2 High Refractive Index Bead Grade Composition (Silica/TiO2) SH219 Silica 75% TiO2 25% SH219- AS Silica 75% TiO2 25% Refractive Index Surface treatment Silica Bead size / TiO2 crystal size 1.8 none 2~7μm 12nm 1.8 Alkyl silane 2~7 μm 12nm

3 Overview Material Cosmetics by Chemical Cosmetic raw materials have been used separately for different objectives traditionally But Can cosmetic raw materials be hybridized to have multiple functions combined like Digital Convergence in IT industry? For example How about PMMA bead with sensorial effect and UV protection at the same time?

Skin Care Research Lab Kazuhiko Nojima Soft focused Less visible wrinkle Natural look Vivid color No color mismatch Hard focused Visible wrinkle Unnatural look Opaque color Color mismatch Abstract: Generally, inorganic white pigments such as titanium dioxide and zinc oxide have been used in foundations and lipsticks to provide good finish. But there are several problems, such as it s poor dispersion and uneven application color. A new inorganic white pigment, the composite of porous spherical silica including micronized titanium dioxide, can improve these problems and provide a new make-up result. In this paper, optical characteristics of a new white pigment and its application to cosmetics are described.

9 Use of Skin Care Lift+ New Skin Tagespflege Die Straffheit und Glätte jugendlicher Haut sind abhängig von ihrem Kollagengehalt. Mit der Zeit geht die Kollagenproduktion in der Haut jedoch zurück. Die Haut wird schlaff und Falten entstehen. Zusätzlich verlangsamt sich kontinuierlich der natürliche Zellerneuerungsprozess der oberen Hautschicht. Die Produktion neuer vitaler Zellen sinkt und führt dadurch zu einer fahlen, unebenen Haut. Jetzt haben die Laboratoires DIADERMINE Lift+ New Skin entwickelt, eine hauterneuernde Anti-Age-Creme, die die Haut nicht nur intensiv strafft, sondern auch für einen strahlenden, frisch aussehenden Teint sorgt.
