The French National Assembly on Thursday unanimously adopted a bill aimed at restricting the manufacture and sale of products containing per- and polyfluoroalkyl substances — also known as PFAS or “forever chemicals.” The MPs, backed by the government, voted to exclude kitchen utensils from the scope of the text.
Thanks to an intense lobbying push, manufacturers of frying pans and saucepans — including the SEB group, which owns Tefal — are exempt from this ban under the proposed law penned by French Green MPs.
Majority groups initially tried to delay the ban on kitchen utensils until 2030 — a timetable refused by the French Green MPs who instead suggested an exemption until 2026.
Could you not re-oil the pan like you do with steel and iron pans?
Unfortunately not as the oil is impregnated into very small pores during manufacturing. This is the “sol-gel” part of the process, a way of creating a solid and liquid in very close contact.
The oil is effectively bonded to the surface creating a “permanent oil film” which is why it works so well. You can think of the long tails of the silicone molecules being trapped in the pores.
However once they escape there’s no putting them back. Seasoning cast iron is a totally different process involving polymerizing light oils into a solid coating.
