Although there are many other kinds of insect waxes, only two are of economic importance namely, shellac wax and Chinese insect wax. Shellac wax is derived from the lac insect, a parasite that feeds on the sap of the lac tree indigenous to India. The commercial wax is not ordinarily the native Indian lac wax, but is a by-product recovered from the dewaxing of shellac spar varnishes. Lac wax melts at 72-80°C, whereas commercial shellac wax melts at 80-84.5°C. Its high melting point and dielectric properties favor its use in the electrical industry for insulation. Chinese insect wax is the product of the scale insect. 

Some other members of the Coccoidea produce waxy secretions that are collected, concentrated, and used for a variety of purposes. These waxes have several names, including Chinese insect wax and Japanese insect wax. Both lac and insect wax are produced largely in China, India, and southeast Asia.

Chinese wax is a white to yellowish-white, gelatinous, crystalline, water-insoluble substance obtained from the secretion of the scaled insect Coccus ceriferus, common in China and India. Chinese wax is used chiefly in the manufacture of polishes, sizes, and candles and is traditionally employed in Chinese medicine. It is basically made up of ceryl cerotate (esacosanoyl esacosanoate) and esacosanol [78,79].
