Description

Sodium Aminosuccinate is the sodium salt of aspartic acid, a key amino acid derivative. This compound serves as a versatile and effective chelating agent and biochemical intermediate, offering superior metal ion sequestration capabilities. It is essential for manufacturers in the personal care, pharmaceutical, and industrial cleaning sectors who require a biodegradable and skin-friendly alternative to traditional chelators. Its high purity and consistent quality make it a reliable choice for demanding formulations.

Application

• Personal Care & Cosmetics: Used as a gentle yet effective chelating agent in shampoos, conditioners, and skin creams to stabilize formulations by binding metal ions that can cause spoilage or discoloration.
• Pharmaceutical Intermediates: Acts as a crucial building block in the synthesis of active pharmaceutical ingredients (APIs) and various peptide-based drugs.
• Biodegradable Chelators: Serves as a core component in environmentally friendly cleaning agents, detergents, and water treatment solutions where traditional phosphates are restricted.
• Food & Nutrition: Employed as a flavor enhancer and a nutrient source in specialized dietary supplements and food fortification processes.
• Agricultural Chemicals: Functions as a chelating agent in micronutrient fertilizers, enhancing plant uptake of essential minerals like iron and zinc.
• Industrial Processes: Utilized in metal finishing, electroplating baths, and as a scale inhibitor in cooling water systems to control water hardness.

Quality Control

Our Sodium Aminosuccinate is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and cosmetic applications. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, optical rotation, heavy metals, and residual solvents. Our quality commitment aligns with cGMP principles, and we can support compliance with relevant pharmacopoeial standards (e.g., USP, EP) upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
