What You'll Learn
Soy wax is made from soybean oil
Soy wax is an increasingly popular alternative to paraffin wax, which is derived from petroleum, coal, or shale oil. Paraffin wax is cheaper to produce but contains carcinogens and toxins that can be harmful to health. Soy wax, on the other hand, is a natural product that burns slowly and cleanly, making it a better choice for the home and the environment. It has a longer burn time and produces less soot, helping to maintain good air quality in the home.
Soy wax is often fragranced with essential oils and coloured with dyes. The wax is melted and blended with fragrances and colours, before being poured into containers with wicks. The wax is then left to cool and cure, which can take several days.
Soy wax is a sustainable product, supporting farmers and the environment. It is a popular choice for candle-makers due to its eco-friendly and non-toxic nature, as well as its superior performance compared to traditional waxes.

Soybeans are harvested, cleaned, and de-hulled
The process of harvesting, cleaning, and de-hulling soybeans is an important step in the creation of soybean candles. It ensures that the beans are free of impurities and prepares them for the extraction of their oil, which will be transformed into wax through hydrogenation. Soybean candles are known for their eco-friendliness and sustainability, and this begins with the careful harvesting and processing of soybeans.
The harvesting process typically takes place in the Midwest states of the USA, including Illinois, Iowa, and Indiana. Farmers in these states grow soybeans as a renewable resource, supporting the production of soybean candles and other soy-based products. The beans are then cleaned and prepared for the extraction of their oil, which is a key step in creating the wax for soybean candles.
The de-hulling process is crucial as it removes the outer shell of the soybean, allowing for the extraction of the oil-rich inner core. This step ensures that the beans can be transformed into fine flakes, which are ideal for oil extraction. The de-hulling process also results in leftover bean husks, which are commonly used as animal feed, further contributing to the sustainable nature of soybean candles.
Overall, the harvesting, cleaning, and de-hulling of soybeans are important steps in the creation of soybean candles. These processes ensure the purity and quality of the beans, preparing them for the extraction of soybean oil, which will be transformed into the wax that makes soybean candles unique and environmentally friendly.

Oil is extracted from soy flakes
Soy wax candles are made from soybean oil. Soybeans are harvested, cleaned, cracked open, and de-hulled to remove the outer shell. The beans are then rolled into fine flakes, which are essential for extracting the soybean oil used in making wax.
The oil is extracted from these flakes using solvents or mechanical pressing, and then hydrogenated. This process involves the introduction of hydrogen, which transforms the liquid oil into a solid wax. It changes the chemical structure of the oil, increasing its melting point and solidifying it at room temperature. This is a critical step in creating a wax with the ideal consistency for candle-making.
The hydrogenation process converts some of the fatty acids in the oil from unsaturated to saturated. This significantly alters the melting point of the oil, ensuring it becomes solid at room temperature. Without this process, the oil would remain liquid, making it unsuitable for candle-making.
Soy wax is derived from soybean oil through this process of extraction and hydrogenation. The oil extraction from the soy flakes is a key step in ensuring the wax takes on the desired characteristics for candle-making.

Hydrogenation converts oil to wax
Soy wax candles are made from soybean oil. Soybeans are harvested, cleaned, cracked, de-hulled, and rolled into flakes. The oil is then extracted from the flakes and undergoes hydrogenation.
Hydrogenation is a process where hydrogen is introduced to transform the liquid oil into a solid wax. This process changes the chemical structure of the oil, increasing its melting point and solidifying it at room temperature. Specifically, hydrogenation converts some of the fatty acids in the oil from unsaturated to saturated. This dramatically alters the melting point of the oil, making it solid at room temperature.
The hydrogenation process is critical as it creates a wax with the ideal consistency for candle-making. Without hydrogenation, the soybean oil would remain liquid at room temperature and would not be suitable for candle-making.
After hydrogenation, the soy wax is ready for the next steps of candle-making. The wax is melted and blended with fragrances and dyes. The melted wax is then poured into a container with a wick and left to cool and cure. During this time, the wax solidifies, and the fragrance fully integrates, ensuring a clean and consistent burn.
Soy wax candles offer several advantages over traditional paraffin candles. They burn cleaner, produce less soot, and last longer. Additionally, soy wax is made from renewable and biodegradable resources, making it a more sustainable and eco-friendly alternative to paraffin wax.

Candle wicks are prepped and wax is poured
Soy candles are made from soy wax, which is derived from soybean oil. Soy wax is a vegetable wax made from soybeans, a legume grown primarily in the Midwest USA. Soy wax candles are known for their clean and slow burn, making them a popular and eco-friendly alternative to traditional paraffin wax candles.
Now, let's delve into the process of preparing the candle wicks and pouring the wax:
Candle Wicks are Prepped
The first step in preparing the candle wicks is to place them in the chosen candle containers. This step is crucial, as it ensures that the wick remains centred and secure during the wax pouring process. The wicks are carefully positioned in the centre of the containers to allow for an even burn once the candles are lit.
Wax is Poured
Once the wicks are in place, it's time to melt the soy wax. Soy wax flakes or pellets are placed in a boiler and heated to a temperature between 175°F and 185°F (80°C and 85°C). This temperature range ensures that the wax completely melts and creates a smooth, even liquid. At this stage, candle makers can add fragrances and dyes to customise the candles. Fragrance oils or essential oils can be used, along with dye blocks to achieve the desired colour.
The melted wax mixture is then carefully poured into the containers, encasing the wicks. It is important to ensure an even pour so that the wax sets uniformly around the wick. This step requires precision and a steady hand to avoid spilling or creating air bubbles in the wax.
Cooling and Curing
After the wax is poured, the candles are left to cool and cure. This process can take several hours or even days. During this time, the liquid wax gradually solidifies, and the fragrance oils or dyes fully integrate, resulting in a consistent and aesthetically pleasing candle. Allowing adequate curing time ensures the best scent throw and optimal burning performance.
Soy candles offer a longer burn time compared to traditional candles, and their clean-burning properties make them a popular choice for those seeking eco-friendly and non-toxic alternatives. The process of preparing the wicks, pouring the wax, and curing the candles requires attention to detail and patience, resulting in elegant and sustainable lighting options.
