10,172,775 B2 (Jerry Steven Johnson); Sunsect, Inc., Tallahassee, FL, has patented a combination sunscreen and insect repellant composition comprising diethyl toluamide (or N, N-diethyl-3-methylbenzamide or DEET); and two or more sunscreen components, each of said two or more sunscreen components that are comprised of 1-(4-methoxyphenyl)-3-(4-tert-butylphenyl)propane-1,3-dione and (RS)-2-ethylhexyl (2E)-3-(4-methoxyphenyl) prop-2-enoate.
On a chemical by chemical basis, false GARD classifications were obtained for thioglycerol, benzoyl peroxide, penicillin G, hexyl salicylate (false negatives, HP category 1-4), hydrocortisone, methyl salicylate, triethanolamine, propyl paraben (false positives, HP category 5) and tocopherol, diethyl phthalate, diethyl toluamide and Tween 80 (false positives, HP category 6).
Furthermore, diethyl phthalate and diethyl toluamide are both frequently classified as positives in cell-based assays (Ashikaga et al., 2010; Piroird et al., 2015), while Tween 80 is consistently classified as a sensitizer in numerous assays (Emter et al., 2013; Piroird et al., 2015; Ramirez et al., 2014).
The only insect repellents that are recommended are those containing diethyl toluamide (DEET).
