- Food industry: Paraffin wax is used as a coating for fruits and vegetables to enhance their appearance and prolong shelf life.
- Industrial applications: Paraffin wax is used in various industrial processes, such as lubrication, insulation, and as a component in wax blends.
Origins and Extraction of Paraffin Wax
Paraffin wax is derived from crude oil, a fossil fuel formed from the remains of ancient plants and animals. Crude oil is typically found in underground reservoirs and extracted through drilling.
Crude oil refining process
To obtain paraffin wax, crude oil undergoes a refining process known as distillation. This process involves heating the crude oil to separate it into various components based on their boiling points.
Distillation and fractionation
During distillation, the crude oil is heated in a distillation tower. As the temperature increases, the different hydrocarbon components vaporize at different temperatures. The vaporized components are then condensed and collected at different levels of the tower.
Fractionation, a subsequent step, involves further separation of the collected fractions based on their molecular weight and boiling points. This process helps to isolate the desired range of hydrocarbons for paraffin wax production.
Paraffin wax production
Once the desired fraction is obtained, it undergoes additional processing steps to remove impurities and refine its properties. This may involve treatments such as solvent extraction, dewaxing, and bleaching. Finally, the refined product is cooled and solidified to produce paraffin wax.
Natural Sources of Paraffin Wax
Occurrence in nature
Paraffin wax is not naturally occurring in its refined form. However, its primary component, long-chain hydrocarbons, can be found in various natural substances, including crude oil, plants, and animals.
Certain vegetable oils, such as soybean oil, can be hydrogenated to produce a wax-like substance that resembles paraffin wax. This vegetable-based wax is often used as a natural alternative to paraffin wax in some applications.
Beeswax and lanolin are examples of waxes produced by animals that exhibit similar characteristics to paraffin wax. While not chemically identical, they are often compared to paraffin wax due to their physical properties and uses in various industries.
Synthetic Paraffin Wax
Synthetic paraffin wax, also known as fully refined paraffin wax, is manufactured through a process called Fischer-Tropsch synthesis. This method involves the conversion of carbon monoxide and hydrogen gases into long-chain hydrocarbons, which are then purified and solidified.
To enhance specific properties or create specialized variations of paraffin wax, chemical additives can be incorporated during the manufacturing process. These additives may include colorants, fragrances, antioxidants, or UV stabilizers.
Synthetic paraffin wax finds applications in industries where a higher degree of purity, consistency, or specialized characteristics are required. It is commonly used in the production of high-quality candles, pharmaceuticals, and cosmetics.
Controversy Surrounding Paraffin Wax
Paraffin wax’s extraction and production processes are associated with environmental concerns. The reliance on fossil fuels for crude oil extraction contributes to carbon emissions and other environmental impacts associated with oil drilling and refining.
When paraffin wax is burned, it can release potentially harmful substances such as volatile organic compounds (VOCs) and soot particles. Prolonged exposure to these emissions may pose health risks, particularly for individuals with respiratory conditions or sensitivities.
Comparison with other waxes
Paraffin wax is often compared to alternative waxes, such as beeswax, soy wax, coconut wax, and palm wax, in terms of environmental impact, health considerations, and performance. These comparisons help consumers make informed choices based on their specific needs and values.
Paraffin Wax vs Natural Waxes
Beeswax, derived from the honeybee, offers a natural alternative to paraffin wax. It has a higher melting point and a distinct aroma. Beeswax is often preferred for its more sustainable sourcing and potential health benefits, such as its ability to emit negative ions when burned.
Soy wax is made from soybean oil and is commonly used as an alternative to paraffin wax in candle-making. It is considered to be a more environmentally friendly choice due to its renewable source and lower emission of soot when burned.
Coconut wax is derived from coconut oil and is a natural option for candle production. It has a clean burn and good scent throw, and its sourcing from coconuts makes it a renewable and sustainable choice.
Palm wax is obtained from palm oil and is another natural wax option. It has a higher melting point, a smooth texture, and is often used in the production of container candles. Concerns have been raised regarding the sustainability of palm oil production, leading some consumers to seek alternative options.
