Castor Oil Polyoxyethylene Ether EL-10 (PEG-10 Castor Oil) is classified as a non-hazardous, non-flammable liquid with relatively stable chemical properties. However, to ensure that the product performance does not deteriorate, storage conditions must still be strictly controlled. This product should be stored in a cool (recommended 0°C–40°C), dry, and well-ventilated warehouse, away from heat sources, ignition sources, and incompatible substances (such as strong oxidizers and strong acids), to prevent product decomposition, discoloration, or stratification due to high temperature or contact with incompatible materials.
Regarding the container, it must be kept tightly closed to prevent moisture absorption and external contamination. Since this product is a non-ionic surfactant, prolonged exposure to humid air may cause water absorption, affecting its emulsifying performance and usage effects. At the same time, avoid direct sunlight, as ultraviolet light and high temperature may accelerate oxidation and deterioration.
Regarding the shelf life, the product database provided this time does not contain official shelf life data for this product. Under normal circumstances, for non-ionic surfactants of the castor oil polyoxyethylene ether type, when stored in sealed and standard conditions, it is recommended to use within 1-2 years from the date of manufacture to ensure optimal emulsifying performance and product quality. After the recommended storage period, it is advisable to sample and test key indicators such as appearance and emulsifying performance before use, and only use if they meet requirements.

To ensure optimal performance during use, it is recommended to follow the "First In, First Out" inventory management principle. After opening a drum for sampling, reseal the container as soon as possible to minimize air exposure. If noticeable stratification, turbidity, discoloration, or odor is observed, it may indicate deterioration, and the product should not be used further.
For large-scale tank storage, regularly check the sealing of the tank and whether there is water accumulation at the bottom. If necessary, install breather valves and drying devices to control moisture ingress. During low-temperature storage in winter, note that an increase in viscosity is normal. The product can be used normally after the ambient temperature rises, and do not heat directly with an open flame.
