Abstract
Non-aqueous liquid detergent compositions comprising from about 49% to about 99.95% by weight of the composition of a surfactant-containing non-aqueous liquid phase and from about 0.05% to about 51% by weight of the composition of a suspended solid particulate phase wherein the suspended solid particulate phase comprises water-soluble low-density particles which are composed of a binding agent and materials selected from the group consisting of an alkalinity source, a chelant, a builder and mixtures thereof. By the present invention, ingredients which are insoluble in the surfactant-rich liquid phase may be included in the liquid phase without undesirable segregation and separation.
