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.
Particule de libération d'un agent pour la lessive et compositions granulaires contenant cette particule. Cette dernière comprend un véhicule poreux choisi dans le groupe composé de zéolite X, zéolite Y et des mélanges de ceux-ci, et présentant un certain nombre de pores. Un inhibiteur de libération est ensuite incorporé dans le véhicule poreux de telle sorte que l'aire de section de l'inhibiteur soit plus importante que celle des pores du véhicule poreux. L'inhibiteur comprend le reste d'un agent libérable, tel qu'un constituant de parfum. Cet agent libérable est ensuite piégé dans le véhicule poreux jusqu'à ce que l'inhibiteur de libération soit hydrolysé de sorte qu'il libère l'agent libérable et lui permette de s'échapper du véhicule poreux.
