STRUCTURED DETERGENT PARTICLES AND GRANULAR DETERGENT COMPOSITIONS CONTAINING THE SAME

摘要

A structured detergent particle with mid-level surfactant activity, which contains 35-50 wt% of a C 10-C 20 linear alkyl benzene sulphonate, 0.5-8 wt% of a hydrophilic silica, 40-60 wt% of a water-soluble alkaline metal carbonate, 0-5 wt% of a phosphate builder. Such structured detergent particles are free flowing with little or no moisture content, and are formed by a dry neutralization process without any subsequent drying.
