NineSigma’s client, a leading international tobacco product manufacturer, is currently selling vaping devices that utilize nicotine-containing liquids. Typically, these e-liquids consist out of a mixture of vegetable glycerin (VG), propylene glycol (PG), flavors and nicotine. In combination with various flavors, both solvents contribute for the pleasurable, sensorial experience that e-cig users are expecting when using their vaping device. Additionally, VG and (to a lesser extent) PG are mainly responsible for the well-known, dense vape ‘clouds’ that are being exhaled by e-cig users. However, depending on the environment or location, these dense vapes are not always appreciated.
For this reason, our client is looking for solutions that offer the e-vape user the option to alter the visibility of the exhaled vapes depending on the environment. Since VG and PG are mainly responsible for the visibility, an alternative solvent that doesn’t produce these dense, visible vapes would be an ideal, easy-to-be-implemented solution.
Since the visibility of a smoke is not just dependent on the molecular properties, but also on other parameters such as airflow, density of the vape constituents, particle size distribution and temperature, other solutions that might lead to the elimination of the vape’s visibility are of interest.
The objective of this RFP is to find solutions that allow e-cigarette users to vape without exhaling a visible smoke.
