Phosphate esters

The range of phosphate esters contains not only free acid phosphate esters but also neutralised versions. Phosphate esters are based on alcohols, aromatic ethoxylates or alcohol ethoxylates. These 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. Phosphate esters 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 range may be selected to perform a range of functions including:
• Detergency
• Emulsification
• Foaming
• Dispersing
• Wetting
• Antifoaming

Products in our range 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 phosphate ester of choice for use in:
• Alkaline Detergents
• Metal Working Fluids
• Emulsion Polymerisation
• Agricultural Formulations
