The invention is directed to a method for the encapsulation of liquids within a continuous impervious coating of thermoplastic material. The method is carried out with continuous agitation during which the adsorbent and adsorbate are coated with a plurality of sprayed layers of thermoplastic coating material while maintaining the adsorbent in free-flowing powder consistency during the coating steps. The method is especially advantageous for the encapsulation of volatile liquids.
