Polyether L-35 (Poloxamer 105) is a highly stable nonionic surfactant that rarely causes serious issues under normal usage conditions. If you encounter abnormalities during use, it is recommended to follow these steps for troubleshooting: First, confirm whether the product appearance is a colorless to slightly yellow transparent liquid. If turbidity, stratification, or precipitation occurs, it usually indicates that the product may have failed due to improper storage (e.g., freezing, prolonged high temperature, or unsealed container causing moisture absorption and deterioration). In such cases, stop using and replace with a new batch.
Second, check the conditions of the formulation system. Although Polyether L-35 has broad chemical compatibility and remains active in acidic, alkaline, and hard water environments, sharing it with incompatible substances such as strong oxidizers may lead to performance degradation. Additionally, if foam performance is abnormal (excessive or insufficient wetting), verify whether the dosage is within the recommended range and whether other high-foaming surfactants have been introduced into the system, causing interference.
If the problem cannot be identified after troubleshooting, it is recommended to promptly record detailed information about the abnormality (including system composition, pH, temperature, dosage, storage conditions, etc.) and directly contact the technical team of Guoli Chemical for targeted diagnosis.
| Abnormal Phenomenon | Possible Cause | Suggested Action |
|---|---|---|
| Product turbidity or stratification | Storage temperature too low causing freezing, or prolonged high temperature exposure leading to degradation | Recommended storage temperature: 5℃～40℃; if deteriorated, replace with a new batch |
| Poor wetting effect | Insufficient dosage, or presence of components competing for the interface in the system | Increase dosage appropriately; check compatibility with other surfactants in the formulation |
| Abnormal increase in foam | Combination with other high-foaming surfactants | Check other components in the formulation; Polyether L-35 itself is a low-foaming product |
| Unstable emulsion/stratification | Oil phase type or ratio beyond its emulsification capacity | Adjust oil-water ratio, or consider combining with other emulsifiers |
| Skin or eye discomfort | Direct contact without protective equipment during operation | Skin contact: wash with soap and water; eye contact: rinse with water for at least 15 minutes, seek medical attention if discomfort persists |
To ensure optimal performance of Polyether L-35 in your system, pay attention to the following aspects: In paints and inks, add during the dilution stage to facilitate dynamic wetting; in cleaning agent formulations, combine with nonionic or anionic surfactants for synergistic effects; in metalworking fluids, test compatibility with rust inhibitors and extreme pressure additives; in textile dyeing and finishing, it is especially suitable for jet dyeing processes with low foam requirements.
