He is a Fellow of the Chemical Society of Japan and was a Chairman of Division of Colloid and Surface Chemistry at The Chemical Society of Japan for 2007-2008. In these capacities he conducts fundamental research in the field of cosmetic science. He has 37 years of industrial carrier for the R&D and international marketing of cosmetic ingredients and products at Ajinomoto Co., Inc. (33 years), Shiseido Res. Cent. (3 years), and Seiwa Kasei (2 years). As well as working in industry, Dr Sakamoto has been active in research and educations at Universities as Yokohama National University, Shinsyu University then Tokyo University of Science as an adjunct professor. After retiring from industry in 2008, he has been expanding academic activities. His study "Self-Organization of Amino Acid Based Chiral Surfactants: Evaluation of Organized Structures and Interactions with Biological System? was awarded by Japan Oils Chemists' Society in 2005. He has been actively participating in many international conferences as an invited speaker over the past decade and more. Robert Y. Lochhead is Professor and Director Emeritus of Polymer Science and High-Performance Materials at the University of Southern Mississippi, USA. Following a 25-year career with I.C.I., Unilever, and BF Goodrich, Bob Joined academia and served as Professor, Chair and Director of the School of Polymers and High-Performance Materials at the University of Southern Mississippi. After retirement from the university in 2016, Bob founded Robert Lochhead Consulting LLC. Bob has served twice as the President of the SCC, and as President of the International Association of Formulation Chemists. Bob is a fellow of the SCC and a Fellow of the Royal Society of Chemistry. Among other honors, he is a recipient of the SCC's Maison G. DeNavarre Medal Award, the SCC'S Merit Award, the AIC's Chemical Pioneer Award, and the Society of Plastics Engineers' Education Award. ?Bob received the SCC's Lifetime Service Award in December 2019 and was named one of the first three Fellows of the IFSCC in 2020. Howard Maibach is a Professor at the Department of Dermatology at UCSF, USA. He is an expert in contact and occupational dermatitis and sees patients at the Environmental Dermatosis Clinic, which is part of the Dermatology Clinic. His specialty is dermatotoxicology, or skin exposure toxicity; allergies and skin disorders; and dermatopharmacology or the study of medications for skin disorders. Maibach has been on the editorial board of more than 30 scientific journals and is a member of 19 professional societies including the American Academy of Dermatology, San Francisco Dermatological Society, and the Internal Commission on Occupation Health.

His current research programs include defining the chemical-biologic faces of irritant dermatitis and the study of percutaneous penetration. When Dr Maibach is not in the lab conducting research or in the classroom teaching, he is seeing patients at the Environmental Dermatoses Clinic (of the Dermatology Clinic), mostly providing second opinions on allergic contact dermatitis. Yuji Yamashita is an Associate Professor at the Faculty of Pharmacy, Chiba Institute of Science (CIS), Japan. He received his Ph.D. in natural science from Bayreuth University, Germany, in 2005, plus an M. S. and B. S. from Yokohama National University, Japan. After several years of research work on the thermotropic liquid crystals

in industry laboratory at Chisso Petrochemical Co., Japan, he began to study dermatology, especially transdermal drug delivery system, as a post-doc at St. Marianna University, Japan. Since October 2011, he has been engaged in teaching and research concerning cosmetic science as an assistant professor at Chiba Institute of Science, Japan. The area of his expertise is the

surfactant science such as phase behavior and self-assembly which is related to formulation technology.
