以往均是做為解熱鎮痛的acetaminophen作為雙氧水的賦形劑

他的賦形劑濃度是0.05%，作為過氧化氫的安定劑使用

在染料工業上算是很常用的安定劑，由於acetaminophen無色、無味，相對無害，所以作為安定劑來說算是安全的選擇

As H₂O₂ stabilizer

Because of its H₂O₂ stabilizing property it is assumed that Acetaminophen occurs to some extent in cosmetic products wherein H₂O₂ is employed as an ingredient. The cosmetics then concerned would mainly be the oxidative hair coloring products the hair bleaching products and possibly also to some degree the tooth bleaching products.

Because of lack of data we in accordance with SCCS guidance apply the default it is present in every oxidative hair coloring / bleaching product currently being placed on the market in Europe.

The Codecheck database, mentions 13 hair coloring /hair bleaching products that according to the list of ingredients contain Acetaminophen. The molecule is together with hydrogen peroxide in

these products. These 13 products all contain 10 – 25 different ingredients each. The Acetanilide is mostly in the 9 list of ingredients of the developer- and we judge that the concentration is roughly of the same magnitude as that of two other structurally very similar H₂O₂ stabilizer Acetanilide and Phenacetin。

另外常用的過氧化氫安定劑還有acetanilide、phenacetin
