The primary component of ear wax is dead skin.

Ear wax is formed from wax glands in the outer ear canal as well as from sweat, oil, and a protein called keratin that is derived from dead skin. There are two main types of ear wax: wet wax and dry wax. Dry wax is prevalent in Asia, while wet wax is more common in Europe and the western world. Ear wax is a tricky thing - if you have too much of it, it is hard to hear and you have a higher risk of infection, but if you have too little, you also increase your risk of infection!
