Conditions to Avoid: Strong heat, contact with strong acids or oxidizers, static discharge
Incompatibility: Alkalis, oxides, certain metals in fine powder form
Likely Routes of Exposure: Skin contact, eye contact, inhalation, accidental ingestion
Acute Toxicity: No data for oral, dermal, or inhalation LD50 in humans, animal studies show moderate toxicity at very high doses
Irritation: Can irritate skin and eyes
Chronic Effects: Long-term effects not well studied, repeated exposure may irritate mucous membranes
Sensitization: Not reported under current data
Carcinogenicity: No evidence from studies or regulatory listings
Reproductive Toxicity: No data available
Other Effects: Not known to cause allergic reactions or systemic toxicity under regular use
Aquatic Toxicity: Moderately toxic to aquatic life if released in large amounts, can persist and accumulate
Persistence and Degradability: Poorly biodegradable under standard conditions
Mobility in Soil: Moderate due to ionic nature, some risk of leaching
Bioaccumulation: Not expected to bioaccumulate substantially, but chronic impact not fully studied
Other Adverse Effects: Prevent entry to surface waters or drains, long environmental half-life possible
