Ethyl aminobenzoate, also known as benzocaine, is a local anesthetic used to numb the skin or mucous membranes. Some synonyms for ethyl aminobenzoate are benzoyl ethylamine, ethyl 4-aminobenzoate, and N-ethyl-4-aminobenzoate. It is often used in cosmetics, such as lip balms and topical creams, as well as in dental procedures. Benzocaine works by blocking nerve signals and preventing pain impulses from reaching the brain. It is an effective and widely used anesthetic, but should be used with caution as it can cause allergic reactions in some individuals. Always follow proper dosage and usage guidelines when using benzocaine or any other medication.
