ABSTRACT:
A method for washing fabrics at cold water temperatures is provided wherein fabrics are contacted below 50.degree. C. with built detergent particles comprising from 5 to 50% by weight of nonionic detergent active compound, from 15 to 90% by weight of a saturated fatty acid builder salt and from 5 to 80% carrier material chosen from water-insoluble inorganic materials, water-soluble inorganic materials, water-soluble organic materials, or mixtures thereof. The particles are prepared by distributing the aforementioned components in water, mixing the combination, and evaporating water therefrom to obtain the built particles. These built detergent particles are adapted to promote rapid dissolution or dispersion of the particle on contact with water.
