PTFE (Polytetrafluoroethylene) — 5th ingredient
What is PTFE (Polytetrafluoroethylene) — 5th ingredient?
Polytetrafluoroethylene, commonly known as PTFE, is a synthetic polymer made up of carbon and fluorine. It is best known for its use in non-stick cookware coatings and other industrial applications due to its high resistance to heat and chemical reactions.
In the context of cosmetics, PTFE may be used as a film-forming agent, helping in smooth application and providing water resistant properties. However, its safety profile in personal care products is debated, as manufacturing processes can sometimes leave behind residual compounds that are of concern.
When you see PTFE on a label, it's important to consider its intended use and the context, particularly given that it is not intended for ingestion and your safety concerns may vary compared to industrial or cooking uses.
Commonly found in: Makeup, Skincare Products, Industrial Coatings, Non-Stick Cookware, Fabric Treatments
What to watch
- Concerns have been raised about the potential presence of residual processing chemicals in PTFE.
The FDA does not approve PTFE for food uses other than some indirect applications, with caution around potential contamination.
Research shows PTFE itself is largely inert, but potential contaminants in its production process are a health concern.
PTFE is a synthetic chemical, not derived from animals, and generally considered vegan.
Scout's take
PFAS forever chemical at high concentration in a daily concealer. Applied to thin under-eye skin where absorption rates are highest. PTFE does not break down in the body or environment.
