| KNOWN ABSORPTION STUDIES OF DEET To date only two studies have been conducted regarding the skin absorption rate of DEET: The first was a series of studies conducted by the industry in Belgium in the mid‑1980's. In all, eight human subjects were observed. It is from these studies that the generally accepted 4% to 8% absorption rate, which is often used by the medical community, was obtained. Due to the complexity of the study not all DEET applied could be accounted for, but based on a long history of animal studies conducted by manufacturers during the EPA approval process, it was concluded that none of the DEET remains in the human body after 72 hours. The second study was conducted in California in 1995 where DEET was observed as part of a blend with R‑11, a repellent similar to R‑326, and MGK‑264. In this study four human subjects were observed. The conclusion of the study was that when combined with these two larger molecules, the absorption rate of DEET was reduced to a range of 3% to 6%. This represented a reduction in absorption of 25%. This blend is used in the Sawyer composites. The American Academy of Pediatrics published information on using DEET with infants an excerpt follows: “Pediatricians and other pediatric health care providers should help their patients understand the risk of WNV infection and methods to prevent infection. Children and pregnant women should be encouraged to apply insect repellent to skin and clothing when exposed to mosquitoes. The most effective repellents contain DEET, which can be used by children and pregnant women without adverse effects.”
