请问Cetearyl Alcohol(棕榈醇, 鲸蜡硬脂醇)这个界面活性剂属于哪一个类别，是阴离子型、阳离子型、两性型、非离子型哪一种?
Although yea it’s considered to be one of the more fatty and moisturizing alcohols it’s still an alcohol that can irritate sensitive skin and many people have been known to break out from it, myself included. Obviously everyone’s skin is different though so patch test any products with this ingredient just to be safe. (But if you really rather be safe than sorry maybe consider steering clear of any and all products with this and other alcohols)

应用：乳液/乳霜、润髮/护髮…等乳化体之增稠。
Cetearyl Alcohol becomes comedogenic when listed together with Ceteareth 20. On it's own, it is fine for the vast majority of people with acne prone skin.
化妆品中为什么要使用鲸蜡醇？
鲸蜡醇作为一种粘合剂，有助于多种保湿剂、乳液和面霜中各种成分粘合，保证顺利使用
近 30 年来，化妆品成分审查 (CIR) 专家科学小组一直指出，鲸蜡醇是一种安全的化学品成分。2005 年，CIR 审查了现有新数据，再次确认原来的安全性结论。
少数人在接触乳液或面霜中的鲸蜡醇等乳化成分时，会出现接触性过敏(皮肤发红或发炎)。
美国食品药品管理局 (FDA) 认为鲸蜡醇可以安全地用作直接和间接食品添加剂。
美国ewg认证等级为1分, 即低风险，但数据量有限。ewg里面显示:

Cetearyl Alcohol at a Glance
Fatty alcohol with emollient (softening/smoothing) properties for skin
Known to be gentle and safe (unlike skin-damaging/drying forms of alcohol such as SD or denatured)
May also be used to alter the thickness of a formula or influence the foaming capacity of a cleanser
Can be derived naturally, as in coconut fatty alcohol, or made synthetically
As a raw material, it is a white, waxy solid (often in flake form)
Cetearyl Alcohol Description
Cetearyl alcohol is a fatty alcohol that is a mixture of cetyl and stearyl alcohols. It can be derived naturally, as in coconut fatty alcohol, or made synthetically. Unlike the skin-aggravating/drying forms of alcohol (typically listed as SD alcohol, denatured alcohol, or isopropyl alcohol), cetearyl alcohol is an emollient that is gentle, safe, and good for skin.
Beyond cetearyl alcohol’s emollient ability to provide a softening and smoothing effect, it is also used as a carrying agent for other ingredients. Additionally, it can be used to alter the thickness of a formula or to influence the foaming capacity of a cleanser.
It is almost always combined with similar-feeling ingredients to create a product’s texture and slip sensation when applied to skin.
According to the U.S. FDA, cosmetic products labeled “alcohol free” are allowed to contain cetearyl alcohol, because the effects are so different from skin-damaging forms of alcohol. We repeat: fatty alcohols like cetearyl alcohol do not pose a risk of sensitizing or drying out your skin.
As a raw material, cetearyl alcohol is a white, waxy solid (often in flake form). It is not soluble in water but is soluble in alcohol and oils. In the majority of skin care formulas, cetearyl alcohol is present in under a 5% concentration, although higher amounts are permissible.
The Cosmetic Ingredient Review has a long history of recognizing cetearyl alcohol as safe in the present practices of use.
