Application

DL-Menthol may be used as an extraction solvent for the determination of parabens in food products, cosmetics and pharmaceuticals using liquid-liquid microextraction with high performance liquid chromatography-diode array detection (HPLC-DAD). It may also be used for the preparation of hydrophobic deep eutectic solvent (DES) in the extraction and determination of methylparaben, propylparaben, and butylparaben from cosmetics samples using syringe-to-syringe dispersive magnetic nanofluid microextraction procedure (SS-DMNF-ME) with high-performance liquid chromatography technique (HPLC).

General description

This reference material (RM) is produced and certified in accordance with ISO/IEC 17025. This RM is traceable to primary material from an NMI, e.g. NIST or NMIJ.

DL-Menthol, a cyclic terpene alcohol and a naturally occurring compound, originates from the plants of Mentha species. It has a typical minty smell, flavor and finds applications as an ingredient in fragrances, food products, and cosmetics including shower gels, shampoos, face creams, body lotions, liqueurs, candy, etc.
