Applications

1. Food Additive (E339i) A food-grade acidity regulator and buffering agent for baking, dairy, beverage and processed meat applications. Pairs with leavening systems for controlled gas release, stabilizes pH and improves texture, delivering consistent quality in food production.

2. Water Treatment An effective pH conditioner and scale control agent in boiler and process water systems. Precise pH adjustment helps prevent scale formation and corrosion, protecting equipment and extending service life.

3. Detergents & Cleaning A builder and buffering agent in industrial and household detergents. Enhances cleaning performance and maintains optimal pH in hard-water conditions.

4. Ceramics & Metal Treatment A processing aid in ceramic and metal surface treatment applications. Consistent quality and high solubility support reliable process control and product quality.

5. Fertilizer & Specialty Applications A water-soluble phosphorus source for specialty fertilizer and nutrient formulations. High solubility and consistent assay support precise nutrient delivery in agricultural applications.
