A solvent for electronic cigarette liquid and an electronic cigarette liquid

Abstract

The present invention provides a solvent for electronic cigarette liquid, comprising triethyl citrate. In the present invention, triethyl citrate alone or in combination with a polyol is used as the solvent for the electronic cigarette liquid. Due to the effect of triethyl citrate, the electronic cigarette liquid which is prepared with the solvent for electronic cigarette liquid provided by the present invention generates relatively greater amount of smoke while being atomized, improves the experience of the smoker, who feels thick and full, neither too dry nor too wet, and has relatively higher comfort level. Furthermore, all the components of the solvent for electronic cigarette liquid provided by the present invention are of food grade, and are harmless to the body of the smoker.
