Ethyl Butylacetylaminopropionate, BAAPE

Product Overview

Ethyl butylacetylaminopropionate (common names: BAAPE, IR3535; CAS 52304-36-6) is a colourless, low-toxicity liquid insect-repellent active ingredient widely used as an alternative to DEET and Icaridin. It delivers broad-spectrum protection vs mosquitoes, flies, ticks and other biting arthropods, with good thermal stability and sweat resistance — making it suitable for personal care repellents (sprays, lotions, wipes), treated textiles and consumer aerosol formats.

Ethyl butylacetylaminopropionate (BAAPE), also known as butyl acetylaminopropionic acid ethyl ester, BAAPE, IR3535, Imogen, is a plasticizer and a broad-spectrum, high-efficiency, low toxicity insect repellent.
