What is the difference between Citric Acid Anhydrous and Monohydrate?
Citric Acid Anhydrous contains no water of crystallisation and is preferred in moisture-sensitive formulations and dry effervescent blends. Monohydrate has ~8.5% water content and is used where a more stable crystalline form is needed. Both are pharmacopoeially equivalent in terms of assay.
Can Citric Acid Anhydrous be used in effervescent tablet manufacturing?
Yes — it is one of the two primary components in effervescent systems, reacting with Sodium Bicarbonate to release CO₂. Anhydrous grade is strongly preferred over monohydrate in effervescent manufacturing to avoid premature reaction from moisture.
Is pharma-grade Citric Acid Anhydrous food safe?
Yes. Citric Acid Anhydrous meeting IP/BP/USP specifications also complies with food-grade standards (E330). It is approved for use in food, beverages, and pharmaceutical oral preparations.
