J. Cosrnet. Sci.) 55, 307-309 (May/June 2004) Abstracts Journal of the Society of Cosmetic Chemists Japan Vol. 37, No. 1, 2003* A Novel In Vitro Method for Evaluating the Photo protective Efficacy of Sunscreens Akira Ishikubo, Tohru Okamoto, Akira Noda, Hideo Nakajima, Toshio Yanaki, Michihiro Yamaguchi Basic Research Center, Shiseido Co, Ltd. We investigated a novel artificial membrane to be utilized in the in vitro method for evaluating the photo protective efficacy of sunscreens. Although other types of membrane have been developed, for example, TransporeTM surgical tape (3M H�alth Care), problems have been exptaienced, 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. Development of a New Type of White Pigment for Make-up Cosmetics by Controlling Optical Properties Momoko Suzumeji, Masashi Shibata, Kazuhiko Nojima, Hiroyuki Shiomi, Kenichiro Yoshida, Hitoshi Hosokawa Skin Care Research Laboratories, Processing Development Research Laboratories, KAO Corporation Titanium dioxide (Ti02) 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 the color is too white and uneven compared to the appearance of the lipstick because the Ti02 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. Vol. 37, No. 2, 2003 Development of a New Hair Color Simulating Apparatus Toshiyuki Takahashi, Yutaka Tango, Koichi Shimmoto Technical Information Center, Research & Development Division, KOSE Corporation Hair color after dyeing is one of the most important factors in choosing hair dye. Therefore, it is necessary to predict finished hair color after dyeing. However, it is difficult to know the hair color after dyeing becaused people have hair of various colors. In this paper, a new method for predicting the dyed hair state is proposed. Dividing the dyed hair structure into three layers, a layer including melanin as A, a bleach layer as Band a dyed layer as C, the models for predicting the state from the signal response in each layer is introduced. In this method, the equation for the signal response of each layer is introduced using an energy balance, and the state of hair after dyeing is predicted by calculating each equation on the assumption that the signal response of hair before dyeing is equal to the layer A response. In addition, a small apparatus to realize the method has been developed. From the standpoint of the hair color before and after dyeing, the effectiveness of the method is shown. * These abstracts appear as they were originally published.
