Description

Bis[Bis(2-Hydroxyethyl)Ammonium] Sulphite is a specialized organosulfur compound that serves as a versatile reducing agent and stabilizer. Its molecular structure, featuring dual ethanolamine moieties, provides excellent solubility and reactivity in aqueous and polar systems, making it a critical additive for controlling oxidation and degradation processes. This chemical is essential for manufacturers in the polymer, textile, and personal care industries seeking to enhance product shelf-life and performance under demanding conditions.

Application

• As a polymerization inhibitor and stabilizer in the production of acrylics, vinyl monomers, and synthetic rubbers to prevent premature cross-linking.
• As an oxygen scavenger and reducing agent in water treatment formulations and boiler feedwater systems to control corrosion.
• As a hair dye and cosmetic ingredient stabilizer, preventing the oxidation of active components in permanent wave solutions and colorants.
• As a textile processing auxiliary in bleaching and dyeing baths to improve color fastness and fiber protection.
• As a photographic chemical in developing solutions as a preservative.
• As a intermediate in organic synthesis for introducing sulfonate or sulfite functional groups.

Quality Control

Our Bis[Bis(2-Hydroxyethyl)Ammonium] Sulphite is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

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 and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to minimize moisture uptake and oxidative degradation. Keep away from strong oxidizing agents.
