Information Express | EU Passes Proposal on Restriction of Perfluorohexanoic Acid (PFHxA), Its Salts and Related Substances

On February 29th, 2024, the Commission of EU REACH voted to pass a proposal to restrict perfluorocaproic acid (PFHxA), its salts and related substances in Appendix XVII of REACH ((EC) No.1907/2006).

Material information

"Perfluorohexanoic acid (PFHxA) and its salts and PFHxA-related substances" refers to:

★ Compounds containing linear or branched C₅F₁₁- perfluoropentyl groups linked to carbon atoms;

★ Containing straight chain or branched chain C₆F₁₃- perfluorohexyl

Excluding the following substances:

★C₆F₁₄

★C₆F₁₃-C(=O)OH, C₆F₁₃-C(=O)O-X′ or C₆F₁₃-CF₂-X′(where X′ = any group, including salt);

★ A substance containing a perfluoroalkyl group C₆F₁₃- an oxygen atom directly connected to a non-terminal carbon atom.

Limit requirements

In homogeneous materials:

★ The sum of PFHxA and its salts is less than ＜0.025mg/kg (25ppb).

★ The sum of related substances of PFHXA is less than 1 mg/kg (1000 ppb).

Scope of control and its effective time

Warm tips

EU REACH regulations are becoming stricter, and enterprises are facing more and more control requirements. ZRLK suggested that relevant enterprises should investigate the compliance of perfluorinated substances in products as soon as possible in combination with the control of laws and regulations, so as to ensure that the products put on the market meet the control requirements of laws and regulations and avoid economic losses caused by violations after the products are put on the market. Our company has a professional technical team and rich experience in product testing, which can help you easily understand whether the products are safe and compliant.
