Synthetic
Not Clean
OriginDerived from methacrylic acid and lauryl alcohol, both synthetic organic compounds from petroleum feedstocks. Synthesized through esterification reaction between methacrylic acid and lauryl alcohol using acid catalysts.
Based on available data, the CIR Expert Panel concluded that ... Lauryl Methacrylate is safe as used in nail enhancement products when skin contact is avoided. Products containing these ingredients should be accompanied with directions to avoid skin contact, because of the sensitizing potential of Methacrylates.
