Lanphos PET33
Product Category: Anionics
Polyaryl Phenyl Ether Phosphate – Triethanolamine Salt
Lanphos PET33 is a phosphate ester manufactured using phosphorous pentoxide to give a product that contains both mono and di-esters. The main advantage of a phosphate ester over a conventional anionic is excellent stability in high concentration of acid, alkali and electrolyte.
