The recent years have seen a growing demand for soy candles. These candles are made from soy wax, which contains hydrogenated soybean oil as its chief ingredient. Soy wax was developed in 1992 by an American candle-maker named Michael Richards. He was looking for a cheaper material that could be used in place of beeswax for making candles. Using a blend of vegetable oils, he succeeded in creating an alternative to beeswax. Soy candles were first launched in the market in 1995 by the Body Shop chain of stores. Being inexpensive and stylish, they gradually gained popularity. Soy candles quickly found their way to the supermarkets and specialty stores across the nation.

Soy candles are available in a variety of shapes, sizes, and scents. Many candle makers offer custom made candles to suit the preferences of their customers. Soy candles are ideal for home, office, and spas. These candles, equipped with special scents, are often used for aromatherapy. Soy candles can be easily made at home. The ingredients necessary for making soy candles are available in most stores. The materials are even available from craft supply Web sites and in hobby shops. The popularity of these candles chiefly rests on their natural ingredients, which are biodegradable. They are therefore preferred over paraffin-based candles, which are environmentally more damaging.

Soy candles have many more advantages over paraffin candles. They burn 35 to 50 percent longer. Their low melting point assures slower and cooler burning, which helps in the better distribution of fragrance. These candles produce less soot, making them a healthier option. Moreover, these candles do not increase the carbon dioxide level of the atmosphere, making them more attractive to environmentally conscious people. Compared to paraffin candles, their non-toxic nature causes fewer allergies. They are therefore perceived as more child- and animal-friendly. Another major factor in the popularity of soy candles is the relative ease with which their spills can be cleaned. While paraffin wax is difficult to remove from furniture or clothes, soy wax can be easily cleaned using hot, soapy water.
