DEG Monooleate Corrosion Inhibitor for Metalworking
Diethylene glycol monooleate (DEG monooleate) is a non-ionic ester surfactant used as a mild corrosion inhibitor, emulsifier, and lubricity additive in water-based metalworking fluids. Its dual hydrophilic-lipophilic structure adsorbs onto metal surfaces while maintaining miscibility with water, providing effective ferrous corrosion protection in diluted cutting fluids. DEG monooleate also acts as a coupling agent to improve compatibility between the oil and water phases in semi-synthetic fluids.
