Beeswax is a natural wax produced in the bee hive of honey bees of the genus Apis. The wax is formed by eight wax-producing glands in the abdominal segments 4 through 7 of worker bees. The workers collect it and use it for structural material in the hive. Chemically, beeswax consists of mainly esters of fatty acids and various long-chain alcohols. Beeswax may also be used as a food additive E901, in small quantities acting as a glazing agent, which serves to prevent water loss, or used to provide surface protection for some fruits. Soft gelatin capsules and tablet coatings may also use E901. Beeswax is also a common ingredient of natural chewing gum also the use of beeswax in skin care and cosmetics has been increasing.
