Tristyrylphenol ethoxylate 600-2 and 600-1 series are nonionic surfactants with stable chemical properties. Under conventional storage conditions, they are resistant to acids, bases, hard water, and various metal salts, and are not prone to hydrolysis or oxidative degradation. At room temperature, the product is a pale yellow viscous liquid to waxy solid with extremely low water sensitivity. It is not easily hygroscopic or caking in humid environments, making storage convenient.
The key points for storage are: keep the container completely sealed to prevent moisture and impurities, store in a cool, dry, and well-ventilated environment, away from direct sunlight. It is recommended to use a sealed container with a corrosion-resistant inner lining to avoid prolonged direct contact with metals. The storage area floor should be slip-resistant, chemically resistant, and equipped with spill containment facilities.
Under low-temperature conditions, the product may solidify or increase in viscosity, which is a normal physical change and does not affect the intrinsic quality of the product. Before use, simply warm it up slightly at room temperature and stir evenly to restore fluidity. However, repeated freezing and thawing should be avoided. It is recommended to control the storage temperature between 5–35°C.
| Storage Element | Specific Requirements |
|---|---|
| Temperature Range | 5–35°C, avoid repeated freezing and thawing |
| Environmental Requirements | Cool, dry, well-ventilated, avoid direct sunlight |
| Container Requirements | Clean, dry, dedicated iron drums or high-density polyethylene drums with corrosion-resistant inner lining |
| Sealing Status | Keep container completely sealed to prevent moisture and impurities |
| Materials to Keep Away | Ignition sources, heat sources, sparks, open flames, strong oxidizers, and other incompatible substances |
| Warehouse Management | Floor slip-resistant and corrosion-resistant, equipped with spill containment facilities, implement "first-in, first-out" principle |
| Low-Temperature Handling | Solidification or increased viscosity is normal; restore by warming at room temperature and stirring |
The specific shelf life of this product is not indicated in the Guoli Chemical product database. Given the stable chemical properties of this product, under strict compliance with the above storage conditions, the recommended usage period for nonionic surfactant products is generally 1–2 years (from the production date). It is recommended to confirm the batch production date and expiration date information with the Guoli Chemical sales or technical department, and strictly follow the "first-in, first-out" inventory management principle.
