Tween T-85 (Polyoxyethylene (20) sorbitan trioleate) is a nonionic surfactant with relatively stable chemical properties and is classified as a non-hazardous, non-flammable substance. To ensure long-term stability of product performance, the choice of storage environment is crucial. The product should be kept away from heat sources, sparks, open flames, and hot surfaces, and avoid contact with incompatible substances such as strong oxidizing agents, strong acids, and strong bases to prevent degradation or adverse reactions.
Regarding shelf life, the Guoli Chemical product database currently does not have explicit shelf life parameters for this product. According to general industry standards, the typical shelf life for Tween series nonionic surfactants under unopened and recommended storage conditions is generally 2 years from the date of manufacture. It is recommended that users refer to the production batch number and expiration date label on the product packaging. Products beyond their shelf life should be tested and verified for performance before use.
| Storage Factor | Specific Requirement |
|---|---|
| Environmental Requirement | Cool, dry, well-ventilated |
| Temperature Range | 5°C – 40°C (prevent freezing or thermal degradation) |
| Container Status | Keep tightly closed to prevent moisture and impurities from entering |
| Keep Away From | Heat sources, sparks, open flames, hot surfaces |
| Incompatible Substances | Strong oxidizing agents, strong acids, strong bases |
| Labeling Requirement | Clearly label containers to avoid misuse |
When opening and dispensing Tween T-85, minimize the time the container is left open to avoid long-term exposure to air, which may cause moisture absorption or contamination. Immediately close the container after use and use clean tools for dispensing to prevent cross-contamination. If the product shows signs of layering or cloudiness after long-term storage, it is recommended to stir evenly and take a sample for testing. Confirm that key performance indicators such as emulsification and solubilization meet the requirements before use.
