It’s a smart question — and yes, PFAS can potentially be introduced during high-heat recycling processes, especially if the original plastic included fluorinated additives. When plastics are melted and reprocessed, there’s a possibility that trace PFAS compounds can form or persist, depending on how the materials were treated in their first life.
That’s why at COCOLAB, we’re extra careful. We source recycled materials — like the recycled polyester used in our Cocofloss fibers and recycled plastic in our Cocobrush handles — from trusted partners who meet strict environmental and safety standards. Our materials are routinely tested after production by an ISO-accredited lab, TÜV Rheinland, to ensure they are free from intentionally added PFAS and other unwanted substances. Their testing methods align with international regulations, ensuring that our products meet stringent safety criteria. We also conduct screenings of our final products to confirm they meet our Conscious Innovation standards — good for you and better for the planet.
