parafiin

Paraffin is a term used for a group of hydrocarbon products derived from petroleum or coal tar. In different regions it can refer to different substances: paraffin wax, a solid used in candles and coatings, and liquid paraffin (paraffin oil), a mineral oil used as a lubricant and laxative in some contexts. The word also appears in some countries as kerosene.

Paraffin wax and liquid paraffin are produced during petroleum refining. The crude oil is separated into fractions by distillation; the wax fraction is further treated to yield paraffin wax, a solid at room temperature with a pale, waxy appearance. Liquid paraffin is a colorless, odorless oil consisting of saturated hydrocarbons of moderate chain length.

Paraffin wax has many uses: candles, decorative coatings, cosmetics (lip balms, creams), food packaging, and protective coatings. Liquid paraffin is used as a lubricant in industry, as a cosmetic ingredient, and in medicine in some countries as a laxative or emollient, though medical use requires appropriate purity and regulation.

Safety and environmental notes: Paraffin products are flammable and should be stored away from heat sources. They are generally chemically inert but can cause skin irritation in some individuals and are not soluble in water. Waste should be disposed of in accordance with local regulations; spills should be contained to prevent environmental contamination.
