Ear Wax

Although Bertie Bott’s obviously thought that ear wax would make a very tasty jelly bean flavor, mother nature had quite a different purpose in mind for this helpful substance…
What is Ear Wax?
The skin covering the outer part of the ear canal contains special glands that produce ear wax, a sticky, waxy substance also known as cerumen which is different from candle wax (paraffin). Our skin contains many tiny glands whose purpose is to secrete a variety of substances. Sebaceous glands, for example, secrete sebum (skin oil). Sweat is also produced by microscopic glands. Cerumen glands are found only in the skin of the ear canals. The purpose of this natural wax is to protect the ear from bacteria, foreign substances such as dust and insects as well as to serve as a temporary water repellent.
Cerumen may vary in form and appearance. It may be almost liquid, or firm and solid. The color of ear wax can also vary depending upon its composition. The primary component of ear wax is keratin (derived from dead skin). Glandular secretions, sweat, oil and bacteria from the surface of the ear canal may also be present in the ear wax you see on the end of your Q-Tip.
