Perfluoroperhydrophenanthrene

What is Perfluoroperhydrophenanthrene?

Perfluoroperhydrophenanthrene is a synthetic, fully fluorinated cyclic hydrocarbon from the perfluorocarbon family. Chemically inert with high oxygen solubility, it originates from fluorochemical engineering processes. In cosmetics, it appears mainly in eye makeup removers and specialized cleansers targeting waterproof formulations. It works as a solvent by breaking down oil-based pigments and polymers through its low surface tension and density, enabling effortless glide and removal without mechanical friction. Simultaneously, it acts as a skin conditioner by forming a lightweight film that preserves moisture balance and enhances skin suppleness. Its non-volatile nature ensures clean rinse-off, leaving no greasy residue, and its biocompatibility supports use on delicate areas.
