Emulsifier S-185/O-5 (fatty alcohol polyoxyethylene ether) is a nonionic surfactant, appearing as a white to pale yellow paste. To ensure long-term stability of product performance, control of the storage environment is crucial. The product should always be kept in the original sealed container. Once opened, it should be used as soon as possible, and any remaining material must be resealed to prevent moisture absorption and contamination.
Under recommended storage conditions (cool, dry, ventilated, 5–40°C), the product can maintain stable physicochemical properties. Exceeding the suggested temperature range may cause changes in product characteristics: high temperatures may accelerate oxidation or cause phase separation, while low temperatures may harden the paste, affecting ease of handling, but generally do not affect the intrinsic quality of the product.
| Storage Factor | Specific Requirement |
|---|---|
| Temperature Range | Recommended 5–40°C |
| Light | Avoid direct sunlight |
| Environmental Requirements | Cool, dry, well-ventilated warehouse |
| Container Condition | Keep sealed to prevent moisture and contamination |
| After Opening | Use as soon as possible; reseal remaining material |
| Packaging | Sealed packaging; recommended to use corrosion-resistant containers such as stainless steel or plastic-lined drums |
| Away from Substances | Strong oxidizers, strong acids, strong bases, and other incompatible materials |
| Fire Source Management | Keep away from heat sources, sparks, and open flames (product is not flammable, flash point >150°C, but general chemical handling procedures should still be followed) |
In actual use, if the product becomes hard or turbid due to low-temperature storage, it can be transferred to a warm environment to naturally warm up (direct heating is not recommended). Once it returns to room temperature, stir evenly and it can be used normally. Product performance is generally not irreversibly affected by short-term temperature fluctuations.
