Description and Uses
1,2-Dibromo-2,4-dicyanobutane is the main sensitizer of Euxyl K400, a widely used preservative agent in cosmetics, toiletries or metalwork fluids.
Methyldibromo glutaronitrile (MDBGN), also known as dibromocyanobutane, is to be found in the preservative system Euxyl K 400 (also called Tektamer 38), which is a mix of MDBGN and phenoxyethanol in a ratio of 1:4. Euxyl K 400 is a broad‐spectrum preservative with activity against fungi and bacteria. MDBGN is nearly always the allergen when sensitization to Euxyl K 400 occurs.
1,2-Dibromo-2,4-dicyanobutane is a preservative for metalworking fluids, cosmetics, adhesives, latex emulsions and paints, dispersed pigments and detergents; active ingredient in Euxyl K 400 and Tektamer 38.
