    Abstract: Capsules encapsulating an active or functional ingredient are obtainable by a process in which a feed that includes this ingredient is dispersed in the form of drops in a spraying tower and exposed to a temperature in the range of −20° C. to 500° C. In the tower, a cloud of suspended powdering agent provides a coating and prevents the capsules from sticking together and a reactant is provided to react with a polymer or film-forming carrier of the active ingredient so as to modify the water solution properties of the capsule walls.

    Abstract: A method for the production of microcapsules embedded with pharmaceuticals, peptides, proteins, enzymes and vaccines, which uses biodegradable solvents, and microcapsules free of toxic residual solvents is described. The microcapsules are obtained by spraying of a solution, suspension or water-in-oil dispersion of active materials and biodegradable polymers.

    Abstract: Solid core particles encapsulated in a single coat of paraffin wax, the wax having a melting point of about 40.degree. to about 50.degree. C. and a solids content of from 100 to about 35% at 40.degree. C. and from 0 to about 15% at 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 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.
