請問Cetearyl Alcohol(棕櫚醇, 鯨蠟硬脂醇)這個界面活性劑屬於哪一個類別，是陰離子型、陽離子型、兩性型、非離子型哪一種?
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)

鯨蠟硬脂醇 (1618醇) Cetostearyl Alcohol
外觀：白色顆粒
作用：賦脂劑、滋潤用、調節膏體或乳液的稠度、軟硬度、觸變性，使乳化產品安定性更優異。幫助乳化產品提供更一致的稠度，達成增加硬度、乳化穩定性之效果。
應用：乳液/乳霜、潤髮/護髮…等乳化體之增稠。
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.
化妝品中為什麼要使用鯨蠟醇？
鯨蠟醇作為一種粘合劑，有助於多種保濕劑、乳液和面霜中各種成分粘合，保證順利使用
近 30 年來，化妝品成分審查 (CIR) 專家科學小組一直指出，鯨蠟醇是一種安全的化學品成分。2005 年，CIR 審查了現有新數據，再次確認原來的安全性結論。
少數人在接觸乳液或面霜中的鯨蠟醇等乳化成分時，會出現接觸性過敏(皮膚發紅或發炎)。
美國食品藥品管理局 (FDA) 認為鯨蠟醇可以安全地用作直接和間接食品添加劑。
美國ewg認證等級為1分, 即低風險，但數據量有限。ewg裏面顯示:

CETEARYL ALCOHOL
TYPE OF INGREDIENT: Emulsifier
MAIN BENEFITS: Stabilizes products, prevents separation, and thickens.
WHO SHOULD USE IT: In general, anyone who doesn't have an allergy can safely use cetearyl alcohol.
HOW OFTEN CAN YOU USE IT: Daily.
WORKS WELL WITH: Most other emulsifiers.
DON'T USE WITH: Cetearyl alcohol is safe to use with most other ingredients, but it can be comedogenic when used in conjunction with ceteareth-20, according to Fusco.

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.
