DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

Pest Management Science, EarlyView.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.
