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.
Purpose. Ear wax is produced in the outer ear canal. The main purpose of wax is to lubricate the very thin layer of skin in the canal, to keep the canal sterile, and to repel bugs from entering our ear. Great purposes however, too much ear wax can cause pain, temporary loss of hearing, and temporary dizziness.urpose. Ear wax is produced in the outer ear canal.
