Product Description

Ascorbic acid is a naturally occurring organic compound with antioxidant properties. It is a white solid, but impure samples can appear yellowish. It dissolves well in water to give mildly acidic solutions. Because it is derived from glucose, many animals are able to produce it, but humans require it as part of their nutrition. 

There exists a D-ascorbic acid, which does not occur in nature. It may be synthesized artificially. It has identical antioxidant properties to L-ascorbic acid yet has far less vitamin C activity (although not quite zero).

[Characteristics ] colorless crystals or a white or almost white, crystalline powder which discolors on exposure to air and moisture; Odorless or almost odorless and tasted sour; Easily soluble in water and a few partial soluble in ethanol; Insoluble in ether and chloroform.

[Product specification ] BP/USP/EP/JP/FCC

[Package]25kg net weight carton box or drum with two plastic inner linings and vacuum-sealed bag.

[Storage ]shielded from light, dry and cool placement, sealed for storage.
