Hazardous Decomposition: Carbon monoxide, carbon dioxide, other toxic fumes with decomposition
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Effects: Eye and skin irritation, respiratory irritation
Chronic Effects: Data is limited; repeated exposure may increase sensitivity
LD50/LC50: No high-quality animal test data publicly available, toxicity is considered low but protective measures are necessary until more safety data exists
Symptoms of Overexposure: Redness, itching, coughing, headache, possible nausea
Carcinogenicity: Not classified by IARC, NTP, or OSHA as a carcinogen
Reproductive/Developmental Effects: Not listed, insufficient data for classification
Aquatic Toxicity: Limited data available; phenolic compounds generally can be harmful to aquatic organisms at higher concentrations
Persistence and Degradability: Likely to undergo slow biodegradation in the environment
Bioaccumulation: Potential for bioaccumulation due to lipid solubility (log Pow above 4)
Mobility in Soil: Expected to have low mobility, can adsorb onto soil particles
Other Adverse Effects: Avoid uncontrolled environmental release to prevent impact on water bodies and soil organisms
