WAX-ENCAPSULATED PARTICLES AND METHOD FOR MAKING SAME

摘要

Solid core particles encapsulated in a single coat of paraffin wax and a small amount of a wax additive, the wax having a melting point of about 40 to about 50.degree.C. The paraffin coat may comprise 20 to 90% by weight of the particle and may be from 100 to 1,500 microns thick. The coat provides improved stability and prolongs the time in which particles encapsulated therewith may remain active in aqueous environments. The encapsulated particle is made by spraying molten wax onto the particles in a fluidized bed. Liquid or powder cleaning compositions, particularly automatic dishwashing liquid detergents, may incorporate 0.01 to 20% by weight of the composition of the coated wax-encapsulated particles.
