RIVM | Research shows that e-liquids mainly contain sweet aromas and flavors

It is the first time that the chemical taste composition of so many liquids from electronic cigarettes (e-liquids) has been analyzed in Europe. RIVM examined 320 e-liquids. In those 320 e-liquids, 79 different aromas and flavors were examined. Vanillin was present in 42 percent of the liquids studied. Substances with a fruity taste also scored highly. The e-liquids studied contain an average of 6 different flavors.

The researchers divided all e-liquids into taste categories, such as dessert, fruit or tobacco, based on their taste label. The research shows that e-liquids with similar taste categories also have a similar composition of aromas and flavors. For example, they found a comparable flavor composition for fresh-sweet, warm-sweet, fresh-cooling, and non-sweet e-liquids flavors.
