살균소독제, 라미아-킬(benzalkonium chloride(20%), citric acid(20%))에 대하여 랫드와 토끼를 이용하여 급성경구독 성과 피부 자극성 평가를 각각 수행하였다. 랫드에 라미아-킬 2,000 mg/kg 농도를 최고농도로 하여 단회 투여 후, 14일간 관찰한 결과, 사망, 이상증상 및 체 중변화 등은 관찰되지 않아, 라미아-킬의 $LD_{50}$은 2,000 mg/kg 이상으로 추정되었다. 토끼의 등 부위의 털을 제거하고 찰과부위와 비찰과 부위에 여러 농도로 라미아-킬을 도포 한 후, 피부 자극성을 확인한 결과, 라미아-킬의 l차 자극 지수가 0.50으로 비자극성 물질로 분류되었다. 따라서, 본 연구를 통하여, 라미아-킬은 급성경구독성 시 안전한 물질이며, 피부 자극성을 야기하지 않는 물질로 평가되었다.
This test was performed to evaluate the acute oral toxicity and skin irritation of Lamia-Kill$^{(R)}$, disinfectant, containing 20% benzalkonium chloride and 10% citric acid. In acute oral toxicity, Lamia-Kill$^{(R)}$ was orally administered at dose levels of 2,000, 1,000, 500, 250 and 0 mg/kg body weight. After single oral administration to both sexes of SD rats, the rats were observed for 14 days. In primary skin irritation test, New Zealand white rabbits were dermally treated with Lamia-Kill$^{(R)}$ for 24 hr and observed for 3 days. All rats treated with Lamia-Kill$^{(R)}$ were induced no toxic signs in mortalities, clinical findings, body weights and gross findings. Also, the disinfectant did not induce any adverse reactions such as erythema and edema on intact skin sites for the most part rabbits, but on abraded skin sites, some rabbits showed very slight erythema on 24 hr after topical application. With the results of this study, Lamia-Kill$^{(R)}$ have no effect on acute toxicity and side effect in SD rats and was classified as a practically non-irritating material based on the score 0.50 of primary irritation index.
