Soy wax is the most popular type of vegetable wax in candle making. Soy wax is derived from the soy bean and is therefore 100% natural. It is a renewable, natural alternative to traditional paraffin wax. As there is little impact on our environment using this wax, finished candles can be marketed as a natural product. Soy wax has a luxurious creamy colour. The negatives for this wax is that the scent throw is not quite as strong as in paraffin, and wicking can be difficult in larger containers.
