Tween 80 is a classic nonionic surfactant. Problems encountered during use are usually related to poor emulsification, incomplete dissolution, product delamination, or low-temperature effects. First, check whether the storage conditions meet the requirements (cool, dry, ventilated, 10-30°C). Because Tween 80 is hygroscopic, prolonged exposure to humid air may increase its moisture content and affect performance. Second, confirm the pH environment during use—this product will hydrolyze under strong acid or strong alkaline conditions, which may lead to performance degradation.
If the problem is related to the formulation application, it is recommended to investigate from the following aspects: whether the HLB value of the system matches, whether the addition sequence is correct, whether there are incompatible additives (e.g., strong oxidizers), and whether the water temperature or stirring is sufficient. The HLB value of Tween 80 is 15, suitable for O/W emulsification systems. If the required HLB value of the oil phase deviates greatly, the emulsification effect will be significantly weakened. Its cloud point is approximately 93°C (1% aqueous solution). If the operating temperature approaches or exceeds the cloud point, the surface activity will drop sharply, leading to demulsification or turbidity.
If the above self-check still does not resolve the issue, or if you encounter batch quality problems or technical difficulties, the most direct and effective approach is to contact the product supplier or manufacturer. You can call Guoli Chemical's sales or technical support hotline and explain to the technician the specific application scenario, dosage ratio, process conditions, and abnormal phenomena observed. It is recommended to prepare the batch number, usage records, and environmental parameters in advance so that the technician can quickly locate the problem.
The following are key technical indicators closely related to troubleshooting. You can refer to them when communicating with the technician:
| Parameter Item | Typical Value | Impact on Usage |
|---|---|---|
| Appearance | Light yellow to amber liquid | Significant darkening may indicate oxidation or decomposition |
| HLB Value | 15 | Determines emulsification/solubilization suitability; deviation affects emulsion stability |
| Cloud Point (1% aqueous solution) | Approx. 93°C | Operating temperature approaching or exceeding this value leads to functional failure |
| pH of 1% Aqueous Solution | 5.0–7.0 | Deviation from normal range indicates possible product deterioration |
| Moisture Content | ≤3.0% | Increased moisture after moisture absorption reduces effective component ratio |
| Chemical Stability | Hydrolyzes under strong acid/alkali | Extreme pH environment damages product structure, loses emulsifying power |
| Active Substance Content | ≥97% | Directly affects effective dosage |
