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)
The film can be used for the preparation of a discharge makeup, with water as solvent, with glycerin, cetyl alcohol palmitate, PEG - 7 ester of olive oil, coconut oleic acid glycerol ester, cetane, polydimethylsiloxane, polysorbate - 80, polysorbate - 20 as emulsifier, with cetyl stearyl alcohol pelargonic acid ester, whales wax Chemicalbook stearic alcohol polyether - 20, cetyl stearyl alcohol, glycerol stearate, cetyl stearyl alcohol polyether - 12 as emollients, phenoxyethanol, hydroxyl methyl benzene as a preservative;Sodium acrylate/acryloyl dimethyl sodium taurine copolymer was used as thickener.Portulaca oleracea extract skin conditioner and flavor preparation.
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:
1.加拿大環境局在國內成分清單上，將該成分列為疑似環境有害物
