- hydrophilic interaction (water-loving)
ion-dipole and dipole-dipole interactions
- hydrophobic interaction (water-hating)
non-polar molecules do not dissolve inwater
- amphpathic : a single molecule has two portion, polarand non-polar
fatty acids form micelles
☆ lowering energy makes the system more stable and more likely to exist

1. Measured 20g ofwater-dry soil
2. Prepared one bottle and put the measured soil in that bottle
3. inject toluene(100ppm, 20ml) in #2 to contamination
4. Close the entrance of the bottle with teflon film and shake bottle more than 24 hours
5. After 24 hours inject methanol, hexane(each 20ml)
6. Shake #5 bottle in 2 minutes and let that sinking
7. Centrifugation that sample and get the sup
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.
Other factors effect penetration of active.
⇒Table 14.
4-1. An active with an acidic pH should be formulated with a pH that
For comparative purposes the corresponding peak-to-background ratios were: 4.4, 7.1 and 7.9 for 5kV, 10kV and 15kV, respectively. In addition to Nb, other elemental peaks could be detected from the surrounding materials. The Al and Si peaks were generated from the holder (the O peak was visible due to oxidation of the holder itself), the Ni peak originated from the sample grid and the extraction
