    Ascorbic Acid is well-known for its antioxygenation. So it is called antioxidant. Most people are familiar with L-Ascorbic Acid also called Vitamin C. When it is not vitamin format, ascorbic acid was often used for film production. Ascorbic acid is easy to be oxydated, but it can prevent different cells from damaging. It must be stored in cold and dark place. Because it can oxidate the touched metals, it can not be stored in metal vessels.
