No. Cocofloss is made without intentionally added PFAS (per- and polyfluoroalkyl substances) — a class of synthetic fluorinated chemicals sometimes used in dental floss to enhance glide. Instead, Cocofloss is woven from recycled polyester sourced from post-consumer water bottles, and coated with wax and coconut oil, providing a smooth, effective clean without relying on PFAS- or PTFE-based coatings.
We take this seriously and test for PFAS. Our materials are regularly screened and tested by a third-party ISO-accredited lab — TÜV Rheinland — to ensure they meet strict safety and regulatory standards, including testing for known PFAS compounds. “ISO-accredited” means TÜV Rheinland's testing and certification services are recognized internationally for their competence and impartiality. Cocofloss also meets Commission Regulation (EU) No 10/2011, a European Union (EU) regulation that sets safety requirements for plastic materials and articles that come into contact with food. We maintain close relationships with our suppliers to uphold traceability throughout our manufacturing process, and always test for PFAS at the end of production.
There are many routes for PFAS into the environment— for example, firefighting foam can be directly released into the environment, or household cleaning products and cosmetics containing PFAS can be washed down the drain and indirectly enter the environment. Your non-stick pan? Probably PFAS. Your waterproof coat? Possibly PFAS. Your greaseproof paper? PFAS. Because PFAS are fairly ubiquitous in the environment at large, Cocofloss is produced in a facility where PFAS may be present.
As part of our ongoing commitment to Conscious Innovation, we continue to monitor the evolving science around PFAS and other environmental toxins to ensure Cocofloss remains good for you — and better for the planet.
