Zinc dithiophosphate Wikipedia

Zinc dialkyldithiophosphates (often referred to as ZDDP) are a family of coordination compounds developed in the 1940s that feature zinc bound to the anion of a dialkyldithiophosphoric acid ( ammonium diethyl dithiophosphate) These uncharged compounds are not salts They are soluble in nonpolar solvents and the longer chain derivatives easily dissolve in mineral and synthetic oils used
