پارافین جامد

Paraffin (solid), commonly referred to as paraffin wax, is a white or colorless soft solid derived from petroleum, coal, or shale oil. It consists of a mixture of saturated hydrocarbons and is widely used in candles, coatings, cosmetics, and packaging.

🏭⚗️ Production
Paraffin wax is produced by refining lubricating oil stocks from crude oil. The process includes dewaxing by chilling and filtering, followed by further purification steps such as solvent refining or hydrotreating to obtain high-purity solid paraffin.

🔬 Properties
Paraffin wax is a soft, odorless, tasteless, white or slightly translucent solid with a melting point typically between 46 °C and 68 °C. It is insoluble in water but soluble in ether, benzene, and certain esters. It has low thermal conductivity, making it a good insulator, and it is chemically inert under normal conditions. It is flammable and burns with a smoky flame.

🧪 Applications
• Candle manufacturing is one of its primary uses due to its burn stability and moldability.
• Used in cosmetics and personal care (e.g. in skin-softening treatments, ointments, and lip balms).
• Applied as a coating for food packaging, cheese preservation, and moisture barriers.
• Employed in industrial uses such as electrical insulation, lubricants, and anti-corrosion coatings.
• Also used in therapeutic heat treatments and as a component in crayons and polishes.
