How should DEA diethanolamine (CAS 111-42-2) be stored?

diethanolamine (CAS 111-42-2) Uses

• As an emulsifier: DEA can mix water and oil together, therefore it is widely used in the coatings, plastics, and ink industries.
• Improving product flowability: DEA acts as a delayed emulsifier and wetting agent, improving the flowability and gloss of products.
• Adjusting pH: Diethanolamine is an organic base that can be used to adjust the pH of solutions, commonly used in cosmetics and personal care products.
• Inhibiting bacterial and fungal growth: Diethanolamine has bactericidal and disinfectant properties, preventing the growth and reproduction of microorganisms, and is therefore commonly used in soaps, detergents, pesticides, and other related products.

How should diethanolamine (DEA) be stored?

The following safety measures must be followed when storing diethanolamine (DEA):

• Container Selection: Use chemically resistant, airtight containers (such as high-density polyethylene or stainless steel) to ensure sealing and prevent moisture absorption or evaporation.
• Environmental Conditions: Store in a cool (recommended temperature <30°C), dry, well-ventilated dedicated area, avoiding direct sunlight or high temperatures to prevent decomposition or polymerization.
• Isolation Requirements: Keep away from oxidizers (such as peroxides), strong acids, and reactive metals (such as sodium) to prevent violent reactions. The storage area should be equipped with spill-proof trays.
• Handling Protection: Wear chemical protective gloves, goggles, and a respirator when handling. Avoid skin or eye contact.
• Emergency Preparedness: Have absorbent materials (such as sand or diatomaceous earth) and neutralizing agents (such as dilute acetic acid) available. In case of leakage, immediately isolate and handle the situation.
• Labeling and Management: Containers must be clearly labeled with their name and hazard warnings (such as "corrosive"). Regularly check the seals and label integrity. For long-term storage, nitrogen purging is recommended to reduce the risk of oxidation. Following these measures can effectively reduce fire, health, and environmental risks, ensuring compliance and safety.
