The PEG-150 distearate series products (including the powder form thickener 6000DS and the liquid form thickener 638) are nonionic surfactants with stable chemical properties and are not flammable. However, environmental conditions must be controlled during storage to ensure product performance is not affected. The powder product (6000DS) should be kept away from moisture to prevent caking; the liquid product (thickener 638) should avoid drastic temperature fluctuations to prevent phase separation or a decrease in transparency.
The storage environment should be away from moisture, rain, and direct sunlight, and the warehouse must maintain good ventilation. Product packaging containers should always be kept sealed and placed on pallets at an appropriate distance from the ground to prevent ground moisture ingress. If not fully used after opening bags or drums, they should be immediately and securely resealed to prevent the product from absorbing moisture or being contaminated.
| Storage Parameter | Requirement |
|---|---|
| Storage Environment | Cool, dry, well-ventilated warehouse, away from moisture, rain, and direct sunlight |
| Recommended Temperature | Not exceeding 45℃ |
| Recommended Humidity | Relative humidity below 70% |
| Packaging Management | Keep original containers sealed, place on pallets, reseal after opening bags/drums |
| Incompatible Substances | Keep away from strong acids, strong bases, and active oxidizing agents |
| Shelf Life | Effective storage period of two years for unopened products from the date of manufacture |
| Transportation Handling | Handle as general chemical products, load and unload gently to prevent packaging damage and dust emission |
It is recommended to establish a "first-in, first-out" inventory management principle to avoid long-term accumulation. For powder thickener 6000DS, regularly check for caking; for liquid thickener 638, observe for any layering or color change. If the products are properly stored under recommended conditions, stable thickening efficiency and compatibility performance can be maintained within the two-year shelf life.
