OPE-105 (octylphenol polyoxyethylene (10.5) ether) is a nonionic surfactant with relatively stable chemical properties. However, under improper storage conditions, it may absorb moisture, oxidize, or develop microbial contamination, affecting product performance. According to the official guidance in Section 4 of the Safety Data Sheet (SDS), this product should be stored in a dedicated warehouse, away from heat sources, sparks, open flames, and incompatible substances, avoiding drastic temperature fluctuations and direct sunlight.
The packaging container must be kept tightly closed and stored upright. It is recommended to use the original container or equivalent stainless steel or high-density polyethylene (HDPE) containers. The storage area should be equipped with spill containment pallets or secondary containment facilities, and should be provided with GHS-compliant hazard warning signs and safety operation instruction boards. Regularly inspect the integrity of containers and packaging. If damage is found, immediately transfer to a safe container and handle properly.
Regarding the shelf life, no specific shelf life data is provided in the product database. The SDS states: "The storage period should follow the manufacturer's recommendations, and a stability assessment should be performed before long-term storage." This means that the shelf life is closely related to storage conditions, packaging integrity, and other factors. It is generally recommended that users use the product as soon as possible after purchase. If long-term storage is required, it is advised to conduct small-scale performance verification (such as emulsifying power, cloud point, appearance, etc.) before use, and only put into production after confirming compliance.
| Storage Element | Specific Requirement |
|---|---|
| Temperature Range | Recommended 0°C to 30°C, avoid drastic temperature fluctuations |
| Environmental Requirement | Cool, dry, well-ventilated, avoid direct sunlight |
| Container Requirement | Keep tightly closed and upright; recommended stainless steel or HDPE material |
| Separation Requirement | Keep away from heat sources, open flames, oxidizers, strong acids and alkalis |
| Safety Facilities | Equip with spill containment pallets or secondary containment |
| Prohibited Items | Strictly separate from food and feed |
In practical industrial applications, it is recommended to follow the "first in, first out" inventory management principle to avoid long-term product accumulation. After each use, the container should be immediately sealed to prevent moisture from entering the air, which may cause product moisture absorption or surface skinning. If the product solidifies or precipitates at low temperatures, it is a normal physical phenomenon. It can be naturally warmed up in a 20°C–30°C environment and stirred evenly before use, without affecting performance.
