Process for encapsulating particles and the encapsulated product of that process

Abstract

High efficiency encapsulation of core particles, particularly halogen bleaches, by (i) encapsulating the core particle in at least two separate coats wherein the melting point of the inner or first coating material is below the melting point of the outer or second coating material, (ii) heating the thus encapsulated particle to a temperature between the melting points of the inner and outer coating materials in order to liquefy the inner coat, and (ill) allowing the liquid inner coat to solidify and form a continuous, nonporous encapsulating coating.
