Abstract
A method for identifying methyl methacrylate (MMA) in the liquid part of a liquid/powder system used to form artificial finger nails and toenails. The chemistry used to identify MMA in liquid monomers provides an accurate and inexpensive way to monitor the use of MMA in liquid monomers in violation of a ban of MMA by the Food and Drug Administration (FDA) for purposes of creating artificial finger nails and toenails.
