Product Description
Ascorbic Acid (Vitamin C)
CAS No.: 50-81-7
Molecular formula: C6H8O6
M. W.: 176
Description: White crystal or crystalline powder.
Packing: 25kgs per carboard drum, 13mts/20FCL
Use:
Ascorbic acid is added to many foods for its nutritive value, but is also used extensively as an anti-oxidant, to prevent flavors and colors from being damaged by oxidation. It is often used in canned or frozen fruits to prevent the browning that accompanies oxidation.
Stores:
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from any source of heat or ignition. Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); Observe all warnings and precautions listed for the product.
