Publication number: 20060287219Abstract: 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.Type: ApplicationFiled: August 31, 2006Publication date: December 21, 2006Inventors: Robert Dykstra, Lon Gray, Lois Gallon, Johan Smets, Abdennaceur Fredj, Daniel White
