AKYPO[R] LF2 is a co-surfactant for general metal cleaners which is pH and hard water stable with hydrotropic and anti-corrosion properties. Compatible with quaternary compounds, it is peroxide-stable, hydrolysis-stable, hypochlorite-stable, alkaline- and acid-stable. AKYPO[R] LF types are used singly or in combination as low-foaming surfactants for application in industrial areas. In acidic or aqueous solutions, the AKYPO[R] LF types behave like non-ionic surfactants. In neutralised form they behave like anionic surfactants (this is the so-called crypto-anionic character of alkyl ether carboxylic acids).
