Use of a large pore molecular sieve having a pore diameter greater than about 8 Angstroms as agent for the protection and/or controlled release of an active ingredient. Active ingredients suitable for protection and/or controlled release include bleaches and oxidants, bleach activators, bleach catalysts, photoactivators, fabric softening agents, perfumes, flavors, pigments, enzymes, vitamins, pharmaceuticals, antimicrobials, fertilizers, explosives, and corrosive materials. Preferably, the molecular sieve is a mesoporous molecular sieve consisting essentially of crystalline, inorganic material exhibiting after calcination an X-ray diffraction pattern with at least one peak at a d-spacing of at least 18 Angstroms. The active ingredient is physically or chemically sorbed within the pores of the molecular sieve. |
