Description
Ascorbic Acid Product Overview
Ascorbic acid (C6H8O6) is a white to slightly yellow crystalline powder that dissolves freely in water. It is a strong antioxidant and an essential nutrient that humans cannot produce themselves. In solution, it degrades in air, light and heat, so producers protect it during processing.
In addition, producers of nutritional products use it in tablets, effervescent tablets, chewables and powders, often in granular or directly compressible grades (for example 90–97% granulation). Similarly, food and beverage producers use it as an antioxidant (E300) to prevent browning and flavor loss in juices, beer, wine and processed meat, and bakeries use it as a flour improver. Pharmaceutical companies use pharmacopoeia grades in vitamin preparations and injections, and feed producers use coated forms in premixes.
Notably, cosmetic formulators use it as an antioxidant and brightening ingredient, often together with more stable derivatives such as Ascorbyl Palmitate. Related ingredients in our range include Calcium Ascorbate, Citric Acid Anhydrous and Vitamin E 50% (dl-α-Tocopheryl Acetate Powder).
