    摘要: 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.

    摘要: Disclosed herein are benefit agent delivery systems which are formed by separately adding to a liquid or granular matrix certain kinds of primary amine compounds and selected types of benefit agents, e.g., perfumes, in the form of aldehydes or ketones. When substrate surfaces are treated with aqueous solutions or dispersions of such delivery systems, the benefit agent is indirectly exposed to and preferably deposited on the substrate surface in such a manner that it provides its benefit to the surface for a longer period of time than when the amine compound is not present. Such benefit agent delivery systems are especially suitable for incorporation into laundry detergent or other fabric-treating products.
