These particles can include carbon dioxide, water vapor, and other gases, as well as soot and other particles. However, the question is whether candles also emit carbon monoxide, a highly toxic gas that can cause serious health problems.
The short answer is that candles can emit carbon monoxide, but the amount is usually very small. In fact, in most cases, the levels are not high enough to pose a health risk to humans. However, if you’re concerned about the potential dangers of carbon monoxide from burning candles, there are some things you can do to minimize the risk. So, let’s take a closer look at what you can do to ensure that you and your loved ones stay safe while enjoying the comfort and ambiance of candlelight.
What is Carbon Monoxide?
Carbon monoxide or CO is a toxic gas that is formed by the incomplete combustion of fuels such as gasoline, oil, wood, and natural gas. It is a colorless, odorless, and tasteless gas that cannot be easily detected by humans. This gas is highly poisonous and can cause serious health problems and even death to individuals exposed to it. Carbon monoxide can be emitted by various sources like cars, generators, stoves, furnaces, and of course, candles.
How are candles made?
Candles have been around for thousands of years and have played a significant role in human history, providing light in times of darkness and adding warmth to our homes. But have you ever wondered how candles are made?
- The first step in making a candle is to choose the wax. There are various types of wax available, including paraffin wax, beeswax, soy wax, and others.
- Once the wax is selected, it is melted in a double boiler. This is a heating system that uses two pots, one on top of the other, to melt the wax slowly and evenly.
- Next, the wick is placed in the center of the candle container. The wick is made of cotton and is coated with wax so that it will burn evenly.
- The melted wax is then poured into the candle container around the wick and left to cool and harden.
- After the wax has hardened, the excess wick is trimmed, and the candle is ready to use.
Do candles emit carbon monoxide?
Carbon monoxide is a colorless, odorless gas that is produced when fuels, such as wood, coal, or gas, are burned. It is a toxic gas that can cause serious health problems, including headaches, dizziness, nausea, and even death.
So, do candles emit carbon monoxide?
While burning candles can release some carbon monoxide, the amount is minimal and not dangerous in a well-ventilated area. In fact, the amount of carbon monoxide released by burning candles is significantly lower than the amount released by burning other fuels, such as coal or wood.
However, burning candles in an enclosed space, such as a small room with poor ventilation, can increase the concentration of carbon monoxide to harmful levels. That’s why it’s essential to make sure your home is well-ventilated, especially if you burn candles regularly.
| Fuel | Carbon Monoxide Emission (grams per hour) |
|---|---|
| Paraffin Wax Candle | 0.009 |
| Beeswax Candle | 0.0005 |
| Coal | 150 |
| Wood | 30 |
As you can see from the table above, burning candles produces very little carbon monoxide compared to other fuels. So, if you enjoy burning candles in your home, you can do so safely as long as you make sure your home is well-ventilated.
What chemicals are used in candle production?
Candle production involves the use of various chemicals, some of which may be harmful to human health and the environment. Below are the chemicals commonly used in candle manufacturing:
- Wax: The most common types of wax used in candle production are paraffin, beeswax, soy wax, and palm wax. Paraffin is a petroleum-based wax that is known to emit harmful chemicals when burned, such as toluene and benzene.

What is the composition of candle wax?
Candle wax is traditionally made from animal fats or oils, such as beeswax or tallow, but in modern times, synthetic wax made from petroleum, called paraffin wax, has become the most commonly used material in candle making. Paraffin wax is made from refined petroleum and contains hydrocarbons, which are molecules made up of hydrogen and carbon. The length and shape of these molecules can affect the properties of the wax, such as its melting point, hardness, and flammability.
Properties of candle wax
- Candle wax must be able to hold a wick upright and straight while burning.
- It should have a low melting point so that the wax melts around the wick and evaporates into the air to create a flame.
- It should be combustible and have a high energy density to provide a bright and long-lasting flame.
Does burning candles emit carbon monoxide?
Candles do not emit significant levels of carbon monoxide when burned in a well-ventilated area. Carbon monoxide is a colorless, odorless gas that is produced in high levels when fossil fuels, such as coal and gasoline, are burned in enclosed spaces without proper ventilation. When burning candles, the main byproducts are water vapor and carbon dioxide, which are commonly found in the air we breathe. However, burning large quantities of candles in a small, poorly ventilated room can lead to a buildup of carbon dioxide and other pollutants in the air, which can cause headaches and other health problems.
Types of candle waxes and their properties
Different types of wax can be used to make candles, each with its own unique properties. Here is a summary of some of the most commonly used waxes and their characteristics:
| Wax Type | Characteristics |
|---|---|
| Paraffin Wax | Most commonly used wax. Inexpensive and widely available. Burns longer and brighter than other waxes. Can be blended with other waxes to improve its properties. |
| Beeswax | Natural wax made from honeybees. Has a sweet smell and burns slowly and cleanly. More expensive than other waxes and requires a thicker wick. |
| Soy Wax | Made from soybean oil. Burns cleanly and slowly. Renewable and biodegradable. Often blended with other waxes to improve its properties. |
| Palm Wax | Made from palm oil. Burns brighter than other natural waxes. Renewable and biodegradable. |
It is important to note that different waxes require different types of wicks to burn properly and safely. A wick that is too small or too large for the wax can cause the candle to burn improperly, produce excessive smoke or soot, or become a fire hazard.
How do candles produce light?
Candles produce light through a chemical reaction called combustion. Combustion is a process that occurs when a fuel combines with oxygen to produce heat, light, and byproducts such as carbon dioxide and water vapor. In the case of candles, the fuel is the wax that surrounds the wick.
- When you light a candle, the heat of the flame melts the wax near the wick.
- The liquid wax is drawn up the wick by capillary action, which occurs when liquids flow through narrow spaces without the help of external forces, like gravity.
- As the liquid wax reaches the top of the wick, it is vaporized by the heat of the flame, producing a mixture of hot gases and vaporized wax molecules.
The mixture of hot gases and vaporized wax molecules produces the light that we see from a burning candle. The color of the light depends on the temperature of the flame. A cool flame tends to produce more yellow or orange light, while a hot flame produces more blue or white light.
It’s worth noting that candles also produce carbon dioxide (CO2) and water vapor (H2O) as byproducts of combustion. However, candles generally do not emit significant levels of carbon monoxide (CO), which is a toxic and potentially deadly gas.
Wrap up
Candles produce light through the process of combustion, which involves the melting and vaporization of wax near the wick. The resulting mixture of hot gases and vaporized wax molecules produces the light that we see from a burning candle. While candles do produce carbon dioxide and water vapor as byproducts of combustion, they generally do not emit significant levels of carbon monoxide.
How do candles emit fragrance?
When we light a candle, the heat from the flame melts the wax near the wick, and the liquid wax is drawn up the wick by capillary action. As the melted wax is drawn up the wick, it vaporizes and the heat from the flame causes the vapor to combust, producing the light of the flame. The combustion of the vaporized wax releases energy in the form of heat and light. It also produces water vapor, carbon dioxide, and other combustion by-products, including fragrance molecules.
- As the candle wax burns, the fragrance molecules evaporate and are released into the air.
- The amount of fragrance emitted by a candle depends on the type and amount of fragrance oil added to the wax.
- Some candles use natural fragrances derived from essential oils, while others use synthetic fragrances.
The fragrance molecules emitted by a candle are very small, and they can travel far and wide on air currents. The scent of a candle can fill a room, or even an entire house, depending on the size of the candle and the strength of the fragrance.
If you’re concerned about the impact of candles on indoor air quality, it’s worth noting that while they don’t emit carbon monoxide, they can release other pollutants, such as volatile organic compounds (VOCs) and soot. Some candles are made with natural ingredients that produce less soot and fewer VOCs than others.
| Candle Wax Type | Pros | Cons |
|---|---|---|
| Beeswax | Produces little soot, natural fragrance, long burn time | Expensive, limited variety of scents |
| Soy Wax | Natural and renewable, clean burning, good scent throw | Less durable, may require a larger wick for proper burning |
| Paraffin Wax | Least expensive, wide variety of scents | Produces more soot and VOCs than other wax types |
By understanding how candles emit fragrance and the types of wax used in candle production, you can make informed choices about the candles you burn in your home and their impact on indoor air quality.
What are the health effects of carbon monoxide exposure?
Carbon monoxide (CO) is a colorless, odorless gas that is formed when certain fuels are burned. Exposure to high levels of CO can be extremely dangerous and even deadly. According to the Centers for Disease Control and Prevention (CDC), on average, more than 400 Americans die every year from unintentional CO poisoning, and an additional 20,000 visit emergency rooms due to exposure.
CO poisoning can occur in both acute and low-level exposures. Acute exposure occurs when a person is exposed to high levels of CO, such as in a house fire or from using a gas-powered generator in an enclosed space. Low-level exposure occurs over a period of time and can be just as dangerous.
- Acute exposure symptoms:
- Headache
- Dizziness
- Nausea or vomiting
- Shortness of breath
- Confusion or loss of consciousness
- Death (in severe cases)
- Low-level exposure symptoms:
- Mild headache
- Fatigue
- Shortness of breath
- Mild nausea or vomiting
- Dizziness
The symptoms of CO poisoning can mimic those of other illnesses, so it is important to seek medical attention if you suspect CO exposure. Long-term exposure to low levels of CO can also have serious health effects, including:
- Permanent brain damage
- Memory loss
- Difficulty concentrating
- Depressive symptoms
- Cardiovascular disease
To reduce the risk of CO exposure, it is important to properly maintain fuel-burning appliances and to have working CO detectors in homes and buildings.
| Source | Source Type |
|---|---|
| Centers for Disease Control and Prevention | Government agency |
| Environmental Protection Agency | Government agency |
| World Health Organization | International agency |
It is important to take CO exposure seriously as it can have serious health consequences. Proper prevention measures and early detection can save lives.
How is Carbon Monoxide Measured?
Carbon monoxide (CO) is measured in parts per million (ppm), which is the number of CO molecules per million air molecules. Measuring CO levels is important because even low levels of CO can have adverse health effects, especially for sensitive populations such as children, pregnant women, and the elderly.
- Personal CO monitors: These are wearable devices that can detect and measure CO in the air around you. They are useful for people who work in environments where CO exposure is a risk factor, such as firefighters or construction workers.
- Sampling pumps: These devices use a pump to draw air through a tube into a detector that measures the CO level. They are often used to measure CO levels in confined spaces, such as underground mines or tunnels.
- Area monitors: These are stationary devices that measure CO levels in a specific area over time. They are often used in buildings where there are gas appliances or in parking garages.
CO monitors are calibrated to read ppm levels. The Occupational Safety and Health Administration (OSHA) sets a permissible exposure limit (PEL) for CO of 50 ppm over an eight-hour workday. However, the Environmental Protection Agency (EPA) recommends that people not be exposed to more than 9 ppm of CO over an eight-hour period.
Here is a table that shows the health effects of increasing levels of CO:
| CO Level (ppm) | Symptoms and Health Effects |
|---|---|
| 0-9 ppm | No health effects |
| 10-35 ppm | Headache, nausea, fatigue |
| 36-99 ppm | Headache, nausea, fatigue, dizziness |
| 100-199 ppm | Headache, nausea, fatigue, dizziness, confusion |
| 200-399 ppm | Headache, nausea, fatigue, dizziness, confusion, unconsciousness |
| 400-799 ppm | Headache, nausea, fatigue, dizziness, confusion, unconsciousness, death within 3 hours |
| 800 ppm or higher | Immediate effects: convulsions, respiratory arrest, death within minutes |
It is important to note that even low levels of CO can have long-term health effects, such as damage to the central nervous system and cognitive impairment.
What are the symptoms of carbon monoxide poisoning?
Carbon monoxide poisoning can be a serious and potentially deadly condition. It occurs when carbon monoxide (CO) – a colorless, odorless, tasteless gas that is toxic to humans and animals – is inhaled.
