Performance and Usage

Dihydrate type contains one or two molecules of water of hydration and is slightly hygroscopic.The hydrated forms occur as white or transparent crystals or granules. All forms are freely soluble in water, but are insoluble in alcohol. The pH of a 1:100 solution is between 4.1 and 4.7.

It is mainly used as buffering agent, emulsification agent, nourishment, etc.
