The present invention is a
controlled delivery system that can be incorporated in hair,
skin, and fabric care products such as shampoos, conditioners, hair styling products, lotions, creams, liquid
laundry detergents,
fabric softener, and other hair,
skin, and fabric care products to effectively deliver a broad range of active agents and sensory markers onto the hair,
skin, and fabric. The
system also prolongs the release rate of the active agents or sensory markers over an extended period of time, or provides heat
triggered release of the active agents and yields a high
impact fragrance “burst” upon blow
drying the hair, ironing the fabric, or other types of 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 hair, skin, and fabric. The invention further relates to a
controlled delivery system where the release rate of the active ingredients is synchronized with that of a sensory marker to convey to the
consumer the product performance.
