Technical guides on additive chemistry across lubricants, fuels, metalworking fluids, oilfield chemicals, and more.
Calcium sulfonate and calcium phenate are the two workhorse overbased detergents in engine oils. The difference sits in the polar head: sulfonates…
Detergents neutralise acids; dispersants suspend soot. Both are essential engine oil additives — but they do different jobs. This guide explains the…
ZDDP (zinc dialkyldithiophosphate) is the most widely used antiwear additive in engine oil. Learn how it works, why phosphorus limits matter, and…
Anti-wear (AW) additives protect metal surfaces under moderate loads by forming sacrificial, phosphate-rich boundary films — zinc dialkyldithiophosphate (ZDDP) is the classic…
A demulsifier additive is a surface-active additive that forces emulsified water to separate out of oil. The name says what it does…
