Polymeric food contact materials
Are you aware that PFAS & PFCA restrictions will have huge impact on your business?
Chances are that your product contains PFAS and PFCA! Restrictions are already in place. Some additional restrictions will come into effect early next year. PFAS are used in a wide variety of consumer products because of their unique chemical and physical properties. Examples of these properties are oil and water repellence, temperature and chemical resistance, and surfactant properties. PFAS are used in many products, e.g. firefighting foams, non-stick metal coatings for frying pans, paper food packaging, creams and cosmetics, textiles for furniture and clothing, paints, coating, varnishes, chrome plating and preservatives. Check if your products are affected!
What are poly- and perfluoroalkyl substances (PFAS)?
PFAS stands for poly- and perfluoroalkyl substances. This is a large family of chemical substances which comprises more than 6,000 substances. PFAS are controversial because they are hazardous for human health and the environment. Due to new scientific insights certain chemicals belonging to the PFAS family are included in the REACH candidate list for authorisation as a SVHC.
What are Perfluoroalkyl carboxylic acids (PFCAs)?
Perfluoroalkyl carboxylic acids (PFCAs), or perfluorocarboxylic acids consist of a wide variety of substances.
Around 200 PFCAs are also belonging to the PFAS family. E.g. PFOA and PFNA are both a PFAS and a PFCA.
A certain amount of the PFCA precursor will remain as a residue in the final PFAS.
So if your product is coated or treated with a PHAS, it will also contain a PFCA.
There are thousands of PFCA-substances with a certain similar chemical composition that may be present in your products. Products that you place on the market after February 25, 2023 may not contain any of those PFCAs. This is regulated in the REACH restriction list under entry 68.
Six PFCAs are also listed in the REACH candidate list as a SVHC;
- Perfluorononan-1-oic acid (PFNA)
- Nonadecafluorodecanoic acid (PFDA)
- Henicosafluoroundecanoic acid (PFUnDA)
- Tricosafluorododecanoic acid (PFDoDA)
- Pentacosafluorotridecanoic acid (PFTrDA)
- Heptacosafluorotetradecanoic acid (PFTDA)
Alternatives for PFAS
Although all PFAS are controversial are not all PFAS substances restricted. It is expected that more and more PFAS substances will be added to the REACH candidate list in the near future. Seeking for PFAS alternatives is a must. You can divide the PFAS applications in consumer products in three major categories.
- Non-essential (deceptive marketing - mainly used in cosmetics)
- Essential for which alternative PFAS substances have not yet been developed.
Most PFAS substances in your consumer products will belong to category 2. Teflon (PTFE) is a typical example of a PFAS for which exist many alternatives.
