Description

2,3-Oxiranedicarboxylic Acid, Disodium Salt, Homopolymer is a high-purity, water-soluble polycarboxylate polymer derived from epoxysuccinic acid. This compound matters for its exceptional performance as a biodegradable and non-phosphorous scale inhibitor and dispersant, offering a more environmentally friendly alternative to traditional additives. Industries such as water treatment, detergent formulation, and industrial cleaning need it for its superior chelating and threshold inhibition properties against calcium carbonate and other mineral scales.

Application

• Industrial Water Treatment: Primary application as a highly effective, biodegradable scale inhibitor and dispersant in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Used as a co-builder and anti-redeposition agent in phosphate-free laundry detergents, dishwashing liquids, and industrial cleaners.
• Pulp & Paper Industry: Acts as a dispersant and chelant in pulp bleaching and papermaking processes to control scale and improve efficiency.
• Textile Processing: Employed as a sequestering agent and anti-precipitant in dyeing and finishing operations to prevent metal ion interference.
• Oilfield Chemicals: Serves as a scale inhibitor in squeeze treatments and production fluids to prevent mineral scale deposition in wells and pipelines.
• Personal Care Products: Potential use in formulations as a gentle chelating agent to stabilize products and enhance performance.

Quality Control

Our 2,3-Oxiranedicarboxylic Acid, Disodium Salt, Homopolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and compliance with industry standards. Key parameters such as active content, pH, and viscosity are closely monitored. A comprehensive Certificate of Analysis (COA) detailing purity and specifications is available for every shipment 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 when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
