These traits make soy candles a popular choice in households with young children or pets. Safety around kids is a huge concern. Soy wax is also easier to clean up than some other waxes. This can be a tremendoous advantage during the holidays. You don't want your nice holiday tablecloth ruined. Soy candles tend to be more expensive than paraffin. However this cost is made up for by a longer burning life. Soy candles are also much cheaper than other candles since soy wax can be readily and easily produced to meet demand. This is greatly beneficial for environmental reasons. You can even get some candles that are partially made from recycled materials. For people who make their own candles, one of the primary advantages of soy candles is that soy wax has a relatively low melting point. This makes it much easier to work with. Soy wax is also a great medium for essential oil. The slow burning time of these candles allows them to slowly release essential oils over a number of hours so the scent is realeased gradually. More creative people can embed objects like flowers in their soy candles. Use your imagination.
