Sodium hyaluronate occurs as white to off-white powder or granules. It is very hygroscopic. 

Sodium hyaluronate should be stored in a cool, dry place in tightly sealed containers. The powder is stable for three years if stored in unopened containers.

The sample used was hyaluronate (sodium salt, of microbial origin) in the form of a white powder and with a MW of 0.7 to 0.9 MDa. It was kept in dry conditions in a desiccator (at the ambient temperature of 24 °C) for 4 weeks prior to the SEA and powder rheology experiments.
