Picaridin
Picaridin
Picaridin, also known as Icaridin, is a synthetic compound used as an insect repellent. It is a colorless and nearly odorless liquid that is effective against a wide range of insects, including mosquitoes, ticks, and flies. Picaridin is considered a safer alternative to DEET, another common insect repellent, due to its lower toxicity and skin irritation potential.
Chemical Properties[edit | edit source]
Picaridin is a member of the piperidine family of chemicals. Its chemical name is 1-piperidinecarboxylic acid, 2-(2-hydroxyethyl)-, 1-methylpropyl ester. The molecular formula is C12H23NO3, and it has a molecular weight of 229.32 g/mol.
Mechanism of Action[edit | edit source]
Picaridin works by interfering with the olfactory senses of insects, making it difficult for them to detect humans and other animals as potential hosts. This repellent effect reduces the likelihood of insect bites and the transmission of vector-borne diseases.
Efficacy[edit | edit source]
Studies have shown that Picaridin is as effective as DEET in repelling mosquitoes and other biting insects. It provides long-lasting protection, typically up to 8-10 hours, depending on the concentration and environmental conditions.
Safety and Toxicity[edit | edit source]
Picaridin is considered to have a favorable safety profile. It is less irritating to the skin and eyes compared to DEET and has a lower potential for causing allergic reactions. Picaridin is also less likely to damage synthetic materials, such as plastics and fabrics.
Usage[edit | edit source]
Picaridin is available in various formulations, including sprays, lotions, and wipes. It is commonly used in concentrations ranging from 5% to 20%, with higher concentrations providing longer-lasting protection.
Regulatory Status[edit | edit source]
Picaridin is approved for use as an insect repellent by regulatory agencies such as the Environmental Protection Agency (EPA) in the United States and the European Chemicals Agency (ECHA) in the European Union.
Environmental Impact[edit | edit source]
Picaridin is considered to have a low environmental impact. It is biodegradable and does not accumulate in the environment. Its use is not associated with significant ecological risks.
