wax

Waxes are a diverse class of organic compounds that are lipophilic solids that are malleable near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in nonpolar organic solvents such as hexane, benzene and chloroform. Natural waxes of various types are produced by plants and animals and occur in petroleum.
