PERFLUOROMETHYLCYCLOPENTANE.

Avoid CAS 1805-22-7 / SKIN CONDITIONING, SOLVENT

Perfluoromethylcyclopentane is an inert perfluorocarbon employed in cosmetic formulations as a solvent and skin conditioning agent. It helps to deliver a lightweight, non-greasy product feel and enhances spreadability by forming a temporary surface film.

Cosmetic solvent Skin conditioning agent

Science

As a chemically inert, non-polar perfluorocarbon, Perfluoromethylcyclopentane functions by creating a temporary, ultra-thin film on the skin. This mechanism facilitates its role as a solvent, improves formulation spreadability, and contributes to a desirable lightweight, non-greasy skin feel.

Safety

CIR Status
Insufficient data
Sensitization risk High

Perfluoromethylcyclopentane is classified as a per- and polyfluoroalkyl substance (PFAS). GHS warnings indicate it is harmful if swallowed (H302), causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335). PFAS compounds are generally associated with significant concerns including environmental persistence, bioaccumulation, immunotoxicity, developmental and reproductive toxicity, and potential links to cancer, thyroid disruption, and liver effects.

Our Assessment

Avoid

Due to its classification as a PFAS, documented potential for skin and eye irritation, and broad concerns regarding persistence, bioaccumulation, and systemic toxicity, Perfluoromethylcyclopentane is not recommended for inclusion in skincare formulations.
