Abstract
This invention relates to a delivery system for hydrophobic benefit agents to keratinous substrates. The delivery system comprises amphiphilic block copolymers, and a hydrophobic benefit agent, which amphiphilic block copolymers comprise a siloxane segment and a cationic segment. The invention also relates to methods of delivering the hydrophobic benefit agents to the keratinous substrate. Furthermore, the delivery systems and methods of delivery are effective in retaining an hydrophobic benefit agents on the keratinous substrate after rinsing. More particularly, the delivery systems are especially suitable in personal cleansing, body wash or rinse off lotion compositions and comprise certain amphiphilic polymers which effectively deposit the hydrophobic benefit agents onto a keratinous substrate, such as skin or hair.
