Introduction
E-liquid is a term describing liquid either prefilled in vaping products, or available in other forms so that
consumers can fill the reservoirs or soak the wicking material of vaping products. E-liquids may or may
not contain nicotine or nicotine salts. In either case, they generally contain glycerol and/or propylene
glycol together with additional flavouring components. E-liquids are intended to be aerosolised for
inhalation by the user.
This document establishes the general principles and requirements related to ingredients used in e-
liquids and e-liquid components to ensure an appropriate level of consumer safety.
The content is applicable to producers and distributors in Europe and forms a guide for regulators,
enforcement authorities and commercial operators in the area. It is also applicable to consultancies,
laboratories and testing houses engaged in, or planning to be engaged in, the safety evaluation of e-liquids
and e-liquid components.
Not all elements of these recommendations will apply to every type of product, but the definitions may
be used to identify recommendations for specific products within the product sector.
This document can provide state of the art guidance on ensuring the consumer safety of e-liquid
ingredients. Note that as a matter of course, in cases where national regulations currently exist, said
regulations take precedence over this document.
