Paraffin represented a major advance in the candle-making industry because it burned cleanly and was cheaper to manufacture than other candle fuels such as beeswax and tallow. Paraffin wax initially suffered from a low melting point. This was remedied by adding stearic acid. The production of paraffin wax enjoyed a boom in the early 20th ...
Candle moulding machine in Indonesia circa 1920. Candle making was developed independently in a number of countries around the world. [1]Candles were primarily made from tallow and beeswax in Europe from the Roman period until the modern era, when spermaceti (from sperm whales) was used in the 18th and 19th centuries, [2] and purified animal fats and paraffin wax since the 19th century.

What the candle science shows. When you burn a paraffin candle, it releases volatile organic compounds, or VOCs — gases that easily and quickly vaporize into the air at room temperature, said Dr ...
Candles were also made from stearin (initially manufactured from animal fats but now produced almost exclusively from palm waxes). [37] [38] Today, most candles are made from paraffin wax, a byproduct of petroleum refining. [39] The hydrocarbon C 31 H 64 is a typical component of paraffin wax, from which most modern candles are produced.
Many solid alkanes find use as paraffin wax, used for lubrication, electrical insulation, and candles. Paraffin wax should not be confused with beeswax, which consists primarily of esters. Alkanes with a chain length of approximately 35 or more carbon atoms are found in bitumen (asphalt), used (for example) in road surfacing.
Microcrystalline waxes are a type of wax produced by de-oiling petrolatum, as part of the petroleum refining process. In contrast to the more familiar paraffin wax which contains mostly unbranched alkanes, microcrystalline wax contains a higher percentage of isoparaffinic (branched) hydrocarbons and naphthenic hydrocarbons.
