REACH法规:旨在限制含有9至14个碳原子链的全氟羧酸,其盐类和相关物质已于2023年2月25日正式生效

REACH法规附件十七第68项旨在限制含有9至14个碳原子链的全氟羧酸(PFCA) (PFCA C9-C14),其盐类和相关物质已于2023年2月25日正式生效

这一新的限制要求企业不再将文本所涵盖的PFCA作为一种物质、混合物和物品在市场上销售,如果其质量浓度超过:

•C9-C14 PFCAs及其盐类的总和:25 ppb (0.025 mg/kg);

•C9-C14 PFCAs相关物的总和:260 ppb (0.260 mg/kg)。


此限制所涵盖的物质列在ECHA网站的问答(Q&A)页面上:

-PFNA (C9-PFCA, CAS No. 375-95-1)及其盐

-PFDA (C10-PFCA, CAS No. 335-76-2)及其盐

-PFUnDA (C11-PFCA, CAS No. 2058-94-8)及其盐

-PFDoDA (C12-PFCA, CAS No. 307-55-1)及其盐

-PFTrDA (C13-PFCA, CAS No 72629-94-8)及其盐

-PFTDA (C14-PFCA, CAS No. 376-06-7)及其盐;


以及根据其结构公式有可能降解或转化为C9-C14全氟羧酸的任何其他与PFCA有关的物质。

草案规定,从2023年7月4日起,对个人防护服(PPE)的“防水或防油纺织品”进行临时豁免。


PFCAs是PFAS(全氟烷基物质和多氟烷基物质)的一个子集,根据ECHA上个月公布的另一项限制草案,成员国也希望在欧洲完全限制其制造和使用。


Entry 68 of Annex XVII of the REACH Regulation which aims to restrict perfluorocarboxylic acids (PFCA) containing chains of 9 to 14 carbon atoms (PFCA C9-C14), their salts and related substances has officially entered into force February 25, 2023

This new restriction requires companies to no longer place on the market PFCAs covered by the text as a substance, in mixtures as well as in articles if their mass concentration exceeds:

·25 ppb (0.025 mg/kg) total of C9-C14 PFCAs and their salts;

·260 ppb (0.260 mg/kg) in sum of C9-C14 PFCA-related substances.


The substances covered by this restriction are listed on the Questions & Answers (Q&A) page of the ECHA website:

-PFNA (C9-PFCA, CAS No. 375-95-1) and its salts,

-PFDA (C10-PFCA, CAS No. 335-76-2) and its salts,

-PFUnDA (C11-PFCA, CAS No. 2058-94-8) and its salts,

-PFDoDA (C12-PFCA, CAS No. 307-55-1) and its salts,

-PFTrDA (C13-PFCA, CAS No 72629-94-8) and its salts,

-PFTDA (C14-PFCA, CAS No. 376-06-7) and its salts;


As well as any other PFCA-related substances which, according to their structural formulas, have the potential to degrade or transform into C9-C14 perfluorocarboxylic acids.


The text provides for some temporary exemptions for "water-repellent or oil-repellent textiles" for personal protective clothing (PPE), which will only be affected by this restriction from July 4, 2023.


PFCAs are a subset of PFAS (per- and polyfluoroalkyl substances) which Member States also want to completely restrict the manufacture and uses of in Europe under another draft restriction published by ECHA last month.
