Pingpengjia O-20 (C16-18 fatty alcohol polyoxyethylene (20) ether) is a nonionic surfactant, appearing as a milky white to light yellow waxy solid or paste at room temperature. Its physicochemical properties are relatively stable, non-flammable, and non-explosive, but proper storage is crucial for maintaining product performance. Improper storage may lead to moisture absorption, caking, color deepening, or reduced surface activity.
This product should be stored in a dedicated warehouse with the container kept tightly closed, using original or compatible material containers (e.g., polyethylene, stainless steel). The storage area must be equipped with spill containment facilities, and the floor should be impermeable. Keep away from incompatible substances such as strong oxidizers, strong acids, and strong alkalis, and avoid heat, moisture, and direct sunlight.
Regarding shelf life: There is no official shelf life mark for Pingpengjia O-20 in the Guoli Chemical product database. According to common experience in the nonionic surfactant industry, under strict compliance with the above storage conditions, the typical shelf life of unopened Pingpengjia O-20 is 1–2 years. It is recommended to follow the "first in, first out" principle, use promptly after opening, and regularly check for changes in appearance and performance.
| Storage Element | Specific Requirement |
|---|---|
| Temperature | Cool environment, avoid high temperature and heat |
| Humidity | Dry environment, strictly prevent moisture |
| Ventilation | Good ventilation |
| Lighting | Avoid direct sunlight |
| Container | Keep tightly closed, original or compatible material container |
| Isolation Requirements | Keep away from strong oxidizers, strong acids, strong alkalis |
| Safety Facilities | Spill containment facilities, impermeable floor treatment |
Immediately reseal the container after each use to prevent the product from absorbing moisture from the air, which may cause caking or deterioration. If the product shows obvious color deepening (e.g., turning dark brown), off-odor, or delamination, it is recommended to stop using and test a sample before making a judgment.
