Description

Glycine, N-(Carboxymethyl)-N-2-(2-Hydroxyethoxy)Ethyl-, Disodium Salt is a high-purity, water-soluble organic salt derived from glycine, functioning as a versatile chelating agent and stabilizer. Its molecular structure provides excellent sequestering power for metal ions, making it critical for preventing unwanted precipitation and catalytic degradation in sensitive formulations. This compound is essential for manufacturers in the personal care, pharmaceutical, and industrial cleaning sectors who require reliable, high-performance ingredients to ensure product stability and shelf life.

Application

• Personal Care & Cosmetics: Acts as a highly effective chelating agent in shampoos, creams, and lotions to bind metal ions (e.g., calcium, magnesium) that can cause product instability, discoloration, or rancidity.
• Pharmaceutical Formulations: Used as a stabilizer and buffering agent in injectable solutions and topical preparations to enhance shelf life and maintain pH stability.
• Industrial & Institutional (I&I) Cleaners: Serves as a key component in liquid detergents and hard surface cleaners to improve cleaning efficiency by sequestering water hardness ions and preventing soap scum.
• Textile & Leather Processing: Employed in dyeing and finishing baths to chelate metal ions that could interfere with dye uptake and uniformity, ensuring vibrant and consistent color results.
• Agrochemicals: Functions as a compatibility agent and stabilizer in liquid fertilizer and pesticide formulations, preventing nutrient lock-up and degradation.
• Water Treatment: Utilized in boiler and cooling water systems to control scale formation by sequestering scale-forming cations like calcium and magnesium.

Quality Control

Our Glycine, N-(Carboxymethyl)-N-2-(2-Hydroxyethoxy)Ethyl-, Disodium Salt is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed after each use to prevent absorption of atmospheric moisture, which may affect product quality.
