Method of loading a volatile hydrophobic material into a non-porous solid article

Abstract

A method of preparing a product for the release of volatile hydrophobic material includes (i) providing a solid article comprising a polymer gel matrix formed from a chemically cross-linked material; and (ii) absorbing the volatile hydrophobic material into the solid article by contacting the solid article with liquid phase volatile hydrophobic material until the solid article comprises at least 5 wt % of the volatile hydrophobic material, based on a final weight of the solid article. The solid article is non-porous. The product is able to provide release of the volatile hydrophobic material by volatilization of the volatile hydrophobic material from the solid article at a temperature of 25° C., a relative humidity of 60%, and atmospheric pressure.
