Libraphos: Phosphate Esters

Libraphos: Phosphate Esters

The Libraphos series of free acid phosphate esters are 100% active anionic surfactants. Phosphate esters are based on alcohols, aromatic ethoxylates or alcohol ethoxylates.

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 a number of applications due to their stability at high temperatures or in acidic or alkaline conditions. These attributes offer significant advantages over other surfactants.

Products from the Libraphos Series may be selected to perform a range of functions including:

  • Detergency
  • Emulsification
  • Foaming
  • Dispersing
  • Wetting
  • Antifoaming

Products in the Libraphos series are designed to give a range of properties depending upon the hydrophobe, phosphation agent and molar ratios used.

These properties can determine the selection of the Libraphos products for use in:

  • Alkaline Detergents
  • Metal Working Fluids
  • Emulsion Polymerisation
  • Libraphos Antiwear
  • Agricultural Formulations
