ABSTRACT:
The present invention provides methods for microencapsulation of active ingredients for topical application, whereby double-layer and triple-layer microcapsules are obtained. The microcapsules protect the active ingredients, maintain their original activity throughout processing, formulation and storage, and enable controlled release of the active ingredient only upon application onto the skin.
