Paraffin Wax

Paraffin wax is used as a thickener for thixotropic formulas to help the mixture form gel that adheres to vertical surfaces and to reduce the evaporation of the solvents, thus prolonging the time the solvent can penetrate the paint. Cellulose-based agents, e.g., hydroxypropyl cellulose, are commonly used for mixtures that are not extremely acidic or basic; under such conditions cellulose undergoes hydrolysis and loses effectiveness, so paraffin wax or polyethylene or polypropylene derivatives, or polyacrylate gels are used.

Soy Wax

Soy wax is made by the full hydrogenation of soybean oil and chemically this gives a triglyceride, containing a high proportion of stearic acid. It is typically softer than paraffin wax and with a lower melting temperature, in most combinations. However, additives can raise this melting point to temperatures typical for paraffin-based candles. The melting point ranges from 49 to 82 degrees Celsius (120 to 180 degrees Fahrenheit), depending on the blend.

Wax Blends

Many people prefer to purchase blended waxes for several reasons:

1. The number of raw materials needed to be purchased can be minimized.
2. Both the time involved in preparing wax blends and the potential to error are greatly reduced.
3. Continuity between lots should be much better since large batches are usually prepared by the person who blends the wax.
