Momentive Performance Materials Introduces: New Micro-spherical Silicone Powder with Spiky Surface

WILTON, CONNECTICUT, 5^TH DECEMBER 2007

Momentive Performance Materials today introduced Tospearl 150KA silicone microspheres with a proprietary, spiky surface that can help the delivery of enhanced soft focus benfits in skin care and color cosmetic products. In addition, Tospearl 150KA microspheres continue to display the outstanding lubricity and buttery feel that is characteristic of Momentive’s Tospearl technology. The INCI name for the new product is Polymethylsilsesquioxane.

Tospearl 150KA microfine spherical silicone resin particles have a three-dimensional network structure. The spikes on the surface cause increased scattering of light that significantly enhances the line blurring and soft focus properties already displayed by Topspearl technology. The main performance benefits of this product, i.e., outstanding lubricity and exceptional line blurring, make it an excellent candidate to consider for the formulation of skin care products, foundations, lipsticks and sunscreens.

Beatriz Blanco, global marketing manager, Momentive Performance Materials, commented, “Tospearl 150KA Microspheres is a great addition to our Tospearl family of silicone Microspheres. At Momentive we are committed to delivering creative technical solutions that provide consumer delight and a luxurious feel. This new powder is an outstanding example of delivering on our promise.”

Momentive Performance Materials offers a wide range of Tospearl microspheres that differ in particle size and range for formulators to consider in supporting multiple performance attributes in skin care, color cosmetics, sunscreens and hair care products.
