Chronic Effects: No evidence of carcinogenicity, mutagenicity, or reproductive toxicity in humans
Medical Conditions Aggravated by Exposure: Pre-existing skin disorders may become aggravated by prolonged contact
Aquatic Toxicity: Low toxicity to aquatic organisms (EC50 >100 mg/L for daphnia and fish)
Persistence and Degradability: Readily biodegradable in the environment by natural microorganisms
Bioaccumulation Potential: Low bioaccumulation due to high water solubility and rapid metabolism
