Tween T-20 coconut fatty acid (Polyoxyethylene (20) sorbitan monococonut fatty acid ester) is chemically stable under normal storage conditions. However, to ensure product quality and extend shelf life, the following storage guidelines must be followed. When properly stored under recommended conditions, the product has a shelf life of 24 months from the date of manufacture. After opening, it should be resealed as soon as possible to prevent moisture absorption and contamination.
The product should be kept away from incompatible substances such as strong oxidizing agents, strong acids, and strong bases to avoid chemical reactions that may cause product deterioration. The storage area is recommended to have impermeable flooring and be equipped with appropriate spill containment facilities to handle accidental leaks.
| Storage Requirement | Specific Description |
|---|---|
| Container Status | Keep tightly sealed; reseal immediately after opening |
| Storage Temperature | 5°C to 35°C (recommended), avoid extreme temperatures |
| Environmental Conditions | Cool, dry, well-ventilated, away from direct sunlight |
| Incompatible Substances | Strong oxidizing agents, strong acids, strong bases, and other incompatible materials |
| Floor Protection | Impermeable flooring with spill containment facilities |
| Shelf Life | 24 months from date of manufacture (when stored properly under recommended conditions) |
As a nonionic surfactant, Tween T-20 coconut fatty acid has certain hygroscopicity. Prolonged exposure to humid air may increase the moisture content of the product, thereby affecting its dosing accuracy in fine formulations such as cosmetics, pharmaceuticals, and foods. Therefore, it is recommended to seal the container immediately after each use and to operate in a dry environment as much as possible.
If the product becomes turbid or separates when stored at low temperatures, this is a normal physical phenomenon for nonionic surfactants. Typically, allowing it to return to room temperature (15°C~25°C) and stirring gently until uniform will restore normal use without affecting product performance.
