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
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。
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.
