e-liquids
With consumer safety and satisfaction at the forefront of everything we do, product stewardship is paramount at BAT. Our multidisciplinary teams of scientists ensure our products meet the highest quality and safety standards, whether that’s the battery, device materials or e-liquid ingredients.
 
What’s in e-liquids?

Our e-liquids have been custom made to our devices to ensure optimum performance and flavour. They are mostly made from five ingredients: vegetable glycerine (VG), propylene glycol (PG), flavourings, nicotine and water.

Only flavourings and ingredients of food-grade quality are considered for use; we also prohibit the use of any additives or materials that are classified as carcinogenic, causing genetic mutations or reproductive toxicity, or lead to respiratory allergy if inhaled.

Evolving regulation

Regulation of vapour products is still developing and can vary according to jurisdiction. More comprehensive, evidence-based oversight of this rapidly evolving sector is needed. BAT’s scientists are generating good quality science to inform and enrich the dialogue.

Nicotine salts in e-liquids

Nicotine salts occur naturally in tobacco when nicotine reacts with tobacco acids. Consequently, the burning of tobacco and the aerosolisation of nicotine salts is part of the cigarette smoking experience.

In an effort to make vaping more acceptable to cigarette smokers, our scientists are constantly experimenting to try to replicate the smoking experience, but without the high levels of toxicants created by combustion. Our application of nicotine salts in Vuse vPro liquids and our continued research into optimisation of those formulations is part of a continued R&D effort to make vaping more acceptable to smokers1.

Flavour technologies

Flavour is a key driver of vapour product satisfaction for both existing vapers and smokers entering the category. To deliver the most authentic tobacco experience possible we have pioneered the use of biomimetic technology in our e-liquids, analysing the volatile components associated with the aroma of cured leaf and synthetically copying that flavour into an e-liquid. More recently we have expanded the use of this technique into replicating the aroma profiles of naturally sourced mints with the aim of offering our consumers an unrivalled portfolio of authentic, differentiated mint flavours.
