Fatty amine polyoxyethylene ether AC-1860 (CAS No.: 26635-92-7) is stable under normal use conditions. However, due to its wide range of applications (textiles, pesticides, metalworking, daily chemicals, etc.), actual working conditions vary greatly, and occasionally problems such as poor emulsification, unsatisfactory dispersion effects, or compatibility issues with other components in the formulation may occur. In such cases, it is recommended to first self-check from the following aspects: whether the addition sequence is correct, whether the pH value of the system is within the optimal working range of AC-1860 (its cationic properties can be enhanced under neutral to acidic conditions), whether the water hardness is too high, and whether the storage temperature exceeds the recommended range of 10°C–35°C.
If the problem persists after self-checking, the most direct and effective approach is to contact the Guoli Chemical technical team. You can provide the product batch number, application formulation summary, and description of abnormal phenomena. The technical staff will analyze the root cause of the problem based on key indicators such as the product's HLB value (approximately 18), cloud point (>100°C), and critical micelle concentration (approximately 0.001 g/L), and provide suggestions for formulation adjustments or process optimization. In emergency situations (e.g., massive leakage or personal injury from exposure), please prioritize following the emergency treatment measures in Section 5 of the SDS.
Official channels for obtaining technical support: directly contact the after-sales service or technical department of Hai'an County Guoli Chemical Co., Ltd. to obtain the latest version of the Safety Data Sheet (SDS) and Product Technical Data Sheet (TDS). The safety instructions in the database explicitly state: "For matters not covered, please refer to the product Safety Data Sheet (SDS) or contact the manufacturer for the latest version." It is recommended that users keep the SDS with the company's contact information at the use site for immediate response.
| Problem type | Possible cause | Recommended action |
|---|---|---|
| Poor emulsification effect | Insufficient dosage, pH deviation, high water hardness | Gradually increase the dosage; adjust system pH to acidic to activate cationic properties; use soft water or add chelating agents |
| Product stratification\/precipitation | Solidification due to low storage temperature (melting point approx. 35–45°C) | Return to room temperature and gently heat with stirring to homogenize, avoid local overheating |
| Incompatibility with anionic components | Improper ratio of anionic\/nonionic surfactant blending | Adjust the anionic-nonionic ratio, or utilize its cationic properties under acidic conditions to optimize compatibility |
| Skin irritation from contact | Direct contact without protective equipment | Immediately remove contaminated clothing, rinse with running water and soap for at least 15 minutes; seek medical attention if irritation persists |
| Eye irritation from contact | Splashes or failure to wear goggles | Evert eyelids, rinse thoroughly with plenty of running water or saline for at least 15 minutes while rotating the eyeballs; seek immediate medical attention |
| Product leakage | Damaged packaging or improper handling | For small leaks, absorb with sand, vermiculite, and collect in closed containers; for large leaks, construct dikes, transfer with explosion-proof pump; do not discharge into waterways |
To avoid problems during use, it is recommended to conduct small-scale tests before developing new formulations or switching processes. AC-1860 is a nonionic surfactant that exhibits cationic properties in acidic media. This unique characteristic can significantly enhance its emulsification and corrosion inhibition capabilities in specific systems. It is recommended to fully utilize this property to optimize formulation design. Recommended storage temperature is 10°C–35°C, avoiding freezing and prolonged high-temperature exposure; packaging containers should be made of stainless steel, polyethylene, or plastic-lined iron drums, avoiding copper or aluminum containers.
