Perfluorohexane (C 6 F 14), or tetradecafluorohexane, is a fluorocarbon.It is a derivative of hexane in which all the hydrogen atoms are replaced by fluorine atoms. It is used in one formulation of the electronic cooling liquid/insulator Fluorinert for low-temperature applications due to its low boiling point of 56 °C and freezing point of −90 °C.
Perfluorohexanesulfonic acid (PFHxS) (conjugate base perfluorohexanesulfonate) is a synthetic chemical compound.It is one of many compounds collectively known as per- and polyfluoroalkyl substances (PFASs).

The process proceeds at low voltage (5 – 6 V) so that free fluorine is not liberated. The choice of substrate is restricted as ideally it should be soluble in hydrogen fluoride. Ethers and tertiary amines are typically employed. To make perfluorohexane, trihexylamine is used, for example: N(C 6 H 13) 3 + 45 HF → 3 C 6 F 14 + NF 3 + 42 H 2
The International Nomenclature of Cosmetic Ingredients (INCI) are the unique identifiers for cosmetic ingredients such as waxes, oils, pigments, and other chemicals that are assigned in accordance with rules established by the Personal Care Products Council (PCPC), previously the Cosmetic, Toiletry, and Fragrance Association (CTFA).

Perfluorohexane is used for low-temperature heat-transfer applications due to its 56 °C (133 °F) boiling point. Another example is FC-75 , perfluoro(2-butyl-tetrahydrofurane). There are 3M fluids that can handle up to 215 °C (419 °F), such as FC-70 ( perfluorotripentylamine ).
In 2021, Senators Susan Collins of Maine and Richard Blumenthal of Connecticut proposed the No PFAS in Cosmetics Act in the United States Senate. [137] It was also introduced in the United States House of Representatives by Michigan Representative Debbie Dingell, [138] but the Republican Party, supported by the U.S. chemical industry ...
