| Hazard Information | Back Directory | [Description]
Ethyl butylacetylaminopropionate (IR3535) is effective against several insects and is considered an alternative repellent to DEET and Icaridin, thanks to its very low toxicity and equal efficacy. Officially considered safe and effective for use in children over 2 months of age and pregnant and breastfeeding women by the World Health Organization, this repellent has been used in Europe for over 30 years, and its use has been increasing worldwide[1]. | [Physical properties]
Ethyl butylacetylaminopropionate is a natural product found in Averrhoa bilimbi with data available. | [History]
Ethyl butylacetylaminopropionate is a synthetic molecule derived from a natural amino acid, b-alanine, and its alternative chemical formula name is beta-alanine, n-acetyl-N-butyl-ethyl ester. It is known as IR3535 or EBAAP in the literature. This molecule was developed in the early 1970s using targeted molecular design following functional structure guidelines similar to those reported by Boeckh.1 In his study, repellency of a chemical was correlated with a structural pattern consisting of an amide group linked by a lipophilic chain to an sp3 (i.e., an oxygen atom without a double bond) hybridized oxygen within a group such as hydroxyl or ester. IR3535 repellent (hereafter referred to as IR3535) is currently used in over 150 consumer products world-wide. Despite its commercial history of more than 10 years world-wide and 25 years in European countries, IR3535 has been introduced as a product in the U.S. only recently (1999). | [Uses]
Insect repellent. | [Definition]
ChEBI: Ethyl 3-(N-butylacetamido)propionate is a tertiary carboxamide, a member of acetamides and an ethyl ester. | [Safety]
Ethyl butylacetylaminopropionate (IR3535) is a transparent, colourless, odourless liquid mixture proven safe, as demonstrated by acute toxicity, local tolerability, phototoxicity and repeated-dose toxicity assays. Further, IR3535 is non-genotoxic and has thus been considered a safe insect-repellent ingredient by the US Environmental Protection Agency since 1999. Moreover, this compound is classified as a hypoallergenic substance based on skin irritation tests. IR3535 is mainly used as a mosquito/mite repellent sprayed on the body or clothing during outdoor activities. This compound does not have a sticky texture or an offensive odour, which makes it uniquely well-suited for topical use. Further, the effects of IR3535-based insect repellents can last up to 4 h with a single spray. IR3535 is yet to be linked to any toxic effects and is thus considered safe even in cases of exposure via ingestion, inhalation or skin penetration[2].
