Key Characteristics
- Appearance: Typically white to off-white powder or paste
- Solubility: Readily soluble in water
- Dispersibility: Excellent
- Surface activity: High
- Electrolyte stability: Strong
- Hard water compatibility: Good
Performance Advantages
✔ Excellent detergency
✔ Strong permeability (rapid wetting)
✔ Good foam formation
✔ Stable in high electrolyte systems
✔ Effective dispersing capability
Compared with longer-chain sulfates (such as C12 types), sodium n-decyl sulfate often provides faster wetting and penetration, making it particularly suitable for industrial processes requiring rapid surface interaction.
Industrial Applications

Role in Emulsion Polymerization
Sodium n-decyl sulphate (GF-G) is widely used in emulsion synthesis systems.
- Solubilizer
- Wetting agent
- Auxiliary emulsifier
- Dispersant for poorly soluble monomers
- Vinyl acetate
- Acrylates
- Other water-borne polymer systems
In emulsion synthesis, it:
- Reduces surface tension
- Stabilizes polymer particles
- Promotes uniform particle size distribution
- Improves dispersion of hydrophobic substances
This makes it highly valuable in coatings, adhesives, latex production, and polymer manufacturing.
Key Advantages in Polymer Systems
✔ Enhances emulsion stability
✔ Improves particle dispersion
✔ Supports fine particle size control
✔ Good compatibility with co-surfactants
✔ Maintains stability under electrolyte conditions
