Sodium hyaluronate is the sodium salt of hyaluronan. With the CAS NO. 9067-32-7, it is a visco-elastic polymer normally found in the aqueous and vitreous humour. It is also called Arthrease, Bio Hyaluro 12 , CCRIS 4127, Chlamyhyaluronic acid sodium salt. Sodium hyaluronate is a viscous solution consisting of a high molecular weight (500,000-730,000 daltons) fraction of purified natural sodium hyaluronate in buffered physiological sodium chloride. We should keep container tightly closed and keep container in a cool, well-ventilated area. Do not store above 8^°C (46.4^°F). Refrigerate. Store at tempertures from 2 - 8 ^°C.

Physical properties about Sodium hyaluronate are: (1)ACD/LogP: -1.131; (2)# of Rule of 5 Violations: 2; (3)ACD/LogD (pH 5.5): -3.85; (4)ACD/LogD (pH 7.4): -4.83; (5)ACD/BCF (pH 5.5): 1.00; (6)ACD/BCF (pH 7.4): 1.00; (7)ACD/KOC (pH 5.5): 1.00; (8)ACD/KOC (pH 7.4): 1.00; (9)#H bond acceptors: 12; (10)#H bond donors: 7; (11)#Freely Rotating Bonds: 10; (12)Flash Point: 432.5 °C; (13)Enthalpy of Vaporization: 131.19 kJ/mol; (14)Boiling Point: 791.6 °C at 760 mmHg; (15)Vapour Pressure: 5.77E-29 mmHg at 25°C

Uses of Sodium hyaluronate: Sodium hyaluronate is used as a viscosupplement, administered through a series of injections into the knee, increasing the viscosity of the synovial fluid, which helps lubricate, cushion and reduce pain in the joint. It is generally used as a last resort before surgery and provides symptomatic relief, by recovering the viscoelasticity of the articular fluid, and by stimulating new production from synovial fluid.

When you are using Sodium hyaluronate, please be cautious about it as the following:
1. Do not breathe dust;
2. Avoid contact with skin and eyes;
3. Wear suitable protective clothing, gloves and eye/face protection;
4. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
5. Take off immediately all contaminated clothing;
