Abstract
Abstract A spray dried, non-phosphate, substantially unbuilt detergent bead composition post treated with non-ionics, comprising approximately by weight, (a) 2-30% of a dibasic acid component, (b) up to 35% of an anionic, zwitterionic or amphoteric detergent material, (c) up to 5% of a ionic surfactant, (d) 0 to 7% of an alkali metal silicate, the balance being filler.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
149 words
A spray dried, nonphosphate detergent bead composition post treated with a liquid spray containing polyethoxylated nonionic organic detergent in an amount of from about 3 to about 5 percent by weight, the base spray dried bead composition consisting essentially of, approximately by weight, a. 5-25% of an alkali metal salt of a dibasic acid selected from the group consisting of oxalic, malonic, succinic, glutaric, adipic, pimelic,, suberic, azelaic and sebacic acids, b. up to 35% of 1. anionic soap or synthetic organic sulfated or sulfonated detergent, 2. zwitterionic, or 3. amphoteric detergent material, c. 0 to 2% of said nonionic detergent, d. 0 to 7% of an alkali metal silicate, e. the balance being sodium sulfate, said final detergent bead composition containing up to about 6 percent of said nonionic detergent, and said final composition being adapted to yield in aqueous solution a pH of about 7 to 9.
Claim 2
Dependent Claim
