Candles are a popular way to enhance the ambiance of a room and create a cozy atmosphere. However, with their open flames, they can also pose safety risks, especially when it comes to flammability. While candle wax itself is not highly flammable, the additives used to create fragrance and color can significantly impact a candle's burning characteristics, potentially increasing its flammability. Due to this, candles are often considered flammable goods during transportation and may be classified as dangerous goods. To ensure safety, it is crucial to understand how different additives interact with the wax and to follow relevant regulations and safety standards, such as proper labeling and warning statements, to prevent accidents and protect consumers.

Candles are flammable goods
Candles are considered flammable goods. While candle wax itself is not highly flammable, the additives used to create colour and fragrance can be. These additives can alter the burning characteristics of the wax, affecting the burn rate and flame size. For example, too much fragrance oil can increase a candle's flammability, leading to a larger, potentially unsafe flame.
The Federal Hazardous Substances Act (FHSA) in the United States lists candles made with metal-cored wicks as potentially dangerous due to their lead content. Candles with wicks containing more than 0.06% lead are banned from the US market.
In the UK, candles are considered 'mixtures' and are therefore within the scope of Classification, Labelling and Packaging (CLP). This means that if a candle contains hazardous materials, it must be labelled as such. However, it is unlikely that a CLP label relating to flammability will be required for candles, as they are not likely to meet the classification criteria for this to apply.
When shipping candles, it is important to refer to the relevant regulations and requirements for transporting dangerous goods. In the United States, the Federal Hazardous Materials Regulations require shippers to appropriately categorize, package, mark, and label hazardous items before shipping. Candles are typically classified as Class 4 flammable solids, along with items like matches.
Overall, while candles are considered flammable goods, the level of flammability can vary depending on the type of wax, wick, and additives used. It is important for candle manufacturers and sellers to be aware of the relevant regulations and safety standards to ensure their products are safe for consumers.

Candle composition and safety
Candles are made primarily of wax, which acts as the fuel source for the flame. Paraffin wax, derived from petroleum, is the most commonly used type due to its affordability and versatility. It is a complex mixture of hydrocarbons, with different molecular weights and structures determining its melting point, hardness, and other physical properties. Soy wax, made from soybean oil, is a popular eco-friendly alternative, known for its clean-burning and renewable nature.
The wick is the engine that drives the candle's combustion process. Made from braided cotton or linen fibres, the wick draws liquid wax up from the candle's reservoir and delivers it to the flame. The size and composition of the wick play a crucial role in determining factors such as burn rate, flame size, and the intensity of the candle's glow. Candle wicks are typically treated with various substances to enhance their performance, such as borax or boric acid to increase rigidity and prevent sagging during burning. Some wicks are also coated with metals like zinc or tin to improve stability and reduce mushrooming—the formation of carbon deposits at the tip.
While candles are primarily composed of non-hazardous wax, they often contain additives for fragrance and colour, which may be hazardous at high concentrations. These additives can alter the chemical composition of the wax, affecting its melting point, viscosity, and combustion characteristics. Some additives may produce soot, smoke, or other byproducts when burned, reducing the overall quality of the flame and burn time. The greater the concentration of fragrance, the more likely it is to trigger warnings. To ensure safety, fragrance formulas are reviewed against standards established by the International Fragrance Association (IFRA).
To minimise the risk of accidents, it is essential to follow basic safety guidelines when using candles. Keep candles away from flammable materials, never leave them unattended, and always trim the wick to the recommended length before each use. Using appropriate candle holders, such as glass or metal containers, can also help prevent fires and injuries by enclosing the flame. Always extinguish candles properly by using a candle snuffer or a metal lid to smother the flame and prevent hot wax from splattering.

Candle regulation in the US
Candles are considered decorative pieces and works of art, but they are also potential health and safety hazards. Candle manufacturers and importers in the United States must adhere to various regulations, safety standards, and compliance requirements.
The Federal Hazardous Substances Act (FHSA) lists candles with metal-cored wicks as products that might be banned due to their dangerous nature. The FHSA bans these products from the US market unless they do not exceed the maximum allowable lead limit of 0.06% of the total weight of the metal core.
The American Society for Testing and Materials (ASTM) has published several standards for importers and manufacturers to follow when producing candles for sale in the US. ASTM F1972 establishes standard terms and definitions for candles and associated products, while ASTM F2058 covers requirements for the placement of fire safety information. ASTM F2417 provides minimum safety requirements to reduce deaths, fires, and injuries, and ASTM F2601 covers candle accessories.
The National Candle Association (NCA) has also played a role in creating a set of industry standards to address the increase in fires caused by candles. These standards are published through ASTM International and outline legal requirements.
California Proposition 65 is a state regulation that restricts the use of toxic chemical substances in consumer products, including candles. Most products imported and marketed in the United States, including candles, must also contain a permanent country of origin marking on the product or its packaging.
To ensure their candles are safe to use, importers and manufacturers must test their products according to relevant standards. Lab testing may include specifications such as the standard test method for collection and analysis of visible emissions from burning candles.

Candle wax and flammability
The flammability of candles depends on their exact chemical composition. Candles are considered 'mixtures' on a carrier (the wick) and are therefore deemed to be within the scope of Classification, Labelling and Packaging (CLP). This involves determining if a product triggers any health, environmental, or physical hazards and labelling the product accordingly.
Candles are primarily made of wax, which is non-hazardous and does not require classification. However, candles often contain additives for fragrance and colour, which may be hazardous and, if present in high enough concentrations, could require warning statements or pictograms. The main cause for concern relates to sensitisation, where the presence of a particular substance at very low concentrations can trigger labelling requirements. If a candle contains any sensitising fragrance ingredient at more than 0.1%, the label should state: "Contains (name of fragrance/s)".
The greater the concentration of fragrance in the candle, the more likely it will trigger one or more of these warnings. Other human health hazards, such as skin irritation, are unlikely, but this needs to be considered on a case-by-case basis by suppliers who know the full composition of the candle, including fragrances and colourants.
It is unlikely that a CLP label relating to flammability will be required for candles, as they are not likely to meet the classification criteria for this to apply. However, candles can be considered flammable, especially with essential oils/additives for fragrance and colour at high enough concentrations.
The wax itself is the fuel for the candle. There are two main categories of candle wax: paraffin and beeswax. Paraffin wax is a petroleum product that is super flammable but only in its gaseous state. It has a low melting point, so it will not burn in its solid or liquid state. Beeswax, on the other hand, burns at a lower temperature than paraffin wax.

Candle wicks and safety
Candles are considered 'mixtures' on a carrier (the wick) and are therefore deemed to be within the scope of Classification, Labelling, and Packaging (CLP). While candle waxes are non-hazardous and do not require classification, candles often contain additives for fragrance and colour, which may be hazardous and require warning statements or pictograms. The greater the concentration of fragrance in the candle, the more likely it will trigger warnings.
The purpose of a wick is to deliver fuel (wax) to the flame. The wick draws the liquefied wax up into the flame to burn. Different wick sizes allow for different amounts of fuel to be drawn into the flame. Too much fuel and the flame will flare and soot; too little fuel and the flame will sputter out. The type of wax used in a candle, as well as the candle's size, shape, colour, and fragrance materials all impact wick choice. Selecting the correct wick is critical to making a candle that burns cleanly and properly. Most high-quality wicks are made from braided, plaited, or knitted fibres to encourage a slow and consistent burn.
There are many different types of wicks, including flat wicks, square wicks, and cored wicks. Flat wicks are usually made from three bundles of fibre and are very consistent in their burning. They are the most commonly used wicks and are often found in taper and pillar candles. Square wicks are braided or knitted wicks that curl in the flame and are more rounded and robust than flat wicks. They are preferred for beeswax applications and can help inhibit wick clogging. Cored wicks use a core material to keep the wick straight or upright while burning. The most common core materials include cotton, paper, zinc, or tin.
Wooden wicks have become popular in recent years for their visual aesthetic and the soft crackling sound they create. They are available in various shapes and materials, including 100% wood, semi-wood, fibrous material, or cotton and wood combinations. Another type of wick is the CD series, which are flat braided wicks with a special paper filament woven around them. These wicks are designed to promote a maximum and consistent burn while ensuring a wick-trimming flame posture. The ECO series is a flat, coreless cotton wick braided with thin paper filaments to improve rigidity and reduce "afterglow" and smoke.
