Description:

Vitamin C is a colorless crystal, odourless, acidic taste. Soluble in water and ethanol. Stable in dry air , and its solution is not stable. As well as, vitamin C takes part in many metabolism procedures in the human body, helps decrease brittleness of blood capillaries and increase body resistance 
Vitamin C is widely used in many fields such as food , beverage, breeding and forage additives. Its main functions reflected in following 5 aspects:

Application:
Vitamin C is a well-known anti-oxidant. Its effect on free-radical formation when topically applied to the skin by means of a cream has not been clearly established. The effectiveness of topical applications has been questioned due to vitamin C's instability (it reacts with water and degrades). Some forms are said to have better stability in water systems. Synthetic analogues such as magnesium ascorbyl phosphate are among those considered more effective, as they tend to be more stable. When evaluating its ability to fight free-radical damage in light of its synergistic effect with vitamin e, vitamin C shines. As vitamin e reacts with a free radical, it, in turn, is damaged by the free radical it is fighting. Vitamin C comes in to repair the free-radical damage in vitamin e, allowing e to continue with its free-radical scavenging duties.
