STRUCTURED DETERGENT PARTICLES AND GRANULAR DETERGENT COMPOSITIONS CONTAINING THEREOF

摘要

This relates to structured detergent particles with mid-level surfactant activity, which contain 35-50 wt％ of a C10-C20 linear alkyl benzene sulphonate, 0.5-8 wt％ of a hydrophilic silica, 35-70 wt％ of a water-soluble alkaline metal carbonate, 0-5 wt％ of a phosphate builder, and 0-5 wt％ of a zeolite builder. Such structured detergent particles are free flowing with little or no moisture content (i. e., 0-3 wt％ water), and are formed by a dry neutralization process without any subsequent drying.
