Description

Sodium Dihydrogen Propane-1,2,3-Triolate is the sodium salt of citric acid, a key organic acid widely used as a multifunctional additive. This compound is valued for its excellent chelating, buffering, and sequestering properties, making it a versatile ingredient in numerous industrial processes. It is essential for manufacturers in the food & beverage, pharmaceutical, detergent, and water treatment industries seeking a safe and effective agent for pH control, metal ion complexation, and stabilization.

Application

• Food & Beverage Industry: Used as an acidity regulator, flavor enhancer, and preservative in soft drinks, jams, and processed foods.
• Pharmaceuticals: Serves as an excipient in formulations for its buffering capacity and as a chelating agent in active pharmaceutical ingredients (APIs).
• Detergents & Cleaning Agents: Acts as a water softener and builder in liquid and powder detergents, enhancing cleaning efficiency by sequestering calcium and magnesium ions.
• Water Treatment: Employed to prevent scale formation in boilers and cooling systems by chelating metal ions that cause hardness.
• Industrial Cleaning: A key component in acid-free descaling solutions and metal surface treatment baths.
• Cosmetics & Personal Care: Functions as a pH adjuster and chelating agent in creams, lotions, and shampoos to improve stability.
• Agriculture: Used in certain fertilizer formulations and as a chelating agent in micronutrient supplements.
• Chemical Synthesis: Acts as a buffer and catalyst in various organic synthesis reactions.

Quality Control

Our Sodium Dihydrogen Propane-1,2,3-Triolate is manufactured under a strict quality management system. We offer grades compliant with Food Chemical Codex (FCC), USP/Pharmaceutical, and industrial standards. Every batch undergoes rigorous testing including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting purity, heavy metals, and other critical parameters are available upon request to ensure full traceability and compliance for your application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
