Skin Corrosion/Irritation: Causes redness, irritation, possible blistering with prolonged contact
Eye Damage/Irritation: Can cause pain, watering, and conjunctival irritation
Respiratory Effects: Exposure to dust or vapor may cause respiratory tract irritation
Chronic Effects: Long-term data lacking, repeated exposure could increase sensitivity
Carcinogenicity: No evidence for N-butylimidazolium chloride being carcinogenic
Mutagenicity: No data for genetic toxicity, structurally related ionic liquids suggest low potential
Other Data: Persons with pre-existing skin or respiratory disorders could see aggravated symptoms
Aquatic Toxicity: Harmful to aquatic organisms based on ionic liquid research, may cause long-term adverse impacts
Persistence/Degradability: Limited biodegradation in soil and water, expected to persist in environment
Bioaccumulation Potential: Moderate due to ionic structure, not likely to accumulate in animal tissue
Soil Mobility: High solubility in water leads to possible migration in soil and groundwater
