Lanphos TEP 4 is a phosphate ester manufactured using polyphosphoric acid, leading to a product consisting predominantly of mono-esters. Its key advantage over conventional anionics is its excellent stability in high concentrations of acid, alkali, and electrolyte. Supplied in acid form, it can be neutralized with various bases to produce a salt. Lanphos TEP4 provides good wetting, detergency, lubricity, and emulsification properties.
