HPF8 is the most controlled perfluoro-n-octane on the market. Chemical tests of Nuclear Magnetic Resonance (NMR), Fourier Transform Infrared Spectroscopy (FT-IR) and Gas Chromatography (GC) are performed to ensure its safety. The Hvalue is less than 10 ppm and the perfluorooctanoic acid (PFOA) is absent.
Biological tests of cytotoxicity by direct contact according to ISO 10993-5 are also performed on BALB 3T3 and ARPE-19 cells.
To increase safety, HPF8 was also tested for cytotoxicity in an innovative ex-vivo human retina model.
