Abstract

We investigated on how the nature of vehicles influenced on the efficacy of mo isturizer s, cutaneous hydrat,ion, physical property and roughness. Hydration was measured with corneometer, physical property with fermometer, and mughness with image analyser. Used vehicles were as follows : hydrous gel, vater in oil(W/0) emulsion, oil in water(0/W) emulsion. I.Jsed moisturizers were as follows . glycerine, polypeptide and sodium lactat,e, hyaluronic acid-triethanolamine, sodium lactate, pvopylene glycol, The results are summarized as follows : 1. The increment of the hydration effect according to vehicles was in this order. C/ W emulsion, W/0 emulsion, hydrous gel(After 2 hours). 2. The increment of extensibility as physical property was correlated to the in crcment, of hydration effcet(r=0.924). 3. It was shown that, the roughness was decreased after treatment of all mo isturizers except propylene glycol but, there was not significant st.atistically and alsa was no meaningful difference among the vehicles. 4. Among t,he moisturizers, glycerine was superior to other moisturizers on the hydration effect and extensihility. We conclude that 0/W emulsion was suitable vehicle on cutaneous hydration effect and hydration effect is proportion to the increment of flexibility.
