Diammonium citrate
Description
Diammonium citrate (CAS 3012-65-5), also known as dibasic ammonium citrate, is a water-soluble ammonium salt of citric acid used across food, personal care, and industrial applications. It serves as a buffering agent, chelator, and pH regulator.
This chemical controls acidity in formulations and binds metal ions that would otherwise destabilize finished products. In food and beverage production, it functions as an acidulant and buffering salt to maintain target pH ranges during processing.
Personal care formulators incorporate it into rinse-off and leave-on products where metal ion sequestration prevents discoloration and preservative degradation. This ensures the long-term stability and aesthetic quality of cosmetic formulations.
Water treatment applications rely on its chelating action to complex calcium, magnesium, and heavy metal ions. This process significantly improves the overall performance and efficiency of various industrial treatment chemicals.
It also appears in fertilizer formulations as a soluble nitrogen and citrate source compatible with micronutrient blends. This versatility makes it a valuable component in modern agricultural and horticultural nutrient management systems.
The product is supplied as a white crystalline powder or granule. Food-grade material is available to FCC specification, while technical-grade product is offered for industrial and agricultural use to meet specific requirements.
Bulk supply is standard in 25 kg bags, with larger packaging available for industrial volumes. We ensure consistent quality and reliable logistics for all global shipments of this essential chemical compound.
