Why Choose Kemaix Span 80 for Industrial Applications?
The Span 80 industrial benefits stem from its unique chemical stability and oil solubility. Our factory-standard Span 80 is rigorously tested for the following technical advantages:
- Low HLB Value (4.3): Ideal for emulsifying oils, fats, and solvents into water-in-oil systems.
- High Purity: Low acid value and controlled moisture content ensure consistent performance in sensitive pesticide and lubricant formulations.
- Excellent Bio-degradability: As a plant-based derivative, it meets modern environmental standards for green chemistry.
The Synergy: Pairing Span 80 with Tween 80
To maximize Span 80 industrial benefits, formulators often use it in combination with its hydrophilic counterpart, Tween 80. By adjusting the ratio of these two surfactants, you can achieve any desired HLB value between 4.3 and 15.0.
This “surfactant pairing” is the industrial standard for creating highly stable O/W emulsions in agrochemical EC (Emulsifiable Concentrate) formulations and high-end cosmetic creams, where Span 80 acts as the oil-phase stabilizer while Tween 80 ensures water-phase dispersion.
Recommended Dosage: Span 80 in Industrial Formulations
To fully leverage the Span 80 industrial benefits, precise dosage control is vital. Depending on the oil phase and required HLB, our technical lab recommends the following starting points:
| Industry Application | Recommended Dosage (%) | Primary Function |
|---|---|---|
| Agrochemical EC | 3% – 8% | Emulsification of active ingredients |
| Metalworking Fluids | 2% – 5% | Lubrication & Rust inhibition |
| Textile Auxiliaries | 1% – 3% | Softening & Anti-static base |
| Industrial Cleaning | 0.5% – 2% | Solubilization of organic grease |
Note: Kemaix suggests performing a compatibility test for each specific oil phase to determine the optimal surfactant ratio.
Technical FAQ
Q: What is the HLB value of Span 80 and why is it important?
A: Span 80 has an HLB value of approximately 4.3. This low value makes it an ideal primary emulsifier for Water-in-Oil (W/O) systems. It is also frequently paired with high HLB surfactants like Tween 80 to create stable O/W systems through precise HLB adjustment.
Q: How does Span 80 benefit the emulsion explosive industry?
A: In explosives, Span 80 acts as a critical stabilizer that prevents the crystallization of oxidizer salts. Its thermal resilience ensures the explosive remains stable and safe during long-term storage and high-temperature transport.
Q: Is Span 80 environmentally compliant?
A: Yes. Derived from natural fatty acids and sorbitol, Span 80 is biodegradable and aligns with modern “Green Chemistry” standards and environmental regulations.
Q: How does Span 80 improve quality in metalworking fluids?
A: It forms a robust interfacial film between the metal surface and the cutting oil, providing superior lubricity and rust protection while ensuring the fluid remains stable throughout repeated circulation cycles.
