Perfluoroalkyl Acids

Description

Colorless liquid with an unpleasant odor; [MSDSonline]

Sources/Uses

Perfluorocarboxylic acids include Perfluoroacetic, Perfluoropropionic, Perfluorobutyric, Perfluorovaleric, Perfluorocaproic, Perfluoroheptanoic, Perfluorocaprylic, Perfluorononanoic, Perfluorocapric, Perfluoroundecanoic, and Perfluorododecanoic acid; These long-chain perfluoroalkanecarboxylic acids and their salts are used as wetting, dispersing, emulsifying, and foaming agents. They greatly reduce surface tension in aqueous solutions. [Ullmann]
