Octadecylphosphonic acid Use and Manufacturing
Octadecylphosphonic acid is used as detergents, dispersants, emulsifiers, and chelating agents. Alkyl phosphonic acids are typically sparingly soluble in both organic solvents and water, but become more soluble in water when neutralized to phosphonates at neutral to high pH.
