摘要: A process is provided for preparing encapsulated active particles by the steps of: dispersing materials in molten wax; emulsifying active/wax dispersion aqueous surfactant solution no longer than 4 minutes; quenching capsules cooling; and retrieving solidified capsules. The may be selected from chlorine or oxygen bleaching agents, bleach precursors, enzymes, perfumes, fabric softening surfactants. Optimal are obtainable where a blend of hard soft waxes utilized coating. characterized needle penetration values higher 30 mm lower 35 mm, respectively, at 25° C. resultant have utility cleaning compositions such as automatic dishwashing detergent formulations.
