Although typically used to describe paraffin or beeswax, wax encompasses a wide range of substances with similar characteristics. Waxes are produced from a variety of materials, including numerous plants and animals, petroleum, coal and certain synthetics. They are used for applications ranging from packaging and coating to lighting and hobby crafts. Typically, waxes incorporate multiple fatty acids into their chemical composition, usually mixed with a carbon, hydrogen, oxygen compound, although not all waxes share a common chemical makeup. However, all waxes exist in solid state at room temperature and melt at relatively low temperatures.

The main application for wax is in candles, which use an extensive assortment of waxes. For example, paraffin, also used extensively in packing applications, is a prime ingredient of commercial candles. It is an odorless, tasteless white substance that is produced from petroleum during refining. Other substances can be added to a paraffin base to produce different colors, consistencies and odors. Beeswax, carnauba wax and plant waxes are also used by candle makers, often to produce specific odors and candle types.

Waxes are also used to provide a barrier to moisture, grease and other contaminants. All waxes have a good degree of water resistance, although certain types are better suited to these applications. Paraffin is widely used in packaging applications, such as coating for paper, film and other materials (cartons, cups, etc.). It greatly enhances the holding capacity and duration of efficiency for these substrates, and provides a high degree of protection to biodegradable products. Paraffin is also used as an ozone inhibitor, as well as a lubricant in certain extrusion processes. Other waxes are used to coat molds during manufacturing operations in order to allow for easy part removal after injection. Additional applications for wax include waterproofing, food preparation, sealing and ink and hot melt production.
