These emissions can have implications for indoor air quality and human health making it important to choose candles made from waxes with less harmful emissions.
The Process of Combustion and Candle Burning
When a candle burns, it goes through the process of combustion, which involves the chemical reaction between the wax and the oxygen in the air. This process is what produces the heat and light that we associate with burning candles. Understanding the chemistry of combustion can help us understand what new substances are formed during candle burning.
During the combustion of a candle, various substances are produced as a result of the chemical reactions taking place. Some of these substances include:
- Carbon dioxide (CO2): When the carbon atoms in the wax combine with oxygen during combustion, they form carbon dioxide. This is a colorless and odorless gas that is released into the air during candle burning.
- Water vapor (H2O): The hydrogen atoms in the wax combine with oxygen to form water vapor. This is why you may notice condensation on nearby surfaces when burning a candle.
- Soot: Incomplete combustion can result in the formation of soot, which consists of tiny particles of carbon. These particles can be released into the air and contribute to indoor air pollution.
It’s important to note that the composition and emission of these substances can vary depending on factors such as the type of wax used, additives in the candle, and how well-ventilated the space is where the candle is burned. Therefore, proper ventilation and safety considerations should always be taken into account when burning candles indoors.
Emission of Gases and Particles During Candle Burning
When a candle burns, it emits a variety of gases and particles into the air. Understanding the emission of these substances is important for both indoor air quality and general safety considerations when burning candles at home. The following are some of the new substances that are made when making a candle burn:
– **Carbon Dioxide:** When a candle burns, one of the primary substances produced is carbon dioxide (CO2). This occurs as a result of the combustion process where the carbon in the wax combines with oxygen from the air.
– **Water Vapor:** Another byproduct of candle burning is water vapor (H2O). As the hydrocarbons in the wax molecules are oxidized during combustion, they also produce water vapor as part of the chemical reaction.
– **Soot and Other Particulate Matter:** In addition to gases, candles also emit soot and other particulate matter into the air as they burn. This can include tiny carbon-based particles that are visible as smoke or invisible particles that contribute to air pollution.
It’s important to note that while these substances are produced during candle burning, their impact on indoor air quality can vary depending on factors such as ventilation, candle composition, and burning conditions.

The Formation of Carbon Dioxide and Water Vapor
When a candle burns, it undergoes the process of combustion, which involves the chemical reaction between the wax and oxygen in the air. This process results in the formation of carbon dioxide and water vapor as byproducts. The chemical composition of candle wax, typically made from hydrocarbons such as paraffin or soy wax, plays a crucial role in this reaction.
As the flame of the candle heats up the surrounding wax, it melts and eventually vaporizes into a gas phase. Once in the gaseous state, these hydrocarbon molecules react with oxygen molecules in the air to produce carbon dioxide (CO2) and water vapor (H2O). This is a fundamental aspect of candle burning and contributes to its characteristic glow and warmth.
The emission of carbon dioxide and water vapor during candle burning is not harmful to human health when candles are used in well-ventilated areas. However, in enclosed spaces with poor ventilation, these byproducts can contribute to an increase in indoor carbon dioxide levels and humidity. It’s important for individuals to consider these factors when using candles indoors for extended periods of time.
The Release of Soot and Other Particulate Matter
When a candle burns, it undergoes a process called combustion, which involves the chemical reaction between the wax and oxygen in the air. As part of this process, soot and other particulate matter are released into the surrounding environment. These particles are small enough to be suspended in the air, and their release can have implications for indoor air quality.
The amount of soot and particulate matter released during candle burning can vary depending on factors such as the type of wax used, the presence of additives or dyes in the candle, and even the design of the wick. For example, candles made from paraffin wax tend to produce more soot compared to those made from soy or beeswax. Additionally, candles with thicker or multiple wicks may produce more soot than those with thinner or single wicks.
Exposure to soot and other particulate matter from candle burning has been associated with potential health effects such as respiratory irritation, aggravation of existing respiratory conditions (e.g. asthma), and in some cases, cardiovascular issues. It is important for individuals who frequently burn candles indoors to be mindful of these potential health implications and take steps to minimize their exposure to indoor air pollutants from candle burning.
