keep low-temperature drying and avoid sunlight
Sodium Erythorbate is White crystalline powder,Slightly salty. It is quite stable in the air in a dry state. But in solution, it will deteriorate in the presence of air, trace metals, heat and light. Melting point above 200 ℃ (decomposition). Easily soluble in water (17g / 100m1). Almost insoluble in ethanol. The pH value of the 2% aqueous solution is 5.5 to 8.0.
Used as food antioxidants, anti-corrosion color additives, Cosmetic antioxidants. It can consume oxygen in cosmetics, reduce high-valent metal ions, transfer the redox potential to the reduction range, and reduce the generation of undesirable oxidation products. It can also be used as anticorrosive color additive.
