OP-30 should be stored in a cool, dry, and well-ventilated dedicated warehouse, keeping the container tightly sealed, away from fire sources, heat sources, and direct sunlight, and avoiding high temperatures or freezing.

Detailed Description

OP-30 Octylphenol Ethoxylate (CAS No.: 9036-19-5) appears as a white to light yellow waxy solid or paste at room temperature. Proper storage conditions are crucial for maintaining the product's chemical stability and performance. This product is a non-ionic surfactant with relatively stable chemical properties, but unsuitable storage environments may still cause moisture absorption, discoloration, stratification, or reduced efficacy.

Special attention should be paid to temperature control during storage. The product technical specification recommends keeping the storage temperature within a specified range, avoiding both high temperatures (which may accelerate oxidation, cause darkening, or degrade the product) and freezing (which may disrupt product uniformity and even cause container rupture). Additionally, this product is hygroscopic; ensure the container is always tightly sealed, and reseal immediately after opening to prevent moisture absorption and caking.

Storage Conditions at a Glance

Temperature ControlAvoid high temperatures or freezing; keep within the range recommended by the product technical specification
Light RequirementsAway from direct sunlight
Fire/Heat SourcesAway from fire and heat sources
Container SealingKeep container tightly sealed; reseal immediately after opening
Isolation StorageStore strictly separately from food, beverages, feed, and strong oxidizers
Spill ContainmentEquip with spill containment trays or dikes; use impermeable flooring materials

Application Recommendations

In practical warehouse management, it is recommended to store OP-30 indoors at a temperature of 10–30°C with a relative humidity not exceeding 60%. It can be packaged in original sealed drums or fiber drums lined with plastic bags. If the product solidifies or separates due to low temperature, slowly warm it in a warm environment and stir evenly before use; do not directly heat with open flames or steam.

Follow the first-in, first-out (FIFO) principle, prioritizing earlier batches within the shelf life. Regularly check the integrity and sealing of packaging; if leakage or damage is found, immediately transfer to an intact container.

Precautions

  • Do not store together with strong oxidizers (e.g., concentrated nitric acid, peroxides) to avoid unsafe reactions.
  • Do not discharge leaks into sewers or surface waters; this product is harmful to aquatic life (H402).
  • Prominent safety signs should be placed in the storage area; operators must be familiar with the SDS of this product.
  • If a leak occurs, immediately contain with inert absorbent materials (e.g., sand, diatomaceous earth), collect, and dispose of properly in sealed waste containers.
