Sci.J 56, 149-150 (March/April) 2005) Abstracts Journal of the Society of Cosmetic Chemists Japan Vol. 38, No. 4, 2004 * Stabilization and Application of Liposomal Structures Containing Sphingoglycolipid and Sterylglycoside Originating in Plants Chihiro Kaise, Teruhisa Kaneko, Shu Uemura The efficacy of corn sphingoglycolipid containing cerebroside and sterylglycoside as a cosmetic material has been studied in terms of its physicochemical stability and skin care effects. As a result of, it was clarified that the optimized corn sphingoglycolipid with a proper ratio of cerebroside and sterylglycoside showed a superb occlusive ability against water evaporation and gave a high moisturizing effect to the skin. Therefore, it was concluded that it could become a promising cosmetic material. Application of Emulsion Technology to Cosmetics Yuji Sakai POLA Chemical Industries, Inc. Skin care cosmetics and emulsions are related closely. The recent emulsion technology has advanced the quality of cosmetics, and cosmetics technology has advanced the study of emulsion. Therefore, cosmetic or emulsion researchers including the author were able to develope highly functional cosmetics by studying the chemical structure of oils and the form of emulsions which are both main factors for emulsion. As for the chemical structure of oils, a study has shown that a high polar oil with unique properties was synthesized, and applied to make - up remover. This study was worthy of notice to connect the properties of the oil and emulsion with the organic conceptual diagram. As for the form of emulsion, it was reported that multiple type emulsion stabilized active ingredients and helped to permeate the skin markedly and employing a high pressure homogenizer brought even higher efficiency. Age - Associated Changes in the Amount of Subcutaneous Tissue in the Face Evaluated in the Ultrasonic B Mode Mayumi Satoh, Shinobu Mori, Hiroshi Nojiri, Naonobu Yoshizuka, Yoshinori Takema Biological Science Laboratories, Kao Corporation In this study, age - associated changes in facial skin, cosmetologically critical factors, were studied in terms of local subcutaneous fat tissue. The subjects were 98 Japanese females evenly chosen from their teens to 70s. On each subject, the thickness of subcutaneous tissue was determined by the ultrasonic B mode method on four facial sites, forehead, orbit, cheek, and mandible. Age - association of the tissue thickness was facial site - dependent. In the orbit, the subcutaneous tissue became thicker with age, whereas it showed a tendency of thinning in the forehead. No clear age association was observed in the cheek or the mandible. To analyze the age * These abstracts appear as they were originally published.
