ABSTRACT:
A cleaning solvent having an extended shelf life includes ethylene dipropionate, and at least one alicyclic carbonate, preferably propylene carbonate, with or without other additives. Typically additives include triethanolamine (TEA) and N-methyl-2-pyrrolidone (NMP). The solvents may be diluted with water for cleaning tasks where control of corrosion is not an important consideration.
