Problems with Emulsifier A-105 (Nonylphenol Polyoxyethylene (10) Ether) in practical applications are usually related to factors such as imbalanced emulsification system ratio, abnormal water hardness, improper storage temperature or operational errors. It is recommended to first conduct a self-inspection based on product technical parameters and application requirements: check whether the product appearance is still a light yellow to yellow viscous liquid, whether there is delamination or turbidity; confirm whether the storage temperature is strictly controlled below 40°C and whether the container is sealed; verify whether there are any incompatible substances such as strong acids, strong bases or strong oxidants in the formula.
If the product itself shows quality abnormalities (such as packaging damage, appearance change, abnormal active substance content, etc.), stop using it immediately, properly seal the batch sample, and record the abnormal phenomenon, batch number, usage conditions and other information in detail to facilitate efficient traceability and analysis by the technical team.

| Problem Phenomenon | Possible Causes | Troubleshooting Suggestions |
|---|---|---|
| Emulsion unstable, delamination | 1. Insufficient amount of emulsifier; 2. Oil-to-water phase ratio exceeds emulsification range; 3. Water hardness too high | Adjust A-105 dosage or combine with other emulsifiers; test water quality, use soft water or add chelating agent if necessary |
| Poor wetting and penetration effect | 1. Low addition amount; 2. System pH value deviates from effective range; 3. Low temperature leads to increased viscosity | Appropriately increase the addition amount; test and adjust the system pH; control the material temperature within a suitable range |
| Product appearance becomes turbid or delaminated | 1. Storage temperature too low causing partial solidification; 2. Ingress of water or impurities; 3. Prolonged exposure to air leading to moisture absorption | The product's melting point is <0°C; thickening at low temperatures is normal; restore to room temperature and stir evenly; check container sealing to avoid impurity contamination |
| Decreased washing effect after use | 1. Deactivation of alkaline additives in the cleaning system; 2. Imbalance in the proportion of surfactants | A-105 has good alkali resistance; increase the amount of alkaline additives; re-optimize the surfactant compounding ratio |
| Excessive foaming affecting operation | 1. High usage concentration; 2. Excessive mechanical stirring; 3. Special foam restrictions in the application scenario | This product has moderate foaming properties; use a defoamer if necessary; reduce stirring speed or extend standing time |
When handling A-105, chemical safety goggles must be worn to prevent eye contact (this product is severely irritating to the eyes and can cause corneal damage). Skin contact may cause mild irritation; it is recommended to wear impermeable gloves. Do not discharge this product directly into water bodies, as it is toxic to aquatic organisms (fish LC₅₀ 1-10 mg/L). For more emergency treatment and safety information, please refer to the product safety data sheet or consult the technical department of Guoli Chemical.
