主权项

1. A composition comprising porous inorganic oxide particles containing a biologically active ingredient in a liquid material, wherein the inorganic oxide particles possess:
(a) an oil adsorption of about 100 to about 500 ml/100 g; and (b) pores having a pore volume, as measured by nitrogen porosimetry, of about 0.5 cm3/g or greater, wherein said inorganic oxide particles remain free flowing at a weight ratio of liquid material to inorganic oxide particles of at least 1.5:1.
