Soy wax candles have many benefits which is why many candle makers have turned to making only soy wax for their creations. It is also the reason that many candle enthusiasts choose to buy and use soy over candles made from other types of wax. Soy can be a terrific medium to use for candles, however, it’s important to read the labels, or to purchase from a trusted brand, such as BWG Botanics, in order to understand exactly what you’re getting.
