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)

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:
