Abstract
This invention relates to organopolysiloxane (silicone) compositions containing an active material chosen to have a desired effect in the composition, such as a perfume, sunscreen, vitamin, drug, biocide, pest repellent, catalyst or cooling agent. The active material is generally an organic material which is not silicon-containing. In particular the invention relates to such composition in which the release of the active material from the composition is inhibited or controlled. The active material is incorporated in a blend of a wax with an organopolysiloxane which has been formed by polymerization in the presence of the wax. It was found that by polymerizing an organopolysiloxane in admixture with molten wax, a stable wax silicone dispersion is obtained which allows ready incorporation of an active material such as a perfume and which releases the perfume only slowly, and may be controlled to release the perfume or other active material in desired circumstances.
