Wax emulsions based on beeswax, carnauba wax and paraffin wax are used in creams and ointments. The emergence of soybean waxes with varying properties and melt points has led to the use of vegetable wax emulsions in applications such as paper coatings, paint and ink additives, and even wet sizing for pulp and paper applications.
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 ...
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [1] MDF is generally denser than plywood.
Wax deposition or paraffin deposition refers to the accumulation of paraffin wax on the surface of a substance, typically a liquid or gas. This can occur in a variety of contexts, including the production and transport of oil and natural gas, the refining of petroleum products, and the storage and transport of chemicals.
Paraffin waxes are mixtures of saturated n- and iso- alkanes, naphthenes, and alkyl- and naphthene-substituted aromatic compounds. A typical alkane paraffin wax chemical composition comprises hydrocarbons with the general formula C n H 2n+2, such as hentriacontane, C 31 H 64. The degree of branching has an important influence on the properties.

Natural wax was largely replaced for the making of waxed paper (or paraffine paper) after Herman Frasch developed ways of purifying paraffin and coating paper with it in 1876. [2] Waxed paper is commonly used in cooking for its non-stick properties, and wrapping food for storage, such as cookies , as it keeps water out or in.
