There has been much debate over the “best” wax for candles.
There is a common perception that soy wax is somehow superior, (being “natural”) but also due to its appearance: soy wax has a creamy opaque texture, whereas paraffin is whiter and slightly translucent. Soy candles tend to burn slower than paraffin ones and require a higher percentage of fragrance to create a good scent – therefore are usually more expensive to produce.
However, The National Candle Association has provided the following statements:
All waxes are primarily hydrocarbons, whether of animal, vegetable, or petroleum origin. The chemical composition of all candle making waxes is similar, and all candle waxes burn in the same manner.
