Paraffin Wax
Definition
Paraffin wax is a soft, colorless or white solid wax derived from petroleum, coal, or shale oil that consists primarily of straight-chain saturated hydrocarbons (alkanes), typically containing 20–40 carbon atoms. It is commonly used in various applications due to its chemical stability, low reactivity, and ease of molding.
Physical and Chemical Properties
- Melting point: Typically between
46°Cand68°C - Insoluble in water, but soluble in ether, benzene, and certain esters
- Odorless and tasteless in pure form
- Low thermal conductivity and low reactivity
- Burns with a clean, smokeless flame
Common Uses
- Candle making: One of the most popular materials used in candles
- Cosmetics: Found in lotions, creams, and ointments for its moisturizing effect
- Food industry: Used as a coating for fruits and candy to preserve freshness and shine
- Packaging and sealing: Acts as a water barrier and protective coating
- Therapeutic applications: Used in heat therapy treatments for arthritis and joint pain
Health and Safety Note
Although generally considered safe, inhaling fumes from burning paraffin wax may release volatile organic compounds (VOCs). In poorly ventilated spaces, this can be a concern. Always use candles or wax products in well-ventilated areas.
