The use of e-cigarettes is a major issue in public health. At temperature of 300°C, high concentration of glycerol, propylene glycol and flavouring agents render the carrier solvent prone to carbonylation, condensation and dehydration reactions typical of the polyalcohol and sugars fragmentation pools of the Maillard reaction.1 Within this compartmentalized multiphase environment, reactive carbonyl species (RCS) such as aldehydes and ketones are the most potent toxicants in e-cigarette emissions causing cancer, cardiovascular and respiratory diseases.2 Currently, most strategies for reducing e-cig toxicants are based on the design of the product.3 Here we show a new method of trapping RCS in e-cig emissions by adding polyphenols in e-liquid formulations.
