    Qualified Organic Vitamin C Crystals Ascorbic Acid 100 Pure Powder Colourless

    Qualified Vitamin C colourless Cystalline Powder with ISO certificates


    Ascorbic Acid is well-known for its antioxygenation. 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. So it is called antioxidant. It must be stored in cold and dark place. Because it can oxidate the touched metals, it can not be stored in metal vessels.


    Characters and Performances:


    Vitamin C is white and slightly yellow crystalline powder with no odour. It is easily dissolved in water and the solubility at 20℃ is 33g/100g. It can not be dissovled in vegetable oil, slightly dissoved in ethanol (solubility is only 2g/100g). The color of Vitamin C will get darker when being light and it is stable in the dry conditions. Heat and light can destroy easily the solution of Vitamin C, especially in the alkaline condition and in the presence of metal. So it should pay more attention to avoid metals and air touch in water and containers.
