ABSTRACT:
Immiscible components are controllably released into aqueous systems by impregnating silica-silicate open cell foams with the immiscible components. As the silica-silicate foams are gradually dissolved, the immiscible components are released. Fragrance oils and dyes are particularly adaptable for use in the invention. In fact, silica-silicate foams impregnated with fragrance oils having polar functional groups, exhibit an unexpectedly slower rate of dissolution into aqueous environments and consequently, fragrance oils and dyes admixed therewith are released in aqueous systems over extended time periods.
