Hydrogenated castor oil polyoxyethylene ether HEL-40 is a nonionic surfactant produced by ethoxylation of natural hydrogenated castor oil. The product appears as a light yellow paste to viscous liquid. Proper storage conditions are essential for maintaining its comprehensive performance in emulsification, solubilization, wetting, and dispersion. Improper storage may lead to issues such as product stratification, discoloration, performance degradation, or microbial growth.
This product is not a hazardous substance and does not require mandatory hazard labeling under GHS classification, but standard chemical storage management principles should still be followed. The storage area should have an impermeable floor and be equipped with spill containment facilities to prevent environmental impact from accidental leaks. Additionally, it should be stored separately from strong acids, strong bases, and other incompatible substances to avoid cross-contamination or adverse reactions.
For inventory management, it is recommended to follow the "first-in, first-out" principle to ensure the product is used within its shelf life. Keep container labels intact and legible to avoid misuse due to unclear identification. If the product solidifies or precipitates at low temperatures, it can be slowly warmed within the recommended temperature range and stirred evenly before use, which generally does not affect product performance.
| Item | Requirement |
|---|---|
| Container Requirement | Original sealed container, tightly capped and kept sealed |
| Storage Temperature | 5°C to 35°C (avoid freezing or overheating deterioration) |
| Environmental Requirement | Cool, dry, well-ventilated, avoid direct sunlight |
| Substances to Keep Away From | Heat sources, ignition sources, strong oxidizers, strong acids, strong bases |
| Floor Protection | Impermeable floor, equipped with spill containment facilities |
| Label Management | Keep labels intact and legible to avoid misuse |
| Inventory Management | First-in, first-out principle, avoid exceeding shelf life |
In application fields such as cosmetics and personal care, textile auxiliaries, metalworking fluids, hard surface cleaners, and pesticide formulations, inspect the product's appearance and properties before use. If slight stratification or viscosity fluctuations due to temperature changes occur after long-term storage, the product can be restored by stirring thoroughly within the recommended temperature range, and its core properties such as emulsification and solubilization are generally unaffected.
For bulk procurement customers requiring long-term storage, it is recommended to confirm the specific batch's shelf life with Guoli Chemical and plan procurement volumes based on usage pace to avoid prolonged product accumulation.
