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
