TriclosanCAS#3380-34-5
High Stability: Stable at high temperatures (up to 290°C) and resistant to UV degradation, ensuring long shelf life.
Low Volatility: Minimal volatility with a faint floral odor, making it suitable for long-term applications.
Versatile Solubility: Soluble in a range of solvents, including alcohols and alkali solutions, enhancing formulation flexibility.
Low Toxicity: Exhibits low toxicity, with a high safety profile for use in various products.
Triclosan properties: 1. Appearance: A white crystalline powder with a mild floral or phenolic odor. 2. Solubility: Slightly soluble in water, moderately soluble in dilute alkali, and soluble in organic solvents like ethanol and acetone. It can dissolve in surfactants to form a transparent concentrated liquid. 3. Stability: Highly stable during storage; it doesn't decompose quickly below 280-290°C. Even after heating at 200°C for 14 hours, only 2% of the active substance decomposes. Long-term exposure to UV light results in minimal decomposition, and its solution remains stable in both acids and alkalis. 4. Volatility: Very low volatility with a faint floral scent.
