Abstract

An insect-repelling agent contains N,N-diethyl-m-toluamide (DEET) based on alcohol solutions as the active ingredient (repellent), and further contains an adjuvant that extends the period of effectiveness of DEET following application to human skin. It is proposed that the sole adjuvant is glycerol in an amount of more than 10 percent by weight of the insect-repelling.
