Effect of chemical structure of polyols and lyotropic series of inorganic salts on foam properties for saponins from Quillaja saponaria Molina (QSM) in aqueous solution was studied. Inorganic/organic balance (IOB), calculated by the organic conceptual diagram, was used as an index value for various polyols. The foam height of QSM in aqueous solution showed a maximum at the IOB value=2.5, while the foam height was decreased before and after IOB value=2.5. On the other hand, the foam height of SDS in aqueous solution was increased in the region of the IOB value=1.6–2.4, as the IOB value increases, and the foam height was kept constant above the IOB value=2.4. Lyotropic series were used on the characteristics of the inorganic salts. The foam height for QSM in aqueous solution was constant without being affected by lyotropic series of inorganic salts. On the other hand, the foam height of SDS in aqueous solution was reduced as the lyotropic series of inorganic salts becomes smaller. Furthermore, the foam stability of QSM and SDS in aqueous solution was discussed in terms of the reduction of surface tension in the presence of these additives.

The Japanese Cosmetic Science Society (JCSS) were organized to establish “Cosmetic Science,” to consider the cosmetic the “Safety” against “Cosmetics pollution,” which caused by the development of the cosmetics industry after the war. And “Safety & functional evaluation guidelines” has been proposed by the Society. Therefore, the JCSS should promote to make useful and safety cosmetics, which is expected, with scientific findings by researchers sincerely. I have been studied on “Psoriasis, ” which is an incurable disease and whose cause is unknown. Namely, researches have been carried out as to the association between HLA (human leukocyte antigen); disease-related genes, and psoriasis. Initially, many dermatologists said “blood type fortune-telling?,” “story like a dream” and so on. In 1979, however, the Japanese Dermatological Association Award was given for this project. And it is now stated “Strong correlation between HLA-C gene in psoriasis” both on Japanese and on international dermatological textbooks. Exactly, the research project has been become to a situation where a dream might come true from the laboratory. Therefore, the slogan was “Let your dream come true from your laboratory!” in the 39th Annual Meeting of JCSS and the following concepts were planned. (1) At all presentations by oral (2) Two special lectures and a symposium of “Aims to further improve the security and trust” (3) “Let's enjoy the Society” Nowadays, social, ethical, economic environment for research, have become quite severe. It is, however, considered that there is great value in that precisely because such a time, to bring fresh ideas, a goal without unwavering, toward the realization of that dream, to move forward. It is really hope that the dream of members in the JCSS, who do his best for his research sincerely, while drawing on the head “Cosmetic that is expected,” in the laboratory will be come true.
