一般描述
Methyldibromoglutaronitrile (MDBGN) is a bromine-containing preservative and a clinically significant allergen as investigated from animal/human clinical studies.
Methyldibromoglutaronitrile can be generally used as a preservative in the cosmetic industry for many skin care products.
应用
Methyldibromoglutaronitrile may be used as an analytical reference standard for the quantification of the analyte in cosmetic products using ultra performance liquid chromatography (UPLC) coupled to inductively coupled plasma mass spectrometry (ICP-MS) and gas chromatography followed by mass spectrometry technique.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
