楼主还接着写吗?开头写的很好啊,F大说了一些思路了,就是亲脂,酸碱性这个角度,还有些书是说了一些亲核?nucleophilic, elctrophilic这些角度,很多内容可以深层的讨论啊

我从这个网站上超一段话下来,里面没有提到是和分子大小相关的,反而和汗腺,发囊密度有关。你如果能看到上面的讨论,就知道什么意思了

How does this work? Our skin is somewhat permeable.
The active chemicals in essential oils are absorbed just like the ingredients in common pharmaceuticals such as hormone replacement therapy cream and nicotine patches.
Factors That Increase Skin Absorption
Different factors can affect the absorption of essential oils through the skin. If you massage the area first, it will increase circulation to that area, thereby causing an increase in absorption of essential oils. Heat will likewise increase circulation and thus enhance absorption.
Some researchers report that essential oils may be more readily absorbed from skin locations with greater concentrations of sweat glands and hair follicles, such as the genitals, head, soles, palms, and armpits (Battaglia, 2003).

花水之所以能控油保湿。 这个太有力的证据了,ph至少是一个主要因素, if not all。
tt, 皮肤能吸收的分子量是根据pore的大小算的吗?我记得有文章说大的分子比较金子什么的,只能阻塞毛孔因为分子量太大。水的分子量小,但是从毛孔进入血流反而没有精油分子有效!

楼上jojo说的其实是血液循环的道理啊!
水就是小分子,不能进入人体就是小分子这种说法的有力的反驳证据
提醒jojo把字放大
水能到达皮肤的真皮层?似乎要进入人体组织很难,不然人一进到水里都变成了谁胖子了哈哈。
我昨天在自己的皮肤上做实验,发现皮肤发热的时候吸入精油更快,是在泡澡的时候进行的,皮肤发热,汗囊扩张、毛孔扩张,精油面油在干净的皮肤上很快吸入了,大概3分钟以内就吸收了,血液循环把精油待到了全身(这个可能是我自己臆想的,因为进入身体之后,感觉就交给心理作用那,哈哈)
这就是原因吧!
到底了
