Applications of Sodium Formaldehyde Sulfoxylate (Rongalit C) and its derivatives:
🔹 Applications of Sodium Formaldehyde Sulfoxylate (Rongalit C)
Textile Industry
-
VAT dyeing: Acts as a reducing agent, helping dyes dissolve and bond to fabrics.
-
Stripping and discharge processes: Removes excess dye or chemicals from fabrics.
-
Softening and flexibility: Enhances fabric comfort and elasticity, improving wearability.
Rubber & Plastics
-
Redox activator: Speeds up and stabilizes rubber polymerization reactions.
-
Polymerization regulator: Functions as a catalyst to control chain structure in plastics.
-
Emulsion polymerization: Serves as a reducing agent in redox-catalyzed systems.
Paints & Adhesives
-
Pigment production: Used as a raw material in dye and paint formulations.
-
Adhesives: Acts as an emulsifier in food packaging adhesives, improving bonding and stability.
Food & Packaging
-
Bleaching agent: Applied in soap and molasses production to lighten color.
-
Packaging materials:
-
Catalyst/emulsifier in paperboard and rubber products that contact food.
-
Used in sealing gaskets for food containers.
-
-
Emulsifier: Ensures homogeneity in adhesives and rubber products intended for food contact.
Pharmaceuticals
-
Antioxidant: Prevents oxidation in certain drug formulations.
-
Mercury poisoning treatment: Active ingredient in medications used for detoxification.
🔹 Bruggolite Product Variants

🔹 Notes
-
Bruggolite® E01 → Preferred in powder/granule form, dissolves quickly, suitable for both acidic and alkaline systems.
-
Bruggolite® L40 → Ready-to-use aqueous solution, avoids handling solid SFS.
-
Formaldehyde-free grades (Brüggemann) → Environmentally safer, FDA-approved for direct food contact, higher reactivity allows lower dosage.
