XPO-4 (glycerol polyoxyethylene ether oleate) is a nonionic surfactant, appearing as a light yellow to yellow transparent viscous liquid at room temperature. Proper storage is crucial for maintaining stable product performance and extending its service life. This product is non-flammable, with a flash point above 150°C, and is chemically stable under normal storage conditions.
Regarding shelf life, there is no official data for XPO-4 in the Guoli Chemical product database. According to the general industry experience for nonionic surfactant products, under strict adherence to storage conditions, it is generally recommended to use it within 2 years to ensure optimal performance. It is advised to follow the "first in, first out" inventory management principle and periodically check the product's appearance for any abnormal changes such as stratification, increased turbidity, or off-odors.
| Storage Element | Specific Requirement |
|---|---|
| Temperature Range | Recommended 5°C to 40°C; avoid freezing or prolonged exposure to high temperatures |
| Container Requirements | Keep sealed; use corrosion-resistant, leak-proof containers; set up dikes to contain spills |
| Environmental Conditions | Cool, dry, and well-ventilated warehouse |
| Segregation Requirements | Keep away from food, beverages, and animal feed |
| Incompatible Substances | Store separately from strong oxidizers, strong acids, and strong bases |
| Fire Prevention Measures | This product is a non-flammable liquid, but in case of fire, water spray, alcohol-resistant foam, dry powder, or carbon dioxide can be used for extinguishing |
After each use of XPO-4, immediately close the container tightly to minimize prolonged exposure to air, preventing moisture absorption or foreign matter contamination. If the product becomes more viscous or turbid at low temperatures, this is a normal physical change for nonionic surfactants. Allow the product to naturally return to a transparent state at room temperature (20°C–30°C) before use; do not apply direct heat. It is recommended to gently stir the product to ensure uniformity before use.
