致敏
26種被歐盟規範禁用的化妝品添加香料。

不是禁用,是要註明: 根據歐盟對產品標籤的法例規定,Benzyl Alcohol等25種香氛成份在超出指定含量時便要列明在產品標籤上
9成歐洲比較大的天然品牌都有類似香料成份作為抗菌防腐,怎麼可能禁用呢?而且做抗菌防腐的含量都很低,比起化學防腐好很多!
而且化妝品不可能不防腐,滋生細菌更可怕。
This fragrance ingredient has a very fun name, but it can be irritating to skin.
Unfortunately, linalool can be a problematic ingredient for some people. When linalool comes into contact with oxygen, it breaks down and becomes oxidized, which can cause an allergic reaction. Manufacturers do include other substances in the products to delay this oxidation process, but allergenic substances can still be formed from linalool when it is stored.
Dermatologist Johanna Bråred Christensson explains, “One way of trying to minimize exposure to oxidized linalool is to avoid buying large packs of soap and shower cream, and always to replace the top after using a bottle.”
In conclusion, the safety of linalool depends on whether this ingredient is used in its natural form or as a synthetic fragrance. Linalool as a natural compound of an organic essential oil may provide anti-inflammatory effects, but the synthetic version can possibly lead to skin irritation or allergic reactions.

別看到香料兩個字就害怕,這東西是好東西
真實薰衣草精油成分中最高含量就是這東西,害怕的人可以上網GOOGLE一下這東西的功效
這個別稱叫"薰衣草醇"是不是看起來瞬間就友善了許多?
這成分可以鎮靜中樞神經系統,驅蟲,降體溫,助眠
就算是純天然的東西對人體都可能是會致敏了,更何況是精煉出來濃度更高的呢?
歐盟這次發布的25項幾乎都是常見的精油內所含的物質
因為在歐洲國家對於精油的規範是很嚴格的,例如在法國甚至是由藥師或醫師開立處方來治病的
包括我們日常中最常看見的檸檬烯,沒錯,就是柑橘類幾乎都會有的物質(很多非柑橘類的植物其實也有)
但你不會因為有人對這個會過敏就從此不吃柑橘類水果吧?
linalool(芳樟醇)
薰衣草的芳香性成分,接觸到空氣後,芳樟醇很容易造成皮膚過敏和皮膚刺激 (出處: Contact Dermatitis, January 2008, pages 9-14; May 2002, pages 267–272, and June 2005, pages 320–328),目前的研究發現芳樟醇對於皮膚細胞具有毒性 (出處: Cell Proliferation, June 2004, pages 221-229)。
