The present invention relates to a controlled delivery system that can be
incorporated in liquid, as well as, dry granular, or powder, fabric care
products, such as fabric softeners, laundry detergents, rinse added
products, and other fabric care products, to enhance fragrance
performance. The controlled delivery system of the present invention is a
solid, substantially spherical particle comprising hydrophobic cationic
charge enhancing agents in conjunction with cationic fabric softening
agents that assist in adhering the particles onto fabric. The particles
can also include a fragrance. The particle can have an average particle
diameter of from about 1 micron to about 500 microns. The controlled
delivery system of the present invention can be utilized to deliver a
broad range of fragrance ingredients onto fabric and prolong fragrance
release from the dry laundered fabric over an extended period of time, or
yield a high impact fragrance "burst" upon ironing the fabric. The
invention also pertains to fabric care products comprising the controlled
release system of the present invention.
