Icaridin

Icaridin, also known as Picaridin or KBR 3023, is a synthetic compound widely used as an insect repellent. It is an effective repellent against a variety of biting insects, including mosquitoes, ticks, flies, and gnats. Icaridin was developed in the 1980s by Bayer AG, and its efficacy and safety have been studied extensively.

The effectiveness of icaridin is comparable to DEET, another common insect repellent, and it is often considered a more pleasant alternative due to its lack of odor and greasy feel. It works by interfering with the ability of insects to detect hosts, such as humans, by blocking their olfactory receptors. Icaridin is available in various concentrations, typically ranging from 10% to 20%, and is found in lotions, sprays, and wipes.

Icaridin is generally considered safe for topical use. Regulatory bodies in various countries, including the World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA), have approved its use. While rare, some individuals may experience mild skin irritation. It is recommended to follow product instructions for application and to avoid contact with eyes and mucous membranes. Icaridin is also recognized for its low environmental impact, as it degrades relatively quickly in the environment.
