Candle additives are substances added to the wax to enhance specific properties or improve overall performance. They can be used to change the colour, scent, burn time, and stability of a candle. While additives can make candles more visually appealing, not all are safe to use. For example, dried flowers, leaves, herbs, and other flammable materials embedded in the wax near the wick pose a significant fire hazard. Popular additives include stearic acid, vybar, paraflint, and various dyes.

What You'll Learn
Additives can enhance candle appearance and performance
Additives can be used to enhance the appearance and performance of candles. They are substances added to the candle wax to improve specific properties or overall performance.
Additives can be used to enhance the colour of candles. Dyes, for example, are added to give candles their vibrant colours. They come in various forms, such as liquid dyes, dye chips, and dye blocks. It is important to note that too much dye can affect the candle's burn quality, causing it to burn unevenly or produce excessive soot.
Additives can also be used to improve the scent of candles. Fragrance oils, for example, are typically made of a blend of natural and synthetic compounds. They can have different flashpoints, which affect when the scent is released during the burning process. However, fragrance oils can also cause colours to fade or change. To prevent this, a UV inhibitor can be added to protect the colours of the candles from fading due to UV light exposure.
Other additives can be used to improve the hardness and burn quality of candles. For example, stearic acid is a long-chain fatty acid that can be derived from animal or plant sources. It has a high melting point, which contributes to its ability to harden candles, improving their durability and burn quality.
Finally, some additives are used to create unique features in candles. For example, mica, botanicals, and glitter can be added to make candles more aesthetically pleasing. However, it is important to note that not all additives are safe to use, and some flammable additives, such as dried flowers and herbs, can pose a fire hazard.

Some additives can be unsafe
Candle additives are substances added to the candle wax to enhance specific properties or improve overall performance. They can affect various aspects of a candle, such as its colour, scent, burn time, and stability. However, not all additives are safe to use in candles.
According to a report from the National Candle Association (NCA), candles with dried flowers, leaves, herbs, and other flammable materials embedded in the wax near the wick pose a significant fire hazard. In their report, two out of three candles with botanicals embedded on the surface of the wax ignited on the first burn, with one candle experiencing a "flashover event" where the entire surface of the candle lit on fire.
It is recommended to position dried flowers as far away from the wick as possible immediately after pouring your candle to prevent them from catching fire once the wax melts.
Another additive to be cautious of is fragrance oils. While they enhance the scent of candles, they can also cause colours to fade or change. UV Stabilizer can be added to prolong the fading process, but it will not completely eliminate it.
Additionally, the use of too much dye can impact the candle's burn quality, causing it to burn unevenly or produce excessive soot. It is recommended to use candle-specific dyes sparingly to achieve the desired colour.
When adding items such as a surprise ring or other gifts embedded in the candle, it is crucial to ensure they are non-flammable and will not melt, such as plastic. Wrapping the item in foil can help prevent it from being covered in wax.
In conclusion, while candle additives can enhance the appearance and performance of candles, it is important to be aware of potential safety hazards. It is recommended to test different combinations of additives to ensure the desired results and avoid any unsafe outcomes.

Additives can be used to improve colour
Candle additives are substances added to candle wax to enhance specific properties or improve overall performance. Additives can be used to improve colour in several ways.
Firstly, candle dyes are used to give candles their vibrant colours. They come in various forms, such as liquid dyes, dye chips, dye blocks, and dye flakes. Most candle dyes are aniline-based, meaning they are derived from coal tar and are highly concentrated. They should be used sparingly to achieve the desired colour. It is important to note that not all dyes and colorants can be used in candles. For example, food colouring does not blend or bind with wax, and crayons contain insoluble pigments that do not fully dissolve, which can clog the wick.
Secondly, Vybar, a polymer additive, can be used to improve the appearance of candles and enhance dye colours. It increases the opacity of the wax, making the colours appear more vibrant.
Thirdly, UV inhibitors such as UVasorb can be added to candles to protect them from fading due to exposure to UV light rays. This is particularly useful for candles that will be displayed for extended periods.
Finally, it is worth mentioning that fragrance oils can also affect the colour of candles. Some fragrance oils are naturally darker in colour, and certain essential oils can change the colourant's finished hue over time. Therefore, it is important to test the colour before adding fragrance and to store UV-sensitive dyes away from direct sunlight.

Additives can be used to improve scent
Additives can be used to improve a candle's scent, as well as enhancing its colour, burn time, and stability.
Vybar is a type of polyethylene wax with a low molecular weight that can easily mix with other waxes to improve their properties. It is used primarily to aid in fragrance oil retention, although it also increases opacity and enhances dye colours. When using vybar, wax can hold more fragrance oil without the oil separating from the mixture. This enables the candlemaker to put two or three times as much fragrance oil into their mixture, resulting in a much better scent throw. However, too much vybar can trap the fragrance in the candle, reducing its scent throw.
There are two types of vybar: vybar 103 and vybar 260. Vybar 103 is used for harder, higher-melting-point waxes such as pillar and votive waxes, while vybar 260 is used for softer, lower-melting-point waxes like container waxes. The recommended usage is 1/4 to 1/2 teaspoon per pound of wax, but this will vary depending on the application.
Another additive that can improve scent throw is paraffin (mineral) oil. This additive gives candles a mottled (snowflake) appearance by raising the percentage of oil in the wax. This effect often occurs by accident when there is too much fragrance oil in the wax or not enough vybar in the blend. However, it can also be achieved intentionally by deliberately increasing the percentage of oil in the wax.
In addition to vybar and paraffin oil, other additives such as stearic acid and UV inhibitors can also enhance a candle's scent throw. Stearic acid, derived from animal or plant sources, has a high melting point and contributes to the hardening of candles. UV inhibitors, on the other hand, protect the colours of candles from fading due to UV light exposure, ensuring that scented candles retain their vibrant appearance even when displayed for extended periods.

Additives can be used to improve burn time and stability
Vybar is another additive that can be used to improve burn time. It is a type of polyethylene wax with a low molecular weight, allowing it to easily mix with other waxes and improve their properties. Vybar helps candles hold on to their colours and fragrances. It increases the opacity of the wax and enhances dye colours. It also helps the wax hold more fragrance oil, improving the candle's scent throw.
Another way to improve burn time is by adding beeswax. Like stearic acid, beeswax also acts as a hardening agent, making the candle more durable and increasing its opacity.
To prevent candles from fading or discolouring due to sunlight exposure, UV inhibitors can be added. These protect the colours of the candles from both artificial and natural light, ensuring they remain vibrant for longer.
