ABSTRACT:
A particulate composition comprises particles having a substantially anhydrous core comprising an active ingredient. Generally the core comprises a matrix polymer with the active ingredient distributed throughout this. Generally there is an outer protection shell of polymer, generally formed by coacervation. The invention is a value for the production of powders, dispersions in non-aqueous liquids (for instance when the active ingredient is a detergent enzyme) and dispersions in water (for instance when the active ingredient is an agrochemical.
