Restriction

Perfluorooctanoic acid (PFOA), its salts and PFOA-related substances

By Little Pro on 2017-06-19 Views:  Update:2017-06-19

Perfluorooctanoic acid (PFOA), its salts and PFOA-related substances are added to REACH annex XVII restricted substances list (entry 68) by Commission Regulation (EU) 2017/1000 on 14 June 2017. They are restricted in a significant number of consumer products such as apparel, textile products, inks and medical devices.

What are PFOA and PFOA-related Substances

Perfluorooctanoic acid (‘PFOA’), its salts and PFOA-related substances have some specific properties such as high friction resistance, dielectricality, resistance to heat and chemical agents, and low surface energy. They are used in a wide variety of applications such as in the fluoropolymer and fluoroelastomer production, as surfactants in fire-fighting foams, and in textile and paper production to provide water, grease, oil and/or dirt repellency. 

PFOA is identified as a persistent, bioaccumulative and toxic substance (‘PBT’) and was included in the Candidate List of Substances of Very High Concern (‘SVHC’) in 2013.  PFOA-related substances are substances that, based on their molecular structure, are considered to have the potential to degrade or be transformed to PFOA

Conditions of Restriction for PFOA and PFOA-related Substances

The table below summarizes the restriction conditions for PFOA, its salts and PFOA-related substances in REACH Annex XVII.

Entry Requirements and Exemptions

68. Perfluorooctanoic acid (PFOA) CAS No 335-67-1 EC No 206-397-9 and its salts.

Any related substance (including its salts and polymers) having a linear or branched perfluoroheptyl group with the formula C7F15- directly attached to another carbon atom, as one of the structural elements. Any related substance (including its salts and polymers) having a linear or branched perfluorooctyl group with the formula C8F17- as one of the structural elements.

The following substances are excluded from this designation: — C8F17-X, where X = F, Cl, Br. — C8F17-C(=O)OH, C8F17-C(=O)O-X′ or C8F17-CF2-X′ (where X′ = any group, including salts).

1. Shall not be manufactured, or placed on the market as substances on their own from 4 July 2020.

2. Shall not, from 4 July 2020, be used in the production of, or placed on the market in:

(a) another substance, as a constituent;

(b) a mixture;

(c) an article, in a concentration equal to or above 25 ppb of PFOA including its salts or 1000 ppb of one or a combination of PFOA-related substances.

3. Points 1 and 2 shall apply from:

(a) 4 July 2022 to: (i) equipment used to manufacture semi-conductors; (ii) latex printing inks.

(b) 4 July 2023 to: (i) textiles for the protection of workers from risks to their health and safety; (ii) membranes intended for use in medical textiles, filtration in water treatment, production processes and effluent treatment; (iii) plasma nano-coatings.

(c) 4 July 2032 to medical devices other than implantable medical devices within the scope of Directive 93/42/EEC.

4. Points 1 and 2 shall not apply to any of the following: (a) perfluorooctane sulfonic acid and its derivatives, which are listed in Part A of Annex I to Regulation (EC) No 850/2004;

(b) the manufacture of a substance where this occurs as an unavoidable by-product of the manufacture of fluorochemicals with a carbon chain equal to or shorter than 6 atoms;

(c) a substance that is to be used, or is used as a transported isolated intermediate, provided that the conditions in points (a) to (f) of Article 18(4) of this Regulation are met; (d) a substance, constituent of another substance or mixture that is to be used, or is used: (i) in the production of implantable medical devices within the scope of Directive 93/42/EEC; (ii) in photographic coatings applied to films, papers or printing plates; (iii) in photo-lithography processes for semiconductors or in etching processes for compound semiconductors; (e) concentrated fire-fighting foam mixtures that were placed on the market before 4 July 2020 and are to be used, or are used in the production of other fire-fighting foam mixtures.

5. Point 2(b) shall not apply to fire-fighting foam mixtures which were: (a) placed on the market before 4 July 2020; or (b) produced in accordance with point 4(e), provided that, where they are used for training purposes, emissions to the environment are minimised and effluents collected are safely disposed of.

6. Point 2(c) shall not apply to: (a) articles placed on the market before 4 July 2020; (b) implantable medical devices produced in accordance with point 4(d)(i); (c) articles coated with the photographic coatings referred to in point 4(d)(ii); (d) semiconductors or compound semiconductors referred to in point 4(d)(iii).’
