Spray-dried or spray-cooled soap particles are coated with water-soluble inorganic substances, at least 80% of which are of a particle size below 100 microns. This improves wetting, dispersion and dissolution characteristics. The coating is particularly appropriate to soap particles containing substantial proportions of longer chain unsaturated soaps such as those derived from oleic acid, which tend to be softer than conventional tallow/coconut-derived materials. |
