Acute Toxicity: Oral and dermal toxicity low to moderate, ingestion irritates gastrointestinal tract
Skin Sensitization: May provoke irritation or rashes, especially after repeated or prolonged exposure
Eye Effects: Redness and watering, possible corneal injury with high concentrations
Chronic Exposure: Prolonged contact may dry or crack skin; avoid repeated exposure
Inhalation Risks: Vapors, though low in volatility, may irritate respiratory passages with inadequate ventilation
Carcinogenicity: No evidence classifies this substance as carcinogen; available studies limited
Aquatic Toxicity: Demonstrated harmful effects for aquatic organisms at high concentrations, disrupts microorganism balance in water
Persistence and Degradability: Not readily biodegradable, potential for long-term environmental persistence
Bioaccumulation Potential: Low due to ionic structure, concern at high and repeated releases
Mobility in Soil: Tends to persist where released; high water solubility increases potential for groundwater impacts
Other Adverse Effects: No data on ozone depletion or photochemical impacts; prudent management reduces broader risks
