Paraffin Wax

Paraffin wax—a very inexpensive wax—is most widely used across candle brands, says Fitchl, because it can hold a high amount of fragrance and color. It also comes in various melt points, making it suitable for making many different types of candles, from containers to pillars. That said, it’s not considered the most eco-friendly type of candle wax, since it’s made from a byproduct of the oil industry, she explains. Another downside: If not properly cared for, a paraffin wax candle will create soot.
