Potential Health Effects

Eye:Contact N,N-Dimethylethanolamine with eyes may cause severe irritation, and possible eye burns. Lachrymator (substance which increases the flow of tears). 
Skin: it may cause severe irritation and possible burns, may be harmful if absorbed through the skin. 
Ingestion: if ingest it , may cause burns to the digestive tract, may be harmful if swallowed. 
Inhalation: N,N-Dimethylethanolamine may cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. 
Chronic: Possible risk of harm to the unborn child. 

First Aid Measures

Eyes:Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed. Extensive irrigation with water is required (at least 30 minutes). 
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes. 
Ingestion: Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. 
Inhalation:Get medical aid immediately. Remove from exposure and move to fresh airimmediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. 

Fire Fighting Measures

As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. Containers may explode in the heat of a fire. Flammable liquid and vapor. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. 

In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Do NOT get water inside containers. For large fires, use water spray, fog or alcohol-resistant foam. Cool containers with flooding quantities of water until well after fire is out. 

Handling and Storage 

Wash thoroughly after handlingN,N-Dimethylethanolamine (CAS NO:108-01-0) .Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Do not ingest or inhale. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Keep N,N-Dimethylethanolamineaway from heat, sparks and flame.

Store N,N-Dimethylethanolamine in a tightly closed container. Store it in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. Store protected from light.

The uses of N,N-Dimethylethanolamine

N,N-Dimethylethanolamine is a kind of clear to pale yellow liquids with Molecular Formula: C4H11NO and Molecular Weight:89.14. It is miscible with water and soluble in alcohols, diethyl ether. N,N-Dimethylethanolamine forms azeotrope with water. It is related to choline and is a biochemical precursor to the neurotransmitter acetylcholine. It is reported to have nootropic effects, although research on this chemical has found both positive and negative potential results. The CAS Registry Number is 108-01-0.

N,N-Dimethylethanolamine is produced by interaction of excess of dimethylamine with ethylene oxide. It is stable, flammable, and incompatible with oxidizing agents, copper, copper alloys, zinc, acids, galvanised iron. Hygroscopic.

N,N-Dimethylethanolamine(CAS NO: 108-01-0) is applied as corrosion inhibitor, epoxy resins hardener, carbamide resins stabilizer, lubrucant for acetate fibers; It may be used to the synthesis of dyestuffs, textile auxiliaries, ion-exchange and alkyd resins, emulsifiers and bioactive compounds, or as a raw material in preparation of aminoacrylates; It is also used in pharmaceuticals synthesis (dimedrol, pentocain, procaine); It can be used to produce complexing agents ), paint removers; In  pharmaceutics (Deanol) as an antidepressive or antidyskinesia agent to treat movement disorders, as a curing agent for polyurethanes and epoxy resins.

After showing you the summary usage of N,N-Dimethylethanolamine, now let me tell the details.

N,N-Dimethylethanolamine is used in the preparation of water-reducible coating formulations. Government regulations covering the amount of organic solvent allowable in the air have spurred a search for emission control procedures. One of the most promising is the replacement of the organic solvent by water. The resins used in coating formulations are not water soluble, but can be made so by reacting them with the amine. 

N,N-Dimethylethanolamine can be used to control corrosion in boiler water condensate return lines. The dimethylethanolamine boils with the steam and is carried with it throughout the system. When the steam condenses, the dimethylethanolamine neutralizes any acidic components present in the condensate, thereby controlling the corrosion which would otherwise occur. For more applications, see other applications. 

N,N-Dimethylethanolamine is one of the raw materials used to make dimethylaminoethyl methacrylate. Polymers produced from the methacrylate are useful as antistatic agents, soil conditioners, electrically conducting materials, paper auxiliaries, and flocculating agents.

The use of N,N-Dimethylethanolamine has been studied in other applications. Some of these areas are: 
1.Preparation of resins which can be used to increase the dry strength or wet strength of paper. 
2.Preparation of a good treatment which imparts water repellency and fungus resistance to 3.kiln-dried lumber. 
4.Preparation of catalysts for polymerizing olefin oxides and olefin sulfides. 
5.Preparation of textile assistants.
