Summary An unknown migration contaminant was found in a number of mineral water samples contained in beverage carton packages. This compound was isolated by a fully automatic solid phase extraction system and identified by means of GC-MS as 2,4,7,9-tetramethyl-5-decyne-4,7-diol (TMDD) [126-86-3], which is used as a surfactant in water-based printing inks and migrates during the production of the beverage carton material into the inner polyethylene film and subsequently into the product. The determined concentrations of TMDD ranged up to more than 50 μg L−1.
