Abstract
A process for making microcapsules may include i) forming a solution of a cross-linker in a liquid; ii) forming a slurry of a surface-modified particulate inorganic material in an aqueous medium; and iii) dispersing the solution of step i) in the slurry of step ii) and causing or allowing the cross-linker to react with the surface-modified particulate inorganic material so as to form a cross-linked microcapsule wall.
