Soft paraffin waxes are used as consistency regulators in creams, lotions, soft lip care products and other formulations requiring a paraffin component with elevated softness combined with a low melting and solidification point. It is sold with various melt points, typically between 43-60 °C (other melting points are available on request) and has a boiling point above 370 °C. After using solvents to separate the wax (product wax or press wax) from the oil (foots oil), it can be further refined to remove the colour and odour and then blended to achieve certain melting points. method, highlighting the critical issues related to the determination and suggesting a suitable way of improving the melting point of paraffin wax to suit a latent heat and thermal energy storage application. Crude oils differ widely in wax content. Is paraffin wax bad for you? Synthetic paraffin wax was introduced commercially after World War II as one of the products obtained in the Fischer–Tropsch reaction, which converts coal gas to hydrocarbons. Paraffin wax is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C (115 and 154 °F),[8] and a density of around 900 kg/m3.

The melting point ranges from 47 to 65°C (Lewis 2002). This mixture is filtered into two streams: solid (wax plus some solvent) and liquid (oil and solvent). The wax may finally be blended together to give certain desired properties such as melt point and penetration. Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal or shale oil that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms. Melting points for paraffin waxes have a range of 125 °F to 165 °F and may be classified into three general grades: Soft and pliable waxes, like beeswax, may be preferred for such sculpture, but "investment casting waxes," often paraffin-based, are expressly formulated for the purpose. This wax feels harder than low melting point wax, but it keeps its shape better. Paraffin wax, colorless or white, somewhat translucent, hard wax composed of saturated hydrocarbons ,with a melting point in the range of about 48° to 66°C (120° to 150°F).
