Detailed explanation-1: -The lubrication provided by cerumen prevents desiccation of the skin within the ear canal. The lubricative properties arise from the high lipid content of the sebum produced by the sebaceous glands. In wet-type cerumen, these lipids include cholesterol, squalene, and many long-chain fatty acids and alcohols.
Detailed explanation-2: -Wet earwax is 50% lipids while dry only has 20% lipids. Earwax is cleared from the canal by movement of the jaw when chewing and head movement. Usually it will migrate towards the outer ear over time. Earwax provides lubrication of the ear canal to keep it from completely drying out.
Detailed explanation-3: -Another type of lipid is wax. Waxes are esters made of long-chain alcohol and a fatty acid. They provide protection, especially to plants in which wax covers the leaves of plants.
