ABSTRACT:
Low phosphate, light density, laundry detergent powder compositions, comprising an agglomerated mixture of expanded borax of bulk density of approximately 12 to 20 pounds per cubic foot as a carrier, additional builders, other adjuvants and organic liquid surfactants, such detergent compositions being produced by an economical cold spray-mix process under controlled and relatively anhydrous conditions. The weight percent of expanded borax of low bulk density is about 10% to 80%, preferably about 15% to 35%, and the weight percent of the organic liquid surfactant is 5% to 25%, typically 13% to 18%, of the detergent powder product. The phosphate content of the composition is not more than 5% based on P.sub.2 O.sub.5.
