What Is Ear Wax Made Out Of

Ear wax is a yellowy-orange, waxy substance that is found in the ear canal of humans and other mammals. The medical term for ear wax is cerumen and excess, or compacted cerumen, can cause hearing difficulties. Ear wax is secreted by the ear to protect the skin of the ear canal and assist with cleaning and lubrication. Ear wax is able to provide some protection from bacteria, fungi, insects and water entering the inner ear. When the ear wax dries it falls out of the ear taking with it any trapped dust or debris.

What is ear wax made out of?
Ear wax is made in the outer ear canal. This is the section of the ear between the outside, fleshy part of the ear and the middle ear. Specialized glands in the wall of the outer ear called the sebaceous glands and apocrine sweat glands secrete the substance that we know as ear wax. Ear wax is mostly comprised of shed layers of skin with over 60% of ear wax being made up of keratin. Keratin is the fibrous protein that the outer layer of human skin in made up of. Other substances in ear wax include cholesterol (6-9%), saturated and unsaturated long-chain fatty acids, squalene and alcohols.
