苯甲醇被网站归类为红色警戒成分，但实际上苯甲醇对部分人造成过敏外，似乎不比其他的防腐成分糟糕?苯甲醇甚至被列为欧盟核可ECOCERT成分， 可添加于宣称天然有机的保养品之中
日本停止生产该防腐剂，但在某些产品中为什么会出现这个成分，例如skii新推出的环采钻白润透晶露/环采臻皙清莹露。既然不提倡添加苯甲醇，为什么要添加在护肤品上！
欧盟这成份也是列管，

2017香港消委会提醒有人会对此香料过敏
一种有机醇，天然存在于一些有机水果(如杏、蔓越莓)和茶中。它主要用作化妆品中的防腐剂，也是刺激性最弱的防腐剂成分之一。
添加大剂量苯甲醇可使产品散发出近似花香的气味，因为苯甲醇也是一些精油如茉莉花精油的芳香物质之一。
作为一种挥发性醇类，当苯甲醇用量较多时会造成皮肤刺激，但它用于化妆品仍然被视为安全的。

【Benzyl Alcohol】
Rating: AVERAGE
Categories: Preservative, Solvent, Texture Enhancer
＊An organic alcohol that can be found naturally in some fruits
＊Serves chiefly as a preservative in cosmetics products
＊Considered one of the least sensitizing preservatives in use
＊Deemed safe for use in concentrations up to 5%
Benzyl alcohol is an organic alcohol that occurs naturally in some fruits (such as peaches, apricots, and cranberries) as well as teas. Recent studies have found topically applied benzyl alcohol might help wound healing by promoting collagen production, however this is not its primary function in cosmetics products. Its chief function in cosmetics is as a preservative, and it’s among the least sensitizing preservatives in use. Benzyl alcohol works well as a preservative because it has both antibacterial and antifungal properties.
High amounts of benzyl alcohol can impart a noticeable floral-like scent to products, as it is part of the fragrance makeup of some essential oils such as jasmine.
As a volatile alcohol, it can pose a risk of sensitivity when used in high amounts but is considered safe as used in cosmetics (usually in concentrations up to 5%, and it may be used up to 10% in hair dyes).
