- High Solubility: ≥80% solubility in water at 20°C with fast dissolution rate
- Thermal Stability: Suitable for high-tower spray drying processes
- Eco-Friendly: Non-toxic, biodegradable residue (sodium silicate) with no environmental pollution
- Cost-Effective: Lower production costs compared to phosphate-based alternatives
Recommended Applications
- Concentrated and regular washing powders
- Non-phosphorus laundry detergents
- Industrial cleaning agents (25-45% concentration)
- Metal cleaning solutions
- Dishwashing detergents (3-8% concentration)
- Washing pastes and liquid detergents
Packaging Options
Available in 25kg, 50kg, 500kg, or 1000kg woven PP bags with inner PE liners for optimal protection and handling.
Environmental Advantage
CSDS provides complete phosphate-free formulation, eliminating eutrophication risks while delivering superior cleaning performance. The final wash residue is non-toxic sodium silicate, safe for humans, animals, and aquatic life.
