Diethanolamine, often abbreviated as DEA or DEOA, is an organic compound. It is used as a surfactant and a corrosion inhibitor. It is used to remove hydrogen sulfide and carbon dioxide from natural gas.Diethanolamine is widely used in the preparation of diethanolamides and diethanolamine salts of long-chain fatty acids. Its amphoteric nature—meaning it can act as both an acid and a base—makes it versatile in various chemical reactions.

Industrial Uses

1. Paints, Coatings & Adhesives

Antimicrobial Agent: Diethanolamine can be added to paint formulations to provide antimicrobial properties, helping to prevent the growth of mold and mildew on painted surfaces.
Crosslinking Agent: Due to its bifunctional nature, DEA can act as a crosslinking agent, contributing to the formation of a three-dimensional network in the polymer matrix, which improves the durability and chemical resistance of the coating.

2. Animal Healthcare

Nutritional Supplement: Diethanolamine may be included in animal feed formulations as a nutritional supplement, supporting overall health and growth in livestock.
Topical Treatments: It can be used in topical treatments for animals, enhancing the absorption of active ingredients in skin ointments and creams.

3. Construction

Flexible Sealant: Diethanolamine is utilized in flexible sealants for construction applications, ensuring good adhesion and flexibility for joints and seams.
Concrete Hardener: It can be incorporated into concrete hardeners to enhance the strength and durability of concrete structures.

4. Water Treatment

Corrosion & Scale Inhibitors : As a corrosion inhibitor, DEA is utilized in boiler water treatment and cooling systems. It forms protective films on metal surfaces, safeguarding equipment from corrosive damage caused by dissolved oxygen and acidic substances in water. This application is vital in maintaining the integrity of boilers, condensers, and pipelines.

5. Personal Care

Hair Styling Products: Diethanolamine is often included in hair gels and styling products for its ability to provide hold and improve texture.
Facial Cleansers: It can be used in facial cleansers to enhance foaming properties, making the product more effective at removing impurities.

6. Polymers & Resins

Curing Agents & Crosslinkers : Diethanolamine is used as a curing agent in the production of epoxy resins, facilitating the hardening process and improving mechanical properties.
Plasticizers & Flexibility Enhancers: DEA serves as a reactive plasticizer in starch-based polymer blends, such as those with polypropylene (PP), enhancing interfacial compatibility and mechanical properties like tensile strength and modulus.
