Abstract
Compositions contenant de l'anhydride silicique et procédé pour leur préparation. Le procéde de l'invention se caractérise par le fait qu'on enrobe les matières actives, éventuellement conjointement avec des produits support, d'un polyalcoxy- et/ou polyorganoal-coxysiloxane liquide et qu'on effectue ensuite une polycondensation hydrolytique. Application notamment à des compositions pharmaceutiques ou pesticides.
