Lanphos PET22 is a phosphate ester manufactured using phosphorous pentoxide, resulting in a product containing both mono- and di-esters. The primary advantage of this phosphate ester over conventional anionics lies in its excellent stability in high concentrations of acid, alkali, and electrolyte. This product offers good wetting and dispersion properties for pigments and agrochemicals, both when used alone and in combination with nonionic surfactants.
