<p>Free-flowing base beads, into which nonionic detergent in liquid form may be absorbed to make a free-flowing particulate built synthetic nonionic organic detergent product of improved washing properties, include 15 to 30% of sodium carbonate, 10 to 22% of sodium bicarbonate, 10 to 50% of water softening aluminum silicate (zeolite), O to 18% of sodium silicate, 1 to 20% of bentonite and/or 0.05 to 2% of polyacrylate of molecular weight in the range of 1,000 to 5,000, and 1 to 15% of moisture, together with suitable adjuvants and processing aids in small proportions (normally totalling less than 10% and preferably less than 5%). The presence of bentonite causes the nonionic organic detergent product to leave reduced amounts of deposits, after rinsing, on fabrics washed with such products, while the presence of polyacrylate makes the base beads more absorptive to liquid nonionic detergent and provides improved spray drying operations.</p> |
