Paraffin waxes in a solid state are usually white, translucent, tasteless and odorless. They are hard, relatively brittle and have a slightly dry feel. In a molten state, paraffin waxes are clear, colorless liquids of low viscosity. When melted, these waxes increase in volume by about 5-8%, resulting in a decrease in density. Paraffin will react at high temperatures with either oxidizing or halogenating agents. This reaction produces either fatty acids and hydroxy acids or halogen substitution products respectively. Although paraffin has many useful characteristics, most commercial applications are based on its resistance to water and vapor and its glossy appearance when polished.
