Is DEA diethanolamine (CAS 111-42-2) toxic?

DEA Diethanolamine Chemical Properties

Diethanolamine (DEA) is a colorless, transparent liquid that is alkaline at room temperature. It is highly soluble in water, ethanol, and other solvents, with a melting point of 28°C and a boiling point of 271°C. DEA readily absorbs carbon dioxide from the air to form stable diacetic acid amine. It exhibits alkalinity and hydrophilicity, serving as a crucial surfactant and solvent. In laboratories, it is commonly used to prepare organic compounds such as esters, amides, and ethers. It also finds extensive applications in pharmaceuticals, dyes, coatings, rubber, resins, and other industries.

DEA Diethanolamine Physical Properties

Diethanolamine has a density of 1.09 g/cm³, falling within the density range of oils. However, its molecular structure is complex and lacks the hydrocarbon chain structure and chemical properties typical of conventional oils. Therefore, it is not classified as an oil.

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.

Is DEA diethanolamine (CAS 111-42-2) toxic?

Acute animal studies have shown that dermal exposure to diethanolamine (CAS 111-42-2) may burn skin, and eye contact with the chemical may impair vision.

How is diethanolamine (CAS 111-42-2) stored safely?

To ensure the safe use of diethanolamine (CAS 111-42-2), the following recommendations are provided:

Ethanolamine should be stored in a cool, dry, well-ventilated place, away from fire and heat sources, and away from direct sunlight.

During handling, personal protective equipment such as respirators, chemical protective goggles, and protective clothing should be worn to prevent direct skin contact or vapor inhalation.

While using ethanolamine, monitor your physical condition. If any discomfort occurs, seek medical attention immediately.
