Pharmacology
Ethyl butylacetylaminopropionate 12.5% w/w (IR 3535) is the active ingredient. It is a technical grade synthetic biochemical made by an integrated process. It is a substituted ß-amino acid, structurally similar to naturally occurring ß-alanine. No harmful effects to humans or the environment are expected from this use of 3-[N-Butyl-N-acetyl] aminopropionic acid, ethyl ester.
Biochemical Description
In 1997, EPA-OPP's Biochemical Classification Committee classified IR 3535 as a biochemical. It gave several reasons. IR 3535 is functionally identical to naturally occurring beta alanine, because both repel insects. The basic molecular structure is identical, and the end groups are not likely to contribute to toxicity. It also controls the target insects through a non-toxic mode of action.
Assessing Risks to Human Health
IR 3535 has been used as an insect repellent in Europe for 30 years with no substantial adverse effects. Toxicity tests show it is not harmful when ingested, inhaled, or used on skin. Eye irritation could occur if the chemical gets into a person's eyes. Any allergic reactions must be reported.
Assessing Risks to the Environment
The active ingredient is used only in products applied to human skin, so no risks to the environment are expected.
