• 体外研究: 苯扎氯铵(0.0001％-0.5％)导致细胞中的剂量依赖性细胞毒性。苯扎氯铵还显示出对人角质形成细胞的细胞毒性,50μ％的存活率损失为4μM。苯扎氯铵在NHEK和NB1RGB细胞培养物中显示出不同的结果,并且ED50分别为3.9和62μM。临床使用的浓度(0.01％苯扎氯铵)显着降低细胞活力,只有14％-19％的鼻上皮细胞在治疗中存活[1]。
• 体内研究: 在光学和电子显微镜检查后,苯扎氯铵(0.02％)在猴的鼻上皮中没有引起异常。在4-5周龄SD大鼠中,0.01％和0.1％苯扎氯铵诱导鼻呼吸道上皮厚度随时间的增加[1]。

Toxicity to Animals Special Remarks onMay affect genetic material (mutagenic). Chronic Effects on HumansMay cause adverse reproductive effects based on animal test data. Benzalkonium Chloride is an active ingredient in vaginal spermacides. When applied in the vagina of pregnant rats at much higher doses than those used in spermacides, it caused increased resorptions leading to fetal death, and reduced litter size and weight. No adverse reproductive effects have been reported after oral treatment of rats and guinea pigs and dermal administration to rats. Special Remarks on otherAcute Potential Health Effects: Toxic Effects on HumansSkin: Causes severe skin irritation and burns. Eyes: Causes sever eye irritation and burns. Ingestion: Harmful if swallowed. May cause severe and permanent damage to the digestive tract. Causes gastrointestinal (digestive) tract burns. May affect behavior (central nervous system depression, depression) and metabolism. May produce burning pains in the mouth, throat, and abdomen, profuse salivation, muscle weakness. May also affect the respiratory system and cardiovascular system, liver and kidneys. Inhalation: May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath, and delayed lung edema. Causes chemical burns to the respiratory tract. Causes irritation of the mucous membranes. Chronic Potential Health Effects: May affect material (mutagenic) and may cause adverse reproductive effects. Prolonged or repeated skin contact may cause dermatitis. Repeated or prolonged exposure may cause allergic reactions in sensitive individuals. May cause cyanosis of the skin and lips caused by lack of oxygen. Section 12. Ecological Information Not available. Ecotoxicity Not available.
