What Happens to the Wax Molecules During Burning

When a candle burns, the wax molecules undergo several chemical changes as they transform from a solid to a gas. Understanding these changes can provide valuable insights into the chemistry of candle burning. Here’s a closer look at what happens to the wax molecules during the process:

  • Melting: The heat from the flame causes the solid wax to melt and form a pool of liquid wax around the wick.
  • Vaporization: As the liquid wax near the wick heats up, it vaporizes and turns into a gaseous state. This gaseous wax then reacts with oxygen in the air.

During this transformation, several new substances are created as a result of the chemical reactions taking place. These include carbon dioxide, water vapor, and potentially soot and other particulate matter. Additionally, depending on whether scented oils or additives are present in the wax, specific fragrances or chemicals may also be released into the air.

As such, understanding what new substances are made when making a candle burn is essential for assessing both the environmental impact of candle burning and its potential health effects. It also sheds light on how different types of candles or additives can influence air quality and indoor environments.

The Emission of Carbon Dioxide and Water Vapor

During the process of burning a candle, several chemical reactions take place that result in the production of new substances. One of the main products of candle burning is the emission of carbon dioxide and water vapor. When a candle burns, the heat from the flame vaporizes the candle wax, breaking down its molecular structure and releasing carbon dioxide and water vapor into the air.

The chemical reaction that occurs during candle burning can be described by the formula CxHy + (x+y/4)O2 – > xCO2 + (y/2)H2O, where CxHy represents the hydrocarbons found in the wax. This equation illustrates how the combustion of hydrocarbons in the presence of oxygen leads to the formation of carbon dioxide (CO2) and water vapor (H2O). These gases are released into the surrounding environment as byproducts of candle burning.

It is important to note that while carbon dioxide and water vapor are natural byproducts of combustion, excessive exposure to these gases can have environmental implications. In poorly ventilated areas, prolonged exposure to high levels of carbon dioxide can lead to health concerns.

Additionally, when candles are burned in enclosed spaces without proper ventilation, they can contribute to an increase in indoor humidity levels due to the release of water vapor. Understanding these chemical processes sheds light on how candle burning can impact both indoor air quality and overall environmental conditions.

Soot and Particulate Matter

When a candle burns, it undergoes a chemical reaction that results in the formation of several new substances. One of these by-products is soot, which is comprised of tiny carbon particles that are emitted into the air during the combustion process. The release of soot and other particulate matter can have negative effects on both indoor air quality and human health.

Composition of Soot



Soot is formed when the carbon-containing compounds in the candle’s wax do not fully combust, leading to the creation of small, solid particles. These particles can vary in size and composition depending on the type of wax used in the candle, as well as any additives or fragrances present. In addition to carbon, soot may also contain trace amounts of other elements such as sulfur and nitrogen, which contribute to its potential harmful effects.

Health Concerns

The release of soot and particulate matter during candle burning can pose health risks, especially for individuals with respiratory conditions such as asthma or allergies. Inhaling these tiny particles can irritate the lungs and airways, leading to symptoms such as coughing, wheezing, and shortness of breath. Long-term exposure to airborne pollutants like soot has also been linked to more serious health issues such as cardiovascular disease and lung cancer.

Preventing Soot Formation

To minimize the amount of soot produced during candle burning, consider using candles made from cleaner-burning waxes such as soy or beeswax. Trimming the wick to a proper length before lighting the candle can also help promote more complete combustion of wax molecules and reduce sooting. Additionally, ensuring proper ventilation in the area where candles are being used can help disperse airborne particles and improve indoor air quality.

The Release of Fragrance and Scented Oils

When a candle burns, it not only produces heat and light, but it also releases fragrance and scented oils into the air. This process adds an extra dimension to the experience of burning candles, as it enhances the atmosphere and can create a pleasant aroma in a room. The release of fragrance and scented oils is an important aspect of candle burning that many people enjoy.

How Fragrance Is Released

The release of fragrance from a burning candle occurs when the heat from the flame vaporizes the scented oils within the wax. These vapors are then dispersed into the air, allowing the aroma to spread throughout the surrounding space. The intensity of the fragrance released can be impacted by factors such as the type and amount of scented oils used, as well as the size and composition of the wax.

The Chemical Changes

During this process, new substances are created through chemical reactions between the heat, wax molecules, and scented oils. The specific compounds produced will depend on the ingredients used in making the candle.

Generally speaking, when a candle burns, it undergoes combustion which transforms its components (wax and additives) into carbon dioxide, water vapor, soot particles, and other byproducts. Furthermore, fragrances that are formulated using essential oils or synthetic compounds will produce their own unique set of chemical changes when heated during burning.
