Researchers from the U.S. Department of Agriculture compounds derived from coconut oil are better than diethyltoluamide (DEET) at preventing disease transmission and discomfort associated with insect bites. DEET has been considered the gold standard in insect repellents, the most effective and long-lasting available commercially, for more than 60 years.
However, increasing regulations and growing public health concerns about synthetic repellents and insecticides like DEET have sparked interest in developing plant-based repellents that are more effective and longer lasting. The coconut oil-derived free fatty acid mixture, lauric acid, capric acid and caprylic acid as well as their corresponding methyl esters, provides strong repellency against blood-sucking insects.
