Description

2,2'-Oxydisuccinic Acid is a high-purity, biodegradable chelating agent and sequestrant derived from succinic acid. This compound matters for industries seeking effective, environmentally friendly alternatives to traditional phosphonates and EDTA for controlling metal ions in aqueous systems. Key sectors that need it include industrial cleaning, water treatment, pulp & paper processing, and textile manufacturing, where it prevents scale formation and stabilizes peroxides.

Application

• Industrial & Institutional (I&I) Cleaning: Acts as a powerful builder and chelant in detergent formulations, enhancing cleaning efficiency by sequestering calcium and magnesium ions.
• Water Treatment: Used for scale inhibition and dispersion in cooling water, boiler water, and reverse osmosis systems.
• Pulp & Paper Bleaching: Serves as a stabilizing agent for hydrogen peroxide, improving brightness and yield in the bleaching process.
• Textile Processing: Functions as a chelant in scouring, bleaching, and dyeing baths to prevent metal-ion catalyzed degradation of fibers and dyes.
• Personal Care: Employed as a chelating agent in shampoos, soaps, and other formulations to improve stability and shelf life.
• Agriculture: Can be used in micronutrient fertilizers to enhance the bioavailability of essential metals like iron and zinc.
