The chemicals have to be in contact with each other in order for any type of chemical reaction to take place. One of the most common examples of a chemical reaction is the rusting of a fence. The combining of the metal and the oxygen causes bonds to break and new ones to be created, which results in the creation of iron oxide or rust.
The ear canal cleans itself with a waxy secretion called cerumen. Cerumen is resistant to water, sticky (to trap dust) and migrates out of the ear canal to self-clean the ear. Sometimes, the wax builds up and causes symptoms, including mild deafness and a sensation of fullness inside the ear.
is inherited. The wet wax is common in western Europe and contains about 50% fat. Dry wax is common in Asia and contains about 20% wax. How does earwax get out? Your jaw joint forms one third of the ear canal. As you chew or talk, the joint moves the skin of the canal, slowly pushing the wax out and taking trapped debris with it. This wax falls out at random. So it is natural and expected to have flakes of ear wax drop out of your ear canal. Why does wax build up? Earwax is necessary and good. It can build up though blocking the ear canal and causing hearing loss, infection or pain.
