业已证明,有效驱虫剂N,N-二乙基-间甲苯酰胺(下简称DETA)毒性很低,以10～100%的浓度长期任意涂于人体皮肤未发现有较明显副反应。作者用体外扩散池法测定10余种制剂释药百分比并与以DETA作溶媒(基质)进行比较。
It has been proved that the effective insect repellent N, N-diethyl-m-toluamide (hereinafter referred to as DETA) is very low toxicity and any long-term random application to human skin at a concentration of 10-100% shows no obvious side reaction. The authors used an in vitro diffusion method to determine the percentage release of more than 10 formulations and compared them to DETA as a vehicle (matrix).
