ABSTRACT:
A particulate fabric softening additive for detergent compositions comprises (a) a cellulose ether and (b) an organic fabric softener in intimate mixture. The weight ratio of (a) to (b) is from 1:1 to 0.06:1, such as from 1:4 to 1:9. Component (a) is nonionic, water-soluble with an HLB of 3.3 to 3.8 and a gel point of 33.degree. C. to 56.degree. C. Some commercial alkyl, hydroxyalkyl derivatives satisfying these conditions are disclosed. Component (b) may be a conventional quaternary ammonium salt. By forming these components into an intimate particulate mixture, softening performance is improved.
