Sodium Bicarbonate — Pharma & Food Grade Supplier, Hyderabad
Product Overview
Sodium Bicarbonate is an alkaline salt widely used as an effervescent agent, alkalising agent, and antacid active ingredient in pharmaceutical formulations. It reacts with citric or malic acid to produce COâ‚‚ gas, essential for effervescent tablets and sachets. Also used as a food-grade leavening agent.

What is the role of Sodium Bicarbonate in effervescent tablet formulations?
Sodium Bicarbonate is the alkaline component that reacts with an acid (Citric Acid, Malic Acid, or Tartaric Acid) to generate COâ‚‚ gas, producing the effervescent action when the tablet dissolves in water. The stoichiometric ratio of Citric Acid to Sodium Bicarbonate is approximately 1:1.14 (by weight) for complete neutralisation. Excess Sodium Bicarbonate produces an alkaline effervescent solution; excess acid produces an acidic solution.
How should Sodium Bicarbonate be stored to prevent premature COâ‚‚ loss?
Sodium Bicarbonate is sensitive to heat, humidity, and CO₂ in the air. Store in tightly sealed containers at controlled temperature (below 30°C) and relative humidity below 50%. In manufacturing, effervescent blends should be processed in humidity-controlled rooms (RH < 40%). Even small amounts of moisture can initiate the acid-base reaction, causing caking and loss of effervescent capacity.
Can Sodium Bicarbonate be used as an active antacid ingredient?
Yes. Sodium Bicarbonate is an approved antacid active ingredient that neutralises gastric acid rapidly. It acts within 1–2 minutes, making it faster than Calcium Carbonate or Aluminium Hydroxide-based antacids. However, its short duration of action and absorption of sodium limit use in patients with hypertension, heart failure, or renal impairment. Maximum OTC antacid dose is typically 300–600 mg per dose.
What is the difference between pharma-grade and food-grade Sodium Bicarbonate?
Pharma-grade Sodium Bicarbonate (IP/BP/USP) meets stricter limits for heavy metals, arsenic, and impurity levels compared to food-grade (E500) Sodium Bicarbonate. While food-grade is suitable for baking and general food use, pharma-grade must be used in oral pharmaceutical formulations. We supply both grades — please specify your requirement when ordering.
