Abstract
The bleeding out during product storage of nonionic surfactants from powdered detergent compositions containing such surfactants is effectively arrested and retarded with the use of magnesium sulfate heptahydrate as a uniformly distributed and intimately mixed ingredient of such detergent compositions. Advantageously, the magnesium sulfate is mixed with the nonionic surfactant in anhydrous form and hydrated to its heptahydrate form thereafter. A mixture of magnesium sulfate heptahydrate together with polyvinyl alcohol when uniformly distributed within a detergent composition is also effective in arresting and retarding nonionic surfactant bleeding.
