Perfumes are a combination of various ingredients, including alcohol, oils, water, and fragrance chemicals. The presence of alcohol and other flammable ingredients in perfumes makes them susceptible to combustion. Perfumes can catch fire and explode when exposed to heat or an open flame, which can result in serious accidents and injuries. While the risk of explosion is relatively low under typical conditions, it is crucial to handle and store perfumes safely, keeping them away from sources of ignition and exercising caution when using them near heat or flames.

| Exposure to extreme heat | Can cause the air trapped inside the bottle to expand and rupture the container |
| Exposure to sunlight | Can damage the perfume, causing it to smell like alcohol or vinegar |
| Exposure to humidity | Can negatively react with the perfume's chemical composition |
| Exposure to oxygen | Can cause the scent to evaporate |
| Shaking of the bottle | Can speed up the oxidation process and damage the perfume |
| Glass bottle of lower quality | More prone to rupture |
| Plastic containers | Can melt and allow gas to escape, creating a fire hazard |
| Exposure to flame or spark | Can ignite the flammable liquids in perfume |
| Exposure to ethanol | Can cause the perfume to catch fire and explode |

What You'll Learn
Flammable ingredients
Perfumes are flammable liquids. The ethanol-water solvent used in most perfumes is a great diffuser but is also highly flammable. The base of a perfume is usually alcohol or water, with ethyl alcohol being the most common ingredient because it evaporates quickly on the skin. Other bases include coumarin, benzyl benzoate, phthalates, and even beeswax. According to sciencing.com, “a perfume consists of 78 to 95 percent ethyl alcohol”, which has a flashpoint of 55 degrees Fahrenheit, meaning it will definitely burn.
Aerosol-based perfumes can easily ignite if near a flame. Perfumes do not spontaneously combust – even in hot cars – unless kept next to a flame. However, extreme heat and changes in air pressure can cause the air trapped inside the perfume bottle to expand and rupture the container, usually made of glass. This is a rare occurrence and the quality of the bottle plays a key role in the process. Plastic containers usually melt and allow the gas to escape, creating a fire hazard.
Perfumes should be stored at a consistent temperature (12°C to 22°C) in a dark and dry closet. Sunlight, UV rays, humidity, and constant movement can negatively affect the chemical composition of perfumes, reducing their lifespan and quality.
There have been reports of perfume bottles exploding and causing injuries. In one instance, a father and his son received burns on their faces and abdomens when a perfume bottle caught fire and exploded as the son played with a cigarette lighter. In another incident, a similar situation occurred when a child tried to recreate a YouTube video on how to use a lighter with perfume to create a flash of fire.

Heat exposure
The ideal storage temperature for perfume is between 12°C and 22°C in a dark, dry place. Sunlight, UV rays, and humidity can damage the chemical composition of perfumes, reducing their lifespan and quality. Long-term exposure to heat and sunlight can cause perfumes to smell more like alcohol or vinegar, become discoloured, and appear oily or cloudy. Heat can also cause the ethanol in perfumes to evaporate, changing the composition and potentially impacting the fragrance.
Additionally, it is important to avoid exposing perfume to extreme temperature changes. For example, if a bottle of perfume is stored in a cold place and then quickly moved to a hot environment, the rapid expansion of air inside the bottle could cause it to explode. This is similar to what happens when a cold bottle is handled by warm hands, which can cause the glass to shatter.
While heat exposure can affect the quality and safety of perfumes, it is important to note that perfumes do not spontaneously catch fire, even in hot environments. An ignition source, such as a flame or spark, is required for an explosion to occur. However, once ignited, perfumes can easily catch fire and pose a safety risk.
To minimize the risk of heat exposure, it is recommended to store perfumes in a cool, dry place, away from direct sunlight and heat sources. This will help maintain the integrity of the perfume and prevent potential safety hazards.

Sparks or open flames
There have been several reported incidents of serious injuries caused by perfume explosions. In one case, a father and his young son sustained burns to their faces and abdomens when the father attempted to open a bottle of perfume while his son was playing with a lighter. The lighter ignited the perfume, causing a fire and subsequent explosion. In another incident, a similar scenario played out after a child watched a YouTube video demonstrating how to create a flash of fire using perfume and a lighter.
Additionally, it is important to note that extreme heat can cause the air trapped inside a perfume bottle to expand and rupture the container, particularly if the bottle is made of lower-quality glass. While this may not result in an explosion, it can create a dangerous situation if the perfume comes into contact with an ignition source.
To minimize the risk of sparks or open flames igniting perfume, it is crucial to store perfume at a consistent temperature, ideally between 12°C and 22°C, in a dark, dry, and well-ventilated location. Avoiding exposure to direct sunlight, UV rays, and extreme temperatures is essential to prevent the perfume from deteriorating and increasing the risk of flammability.
Furthermore, when handling perfume, especially during application, it is important to avoid any potential ignition sources, such as lit cigarettes, matches, or lighters. By taking these precautions, the risk of sparks or open flames causing a dangerous explosion or fire involving perfume can be significantly reduced.

Glass bottles
To prevent explosions, perfume bottles should be stored in a cool, dark place, away from heat sources. Suitable storage locations include closet shelves or drawers in temperature-stable rooms. Windowsills, bathrooms, and areas near radiators should be avoided.
Small scratches on glass bottles can also contribute to explosions by creating weak points in the glass that can fracture and shatter under pressure.
Even without temperature changes or external pressure, glass bottles can occasionally explode due to internal forces. When glass cools, some areas may shrink more than others, causing pent-up tension within the material. This tension can sometimes be released suddenly and spontaneously, causing the glass to explode.

Safe storage and handling
To prevent explosions, it is important to always store and handle perfumes safely. Here are some detailed instructions for safe storage and handling:
Firstly, always store perfume in a cool, dry place, away from direct sunlight. The ideal storage temperature for perfume is between 12°C and 22°C. Extreme heat can cause the air trapped inside the perfume bottle to expand and rupture the container, especially if the bottle is made of low-quality glass. Additionally, sunlight and humidity can react negatively with the chemical composition of perfumes, accelerating their breakdown and reducing their lifespan and quality. Therefore, it is best to keep perfumes in a dark and dry closet or cabinet.
Secondly, avoid exposing perfume bottles to sudden temperature changes or flames. While perfumes themselves do not spontaneously catch fire, they are flammable liquids, especially due to the ethanol-water solvent commonly used in them. Extreme heat can cause the ethanol-water mixture to act as an accelerant, igniting and causing an explosion if exposed to an open flame or spark. Always handle perfume bottles with care and avoid grabbing them too tightly, as cold hands on a hot bottle can cause the glass to shatter.
Thirdly, never leave perfume bottles in a car. The interior of a car can get extremely hot, especially in direct sunlight, and the constant movement and shaking of the vehicle can speed up the oxidation process, damaging the perfume and increasing the risk of explosion. If you must leave perfume in a car for a short period, place it inside a dark glovebox, away from direct sunlight, and ensure it is sealed tightly to prevent leakage.
Finally, always treat perfumes as potentially flammable and handle them with caution. Do not spray perfume near open flames or sparks, including lit candles, stovetops, or recently extinguished matches or lighters. Keep perfumes away from children and educate them about the safe handling of perfumes to prevent accidental fires or explosions.
By following these guidelines, you can safely store and handle perfumes while minimizing the risk of explosions or other accidents.
