2, and M is hydrogen or alkali metal.
