What is wax?

Wax is a thin coating found in many fruits, vegetables, and leaves of plants. Animals too produce wax. Synthetic waxes are also available. Minerals and petroleum too contain wax. Beeswax is used to make candles, cosmetics, crayons and artificial flowers. Most of the commercial wax in use today is petroleum wax. Synthetic wax is made by combining hydrogen, carbon, oxygen, and sometimes chlorine.
