Documented Uses

• Used as a surfactant; [HSDB] Used mainly as a processing aid in the manufacture of fluoropolymers; Also as a lubricating oil additive, surfactant for fire extinguishers, cleaning agent, textile finishing agent, polishing surfactant, and in liquid crystal display panels; [ExPub: ECHA - Proposal for Harmonised Classification and Labelling]
• Textiles (Printing, Dyeing, or Finishing) [Category: Industry]
• Long-chain perfluoroalkanecarboxylic acids and their salts are surface-active chemicals (surfactants), which greatly reduce the surface tension (surface energy) of water, aqueous solutions, and organic liquids even at low concentrations. These acids (C6- C12) and derivatives are used as wetting, dispersing, emulsifying, and foaming agents. /Long-chain perfluoroalkanecarboxylic acids/
