Candles are typically made of wax, which is non-hazardous and does not require special classification. However, the addition of fragrances, colours, or gels may cause candles to be classified as hazardous materials. The classification of candles as hazardous materials depends on their chemical composition, particularly the concentration of fragrance ingredients. While candles are not inherently dangerous, their flammability poses a risk, and they should be burned in well-ventilated areas to prevent negative reactions in sensitive individuals.
| Characteristics | Values |
|---|---|
| Hazardous Materials | Candles are likely not hazardous materials, but they are considered dangerous goods due to their flammability. |
| Fragrance | Fragrances are considered safe for human use if they meet the specifications set by the IFRA. However, some individuals may have sensitivities to specific fragrances. |
| VOCs | Fragrance ingredients in candles are VOCs (volatile organic compounds). Exposure to VOCs can cause headaches, irritation, nausea, and damage to internal organs. |
| Additives | Candles with additives for fragrance and colour may be hazardous if present in high concentrations and may require warning labels. |
| Sensitisation | If a candle contains more than 0.1% of a sensitizing fragrance ingredient, it should be labelled as such. |
| Allergic Reactions | The EU labelling phrase "EUH208" is used to alert individuals who may be sensitized to specific substances in the candle. |
| Packaging | Packaging for candles must follow the Classification, Labelling, and Packaging (CLP) regulations. Labels must be easily readable and affixed securely to the package. |
| Flammability | Candles are flammable and pose a risk of an open flame, which should be highlighted in pictograms on the labels. |

Candles are not Hazmat if made from wax, but additives may make them hazardous
Candles are not classified as hazardous materials (Hazmat) if they are made from wax. However, it is important to note that the addition of certain fragrances, colours, or gels may cause them to be considered hazardous. The classification of candles as hazardous materials depends on their exact chemical composition. While candles made from wax are generally non-hazardous, it is the additives that can introduce potential risks.
The primary concern with candle additives is their potential to cause sensitisation, which is the development of an allergic reaction to a specific substance. If a candle contains more than 0.1% of a sensitising fragrance ingredient, it is required by law to include a label stating, "Contains [name of fragrance/s]." This warning is crucial for individuals who are sensitive to specific fragrances. Additionally, for highly potent sensitisers, the threshold for labelling may be even lower, at 0.01%.
The presence of volatile organic compounds (VOCs) in candle additives, particularly fragrances, is another factor that can contribute to their hazardous nature. VOCs are compounds composed mainly of carbon, oxygen, and hydrogen, and they can easily evaporate into the air. While not all VOCs are harmful, exposure to certain types or high concentrations of VOCs can have adverse effects. Fragrances in candles can act as sources of VOC emissions, and the greater the concentration of fragrance, the higher the likelihood of triggering health warnings. To ensure the safety of candle fragrances, the formulas are reviewed against the safety standards established by the International Fragrance Association (IFRA).
It is worth noting that the flammability of candles is often cited as a reason for their potential classification as hazardous materials. While candles are inherently flammable, this does not typically result in their classification as Hazmat. However, it is crucial to follow safety precautions when burning candles to prevent accidents or fires.
In summary, candles made from wax alone are not considered Hazmat. However, the addition of fragrances, colours, or gels can introduce potential health and safety risks, leading to their classification as hazardous materials. It is important for consumers to be aware of the ingredients and potential hazards associated with the candles they purchase and to follow proper usage and ventilation guidelines.

Fragrances in candles are VOCs, which can cause irritation and nausea
While candles are not classified as hazardous materials, they may be considered dangerous goods due to their flammability. However, the fragrances in candles are often volatile organic compounds (VOCs) composed of carbon, oxygen, and hydrogen, which evaporate into the air and can be harmful to human health.
VOCs in candles can originate from the wax, fragrance, and wicks, with common VOCs including benzene, toluene, formaldehyde, and acetaldehyde. These compounds are linked to various health issues, including respiratory problems, headaches, dizziness, and nausea. Prolonged exposure to certain VOCs, such as formaldehyde, has been associated with more serious health risks, including cancer.
The emission of VOCs from scented candles has been linked to adverse symptoms in university students in Saudi Arabia, with a prevalence of 24.8%, which was higher than the results reported in other countries for fragranced products, including scented candles. These symptoms included respiratory issues such as coughing and shortness of breath, as well as non-respiratory symptoms like headaches.
It is important to note that not all VOCs are harmful. Many fragrance ingredients in candles are identical to VOCs found in nature, such as those present in botanical gardens or forests. The safety of a fragrance depends on its concentration in the air. To ensure the safety of fragrances, formulas are reviewed against the standards established by the International Fragrance Association (IFRA).
Individuals with known sensitivities to specific fragrances may want to avoid scented candles or opt for candles scented with natural essential oils. Burning candles in a well-ventilated area can also help reduce the impact of any pollutants released.

Candles with high fragrance concentrations are more likely to trigger warnings
When discussing the classification of candles as hazardous materials (hazmat), it is important to consider the potential hazards associated with their fragrance concentrations. While candles are not typically considered hazardous goods in and of themselves, those with high fragrance loads can trigger warnings and may require special handling during transport. This is because certain fragrance components can be classified as hazardous under specific criteria. The key factors that determine whether a candle's fragrance concentration poses a hazard are its flashpoint and the nature of the chemicals used. A flashpoint refers to the lowest temperature at which a substance's vapours can ignite and is a critical factor in determining flammability hazards. Candles with high fragrance concentrations may have a lower flashpoint, which could lead to increased flammability and potential safety risks during transportation.
Additionally, the specific chemicals used in fragrance oils can also contribute to a candle's hazmat classification. Some fragrance components may be regulated as hazardous materials due to their potential health effects or environmental impact. For example, certain chemicals may be classified as toxic or harmful if inhaled or absorbed through the skin. If a candle contains significant concentrations of these regulated substances, it is more likely to be considered hazmat. The classification also depends on the overall composition of the candle, including the type of wax, wick, and any additional additives. The interaction between these components and the fragrance can influence the candle's burn characteristics and potential hazards.
To ensure compliance and safety, candle manufacturers and shippers must carefully consider the fragrance loads and chemical compositions of their products. Adhering to regulations and properly declaring any potential hazards are crucial to avoiding fines, delays, or safety incidents during transportation. By understanding the flashpoint, chemical composition, and potential hazards associated with high fragrance concentrations, manufacturers can make informed decisions and provide accurate information for the safe handling and transport of their candle products. This proactive approach ensures that any potential risks are mitigated, and it helps maintain a positive and responsible reputation for the candle-making industry as a whole.
It is worth noting that regulations and guidelines regarding hazardous materials can vary across different regions and countries. As such, candle manufacturers and distributors must stay informed about the specific requirements applicable to their areas. By working closely with fragrance suppliers and staying up-to-date with industry developments, candle businesses can create products that not only meet safety standards but also provide enjoyable and satisfying experiences for consumers. This balance between fragrance concentration and safety is key to maintaining the integrity of the candle-making industry and fostering trust among consumers who appreciate the beauty and ambiance that candles bring to their lives.
In summary, while candles are not inherently hazmat, those with high fragrance concentrations warrant special consideration due to potential flammability and chemical hazards. By understanding the factors that contribute to these hazards, manufacturers can make informed decisions to ensure the safe handling and transportation of their products. Staying compliant with regulations and maintaining transparency in declaring any potential risks are essential to mitigating hazards and fostering a positive reputation within the industry. With careful consideration of fragrance loads and responsible manufacturing practices, candle businesses can continue to bring their unique products to market, providing consumers with a safe and enjoyable experience.

Candles are flammable and may be classified as Dangerous Goods
Candles are not typically classified as hazardous materials, or Hazmat. However, they are often classified as Dangerous Goods due to their flammability. The specific classification of a candle depends on its chemical composition, including any additives for fragrance, colour, or gel.
The National Candle Association (NCA) states that there are no known health hazards associated with the use of scented candles. They assert that fragrances approved for candle usage do not release toxic chemicals. Furthermore, the NCA claims that all major candle waxes exhibit the same basic burn behaviour and produce virtually identical combustion byproducts, indicating that the type of wax does not significantly impact safety.
However, some studies have found that scented candles release volatile organic compounds (VOCs) both before and while being lit. VOCs can cause headaches, eye and throat irritation, nausea, and even organ damage. It is important to note that exposure to VOCs from candles can be mitigated by ensuring proper ventilation in the space where they are burned.
In terms of regulatory requirements, candles are considered 'mixtures' on a carrier (the wick) and fall within the scope of Classification, Labelling, and Packaging (CLP) regulations. These regulations require determining if a product's composition triggers any health, environmental, or physical hazards and labelling it accordingly. While candles made solely of wax are non-hazardous, additives for fragrance, colour, or gel may be hazardous and require warning labels if present at high enough concentrations.
Overall, while candles are not typically classified as Hazmat, their flammability and potential for releasing VOCs underscores the importance of safe handling and proper ventilation when burning candles.

No known health hazards are associated with scented candles
Whether or not candles are considered hazardous materials (or Hazmat) depends on their exact chemical composition. While candles made purely from wax are typically not classified as Hazmat, the fragrances, colours, and gels that are often added to them may cause them to be classified as hazardous materials.
However, no known health hazards are associated with scented candles. Validated scientific studies have shown that all major candle waxes exhibit the same basic burn behaviour and produce virtually identical combustion byproducts, both in terms of composition and amount. To date, no peer-reviewed scientific study has ever collected or analysed any emissions data on any candle wax, including petroleum-based paraffin, and proven them to be harmful to human health.
The fragrances approved for candle usage – whether synthesized or “natural” – do not release toxic chemicals. However, it is always possible that a particular fragrance might trigger a negative reaction in a very small percentage of sensitive individuals. Individuals with known sensitivities to specific fragrances may want to avoid candles of those scents.
To ensure the safety of fragrances, fragrance formulas are reviewed against the safety standards established by the International Fragrance Association (IFRA). Each ingredient in the fragrance and the finished product is required to meet the specifications set down by IFRA to be compliant with the standard. If the fragrance and product meet the standard, then the fragrance VOCs in that particular product are considered safe for human use.
The federal government, along with California and several other states, have established VOC regulations for consumer products such as candles and air fresheners. They limit the concentration of VOCs in these and many other consumer products. However, these regulations are not based on any health concerns about the VOCs themselves but instead aim to minimize the interaction between VOCs and other chemicals in our atmosphere.
