How to Make Sodium Formaldehyde Sulfoxylate (Rongalite)?

October 21, 2025

Q: How to make sodium formaldehyde sulfoxylate?

A: Sodium Formaldehyde Sulfoxylate, commonly known as Rongalite, is produced by reacting formaldehyde and sodium bisulfite in the presence of zinc dust and zinc oxide as reducing agents. The reaction must be carefully controlled to ensure stability and purity. Afterward, a purification process removes impurities and moisture, resulting in a fine white crystalline powder that serves as a powerful reducing and bleaching agent in various industrial applications, such as textile dyeing, polymerization, and chemical synthesis.

In the Turkish and Pakistani markets, sodium formaldehyde sulfoxylate is in strong demand due to its essential role in textile bleaching and color stripping. Buyers in these regions often face challenges such as inconsistent product quality, moisture sensitivity during shipping, and limited local supply. Reliable sourcing from certified manufacturers is therefore critical to maintaining product performance and production efficiency.
