PABA has been most often utilized by humans as a component in sunscreens, successfully protecting the skin from harmful ultraviolet radiation. However, the frequent occurrence of PABA-related skin irritations has led many companies to introduce suntan oils and lotions that are PABA-free. Many people may also be familiar with ethyl-PABA, more commonly known as benzocaine, the key ingredient in many pain and itch relief ointments. In the chemical industry, PABA is utilized as an intermediate in the production of esters, folic acid, and other organic compounds.
