The phase diagrams were constructed to recognize the cleansing mechanism In Katsumi Hanada the phase diagram of a water/surfactant/oil system, W/O t yp e microemulsion that solubilizes a small amount of Department of Dermatology, Hirosaki University School of Medicine, 5, Zaifu-cho, Hirosaki 036-8562, Japan For understanding the clinical significance of sunscreen, representative photodermatoses including xeroderma pigmentosa, polymorphous light eruption, chronic actinic dermatitis and porph yr ia were explained. In addition, several topics concerning strategy of sunscreen use were reviewed. Finally, new strategies of sun-protection with metallothionein protein and NF- ,c B decoy were introduced. Development of Oil-T yp e Make-up Remover Prepared with Polyglycerol Fatty Acid Esters water forms near the surfactant-oil axis. Regarding the washing process as proceeding from surfactant-oil axis toward water vertex in the phase diagram, it is supposed that this is the reason why the ordinary remover cannot be used in the presence of water. It was found that the amount of solubilized water could be increased by adding middle- chain alcohols as co-surfactants in the present system. By utilizing a polyglycerol ester of the middle-chain fatty acid instead of such alcohols, the amount of water dissolving in the microemulsion remarkably increased like the added alcohol system Consequently, the make-up remover containing the polyglycerol ester of the middle-chain fatty acid could be used even in a bath, and easily removed the oil soil, dispersed in water as fine emulsion droplet.
