IR3535® (Ethyl butylacetylaminopropionate), developed by Merck, is a cutting-edge, highly effective insect repellent, specifically designed to provide long-lasting protection against mosquitoes, ticks, and other insects. What sets IR3535® apart is its safety profile—approved by the U.S. Environmental Protection Agency (EPA) and classified by the World Health Organization (WHO) as “unlikely to present acute hazard in normal use.” Remarkably, IR3535® is the first insect repellent active ingredient without any age restrictions, making it safe for infants, children, and pregnant women alike. This is due to its inspiration from the naturally occurring amino acid ß-alanine, which ensures high tolerability and safety.

In terms of performance, IR3535® has been shown to provide up to 8 hours of protection in a variety of formulations, including lotions, sprays, and aerosols. Field and laboratory studies have demonstrated its efficacy against insects that carry diseases such as Zika virus, dengue fever, and malaria. In fact, IR3535® has been proven to perform on par with DEET at higher concentrations, but without the skin irritation often associated with traditional repellents. Additionally, IR3535® is non-toxic to aquatic life and does not accumulate in the environment, making it an environmentally conscious choice.

By incorporating IR3535® into our “Baby Insect Repellent,” we offer a powerful, safe, and eco-friendly solution that ensures comprehensive protection for the most sensitive skin.
