| Message: | Wax is class of compounds that are melt-able solids near environment temperatures. Wax includes higher alkane and lipids, typically with melting point above about 50 C, melting to give low viscosity liquids. Waxes are insoluble in water but soluble in organic, non-polar solvents. Natural waxes of different types are produced by plants and animals and occur in petroleum.
Wax is a general term used to refer to the mixture of long-chain lipids forming a protective coating on plant leaves and fruits but also in animals algae, fungi and bacteria. Some waxes are of mineral origin. The various materials named waxes do not form a chemically homogeneous group. All waxes are water-resistant materials made up of various substances including hydrocarbons (normal or branched alkanes and alkanes).
More commonly, waxes are esters of an alcohol other than glycerol and a long chain acid (wax esters). Wax esters are saponified by hot alkaline solutions and give a fatty acid and an alcohol.
