Anhydrous Sodium Carbonate: pH Adjuster and Process Alkali
Anhydrous sodium carbonate (soda ash) is a fundamental alkaline salt used across pharmaceutical, food, and industrial applications. In pharmaceutical formulation, it functions as a pH adjuster and alkalizing agent. Its non-hygroscopic anhydrous form is preferred over the hydrated variants for applications requiring stable weight and consistent buffering capacity.

Formulation Applications
In pharmaceutical manufacturing, anhydrous sodium carbonate is used to adjust pH during synthesis and formulation of parenteral and oral liquid preparations. It is a component of effervescent tablet systems, where it reacts with citric or tartaric acid to generate carbon dioxide. In topical formulations, it can serve as an alkalizing agent to maintain target pH ranges. Industrially, it is a key raw material in glass production, detergent manufacture, and water softening. Formulators should note its strong alkalinity (pH ~11.5 in 1% solution) and potential incompatibility with acid-sensitive actives.
