Sodium Dithionite 88%

Sodium Dithionite 88%, also known as Sodium Hydrosulfite, is a white crystalline powder with a weak sulfurous odor. It is a sodium salt of dithionous acid. Although it is stable under most conditions, it will decompose in hot water and in acid solutions. This compound is a water-soluble salt and can be used as a reducing agent in aqueous solutions.

This product is commonly used in industrial dyeing processes as a reducing agent. It helps reduce otherwise water-insoluble dyes into water-soluble alkali metal salts, improving overall color quality. Additionally, the reduction properties of Sodium Dithionite eliminate excess dye, residual oxide, and unintended pigments, making it an ideal product for dyeing processes.

Key Features:

• White crystalline powder with a weak sulfurous odor
• Water-soluble salt and can be used as a reducing agent in aqueous solutions
• Improves overall color quality in industrial dyeing processes
