Abstract

2-Ethylhexyl esters of fatty acids, optionally mixed with emulsifiers, solubilizers, corrosion inhibitors, and/or water, are useful as low viscosity agents for the cold cleaning of metal surfaces contaminated mainly with oil. Such agents are non-toxic when inhaled and completely biodegradable.
