Does e-cigarettes contain formaldehyde? What harm does e-cigarette formaldehyde have to human body?


Now that the e-cigarette market is getting hotter and hotter, more vapers switch to use e-cigarettes instead of traditional cigarette products because they want to use e-cigarettes to quit smoking, but e-cigarettes can cause harm to our bodies. E-cigarettes produce formaldehyde gas when they are burned, so how harmful is the formaldehyde of e-cigarettes to the human body? Let’s take a look!

The e-cigarettes hyped by many news media contain formaldehyde. Is this alarmist or is it true?

Based on the public’s incomplete understanding of formaldehyde and e-cigarettes, this statement has caused a large number of e-cigarette consumers to fear.

Don’t panic, formaldehyde is a word that everyone hears often. It is often mentioned after the renovation of new houses. It is used to produce building materials (including pressed wood products) and many household products, and even part of the manufacturing process of anti-wrinkle cloth; Formaldehyde can also come from a variety of chemical and light industrial products such as cosmetics, detergents, pesticides, disinfectants, preservatives, printing inks, paper, and textile fibers.

Correspondingly, the main hazard of formaldehyde is the irritation to the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. When the concentration of formaldehyde reaches 0.06-0.07mg/cubic meter per cubic meter of air, children will have mild asthma.

When the formaldehyde in the indoor air reaches 0.1mg/m3, there will be peculiar smell and discomfort; when the formaldehyde reaches 0.5mg/m3, it can irritate the eyes and cause tearing; when the formaldehyde reaches 0.6mg/m3, it can cause throat discomfort or pain . At higher concentrations, it can cause nausea and vomiting, coughing, chest tightness, wheezing and even pulmonary edema; when formaldehyde reaches 30mg/m3, it will immediately cause death.

After learning about formaldehyde, let’s see if there is really formaldehyde in electronic cigarettes? Is formaldehyde serious as stated on the Internet?

In electronic cigarettes, the main components that produce formaldehyde: propylene glycol and glycerin.

The principle is: 8 kinds of volatile carbonyl compounds generated by the cracking of propylene glycol and glycerol; at high temperatures, these two substances will have a cracking reaction and start to produce formaldehyde. The formaldehyde will be completely released when the temperature reaches above 400°.

However, most of the pod kits that are popular on the market now have the atomization temperature controlled below 300° (it is impossible to exceed 300° under normal operation depending on the cartridge structure and output power.

China’s CB/T 18883-2002 “Indoor Air Quality Standard” stipulates that the hourly limit of formaldehyde in the indoor air of Class II civil construction projects is 0.10mg/m3, and the limit of formaldehyde per hour in the indoor air of Class I civil construction projects is 0.08mg/cubic meter. One type of civil construction project includes residential buildings, hospitals, school classrooms, elderly buildings, and kindergartens.

This is the experimental basis obtained under unconventional mechanical operations, but in actual operation, it can be understood that one person needs to consume continuously within an hour and vape 10-15ml of e-liquid.

E-cigarettes contain formaldehyde, but within the safety range of the national standard, where does the online formaldehyde exceed the standard?

The British Medical Journal “NEJM” survey report concluded: “When vapers use high-voltage and high-power electronic cigarettes under extreme conditions, they can indeed produce a certain level of aldehydes. This situation is caused by unconventional operations. Above 400°, excessive formaldehyde will occur in the case of dry burning.

In reality, the voltage and power of e-cigarette are rarely raised to the levels mentioned in the research, because the smell of this kind of smoke is unpleasant, and it is difficult for users to inhale such vapor.

The formaldehyde present in cigarettes far exceeds the CB/T 18883-2002 “Indoor Air Quality Standard”, the limit of formaldehyde per hour in indoor air is 0.10mg/m3. This is the accepted data.

The final conclusion: users who use e-cigarette reasonably under normal conditions will not reach the dangerous level of formaldehyde. Even if they use high-power e-cigarettes, the formaldehyde emission is much lower than that of cigarettes.
