Soy wax is a natural, renewable wax made from soybeans. It is widely used in candle making due to its clean-burning properties, excellent fragrance retention, and eco-friendly nature. Understanding how soy wax is made can help candle makers select the best type for their projects, whether container candles, pillars, or blended waxes.
Step 1: Harvesting Soybeans
Soy wax production begins with high-quality soybeans. After harvesting, the beans are cleaned and de-hulled to remove impurities.
Step 2: Extracting Soybean Oil
The soybeans are then mechanically pressed or solvent-extracted to obtain soybean oil. This oil is edible but can also be used as a raw material for candle wax.
Step 3: Hydrogenation Process
The liquid soybean oil is hydrogenated to transform it into a solid wax. Hydrogenation changes the chemical structure of the oil, raising the melting point and giving it the hardness needed for candles.
Step 4: Cooling and Solidifying
After hydrogenation, the wax is cooled and solidified. It can be formed into flakes, pellets, or blocks depending on the intended application.
Step 5: Refining and Filtering
The wax is refined to remove impurities and ensure a smooth, creamy texture. This process is important for producing candles with uniform burning and excellent fragrance throw.
Step 6: Optional Blending
Many manufacturers blend soy wax with additives like coconut wax, beeswax, or palm wax to modify hardness, melting point, or fragrance retention. For example:
- 52°C flakes for container candles
- 58°C pellets for pillars and molded candles
- 68°C Indian soy wax for high-melting-point applications
- 464 U.S. soy wax for versatile container or blended waxes
Advantages of Soy Wax:
- Clean-burning with low soot
- Biodegradable and renewable
- Excellent fragrance retention
- Smooth and creamy texture for easy coloring and pouring
