Description

Poly-(Alpha,Beta)-Dl-Aspartic Acid Sodium Salt is a biodegradable, water-soluble polymer derived from aspartic acid. This compound serves as a high-performance, environmentally friendly alternative to traditional polyacrylates in scale and corrosion inhibition. It is essential for industries requiring effective water treatment solutions, biodegradable chelating agents, and green polymer additives. Key markets include water treatment, detergent formulation, agriculture, and personal care.

Application

• Water Treatment: Acts as a highly effective, biodegradable scale inhibitor and dispersant for cooling water, boiler water, and reverse osmosis systems.
• Detergents & Cleaners: Used as a builder and co-builder to enhance cleaning power, sequester calcium and magnesium ions, and improve phosphate-free detergent formulations.
• Agriculture: Functions as a nutrient enhancer and chelating agent in fertilizers to improve micronutrient availability for plants.
• Personal Care: Employed in cosmetics and personal care products as a gentle, biodegradable chelating agent and viscosity modifier.
• Oilfield Chemicals: Utilized in drilling and production fluids for scale control and as a green corrosion inhibitor.
• Pulp & Paper: Serves as a dispersant and chelant in bleaching processes and paper manufacturing.
• Textile Industry: Applied in dyeing and finishing processes as a dispersing and leveling agent.
• Industrial Cleaners: A key ingredient in industrial and institutional (I&I) cleaning formulations for its sequestration and anti-redeposition properties.

Quality Control

Our Poly-(Alpha,Beta)-Dl-Aspartic Acid Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, purity, and compliance with relevant industry standards. Certificates of Analysis (COA) detailing key parameters such as assay, molecular weight distribution, and residual solvents are available upon request.

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). Keep the container tightly sealed to prevent absorption of moisture from the air, which can affect product performance and flow characteristics.
