Abstract
A liquid heavy duty laundry detergent composition comprising a suspension of builder salt in liquid nonionic surfactant in which the pourability and physical stability of the composition is improved by the addition of small amounts of an alkaline earth metal or zinc salt of higher fatty acid, especially magnesium, calcium and zinc distearate. The yield stress is reduced and the pourability of the composition is improved especially at low concentrations of the alkaline earth metal or zinc salt.
