wax

Chemistry

Any of various solid or semisolid substances. There are two main types. Mineral waxes are mixtures of hydrocarbons with high molecular weights. Paraffin wax, obtained from petroleum, is an example. Waxes secreted by plants or animals are mainly esters of fatty acids and usually have a protective function.

Chemical Engineering

A solid or semi-solid substance with may be either a monoester of fatty acids or a mixture of hydrocarbons of high molecular weight. As a monoester, such as beeswax, the acid and alcohol proportions both have long saturated carbon chains:
$C_{25 - 27} H_{51 - 55} C O O C_{30 - 32} H_{61 - 65}$

Waxes are used to make polishes, cosmetics, pharmaceutical preparations, ointments, and candles. In nature, waxes coat leaves and stems in plants that grow in arid conditions and have a protective effect.
