Soy wax is a new alternative to paraffin wax that is cost effective. Soy wax is also made from a renewable source. Soy wax is natural -Soy wax is a favorite of environmentally conscious people because it is made from a renewable source and is not made from petroleum. Burning soy candles does not increase the CO2level in the atmosphere. However, some suppliers may add some synthetic wax or paraffin to their soy wax to adjust its physical characteristics. Soy candles last longer- Some suppliers claim that soy candles can last up to 50% longer than paraffin candles. Our tests could not confirm this claim. Wax spills are easy to clean - It's very difficult to remove paraffin wax from furniture or textiles.Soy wax spills can easily be cleaned up with hot soapy water. Soy candles produce less soot - Soot should be avoided because it is very unhealthy and caneventually coat furniture and walls. Soy candles produce about 90% less soot than paraffin candles. Scented soy candles distribute more flavor - The incorporation of soybean oil lowers the melting point of the candle, which translates into cooler burning candles and faster scent dispersion. The lower melting point of soy wax results in a larger size of the liquid wax pool around the candle wick. It is from this liquid wax pool that the essential oils evaporate into the atmosphere.
