【求助】有谁知道cetostearyl alcohol的吗？做乳膏用
|
|||
|
Cetostearyl alcohol is a mixture of solid aliphatic alcohols consisting mainly of stearyl (C18H38O) and cetyl (C16H34O) alcohols. The proportion of stearyl to cetyl alcohol varies considerably, but the material usually consists of about 50–70% stearyl alcohol and 20–35% cetyl alcohol, with limits specified in pharmacopeias. The combined stearyl alcohol and cetyl alcohol comprise at least 90% of the material. Small quantities of other alcohols, chiefly myristyl alcohol, make up the remainder of the material. Cetostearyl alcohol 是十八醇和十六醇的混合物，是指用两者物理混合得到的还是以这两种醇为原料合成来的？用来做乳膏有什么优点，国内做乳膏好像很少用到 Cetostearyl alcohol的，不太了解，请教知道的各位，谢谢啦 |
