Peregal O-80 (fatty alcohol polyoxyethylene ether) is a nonionic surfactant with a high degree of polymerization. At room temperature, it appears as white to slightly yellow flakes or waxy solids. The core principles for storage are moisture-proof, heat-proof, and sealed. Due to the presence of a large number of polyoxyethylene chains in its molecular structure, the product is hygroscopic. The packaging container must be kept airtight, and after opening, it should be immediately resealed to avoid absorbing moisture from the air, which could cause caking or deterioration.
Temperature directly affects the physical form of the product: high temperature environments (above 40°C) may cause the product to soften or even melt, while low temperatures (below 0°C) may cause it to harden. It is recommended to maintain the storage environment temperature stable between 0°C and 40°C, with relative humidity not exceeding 70%, and to avoid drastic temperature fluctuations to ensure product quality uniformity and ease of use. Additionally, the product should be kept away from strong oxidizers, strong acids, strong bases, and other incompatible substances, and should avoid direct sunlight and rain.
| Storage Factor | Specific Requirement |
|---|---|
| Location | Cool, dry, well-ventilated dedicated warehouse; floor with bunding or anti-leakage design |
| Temperature Range | 0°C – 40°C, avoid extreme temperatures and drastic temperature changes |
| Relative Humidity | Not exceeding 70% |
| Packaging Container | Keep original container sealed; compatible materials recommended: stainless steel, high-density polyethylene (HDPE) |
| Incompatible Substances | Keep away from strong oxidizers (peroxides, permanganates, etc.), strong acids, strong bases |
| Other Prohibitions | Keep away from food, beverages, and animal feed; avoid direct sunlight and rain |
| Management Principle | First In, First Out (FIFO), use within shelf life |
As of the current product database, there is no specific shelf life data for Peregal O-80. According to the general practice of the chemical industry for similar nonionic surfactants (fatty alcohol polyoxyethylene ethers), under strict compliance with the above storage conditions (sealed, moisture-proof, 0–40°C), the product shelf life is typically 1 to 2 years from the production date. Some high-quality batches may extend slightly under ideal storage conditions, but it is recommended to follow the "first in, first out" principle, giving priority to earlier batches.
