  • Publication number: 20060287219
    Abstract: 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.
