PFOS
PFOS
Formerly known as REACH Annex XVII & Directive 2006/122/EC
Where would I Find It?
This was used in the production of certain stain repellent and water repellent finishes for textiles and leather. The use of branded products based on PFOS chemistry has been largely phased out in the textiles, paper and general clothing industries. However, non-branded products may still be produced.
Why is It a Problem?
PFOS is regarded as a "Persistent Organic Pollutant" (POP), which means it is bio-accumulative. It is toxic to the environment and to human health, and is considered to be reprotoxic.
What does the EU Directive Say?
It is banned in textiles or coated materials at concentrations greater than 1μg/m2.
How do I Test for It?
As yet, no official test method exists; CEN technical committees are currently developing a test method, expected to be published as CEN/TS 15968.
Can I Use Anything Else?
According to the EU Directive, perfluorooctanoic acid (PFOA) is suspected to have a similar risk profile to PFOS but risk assessments of it continue and it is not yet subject to any restrictions in the EU.
Brands such as "Teflon" are based on PFOA chemistry. The manufacturer of "Teflon" is participating fully in the risk assessments and Teflon continues to be widely used.
