Cool water fabric washing process using a particulate detergent containing a nonionic and a fatty acid builder salt
First Claim
1. A method for washing fabrics at cold water temperatures comprising contacting said fabrics below 5020 C. with built detergent particles comprising:
- (i) from 5 to 50% by weight of a nonionic detergent active compound;
(ii) from 15 to 90% by weight of a saturated fatty acid builder salt containing at least 16 carbon atoms, or mixtures thereof; and
(iii) from 5 to 80% by weight of a carrier material, the carrier material being chosen from water-insoluble inorganic materials, water-soluble inorganic materials, water-soluble organic materials selected from the group consisting of urea, solid polyhydric alcohols, polysaccharides, synthetic polymers, proteins, and mixtures thereof; and
wherein said particles are prepared by distributing said nonionic active, said fatty acid builder salt, and said carrier material in water to form an aqueous solution and/or dispersion, mixing said combination, and evaporating water therefrom to obtain said built particles.

Abstract
A method for washing fabrics at cold water temperatures is provided wherein fabrics are contacted below 50° 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.
