OPP-10 should be stored sealed in a cool, well-ventilated place with warehouse temperature not exceeding 30°C, away from fire sources and oxidizers; there is no official shelf life data, and it is recommended to use within 12 months under original sealed conditions.

Detailed Description

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 Conditions

Storage RequirementsSpecific Conditions
Storage EnvironmentCool, well-ventilated dedicated warehouse
Temperature ControlWarehouse temperature should not exceed 30°C
Container StatusKeep container sealed to prevent moisture absorption
Isolation RequirementsKeep away from fire and heat sources; store separately from oxidizers, strong bases, and edible chemicals
Management RequirementsImplement a two-person receiving and two-person storage system
Facility RequirementsUse explosion-proof lighting and ventilation equipment; prohibit the use of mechanical equipment and tools that may generate sparks
Emergency PreparednessThe storage area should be equipped with leak emergency treatment equipment and appropriate containment materials

Shelf Life Explanation

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.

Application Recommendations

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.

Precautions

  • Wear permeation-resistant work clothing, chemical-resistant gloves (e.g., nitrile rubber gloves), and chemical safety goggles during operation. Avoid skin and eye contact.
  • No smoking in the workplace; use explosion-proof electrical equipment.
  • If leakage occurs, immediately cut off ignition sources, collect with non-combustible absorbent materials (e.g., sand), and seal for disposal. Prevent entry into waterways.
  • Dispose of waste products in accordance with hazardous chemical regulations through qualified units; do not discharge arbitrarily.
