Overview
Anhydrous citric acid (TTCA grade) is a high‑purity, low‑moisture form of citric acid produced under strict quality control. Its improved flowability and consistent particle size distribution make it ideal for applications requiring precise dosing, rapid dissolution, and long‑term stability. The anhydrous form is preferred in dry blends, effervescent tablets, and formulations where water content must be minimized.

Key Features

• Low moisture content – prevents premature reactions and improves shelf life.

• Excellent flowability – facilitates handling, blending, and tableting.

• Rapid dissolution – ensures complete solubility in aqueous systems.

• High purity – consistent quality with low impurity levels.

• Versatile functionality – acts as acidulant, chelator, buffer, and effervescent agent.

Applications

• Food and beverages: Used as an acidity regulator, flavor enhancer, and preservative in soft drinks, juices, jams, candies, and dairy products.

• Pharmaceuticals: Acts as an excipient in effervescent tablets, buffer systems, and as a stabilizer in formulations.

• Household and industrial cleaning: Used as a chelating agent for metal ions, descaling agent, and component in detergent formulations.

• Cosmetics: Provides pH adjustment and chelation in skincare and personal care products.

• Other uses: In metal treatment, water softening, and as a reagent in chemical synthesis.

Storage and Handling

• Store in a cool, dry place, away from moisture and direct sunlight.

• Keep containers tightly sealed to prevent caking and contamination.

• Use appropriate personal protective equipment (gloves, dust mask, safety goggles) when handling.

• Avoid contact with strong oxidizers and bases.

Quality Assurance
Each batch is tested for purity, moisture content, heavy metals, and particle size distribution to ensure compliance with food, pharmaceutical, and industrial standards.
