Paraffin wax is a versatile, petroleum-derived wax used in candles, cosmetics (moisturizers, lip balms), food coatings (shiny finishes, moisture retention for produce), and pharmaceuticals (ointments, arthritis therapy), as well as for lubrication, waterproofing, electrical insulation, and making crayons and polishes. Its ability to melt at low temperatures and form a protective, moisturizing layer makes it useful in beauty treatments for hands and feet and for heat therapy to relieve joint pain
