Abstract

A pre-vapor formulation that may be included in an e-vaping device (60) may include a solvent and a solution compound. The solvent may include one or more of propylene glycol and glycerin. The solution compound may include one of a saccharide compound, a salt compound, and a polyethylene compound. The concentration of the solution compound may be between about 0.2 percent and about 10 percent.

Description

technical field [0001] Some example embodiments relate to pre-vapor formulations for electronic vapor devices. Background technique [0002] An E-vaping device, also referred to herein as an electronic vaping device (EVD), vaporizes a pre-vapor that can be drawn through one or more outlets of the E-vaping device. thing. An vaping device may typically contain several vaping elements, including a power supply section and a cartridge. The power section may contain a power source such as a battery, and the cartridge may contain a heater and a reservoir capable of holding pre-steam formulation material. The cartridge typically contains a heater in fluid communication with the pre-steam formulation via a dispense interface (eg, a wick), the heater being configured to heat the pre-steam formulation to generate steam. [0003] Pre-steam formulations generally contain materials or combinations of materials that are convertible to steam. For example, pre-steam formulations may com...
