Is Lysol Aerosol Flammable?

In this article, we will answer the following question: “Is Lysol Aerosol Flammable?”. We will also show important product characteristics and other risks involved in using the product.

Is Lysol Aerosol Flammable?

Yes, Lysol aerosol is flammable, and there’s a big risk of explosions as well. The product contains flammable gas under pressure which may explode if heated or sprayed over an ignition source. 

What is Lysol aerosol?

Lysol Aerosol is a disinfectant for commercial and professional use.

Lysol® is a brand that’s been active for more than a century. 

It’s focused on developing cleaning products such as disinfectant wipes and sprays, bathroom cleaners, multi-purpose cleaners, laundry sanitizers, and Lysol smart kits.

Currently, there are four major Lysol disinfectant aerosol labels in the market, they have various fragrances. They are:

  • Lysol® Disinfectant Spray;
  • Lysol® Pet Solutions Odor Eliminator;
  • Lysol® Disinfectant Spray – Neutra Air 2 in 1;
  • Lysol® Disinfectant Spray to Go.

Some labels and fragrances may not be available in your country.

What is it good for?

Lysol aerosols are intended for cleaning porous and non-porous surfaces. It can sanitize and disinfect by killing germs 

It’s intended to be used on pre-cleaned surfaces. The disinfectant may not be able to reach inner layers of filth if there’s a thick layer of dirt. The same thing happens for any disinfectant.


Germs are microscopic beings that can be detrimental to human life. They can cause direct harm to humans, pets, and other forms of life, but also indirect problems like the formation of mold on surfaces.

Some germs can give us infectious diseases. We can then pass the illness along to other people or even pets. Some microbes can also “rest” on surfaces, waiting for the next human to get in contact with them.

This is why disinfection is important. It can prevent diseases from spreading.

There are many types of microbes. Bacteria, Viruses, Fungi, and Protozoa are the most common, but also exist microscopic animals and plants.

Germs can be found almost anywhere on our planet. We can’t really prevent a microbe from existing in a certain place, we can only avoid it from settling in our living spaces.

Every breath you take, drink you have, the food you eat, and things you touch are full of microbes. Most of them are just living their life unaware of our existence and can’t cause us harm, but many are hazardous and require disinfection.

Luckily our immune system can actively and constantly fight microscopic menaces, but it can’t do everything alone. Hygiene is essential so we can live healthier lives.

How to use it?

According to the fabricant, all surfaces must be pre-cleaned before applying the product. 

To sanitization take place, the spray must be applied from 3 to 4 seconds, at a distance between 15 and 20cm (6 to 8 inches), and cover the surfaces in a mist.

If you plan only on sanitizing, surfaces must remain wet for at least 10 seconds and then allow them to dry naturally in the air. 

Although, if you wish to disinfect something, the surface should remain wet for at least 3 minutes, and then allow it to dry the same way.

To control and prevent mold and mildew, disinfection is required by the fabricant, so 3 minutes of action are required.

If the product you’re using is a deodorizer, it doesn’t require such a long applying time to deodorize. But if you wish to disinfect using such a product, the same 3 minutes of action are required.

The 2 on 1 disinfectant aerosol is the only label that requires more time for disinfection to happen, 5 minutes.

Aerosol Chemistry

Commercially, aerosols are under pressure gasses or liquids that can be expelled outside a can, being carried by a propellant.

Solvents and propellants have the function of regulating the consistency of the active ingredient in the aerosol (in this case, ethanol).

Since the chemical properties of the active ingredient, the propellants, and the solvents are similar, they can present some level of interaction with each other. 

This interaction promulgates that the mist that comes out of the can is optimized for the best disinfectant action possible. It can drag the active solvent efficiently into the surface that will be cleaned.

Unfortunately, the best and most common solvents are all flammable, so almost all aerosols present a high level of flammability.

Lysol aerosol flammability

According to the safety data sheet available by the company, all Lysol Aerosol disinfectant sprays are flammable.

This is because they are all ethanol-based. There are also other flammable constituents in these aerosols,  but ethanol is the one in greater amounts. 

If the aerosol contains a flammable compound, the whole product is flammable. A list of flammable substances commonly found on disinfectant aerosols can be found below.

  • Ethanol
  • Butyl alcohol
  • butane
  • propane
  • hexenol

Nearly any chemical substance that ends with “ol”, “ane”or “one” can present at least some level of flammability.

It is true that the solvents and propellants in Lysol aerosols are very flammable, but only while they are inside the can and a few moments after the spray is used.

The compounds that come out of the flask are all highly volatile, which means that they are lighter than the air and can escape easily. 

Once the product is applied, alcohol and other active ingredients (depending on the label) will remain on the surface for some time, while the other gasses will quickly dissipate across the room.

After a while, the active ingredients themselves will also dissipate, and the risk of flammability will eventually cease.

Scattered volatile compounds are not flammable unless there was already a big fire happening close by, in the same room.

As long as the instructions on the label are followed, there’s no reason to fear using aerosol disinfectants.


There are many types of Lysol Aerosols, but they all are very flammable. The manufacturer provided all the safety data required in this article. As long as the instructions in the label are followed, the risk of toxicity and flammability are minimal.

Frequently Asked Questions (FAQS): Is Lysol Aerosol Flammable?

Is Lysol Spray Hazardous?

Lysol aerosol can be hazardous if inhaled or ingested. First Aid measures should be applied if needed. More information can be found here.

Can I fly with Lysol spray?

It depends on your country’s laws but, overall, you can’t bring pressurized items to a plane in your luggage unless it is specifically allowed to, like certain forms of medicine and personal use goods.

What are the most contaminated items at home?

Toothbrush, kitchen sponge, a cutting board, the kitchen sink, light switches, bed sheets, towels, kitchen sink, handles and the whole bathroom are normally easier contaminated. 

What are the germiest places in school?

Anything that’s handled a lot. Examples: the restroom door, door handles, cafeteria trays and utensils, desks, classroom supplies, and drinking fountains.
