Your ear canal produces a waxy oil called cerumen, which is more commonly known as earwax. This wax protects the ear from dust, foreign particles, and microorganisms. It also protects ear canal skin from irritation due to water. Wax buildup is a common reason for temporary hearing loss.
Considering this, what is a wax made out of?
For most of recorded history candles were tallow (a by-product of beef-fat rendering) and beeswax until the mid 1800s at which point they were made mainly from spermaceti (spurring larger demand for whale oil), and stearin (initially manufactured from animal fats but now produced almost exclusively from palm waxes).
What makes wax in your ears?
The skin in the outer ear canal has special glands that produce earwax. The fancy name for this waxy stuff is cerumen (say: suh-ROO-mun). After the wax is produced, it slowly makes its way through the outer ear canal to the opening of the ear. Then it either falls out or is removed when you wash.
