### Common Troubleshooting Directions for Abnormal Use
- **Poor Emulsification/Solubilization**
Possible causes: Improper HLB matching, influence of electrolytes/co-solvents, changes in oil phase type, incorrect addition order.
Recommended actions: Verify the required HLB value of the oil phase, adjust EL-60 dosage (usually 5-15% of the oil phase); try compounding with nonionic or anionic co-emulsifiers, and ensure the system pH is within 5-9, avoiding strong acids or bases that may cause demulsification.
- **System Stratification, Turbidity, or Gel Formation**
Possible causes: Low temperature causing paste precipitation, high water hardness (calcium/magnesium ions), incompatibility with cationic substances.
Recommended actions: Heat the material to 40-50°C and stir for homogenization; for hard water systems, add 0.1-0.5% chelating agent (e.g., EDTA-2Na); if cationic components are present, dilute them first before stirring into the system.
- **Excessive Foam or Insufficient Wetting**
Possible causes: EL-60 itself is low-foaming, but other surfactants in the formulation cause foam; insufficient wetting is often due to low concentration or substrate contamination.
Recommended actions: Appropriately reduce stirring speed, or add a small amount of defoamer (e.g., Guoli Chemical silicone defoamer); increase the working concentration of EL-60 to 0.2-0.5% and clean the substrate surface.
