Description

Diammonium Malate is a high-purity, water-soluble ammonium salt of malic acid, widely recognized for its buffering and chelating properties. This compound is essential for applications requiring precise pH control and metal ion sequestration in sensitive formulations. It serves as a critical raw material for manufacturers in the pharmaceutical, food & beverage, and personal care industries seeking reliable, high-quality ingredients.

Application

• Pharmaceutical Buffer & Excipient: Used in the formulation of injectables, ophthalmic solutions, and oral medications to maintain stable pH and improve stability.
• Food Additive & Acidity Regulator: Functions as a pH control agent and flavor enhancer in beverages, confectionery, and processed foods.
• Cosmetic & Personal Care Ingredient: Acts as a skin conditioning agent and pH adjuster in creams, lotions, and serums.
• Nutrient Source in Fermentation & Cell Culture: Provides a readily available nitrogen and carbon source in microbial fermentation media and biotechnological processes.
• Industrial Chelating Agent: Used in water treatment and cleaning formulations to control scale and sequester metal ions like calcium and magnesium.
• Chemical Intermediate: Serves as a precursor in organic synthesis for further chemical modifications.
