METHODS AND SYSTEMS FOR IMPROVING THE STABILITY OF PRE-EVAPORATIVE COMPOSITIONS OF E-VAPING DEVICES Russian patent published in 2021 - IPC A24B15/16 A24B15/167 

FIELD: vaping devices.

SUBSTANCE: group of inventions relates to vaping devices and pre-evaporative compositions for electronic vaping devices. The electronic steam generating device contains a cartridge, a heater, and a power supply section. The cartridge includes a tank for placing the pre-evaporative composition in it. The heater is made with the possibility of heating the pre-evaporative composition. The power supply section is connected to the cartridge and is designed to supply power to the evaporator. The composition contains a solvent and a soluble compound. The solvent contains at least one of propylene glycol and glycerol. A soluble compound is at least one of a saccharide compound, a saline solution, and a polyethylene glycol compound.

EFFECT: technical result is a reduction in oxidation and an increase in the stability of the ingredients included in the pre-evaporative composition, an increase in the efficiency of protonation by acids of molecular nicotine in the pre-evaporative composition.
