发明名称 Delivery system having release inhibitor loaded zeolite and method for making same
摘要 A laundry agent delivery particle and granular compositions including the particle are provided. The particle comprises a porous carrier selected from the group consisting of Zeolite X, Zeolite Y and mixtures thereof with the porous carrier including a number of pore openings. The laundry release inhibitor is then incorporated into the porous carrier so that the cross-sectional area of the release inhibitor is larger than the cross-sectional area of the pore openings of the porous carrier. The laundry release inhibitor includes the residue of a deliverable agent such as a perfume component. The deliverable agent is then entrapped in the porous carrier until the release inhibitor is hydrolyzed thereby releasing the deliverable agent and allowing it to escape from the porous carrier.
