Citric Acid Anhydrous EX China 25kg - Specification
Citric Acid Anhydrous is the anhydrous form of citric acid, meaning it does not contain any water molecules, unlike the monohydrate form, which contains one water molecule per citric acid molecule. Citric acid anhydrous is commonly used in applications requiring high acidity and purity, such as in the food, pharmaceutical, cosmetic, and chemical industries.
Here’s the typical specification for Citric Acid Anhydrous EX China 25kg:
