The present invention relates to a controlled delivery system that can be incorporated in liquid, as well as, dry granular, or powder, household products, such as dishwashing detergents, surface cleaners, deodorizers, animal litters and cleaning wipes The system also prolongs the release rate of the active agents over an extended period of time, or provides heat triggered release of the active agents and yields a high impact fragrance “burst” upon heat treatment. The controlled delivery system of the present invention is a nano-sphere, having an average sphere diameter of from about 0.01 microns to about 10 microns. The nano-sphere comprises hydrophobic materials, cationic conditioning agent or, cationic conditioning agent in conjunction with a cationic charge booster to assist in adhering the spheres onto a surface. |
