Detection of acrolein, formaldehyde and acetaldehyde in an e-liquid

An aldehyde is a volatile organic compound (VOC). They are used in many industries such as agriculture, textiles or chemicals, etc. They are also the degradation products obtained when chemical substances are heated.

Which aldehydes are potentially present in e-liquids and their emissions?

Among the large aldehyde family, only analysis of formaldehyde, acetaldehyde and acrolein is recommended by the standard AFNOR XP D90-300 (Part 2: standard on e-liquids & Part 3: standard on emissions). This French standard with voluntary application for e-liquid manufacturers fixes the maximum concentrations for these 3 molecules in products.


This is a compound produced naturally by plants, fruits and flowers. It comes from the degradation of aromatic molecules, plentiful in e-liquids.


This is used in many industrial sectors as preservative, disinfectant, or corrosion inhibitor. It comes from the degradation of propylene glycol (PG).


This is a compound that comes from the degradation of vegetable glycerine (VG).

These 3 aldehydes can be present in e-liquid as residual compounds of the raw materials used. They are potentially present in the aerosol. Indeed, the heating phenomenon linked to using an electronic cigarette favours the formation of these compounds.

Why look for the presence of acrolein, formaldehyde and acetaldehyde in e-liquids and their emissions?

The 3 aldehydes studied in this service are considered as dangerous because they can present a toxic risk in inhalation. They cause a restriction of the respiratory routes and are considered as carcinogens. The national institute for research and safety for preventing work accidents and occupational diseases (INRS) fixed the threshold values of inhalation for these molecules.

To ensure the safety of consumers, the ingésciences laboratory checks the levels of these 3 aldehydes and their emissions for e-liquid manufacturers.

Their contents in e-liquids and their emissions are measured by ingésciences using an UHPLC-UV-MS.
