Light Calcium Carbonate — Pharma Grade Supplier, Hyderabad
Product Overview
Light Calcium Carbonate has a lower bulk density and larger specific surface area than heavy grade, making it preferred for suspension formulations, toothpaste, and coating applications. It is used as an antacid, calcium supplement, food-grade additive, and filler in pharmaceutical and nutraceutical products.

Frequently Asked Questions
Where can I buy Light Calcium Carbonate IP/USP grade in Hyderabad?
Surravi Phharma supplies Light Calcium Carbonate in IP, BP, EP, and USP grades in Hyderabad. Ready stock. Used in oral suspensions, toothpaste, and tablet formulations. Call +91 8008002576.
Why is Light Calcium Carbonate preferred for oral suspension formulations?
Light Calcium Carbonate has a much higher specific surface area and lower particle density than the heavy grade, giving it better suspension characteristics. It disperses more easily in aqueous suspension vehicles and produces more stable, uniform suspensions with less tendency to cake or hard-pack at the bottom.
What is the role of Light Calcium Carbonate in toothpaste?
Calcium Carbonate is the most widely used mild abrasive in toothpaste formulations. The light grade is preferred because its fine particles effectively remove plaque and stains without scratching tooth enamel. It is also a whitening agent and provides a calcium source that may benefit remineralisation of early enamel lesions.
Can Light Calcium Carbonate be used as a food calcium fortification agent?
Yes. Light Calcium Carbonate is widely used for calcium fortification of food products including flour, breakfast cereals, dairy alternatives (soy milk, almond milk), and fruit juices. It is the most economical and highest-elemental-calcium food fortifier approved under FSSAI regulations.
What are the particle size differences between Light and Heavy Calcium Carbonate?
Light Calcium Carbonate typically has a median particle size of 1–10 μm with high surface area (10–40 m²/g). Heavy Calcium Carbonate has larger particles (10–40 μm median) with lower surface area (<5 m²/g). The finer particles of light grade dissolve and disperse more readily, while the coarser heavy grade flows better in direct compression tablet presses.
