Fatty amine polyoxyethylene ether AC-1860 (octadecylamine polyoxyethylene ether (60)) is a non-ionic surfactant with stable chemical properties. However, to ensure product quality and performance, control of the storage environment is crucial. The melting point of this product is approximately 35~45°C. At room temperature, it usually appears as a light yellow to yellowish-brown solid or paste, so changes in storage temperature directly affect its physical state and convenience of use.
From a chemical stability perspective, AC-1860 is resistant to acids, alkalis, and hard water, and is not prone to hydrolysis or failure under normal storage conditions. However, prolonged exposure to high temperatures, humidity, or ultraviolet light may still lead to darkening of color, a decrease in active ingredient content, or weakened emulsifying and dispersing performance. Therefore, strict adherence to storage specifications is key to extending its service life.
According to the Safety Data Sheet (SDS), the storage of AC-1860 must meet the following specific requirements:
| Item | Requirement |
|---|---|
| Storage Environment | Cool, dry, well-ventilated dedicated warehouse or storage tank |
| Temperature Range | 10°C – 35°C (avoid freezing and prolonged high temperature exposure) |
| Container Sealing | Keep sealed to prevent moisture absorption and entry of foreign matter |
| Keep Away from Ignition Sources | Keep away from heat, sparks, and open flames |
| Incompatible Materials | Store separately from strong oxidizers and strong acids to avoid contact |
| Spill Prevention Facilities | Equip storage area with spill containment pallets and emergency response equipment |
| Recommended Packaging Material | Stainless steel, polyethylene, or plastic-lined iron drums (copper and aluminum containers are strictly prohibited) |
| Packaging Specifications | 50kg plastic drum, 200kg plastic drum, or IBC tote (source: Guoli Chemical product database) |
Currently, the Guoli Chemical product database does not provide explicit shelf life (validity period) data for AC-1860. Based on general experience with similar non-ionic surfactants, under strict adherence to the above storage conditions and with the container intact and sealed, the product can typically maintain acceptable performance for 1–2 years after production.
It is recommended that users: ① Check the validity period indicated on the product outer packaging label or the Certificate of Analysis (COA); ② Contact the sales or technical department of Hai'an Guoli Chemical Co., Ltd. directly to obtain batch-specific validity periods and re-inspection recommendations; ③ Periodically sample and test the product's appearance, pH value, and active ingredient content to confirm its suitability for production.
