Boric acid is a white powder crystal or a scaly glossy crystal with a tri-oblique axis. It has a smooth feel and no odor. Soluble in water, alcohol, glycerin, ethers and essential oils. Odorless. The taste is slightly sour and bitter and then sweet. Slippery feeling on contact with skin. No change in exposed air. Can be volatile with water vapor. When heated to 100-105 ℃, it loses a molecule of water to form metaBoric acid, and when heated for a long time at 104-160 ℃, it transforms into pyroBoric acid, and at higher temperature, it forms anhydrous. The pH of 0.1mol/L aqueous solution is 5.1. 1g can be dissolved in 18mL cold water, 4mL boiling water, 18mL cold ethanol, 6mL boiling ethanol and 4mL glycerol. The solubility in water can be increased with the addition of hydrochloric acid, citric acid and tartaric acid. The relative density is 1.4347. Melting point 184 ° C (decomposition). Boiling point 300 ℃. The median lethal dose (rat, oral) is 5.14g/kg. irritating. Toxic, serious oral administration can lead to death. The minimum lethal dose is: 640 mg/kg for adults, 8.6 g/kg for skin, 29 mg/kg for intravenous; 200 mg/kg for infants. The maximum allowable concentration in the air is 10 mg/m3.
Boric acid is a kind of skin astringent. It is mainly used for acute inflammatory process with water leakage and edema lesions clinically.
