ENCAPSULATING VOLATILE ORGANIC LIQUID IN AMORPHOUS SILICA PARTICLES

摘要

A method of encapsulating organic liquids for controlled volatilization and release is described, which comprises in one embodiment charging a fine silica into a mixing container which does not inflict shearing force to the contents and adding the liquid (having a viscosity of 50 centipoise or less at 25 DEG C.) onto and mixing with the fine silica in the mixing container.
