PTFE/Polyperfluoromethylisopropyl Ether — confirmed in investigation
What is PTFE/Polyperfluoromethylisopropyl Ether — confirmed in investigation?
PTFE, or Polytetrafluoroethylene, is a synthetic fluoropolymer of tetrafluoroethylene. It is commonly known for its use in nonstick coatings for cookware and as a lubricant in industrial applications. This compound is produced through the polymerization of tetrafluoroethylene.
In cosmetic and personal care products, PTFE is often used for its ability to create a smooth, glide-on texture, particularly in makeup products like foundation and eye pencils. However, concerns have been raised about the potential release of perfluorooctanoic acid (PFOA), a chemical sometimes used in PTFE processing, which has been linked to health concerns.
When encountering PTFE on a label, it's important to note that while it is widely used across various industries, its safety in cosmetics involves understanding its potential impurity content and the regulations around these impurities.
Commonly found in: Makeup, Eyeliners, Foundations, Skincare applications, Industrial applications
What to watch
- PTFE can contain residual PFOA, which has been associated with health concerns.
- The long-term safety of PTFE in cosmetics has not been fully established.
Benefits
- PTFE provides a smooth application in cosmetic products.
The FDA regulates PTFE for use in specific applications, with guidelines on allowable levels of impurities like PFOA.
Research indicates PTFE itself is stable, but concerns about impurities such as PFOA persist.
PTFE is a synthetic compound and is considered vegan.

Scout's take
PFAS forever chemical variant confirmed through investigation. Polyperfluoromethylisopropyl ether shares the same environmental persistence and bioaccumulation concerns as PTFE. Applied near eyes.
