Benzoyl peroxide is also known as dibenzoyl peroxide, benzoyl peroxide, Acetoxyl, Acnegel, Benoxyl, Lucidol, Nericur, Xerac, BP5. White orthorhombic crystal or crystalline powder. Slight odor of benzaldehyde. A bitter taste. The relative molecular mass is 242.23. The relative density is 1.3440 (25°C). Melting point 103 ~ 106 ℃ (decomposition and explosion). Refractive index 1.545. Flash point 125 ℃. Strong oxidant, flammable and explosive. Very slightly soluble in water, slightly soluble in methanol, isopropanol, soluble in ethyl alcohol (1.2g/100g), acetone (18.5g/100g), chloroform (26.8g/100g), ethyl acetate (14.4g/ 100g), benzene (18.6g/100g), ether (8.6g/100g). The half-life in solution is 2.1h (85°C), 10h (72°C). Slowly decomposes in alkaline solution. Stable at room temperature, easy to explode due to friction, impact or heating in dry state. Adding sulfuric acid can burn. Because it is a strong oxidant, it can cause inflammation of the skin and mucous membranes. Mice orally LD503949mg/kg.
