Soap powders and a process for their manufacture |
(57) 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.
