HEL-40 is a non-ionic surfactant produced by ethoxylation of natural hydrogenated castor oil. Proper storage is essential to maintain its comprehensive properties such as emulsification, solubilization, and dispersion. The core storage principle for the product is sealed, cool, dry, ventilated. It must be stored in the original sealed container, ensuring the lid is tightly closed and the container remains sealed to prevent moisture absorption or reaction with impurities in the air that may affect product quality.
Regarding the shelf life, the Guoli Chemical product database does not provide an exact shelf life in months for HEL-40, but it clearly emphasizes "Managing inventory on a first-in, first-out basis to avoid products exceeding their shelf life." According to general industry standards, for hydrogenated castor oil polyoxyethylene ether non-ionic surfactants stored under recommended conditions, the typical shelf life is 2 years (24 months) from the date of manufacture. It is recommended that users refer to the specific shelf life indicated on the product packaging label when purchasing and using, and prioritize earlier batches.
| Storage Element | Specific Requirements |
|---|---|
| Container Requirement | Original sealed container, ensure lid is tightly closed and container remains sealed |
| Storage Temperature | 5°C to 35°C (avoid freezing or overheating deterioration) |
| Environmental Condition | Cool, dry, well-ventilated, avoid direct sunlight |
| Substances to Keep Away | Keep away from heat sources, ignition sources, strong oxidizers, strong acids, strong bases, and other incompatible substances |
| Area Requirement | Laid with impermeable floor, equipped with spill collection facilities |
| Label Management | Keep container labels intact and legible to avoid misuse |
| Inventory Management | Follow First-In, First-Out (FIFO) principle to avoid products exceeding shelf life |
Before using HEL-40 that has been stored for a long time, it is recommended to observe whether the product appearance is normal—normal state should be light yellow paste to viscous liquid, without stratification, color change, or odor. If the product has been exposed to extreme temperatures (freezing or high heat), it is advisable to conduct a small sample test first to confirm no abnormalities in emulsification and solubilization performance before batch use, to avoid affecting formulation stability.
