Product Details

Potassium Citrate Anhydrous

Product Overview

Potassium Citrate Anhydrous is a high-purity potassium salt of citric acid produced without crystal water, offering significantly lower moisture content than the monohydrate grade. With a moisture content of not more than 1.0%, it provides superior storage stability, higher active ingredient concentration, and improved processing performance for food, pharmaceutical, nutraceutical, and industrial applications.

Jiangsu Khonor Chemicals Co., Limited supplies premium-quality Potassium Citrate Anhydrous manufactured under strict quality management systems. The product is available in Food Grade, Pharmaceutical Grade (USP/EP), and Industrial Grade to meet various international market requirements.

Key Advantages of Potassium Citrate Anhydrous

Ultra-Low Moisture Content

Compared with Potassium Citrate Monohydrate, the anhydrous grade contains less than 1.0% moisture, significantly reducing the risk of moisture absorption and caking during storage and transportation.

Higher Active Ingredient Content

Without crystal water, every kilogram contains a higher proportion of active potassium citrate, improving formulation efficiency and reducing dosage adjustments.

Better Storage Stability

The low-moisture structure helps maintain product quality during long-term storage, especially in humid environments.

Improved Flowability

Lower moisture contributes to better powder flow, making it suitable for automatic filling, blending, and tablet manufacturing.

Longer Shelf Life

Reduced water content minimizes quality deterioration caused by moisture, helping maintain consistent performance throughout storage.
