ABSTRACT:
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.
