Abstract
An insect repellent is disclosed which comprises, as essential ingredients, N,N-diethyltoluamide as a repellent component, and an aromatic proton donor in which the aromatic rings are substituted directly by hydroxyl and/or carboxyl groups. This repellent composition has a longer lasting effect due to increased resistance to absorption through the skin.
