Soy wax is a vegetable wax made from the oil of soybeans. The melting point ranges from 49 to 82 degrees Celsius (120 to 180 degrees Fahrenheit), depending on the blend. Soy wax is available in flake and pellet form and has an off-white, opaque appearance. Its lower melting temperature can mean that candles will melt in hot weather. Since soy wax is usually used in container candles, this is not much of an issue.
The Benefits of Soy Wax
- Natural – One of the many benefits of using soy as the primary ingredient for candles is its all-natural and healthy content.
- Longer Lasting – Soy wax candles are typically long lasting compared to other types such as paraffin. The longevity of soy wax candles is largely due to its slow and cooler burning temperature.
- Cleaner Burning – All candles produce soot, but candles made from soy wax produce cleaner with very little soot. Compared to other candle types, such as paraffin, soy candles could still accumulate black soot but in a much less amount. Soy candles are, likewise, non-toxic.
Better Scents – Most soy candles retain essential oils when blended together. Soy candles burn much slower than paraffin so the scent is released into the air in a more gradual manner.
- Budget and Eco-Friendly – One of the many reasons why more and more people prefer soy wax is because it is more cost effective and cheaper than other natural waxes. It’s an eco-friendly option for making fantastically scented candles that burn slower and last longer.
- Soy wax has the tendency to expand or contract. These are effects that are natural due to the changes of temperature and the natural characteristics of soy wax. While contracting and expanding are natural occurrences of this are mostly unavoidable, it helps to keep candles in a consistently warmer (above 60 degrees) temperature. Cooler temperatures will cause shrinkage.
- Soy wax is not flexible with some types of fragrance oils. This could be remedied through testing scent oils and asking manufacturers how they work with soy wax.
- Soy wax may create frost marks in the candle or tart. There are, however, soy additives that could reduce the production of soy frost.
- Soy wax could become fussy due to humidity and temperature.
