of ethanol with silver catalyst
이 방법은 ethanol을 480℃의 공기 하에서 silver catalyst를 이용하여, acetaldehyde를 생산해 내는 방법이다.
2) Wacker oxidation of ethylene
ethylene을 사용함으로써, 위에서 ethanol을 사용하는 방법에 비하여, 더욱 직접적인 방법으로 acetaldehyde를 생산해 내는 방법이다.
3) Hydration of acetald
of actives to penetrate skin.
2-2 IN w/o emulsions, water is slowly released & reaches the upper layers of skin .
Enhanced hydrated skin can result in an additional twofold to threefold increase in the rate of absorption to water & other polar molecules in skin.
3. Occlusive vehicles :
①Suppress transepidermal water loss.
② Increase absorption of actives.

hydration, steric and van der Waals forces, changes in the surface hydrophobicity or conformational changes of the adsorbed molecules play an important role in the final bending.[1],[2] The easiest and most extended model to study the surface stress produced on cantilevers is based on the work of G.G Stoney in 1909. Looking for higher accuracy, some works have presented modifications on this mode
