Claims18
A method of removing oil and/or fat from an article, the method comprising applying a solvent to the article, which is an engine, a manufactured metal product, a furnace, and wherein the solvent comprises one or more alkyl esters of fatty acids having formula
- (I):
- RCOOR′
- and one or more esters of fatty acids of glycerol carbonate having formula (II):
- wherein:
- R represents a mono- or polyunsaturated, linear, branched or cyclic alkyl or alkenyl radical, containing from 4 to 24 carbon atoms;
- R′ represents a linear, branched or cyclic alkyl radical containing from 1 to 8 carbon atoms.
A method of removing grease from leather, the method comprising applying a solvent to the leather, wherein the solvent comprises one or more alkyl esters of fatty acids having formula
- (I):
- RCOOR′
- and one or more esters of fatty acids of glycerol carbonate having formula (II):
- wherein:
- R represents a mono- or polyunsaturated, linear, branched or cyclic alkyl or alkenyl radical, containing from 4 to 24 carbon atoms;

- (I):
- RCOOR′
- and one or more esters of fatty acids of glycerol carbonate having formula (II):
- wherein:
- R represents a mono- or polyunsaturated, linear, branched or cyclic alkyl or alkenyl radical, containing from 4 to 24 carbon atoms;
- R′ represents a linear, branched or cyclic alkyl radical containing from 1 to 8 carbon atoms.
A method of making an oil-based paint, the method comprising mixing a solvent with pigment, and wherein the solvent comprises one or more alkyl esters of fatty acids having formula
- (I):
- RCOOR′
- and one or more esters of fatty acids of glycerol carbonate having formula (II):
- wherein:
