OPP-10 Octylphenol Polyoxyethylene Ether Phosphate is an anionic phosphate surfactant, appearing as a pale yellow viscous liquid at room temperature. Due to the phosphate ester group in its molecular structure, the product has certain hygroscopicity, it is combustible when exposed to open flames and high heat, and thermal decomposition may release toxic phosphorus oxide gases. Therefore, proper storage is crucial for maintaining product performance and use safety.
This product is highly toxic to aquatic life with long-lasting effects. Strict measures must be taken to prevent leakage into sewers, surface water, and groundwater during storage and management. It should be stored separately from oxidizers, strong bases, and edible chemicals, and mixed storage must be avoided to prevent chemical reactions or contamination.
| Storage Requirements | Specific Conditions |
|---|---|
| Storage Environment | Cool, well-ventilated dedicated warehouse |
| Temperature Control | Warehouse temperature should not exceed 30°C |
| Container Status | Keep container sealed to prevent moisture absorption |
| Isolation Requirements | Keep away from fire and heat sources; store separately from oxidizers, strong bases, and edible chemicals |
| Management Requirements | Implement a two-person receiving and two-person storage system |
| Facility Requirements | Use explosion-proof lighting and ventilation equipment; prohibit the use of mechanical equipment and tools that may generate sparks |
| Emergency Preparedness | The storage area should be equipped with leak emergency treatment equipment and appropriate containment materials |
According to the Guoli Chemical database, there is no officially labeled shelf life data for OPP-10. In chemical industry practice, the shelf life of anionic phosphate surfactants usually depends on the compliance with storage conditions. Under strict adherence to the above storage conditions and with the original seal intact, it is generally recommended to use within 12 months to ensure optimal product performance.
If stored beyond the recommended period, check the product appearance before use (normal: pale yellow viscous liquid, no separation, no clumping, no unusual odor) and conduct small-scale tests to verify whether core properties such as emulsification and dispersion meet requirements. If the product shows significant color darkening, precipitation, or off-odor, discontinue use.
Follow the first-in-first-out principle when using the product to avoid long-term accumulation. Seal the container immediately after each use to prevent moisture absorption and contamination. For repackaging, use clean, dry containers and clearly label the product name and safety information. The product is available in 50kg plastic drums, 200kg plastic drums, and IBC totes. Choose an appropriate package size based on usage volume to reduce storage risks after opening.
