Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]

Carving wax is a smooth, non-brittle wax designed for carving and/or machining. Although the formulas for most commercial waxes are proprietary, most suppliers will state that hard waxes are some blend of waxes and plastics. This family of waxes has a hardness and consistency of plastic or softer wood. They can be cut or carved with knives ...
Typical microcrystalline wax crystal structure is small and thin, making them more flexible than paraffin wax. It is commonly used in cosmetic formulations. [2] Microcrystalline waxes when produced by wax refiners are typically produced to meet a number of ASTM specifications. These include congeal point (ASTM D938), needle penetration (ASTM ...

Oil waxing occurs when heating oil begins to gel, and before it has become too viscous to flow at all in the heating system oil piping, wax particles (wax platelets or little spheres of wax or in some articles, alkane "wax crystals") have already begun to form in the fuel.
The best-known animal wax is beeswax, used in constructing the honeycombs of beehives, but other insects also secrete waxes. A major component of beeswax is myricyl palmitate which is an ester of triacontanol and palmitic acid. Its melting point is 62–65 °C (144–149 °F). Spermaceti occurs in large amounts in the head oil of the sperm whale.
Strictly speaking a wax emulsion should be called a wax dispersion since the wax is solid at room temperature. However, because the preparation takes place above the melting point of the wax, the actual process is called emulsification, hence the name wax emulsion. In praxis, wax dispersion is used for solvent based systems.
