Perfume O-10 (fatty alcohol polyoxyethylene ether-10, AEO-10) is a nonionic surfactant with stable chemical properties, resistant to acids, alkalis, and hard water. However, proper storage is crucial to maintain its performance and extend its service life. This product is a white to light yellow paste at room temperature (melting point approximately 25°C), so special attention should be paid to storage temperature to avoid melting due to high heat or freezing at low temperatures, which may cause product stratification or cloudiness.
According to safety technical data provided by Guoli Chemical, this product is recommended to be stored in a cool, dry, well-ventilated dedicated warehouse inside sealed containers, away from fire sources, heat sources, and incompatible substances such as strong oxidizers, strong acids, and strong alkalis. Direct sunlight and prolonged UV exposure should be strictly avoided as they accelerate product aging. Additionally, the storage area should be equipped with spill emergency response equipment, and the floor should be treated for anti-seepage.
Regarding the shelf life, the Guoli Chemical product database does not specify a fixed shelf life. However, according to industry practice for nonionic surfactants, under strict compliance with the above storage conditions (10°C~35°C, sealed, light-proof), the shelf life of Perfume O-10 is generally 12 to 24 months. It is recommended that users follow the "first in, first out" principle for inventory management and periodically inspect the product for abnormal changes in appearance and performance indicators.
| Parameter | Specification or Requirement |
|---|---|
| Recommended Storage Temperature | 10°C to 35°C |

| Environmental Requirement | Cool, dry, well-ventilated |
| Light Requirement | Avoid direct sunlight and prolonged UV exposure |
| Container Requirement | Keep sealed; original container preferred |
| Substances to Keep Away | Strong oxidizers, strong acids, strong alkalis |
| Segregation Requirement | Store strictly separately from food, beverages, feed, etc. |
| Appearance (Normal State) | White to light yellow paste |
If the product has been stored for a long period, before first opening the drum for use, it is recommended to perform a visual inspection and simple performance verification (e.g., check if a 1% aqueous solution is clear and whether the pH is within the normal range of 5.0-7.0). If the product has exceeded the recommended shelf life by a significant margin, even if no obvious changes in appearance are observed, small-scale tests should be conducted before use in critical formulations (e.g., cosmetics, pesticide preparations) to confirm that core properties such as emulsifying power and wetting ability have not deteriorated, thereby avoiding impact on final product quality.
