CI-301

Calcium alkylbenzene sulfonate (neutral)

The standard neutral sulfonate for oil-based rust preventives and hydraulic oils. Excellent water displacement, no TBN contribution — which is exactly what you want when TBN is not part of the specification.

The chemistry

Corrosion & Rust Inhibitors

Ferrous surface passivation and water displacement

Typical treat rate0.05 – 1.0 %

Neutral alkylbenzene sulfonates adsorb onto steel and physically exclude water from the surface. Neutral — as opposed to overbased — means they contribute rust protection without the acid-neutralising reserve, so they are used where TBN is not wanted.
