Sci., 59, 71-72 Qanuary/February 2008) Abstracts Journal of the Society of Cosmetic Chemists Japan Vol. 41, No 3, 2007* Image Analysis of Skin Color Using Independent Component Analysis and Its Application to Melanin Pigmentation Analysis Nobutoshi Ojima Global R&D Beauty Creation, Kao Corporation, 2-1-3, Bunka, Sumida-ku, Tokyo 131-8501, Japan Skin color has conventionally been analyzed by using colorimetric values such as CIE 1976 Ua•b*. Recently, several researchers have reported on extraction techniques of melanin and hemoglobin components from skin color infonnation. One of our recent studies on a practical skin color analysis technique is introduced for evaluating melanin pigmentation, such as freckles. The skin color image is analyzed and separated into hemoglobin, melanin and shading components using the independent component analysis. We pro po se practical measurement systems and describe the results on the seasonal changes and age-related changes of pigmentations, as well as the changes after use of whitening essence. The Stabilization Technology of Superfine Li po some Masaki Matsuo, Issei Hisamitsu, Yasushi Sumida Cosmetics Faculty Fancl Research Institute, FANCL Corporation, 12-13, Kamishinano, Totsuka-ku, Yokohama 244-0806, Japan Generally, hydrophilic surfactants are added to make a small particle size liposome. However, there is a problem that a small particle size li pos ome causes a decrease of its capacity in the internal water phase, and it cannot function well enough as a capsule. Therefore we investigated the effect of various surfactants and lipids on superfine li po some. Finitly, we examined some hydrophilic surfactants which have different molecular structures to minimize the li po somes. PEG-25 phytostanol ether was most effective to make particle size small among nonionic hydrophilic surfactants. However, as the particle size got smaller, its capacity in the internal water phase decreased, being transformed into the micelles. Secondly, we tried to increase the capacity of the internal water phase by adding the combined lipid into the liposome membrane. It was indicated that phytosterol had the po tential to increase remarkably the internal water phase. As a result, we found that it's po ssible to make a li po some of a small particle size having a large capacity in the internal water phase by using both PEG-25 phytostanol ether and phytosterol. Furthermore, the superiority of the li po some which consisted of the above ingredients in electrolyte-resistance was confirmed.
