Acute Toxicity: Data limited; estimated LD50 oral (rat): >2000 mg/kg
Skin Irritation: May cause redness, dryness, or cracking with repeated exposure
Eye Irritation: May cause stinging, redness, watering
Respiratory Effects: Inhalation might cause coughing, sore throat, or headache
Sensitization: Potential for allergic skin reaction
Chronic Effects: Endocrine activity means repeated exposure could impact reproductive hormones or fertility
Mutagenicity / Carcinogenicity: No animal carcinogenicity reported; mutagenicity unassessed
Other Information: Not intended for human consumption. Use only in controlled laboratory environments
Ecotoxicity: Not tested directly, likely toxic to aquatic life due to steroid physiology effects
Biodegradability: Expected to persist in environment, not readily biodegradable
Bioaccumulation: Potential for bioaccumulation in wildlife because of lipophilicity
Mobility: Insoluble in water, expected low mobility in soil
Aquatic Toxicity: Estimated EC50 (daphnia, fish): low concentrations may disrupt hormonal balance or reproduction
