針對產品之抗油脂氧化成份,添加過量易引起皮膚過敏[2]。

多少為過量
BHT的負面資訊大多是來自於百分之百濃度的BHT,而且口服BHT才可能造成的人體的傷害,BHT主要作為食品的防腐劑及包裝材料,像是餅乾的包裝袋等,雖然服用高濃度的BHT可能會致癌,但是塗抹在皮膚上並不會造成敏感,因此在敏感性皮膚適用的產品中經常可以找到BHT,BHT在保養品及化妝品中的含量並不會有致癌的風險,它們在保養品的化妝品的濃度通常少於0.1%,BHT雖然會被皮膚吸收,但是並不會進入到血流裡,簡單地說,並不需要避免含有BHT的產品,這是在化妝品成分審核委員會(Cosmetic Ingredient Review Board)裡經過很多科學家和毒物專家證實的
凡士林的三重精煉凝膠,主要成分裡面有BHT耶!!!
可是大家都說很好用,甚至還有醫生推薦...
所以到底是要用還是不用?
上面不是有人解釋了BHT可以用在護膚品上麼,不要吃就好啦,而且在護膚品裏的含量是很少的
可是也不知道bht的含量有多少
所以加1%或是50%真的就差很多.....
台灣官員也不會去審查含量多少基本上是管制松散的
在台灣買化妝品真的得處處小心...
尤其是容易過敏皮膚的人
根本不想冒這種可能會怎樣的風險
ps:台灣政府應該多多學習德國管制化粧保養品的方式

豬油膏裏也有,不過含量應該很少吧
有的人真是腦子有病的樣子,
怕東怕西,乾脆什麼都別用了唄~
還有人擔心廠商會添加50%的BHT。。。
腦子有問題啊,防腐劑不要錢?如果添加過量造成大量使用者過敏,廠商才最倒黴好吧!再說進口品牌,原產國都會審查,你操什麼心。。。
真不知道這人的腦回路是什麼樣的。。。
能不要就不要用....還是有安全上的疑慮,保養品每天擦每天都接觸....

Butylated hydroxytoluene, a potent synthetic antioxidant that also has health concerns when consumed orally. The amount of BHT uses in cosmetic products is typically 0.01-0.1%, and does not pose a risk to skin, nor does it penetrate skin far enough to be absorbed into the bloodstream.

BHT isn't the worst, but there are simply more effective preservatives out there.

非常讚同Samantha_W的觀點~ 所以一直在努力尋找精簡健康而有效的小眾護膚品(畢竟大牌老牌的配方安全性往往令人失望)...
那Dior的粉漾潤唇膏有呢...擦嘴唇會吃到,這樣安全嗎?
It's the acronym for Butylated Hydroxy Toluene. It's a common synthetic antioxidant that's used as a preservative.
There is some controversy around BHT. It's not a new ingredient, it has been used both as a food and cosmetics additive since the 1970s. Plenty of studies tried to examine if it's a carcinogen or not. This Truth in Aging article details the situation and also writes that all these studies examine BHT when taken orally.
As for cosmetics, the CIR (Cosmetic Ingredient Review) concluded that the amount of BHT used in cosmetic products is low (usually around 0.01-0.1%), it does not penetrate skin far enough to be absorbed into the bloodstream and it is safe to use in cosmetics.
