Question

What are the storage conditions for Emulsifier A-110, Oleic Acid Polyoxyethylene Ester, OEO-110?

Answer

Emulsifier A-110 should be stored in a cool, dry, and well-ventilated warehouse in a sealed container. The recommended temperature is 5°C to 35°C. It is a non-hazardous substance with relatively flexible storage conditions.

Detailed Explanation

Emulsifier A-110 (Oleic Acid Polyoxyethylene Ester · OEO-110) is a nonionic surfactant with stable chemical properties. It is not classified as a hazardous substance, so special storage controls are not required. However, its appearance and performance are significantly affected by temperature: temperatures that are too low (below 5°C) may cause the product to solidify or become viscous, affecting ease of use; temperatures that are too high (above 35°C) may accelerate oxidation, leading to darkening of color or reduced performance.

During storage, it is essential to keep the container sealed to prevent moisture absorption or contamination by dust and impurities. Since this product has some hygroscopicity, prolonged exposure to humid air may increase its moisture content, thereby affecting its effectiveness in formulations. Additionally, contact with strong oxidizing agents should be strictly avoided to prevent chemical reactions that could degrade the product.

It is recommended to set up pallets or containment berms in the storage area to effectively contain and prevent the spread of accidental spills. At the same time, general principles of chemical storage should be followed, keeping it away from food and feed and implementing segregated storage management.

Application Recommendations

In actual use, if the product solidifies or becomes viscous due to low temperature, do not heat directly with an open flame. It is recommended to place the sealed container in a warm environment for slow temperature recovery, or use a warm water bath (≤35°C) for gentle heating with proper stirring. Once it returns to a fluid state, it can be used normally without affecting product performance.

After each use, promptly seal the container to minimize contact with air. For long-term bulk storage, it is recommended to follow the "first in, first out" principle and prioritize using earlier batches within the shelf life.

Precautions

  • Although this product is non-hazardous, it should still be kept away from children and unauthorized personnel, and managed in dedicated storage areas.
  • If a spill occurs, small spills can be treated with inert absorbent materials such as sand, vermiculite, etc.; large spills should be contained to prevent entry into drains or water bodies.
  • During transportation, keep the container sealed, avoid transporting with strong oxidizing agents, and protect from sunlight and rain.
  • Do not dispose of waste by pouring into drains or the environment; it should be handed over to qualified waste disposal agencies for compliant treatment.
