Abstract
Compositions prepared from an adduct of mono-maleated polyunsaturated vegetable oil and an alcohol mixture comprising a hydrophobic alcohol having at least 9 carbon atoms and methoxypolyethylene glycol having a number average molecular weight (Mn) of at least 350. Metalworking fluids comprising less than 3 wt % of a composition that is an adduct of mono-maleated polyunsaturated vegetable oil and an alcohol mixture comprising an alcohol having at least 2 carbon atoms and methoxypolyethylene glycol having a number average molecular weight (Mn) of at least 350. Methods of improving the stability and/or lubricity of a metalworking fluid using a composition that is adduct of mono-maleated polyunsaturated vegetable oil and an alcohol mixture comprising an alcohol having at least 2 carbon atoms and methoxypolyethylene glycol having a number average molecular weight (Mn) of at least 350.
