The main components of SONGVAPE e-liquid are nicotine, edible flavorings, vegetable glycerin, and propylene glycol. The independently developed nicotine by SONGVAPE uses a new-generation process, which innovates on the basis of traditional benzoate salts. It retains the fixative effect of traditional benzoate salts while offering a more fragrant and fresh aroma. Apart from nicotine, all other components are common food additives in daily life.
