Description

A Chinese-style flue-cured tobacco-flavored e-cigarette liquid that effectively reduces the sweetness and greasy feeling in the mouth

technical field

The invention relates to a Chinese-style flue-cured tobacco-flavored electronic cigarette liquid that can effectively reduce the sweetness and greasy feeling in the mouth, and belongs to the technical field of electronic cigarettes.

Background technique

With the gradual implementation of the "Framework Convention on Tobacco Control", the continuous development of the global tobacco control campaign, and the vigorous promotion of harm reduction and coke reduction by the national bureau, people pay more and more attention to health, making the living environment of cigarettes increasingly severe. In order to meet the needs of different consumers, various imitation cigarette products are emerging, among which e-cigarettes are the most common, and have been widely recognized and developed globally, especially in European and American countries. According to scientific and objective judgments, the progress of electronic cigarette products is also accelerating and promoting the industry's progress in a benign and healthy direction. However, most of the e-cigarette liquids currently on the market have an overly sweet and greasy feeling in the mouth after smoking, which gives people a very uncomfortable feeling, and the tobacco flavor is too weak to satisfy those who are used to smoking Chinese flue-cured tobacco. Domestic consumers of cigarettes have seriously restricted the development of electronic cigarettes.

Dipropylene glycol, also known as dipropylene glycol, is an odorless, colorless, water-soluble and hygroscopic liquid. It is currently mainly used in the fields of flavors, fragrances and cosmetics. There are no reports of its application in e-cigarette liquids.
