Sulfonates Sodium petroleum sulfonate

Dewox 72®

Sodium petroleum sulfonate. Emulsifier base for soluble and semi-synthetic metalworking fluids.

A soluble sodium petroleum sulfonate used as an emulsifier and rust inhibitor in soluble and semi-synthetic metalworking fluids, and as a corrosion inhibitor in rust-preventive process oils.

Overview

Dewox 72 is a sodium petroleum sulfonate carried in refined mineral oil. It is a workhorse emulsifier for water-miscible metalworking fluids and a soluble rust inhibitor for protective process oils.

In soluble and semi-synthetic coolants it builds and stabilizes the emulsion while protecting freshly machined ferrous surfaces. In straight oils it contributes water-displacing corrosion protection.

Chemistry: Sodium petroleum sulfonate in refined mineral oil.

Applications

  • Emulsifier for soluble and semi-synthetic metalworking fluids
  • Rust inhibitor in rust-preventive process oils
