Epicuticular waxes of plants are important in protecting plants from a variety of several environmental factors, such as reducing evaporation of water from the surface, which prevents dehydration, and controlling important physiological properties. The waxes may consist of long chain alkanes, free carboxylic fatty acids, aldehydes, alcohols, and esters, but the composition varies between species, organ, age, and the environmental factors that are present in the location of the plants. The diversity of the chemical compositions, microcrystalline structures, and relative amounts of waxes are mostly associated with plant protection against certain environmental stresses that may be caused by insects or even drought. The constituents of the waxes are usually long chained, most often ranging from 16 to 34 carbons in length. Analysis of the free acids in cuticular waxes is important because the reactions that generate them define a central control point in the overall metabolism of the cuticular waxes. The epicuticular waxes also play a role in the industry sector, being used in candles, cosmetics, polishing agents, and medicinals.
