General description

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.

Application

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.

Allergic contact dermatitis is common and can be prevented. The relationship between thresholds for patch tests and the repeated open application test (ROAT) is unclear. It would be desirable if patch test and ROAT data from already sensitized individuals could

Although genetic factors probably account for differences in susceptibility to contact allergy, they have not yet been identified, partly due to an insufficient understanding of 'susceptibility'. Regarding polysensitization (PS) as a sign of increased susceptibility, we studied the relationship between
