Applications

Chemical Overview

Sodium Formaldehyde Sulphoxylate (SFS), also known as Rongalite (CAS 149-44-0/6035-47-8), is a water-soluble white crystalline powder. As a powerful reducing agent, it releases formaldehyde and sulfoxylate ions under controlled conditions, making it essential in textile bleaching, polymer synthesis, and dye stripping.

Environmental & Safety Profile

Rongalite (SFS) decomposes into non-persistent byproducts like sulfates and formaldehyde, requiring strict handling protocols. Industrial-grade SFS (CAS 149-44-0) is classified as non-flammable but necessitates ventilation to avoid inhalation risks.

Textile Dyeing Innovations

SFS enables low-temperature dye stripping in denim processing, minimizing energy use and fabric damage. Its compatibility with eco-friendly dyes aligns with sustainable fashion industry standards.
