Methyl methacrylate is a monomer of polymethyl methacrylate. Polymethyl methacrylate is used in tableware and cooking utensils because it is highly transparent, light, acid and alkali resistant.
Unreacted monomers may remain in the material during polymethacrylic acid synthesis, the accepted concentration of eluted methyl methacrylate in the dissolution test is defined as 15 μg/mL or less in the sanitary test.

In this application, an aqueous ethanol solution was used to extract a commercially available plastic methacrylic resin container and measured. A standard additive was also measured.
