Abstract (en)
Granular detergents containing organic surfactant, pyrophosphate and tripolyphosphate builders at a weight ratio of pyrophosphate to tripolyphosphate of from about 50:1 to about 1:1, and low levels of silicate are disclosed. The compositions are prepared by drying an aqueous slurry of the components, and exhibit improved structure, physical properties and whiteness maintenance due to the incorporation of the tripolyphosphate.
