Stearic acid, also known as stearin, is a long-chain fatty acid often used in candle-making. Its primary property is to raise the melting point of the wax mixture, making the resulting candle harder and more durable.
The derivation of stearin from rendered animal fat aided the industry's transition from tallow to paraffin. Paraffin became popular because it cost less to produce and burned cleaner than tallow. However, its lower melting point--between 120 and 140 degrees Fahrenheit--caused problems. The hardening effect of stearin, with its melting point of up to 160 degrees Fahrenheit, made paraffin a much more viable option. Today, most commercially produced candles are made from a stearin/paraffin mixture.
