GEL FORMULATIONS FOR EXTENDED RELEASE OF VOLATILE COMPOUNDS

摘要

Disclosed are packing material/matrix and methods of making thereof for slow or extended release of at least one active volatile compound(s). Provided are gel matrix polymerized from particular pre-polymer, and optionally initiators are added during polymerization. The active volatile compounds are encapsulated in molecular encapsulating agents into a form of molecular complex, an the molecular complex is further incorporated into the gel matrix. Also provided are methods for preparing the gel matrix and using thereof.

1. A method of preparing a gel matrix, comprising,
(a) providing an active component comprising a molecular complex of an active volatile compound; and; (b) generating a polymerizable pre-polymer by cross-linking ethylenic unsaturated groups for encapsulating the active component of (a), thereby resulting a matrix with encapsulated active component; and wherein extended release of the active volatile compound is achieved upon contact of a solvent as compared to a control molecular complex without encapsulated in the matrix.
