[General Description]

Oily colorless liquid or solid white crystals. Slight rotten fish or ammonia odor. Denser than water.
[Reactivity Profile]

DIETHANOLAMINE(111-42-2) is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. This compound is hygroscopic. DIETHANOLAMINE(111-42-2) may be sensitive to exposure to air and light. This compound can react with oxidizing materials, acids, CO2, copper alloys, aluminum, zinc, galvanized iron and copper.
[Air & Water Reactions]

Water soluble.
[Health Hazard]

Irritation of eyes and skin. Breathing vapors may cause coughing, a smothering sensation, nausea, headache.
[Potential Exposure]

Monoethanolamine is widely used in industry for scrubbing acid gases and in production of detergents and alkanolamide surfactants; to remove carbon dioxide and hydrogen from natural gas, to remove hydrogen sulfide and carbonyl sulfide; as an alkaline conditioning agent; as an intermediate for soaps, detergents, dyes, and textile agents. Diethanolamine is an absorbent for gases; a solubilizer for 2,4- dichlorophenoxyacetic acid (2,4-D); and a softener and emulsifier intermediate for detergents. It also finds use in the dye and textile industry. Triethanolamine is used as plasticizers, neutralizer for alkaline dispersions; lubricant additive; corrosion inhibitor; and in the manufacture of soaps, detergents, shampoos, shaving preparations; face and hand creams; cements, cutting oils, insecticides, surface active agents; waxes, polishes, and herbicides.
[Fire Hazard]

Special Hazards of Combustion Products: Irritating vapors are generated when heated.

[Description]

Diethanolamine is an organic base which has been used as an emulsifying and dispersing agent.It can also be used as a basic buffer, with optimal pH about pH 9, if titrated with HCl or other acid. Other uses include: to "scrub" gases, as a chemical intermediate, as humectant or softening agent.
[Waste Disposal]

Controlled incineration; incinerator equipped with a scrubber or thermal unit to reduce nitrogen oxides emissions
[Preparation]

Diethanolamine is prepared commercially by the ammonolysis of ethylene oxide. The reaction yields a mixture of monoethanolamine, diethanolamine, and triethanolamine which is separated to obtain the pure products.
[Production Methods]

Diethanolamine is produced with monoethanolamine and triethanolamine by ammonolysis of ethylene oxide; diethanolamine is then separated by distillation (Mullins 1978). In 1984, 166.2 million pounds of diethanolamine were produced in the United States (USTIC 1985).
[Flammability and Explosibility]

Nonflammable
[Chemical Reactivity]

Reactivity with Water : No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Flush with water; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
[Pharmaceutical Applications]

Diethanolamine is primarily used in pharmaceutical formulations as a buffering agent, such as in the preparation of emulsions with fatty acids. In cosmetics and pharmaceuticals it is used as a pH adjuster and dispersant.
Diethanolamine has also been used to form the soluble salts of active compounds, such as iodinated organic acids that are used as contrast media. As a stabilizing agent, diethanolamine prevents the discoloration of aqueous formulations containing hexamethylenetetramine-1,3-dichloropropene salts.
Diethanolamine is also used in cosmetics.
[Industrial uses]

Diethanolamine undergoes reactions characteristic of secondary amines and of alcohols. Two industrially important reactions of the ethanolamines involve reaction with carbon dioxide or hydrogen sulfide to yield water soluble salts, and reaction with long chain fatty acids to form neutral ethanolamine soaps (Mullins 1978). Substituted ethanolamine compounds, such as soaps, are used extensively as emulsifiers, thickeners, wetting agents, and detergents in cosmetic formulations (including skin cleaners, creams, and lotions) (Beyer et al 1983).
Diethanolamine is used as a dispersing agent in various agricultural chemicals, as an absorbent for acidic gases (hydrogen sulfide and carbon dioxide), as a humectant, as an intermediate in the synthesis of morpholine, as a surface-active agent in cutting fluids, as a corrosion inhibitor, as a component in textile specialty agents, and as a secondary vulcanization accelerator in the rubber industry. Diethanolamine is also used in cleaners and pharmaceutical ointments, in polyurethane formulations, in herbicides, and in a variety of organic syntheses (Beyer et al 1983; Mullins 1978; Windholz 1983). Diethanolamine is permitted in articles intended for use in the production, processing, or packaging of food (CFR 1981), and is permitted as a secondary direct food additive from use in delinting cottonseed in the production of cottonseed oil or meal cake (Fed. Reg. 1982). Because of the wide industrial and consumer uses, large amounts of this chemical are discharged into water and sewage in an unaltered form (Yordy and Alexander 1981).
[Safety]

Diethanolamine is used in topical and parenteral pharmaceutical formulations, with up to 1.5% w/v being used in intravenous infusions. Experimental studies in dogs have shown that intravenous administration of larger doses of diethanolamine results in sedation, coma, and death.
Animal toxicity studies suggest that diethanolamine is less toxic than monoethanolamine, although in rats the oral acute and subacute toxicity is greater. Diethanolamine is said to be heptacarcinogenic in mice and has also been reported to induce hepatic choline deficiency in mice.
Diethanolamine is an irritant to the skin, eyes, and mucous membranes when used undiluted or in high concentration. However, in rabbits, aqueous solutions containing 10% w/v diethanolamine produce minor irritation. The lethal human oral dose of diethanolamine is estimated to be 5–15g/kg body-weight.
The US Cosmetic Ingredient Review Expert Panel evaluated diethanolamine and concluded that it is safe for use in cosmetic formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin. In products intended for prolonged contact with the skin, the concentration of ethanolamines should not exceed 5%. Diethanolamine should not be used in products containing N-nitrosating agents.

[Carcinogenicity]

When DEA was administered cutaneously to pregnant rats and rabbits during organogenesis, developmental toxicity (skeletal variations) was observed only in the rat and only at doses causing significant maternal toxicity.
The 2003 ACGIH threshold limit valuetime- weighted average (TLV-TWA) is 3ppm (13mg/m3).
[Metabolism]

Treatment of Wistar or Sherman rats with diethanolamine caused increases in the formation of hepatic phospholipids (Artom et al 1949). In addition, dietary administration led to incorporation of ethanolamine into hepatic phospholipids (Artom et al 1949), and repeated oral administration of diethanolamine in drinking water (one to three wk) at a dose of 320 mg/kg/d was found to reduce the level of incorporation of ethanolamine and choline into hepatic and renal phospholipids in Sprague-Dawley rats (Barbee and H?rtung 1979b).
Dermal absorption of diethanolamine is suggested to occur in rats since Nnitrosodiethanolamine was excreted in the urine of male Sprague-Dawley rats which had been administered diethanolamine by dermal application and given nitrite in their drinking water (Preussman et al 1981).
[storage]

Diethanolamine is hygroscopic and light- and oxygen-sensitive; it should be stored in an airtight container, protected from light, in a cool, dry place.
[Purification Methods]

Fractionally distil the amine twice, then fractionally crystallise it from its melt. Its solubility in H2O is 10% at 20o. [Perrin & Dempsey Buffers for pH and Metal Ion Control Chapman & Hall, London 1974, Beilstein 4 H 283, 4 II 729, 4 III 689, 4 IV 1514.]
