Emulsifier OS (fatty alcohol polyoxyethylene ether \/ secondary alkyl sodium sulfonate) and emulsifier MS-1 (octylphenol polyoxyethylene ether maleate) are both non-dangerous goods, but their storage requirements differ to some extent. Emulsifier OS, due to its skin and eye irritation properties (GHS classification category 2), requires stricter storage management, including storage in a dedicated warehouse equipped with spill containment materials; whereas MS-1 is a low-risk chemical with no hazard classification, thus its storage conditions are relatively more lenient.
The core storage principles common to both are: maintain a cool, dry, and well-ventilated environment, and containers must be kept sealed to prevent moisture and contamination. Both should be kept away from sources of heat and ignition, and avoid co-storage with incompatible substances (such as strong oxidizing agents). For MS-1, special attention must be paid to avoiding extreme temperatures and direct sunlight, as UV radiation and high temperatures may affect its chemical stability.
| Storage Requirement | Emulsifier OS | Emulsifier MS-1 |
|---|---|---|
| Storage Environment | Cool, dry, well-ventilated dedicated warehouse | Cool, dry, well-ventilated place |
| Temperature Requirement | Away from heat sources and ignition | Avoid extreme temperatures, away from heat sources |
| Light Requirement | No special requirement | Avoid direct sunlight |
| Container Sealing | Keep container sealed to prevent moisture and contamination | Keep container tightly closed |
| Incompatible Substances | Oxidizing agents, strong acids, etc.; do not co-store | Strong oxidizing agents |
| Warehouse Management | Dedicated warehouse equipped with spill containment materials (sand\/inert absorbents), follow the "first in, first out" principle | No special dedicated warehouse requirement |
| Transport Classification | Non-dangerous goods | Non-dangerous goods |
In practical warehouse management, it is recommended to store emulsifier OS on the bottom shelf of a dedicated chemical warehouse, away from doors, windows, and heating pipes to prevent temperature fluctuations. The warehouse should be equipped with spill-proof trays or dikes, and the floor should be treated to prevent leakage. Emulsifier MS-1 can be stored in a conventional chemical raw material warehouse but should also avoid open storage and direct sunlight.
For bulk purchasing users, it is recommended to manage inventory turnover following the "first in, first out" principle. Especially for emulsifier OS, it is advisable to perform a small-scale emulsification effectiveness test before use after long-term storage to ensure product performance has not changed. Both products should be stored in their original sealed containers, and should be resealed promptly after opening.
