屬低度皮膚過敏危險性[1]。
苯甲醇被網站歸類為紅色警戒成分，但實際上苯甲醇對部分人造成過敏外，似乎不比其他的防腐成分糟糕?苯甲醇甚至被列為歐盟核可ECOCERT成分， 可添加於宣稱天然有機的保養品之中
日本停止生產該防腐劑，但在某些產品中為什麼會出現這個成分，例如skii新推出的環采鑽白潤透晶露/環采臻皙清瑩露。既然不提倡添加苯甲醇，為什麼要添加在護膚品上！
歐盟這成份也是列管，

2017香港消委會提醒有人會對此香料過敏
一種有機醇，天然存在於一些有機水果(如杏、蔓越莓)和茶中。它主要用作化妝品中的防腐劑，也是刺激性最弱的防腐劑成分之一。
添加大劑量苯甲醇可使產品散發出近似花香的氣味，因為苯甲醇也是一些精油如茉莉花精油的芳香物質之一。
作為一種揮發性醇類，當苯甲醇用量較多時會造成皮膚刺激，但它用於化妝品仍然被視為安全的。

【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).
