A granular spray-dried detergent base composition is provided which exhibits a high porosity and can take up large amounts of nonionic surfactant material while maintaining good powder properties. This base composition comprises: (i) an organic surfactant system consisting essentially of from 7 to 40 wt. % of fatty acid soap, (ii) a detergency builder system consisting essentially of from 28 to 80 wt. % (anhydrous basis) of crystalline or amorphous alkali metal aluminosilicate, (iii) optionally other detergent ingredients, and moisture to 100 wt. %, the base composition containing not more than 5 wt. % of sodium carbonate and sodium sulphate, all percentages being calculated on the base composition. |
