    • A laundry agent delivery particle is provided. The particle comprises: a) a porous carrier selected from the group consisting of Zeolite X, Zeolite Y and mixtures thereof, the porous carrier including a number of pore openings; and b) a release barrier having at least one deliverable agent residue and at least one size enlarging agent residue, the deliverable agent residue being incorporated into the porous carrier, the size enlarging agent residue having a hydrophilic portion and a hydrophobic portion, the hydrophilic portion incorporated into the porous carrier and in conjunction with the deliverable agent residue forming the release barrier wherein the cross-sectional area of the release barrier within the porous carrier is larger than the cross-sectional area of the pore openings of the porous carrier. Preferred size enlarging agents include those having a fatty chain or alcohol chain in the hydrophobic portion, such as nonionic surfactants. Preferably, the particle is added to a granular detergent composition.
