Methoxyacetic acid is a derivative of acetic acid in which a hydrogen atom of the methyl group is replaced by a methoxy group. As indicated by the synonym methyl glycolic acid, and as the simplest ether carboxylic acid, methoxyacetic acid can be understood as a methyl ether of glycolic acid.
Due to its considerable reprotoxic potential, methoxyacetic acid has been adopted into the list of SVHC substances (substances of very high concern)[1] and is only registered as an intermediate product for industrial purposes under strictly controlled conditions.
For consumer applications, such as for the cleaning and decalcification of surfaces, the substance must be substituted by safe alternatives.
