Anti-aging is probably the most important global trend in the cosmetics and personal care market today. In response to the rapid growth of the anti-aging segment of the personal care market, Shin-Etsu Silicones of America (SESA: a U.S. subsidiary of Shin-Etsu Chemical Co. Ltd., Japan), has recently premiered its KSP series of high performance hybrid spherical silicone powders (KSP-441/KSP-411) that contain a silicone core along with a silicone resin shell. Presented at the Society of Cosmetic Chemists (SCC) 2011 Technology Showcase, this unique hybrid combination achieves a superior "soft-focus" effect.
SESA's hybrid KSP powders combine a unique "rubber core-resin shell" structure designed to deliver consumers perceivable visual benefits (soft focus, matte, natural, transparent) as well as superior feel properties (smooth, silky, moist). Additionally, each powder is designed to absorb specific oil types: the KSP-411 (INCI: Polysilicone-1 Crosspolymer) for silicone oils and some light esters, and the KSP-441 (INCI: Polysilicone-22) for organic oils and sebum absorption that provides anti-shine benefits.
