    We investigated a novel artificial membrane to be utilized in the in vitro method for evaluating the photoprotective efficacy of sunscreens. Although other types of membrane have been developed, for example, TransporeTM surgical tape (3M Health Care), problems have been experienced, such as 1) membranes absorb or adsorb UV filters, and 2) the characteristics of their surfaces are far from that of the human skin. We overcame these problems with the development of a new membrane. UV light is highly transparent through our membrane and there is minimal absorption of UV filters. Furthermore, its surface mimics that of the surface of human skin. We can evaluate the efficacy of sunscreens more precisely, and can see the population of UV filters on the membrane surface using luminescence. Thus, our new artificial membrane will make it possible to investigate more effective sunscreen formulations.

    Titanium dioxide (TiO2) has been widely used as a white pigment for various cosmetic products. The finish of lipsticks with this pigment, however, has often made users feel that the color is too white and uneven compared to the appearance of the lipstick because the TiO2 is poorly dispersed and has a strong masking characteristic. To solve this problem, we developed a new type of white pigment (TS-powder). A porous spherical silica including micro-dispersed titanium dioxide. Its main optical properties are higher forward scattering and transparency as compared to ordinary titanium dioxide pigments, thus providing an excellent color effects for lipsticks such as clear appearance on the lips and an even, smooth finish.
