Libraphos – Market Leading Phosphate Esters

About Libraphos

Phosphate esters are based on alcohols, aromatic ethoxylates or alcohol ethoxylates. The Libraphos series of free-acid phosphate esters from Libra Speciality Chemicals are anionic surfactants, suitable for use in a wide range of applications and industries. The Libraphos series of free acid phosphate esters are 100% active anionic surfactants.

Libraphos phosphate esters are manufactured by either a polyphosphoric acid route giving predominantly mono esters or by a phosphorous pentoxide route to give predominantly di-esters. These phosphate esters can then be neutralised to achieve a variety of salts. The Libraphos series of surfactants may be used in several applications due to their stability at high temperatures or in acidic or alkaline conditions. These attributes offer significant advantages over other surfactants.
