Dr. Oscar Novick. 1 doctor shared a insight. Ear wax in the ear canal is a mixture of secretions from oil and sweat glands in the canal's skin. Shedded skin cells are also a major ingredient of ear wax. There are two genetically determined types of ear wax: the wet type and the dry type. While Asians and Native Americans are more likely to have the dry type (crumbly, flaky), Africans and Europeans are more likely to have the wet type (sticky, moist).
