The Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) legislation in Europe has limited the use of certain materials in the manufacturing of tattoo inks; in particular, Pigment Blue 15:3 and Pigment Green 7 have been banned for the use in tattoo inks and permanent makeups and all labels must include an accurate list of ingredients. This study analyzed green and blue inks from five different manufacturers distributed to the European market, all of which claim to be REACH compliant. Nine out of ten inks analyzed were found to not be compliant and four contained banned material. The polymorph of Pigment Blue 15 found in four inks was unable to be determined. The majority of inks showed labeling inaccuracies, including the addition of unlisted poly(ethylene glycol) and propylene glycol. This study highlights issues around REACH compliance of tattoo inks on the European market and the need for manufacturing protocols to ensure accurate labeling.

分析符合 REACH 标准的蓝色和绿色纹身油墨


欧洲的化学品注册、评估、授权和限制 （REACH） 立法限制了某些材料在纹身墨水制造中的使用;特别是，Pigment Blue 15：3 和 Pigment Green 7 已被禁止用于纹身墨水和永久化妆品，并且所有标签都必须包含准确的成分列表。本研究分析了分销到欧洲市场的五家不同制造商的绿色和蓝色油墨，所有这些制造商都声称符合 REACH 标准。在分析的 10 种油墨中，有 9 种被发现不合规，4 种含有违禁材料。无法确定在四种墨水中发现的 Pigment Blue 15 的多晶型物。大多数油墨的标签不准确，包括添加了未列出的聚乙二醇和丙二醇。本研究强调了欧洲市场上纹身油墨的 REACH 合规性问题，以及需要制定生产协议以确保准确标签。
