 The three major products are ethylene glycol monoethyl ether acetate (EEA), ethylene glycol monobutyl ether acetate (EBA), and propylene glycol monomethyl ether acetate (PMA, more commonly known as PGMEA in semiconductor manufacturing processes, where it is used as a resist solvent).This application consumes about 15% to 20% of worldwide acetic acid.Ether acetates, for example EEA, have been shown to be harmful to human reproduction.
