Physical properties about Sodium perborate tetrahydrate are: (1)#H bond acceptors: 3; (2)#H bond donors: 1; (3)#Freely Rotating Bonds: 2; (4)Polar Surface Area: 35.53Å2; (5)Exact Mass: 155.033903; (6)MonoIsotopic Mass: 155.033903; (7)Topological Polar Surface Area: 50.5; (8)Heavy Atom Count: 9; (9)Complexity: 17.2; (10)Covalently-Bonded Unit Count: 6.

Preparation of Sodium perborate tetrahydrate. Firstly, solid sodium hydroxide is dissolved and mixed with borax. Then the mixture solution is filtered to remove insoluble substance after fully mixing. Secondly, magnesium silicate stabilizer and hydrogen peroxide are added for reaction at the temperatures not exceeding 35 °C. Finally, product is obtained by crystallization, centrifugation and drying.

Na2B4O7 + 2 NaOH + H2O2 + 11 H2O→4 NaBO3·4 H2O

When you are using this chemical, please be cautious about it. As a chemical, it is irritating to eyes, respiratory system and skin. It is harmful if swallowed and contacts with combustible material may cause fire. During using it, wear suitable protective clothing, gloves and eye/face protection. Keep away from combustible material. If contact with eyes accidently, rinse immediately with plenty of water and seek medical advice.
