Description

Tris(2-Hydroxyethyl)Ammonium Trihydrogen Ethylenediaminetetraacetate is a specialized organic salt of ethylenediaminetetraacetic acid (EDTA) designed for enhanced solubility and stability in aqueous formulations. This compound is valued for its powerful chelating properties, effectively sequestering di- and trivalent metal ions to prevent unwanted catalytic activity and precipitation. It is a critical component for industries requiring high-purity metal deactivation, such as pharmaceutical manufacturing, personal care, and advanced chemical synthesis.

Application

• Pharmaceutical Stabilizer: Used in injectable and ophthalmic solutions to chelate trace metals that can catalyze drug degradation, thereby extending shelf-life.
• Cosmetic & Personal Care Preservative Booster: Enhances the efficacy of preservative systems in creams, lotions, and shampoos by inactivating metal contaminants.
• Industrial Cleaning & Descaling Agent: A key ingredient in formulations for removing limescale and metal oxide deposits from boilers and heat exchangers.
• Textile Processing Aid: Prevents metal-ion interference during dyeing and bleaching processes to ensure consistent color and fabric quality.
• Laboratory Reagent: Serves as a buffer component and metal chelator in molecular biology and analytical chemistry applications.
• Agricultural Chemical Additive: Improves the stability and bioavailability of micronutrients in liquid fertilizer and pesticide formulations.

Quality Control

Our Tris(2-Hydroxyethyl)Ammonium Trihydrogen Ethylenediaminetetraacetate is manufactured under a cGMP-compliant quality management system. Each batch undergoes rigorous analytical testing to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting purity, assay, and heavy metal content are provided with every shipment to guarantee traceability and compliance for sensitive applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
