Определение

Drometrizole is a member of triazoles.

Оценка токсичности

The mutagenicity study of drometrizole was performed using Salmonella typhimurium strains TA1538 and TA98 with metabolic activation in the Ames’ test. Spot test (10 and 100 mg drometrizole/plate) and top agar method (50 and 100 mg drometrizole/plate) were conducted. The results showed that drometrizole was not mutagenic.Mice and rats were administered 5.0 or 10.0 g/kg of drometrizole in sunflower oil by stomach tube intubation. After body weight and behaviour were monitored for 3 weeks, acute toxicity of drometrizole was evaluated to be low. The oral lethal dose (LD50) of drometrizole in mice was reported to be 6.5 g/kg and > 5.0g/kg. Oral toxicity was evaluated in rats for nail care cosmetics containing 1%, 0.3% and 0.03% of drometrizole. The LD50 of products containing 1% of drometrizole was > 15.0 g/kg. The LD50 of products containing 0.3% and 0.03% drometrizole was > 5.0 g/kg. No acute toxicity was observed in these treatments.
