Triethanolamine Chemical Properties,Uses,Production

General description

Triethanolamine appears as colorless oily liquid with the smell of ammonia. It is easy to absorb water and will turn into brown color when being exposed to the air and the light. At low temperature, it will become colorless or pale yellow cubic crystal. It has a melting point of 21.2 ℃, boiling point of 335.4 ℃, 277 ℃ (19.950kPa), 206~207 ℃ (1.995kPa), relative density of 1.1242, the refractive index of 1.4852. Its Kb is 2.5 × 10-10 with the pH of its 1.0 mol/L aqueous solution being 10.5. It is miscible with water, methanol and acetone. It is soluble in benzene, ether, slightly soluble in carbon tetrachloride, n-heptane. It is a kind of strong alkaline, combining with protons, can be used for condensation reaction.
In analytical chemistry, triethanolamine can be used as the stationary phase for the gas liquid chromatography (the maximum temperature is 75 ℃ with the solvent being methanol and ethanol), used for the separation of pyridine and methyl substitutes. In the complexometric titration and other analysis, it can be used as a masking agent for interfering ions. For example, in a solution of pH = 10, when we apply EDTA for titration of magnesium, zinc, cadmium, calcium, nickel and other ions, the reagent can be used for masking titanium, aluminum, iron, tin and some other ions. In addition, it can also be dubbed with hydrochloric acid into a buffer solution of a certain pH value.
Triethanolamine is mainly used in the manufacture of surfactants, liquid detergents, cosmetics and so on. It is one of the components of cutting fluid and antifreeze fluid. During the nitrile rubber polymerization, it can be used as an activator, being the vulcanization activator of natural rubber and synthetic rubber. It can also be used as the emulsifiers of oil, wax and pesticides, the moisturizer and stabilizer of cosmetics, textile softeners as well as the anti-corrosion additives of lubricants. Triethanolamine is also capable of absorbing carbon dioxide and hydrogen sulfide and other gases. During the cleaning of the coke oven gas and other industrial gases, it can be used for removal of acid gases. It is also a commonly used masking agent in the EDTA titration assay.
China provided the allowable concentration in the air is 3 μg/g.

Dermatology drug for external use

At present, the dermatology of many hospitals commonly used the topical drug, Biafine for the treatment of burns and skin trauma with the main ingredient being triethanolamine. Triethanolamine can play a dual effect of cleaning and drainage through the principle of penetration and capillary action, being able to further increase the skin blood flow velocity and helping the discharge of exudate. It can also change the ratio between interleukin 1 and interleukin VI, stimulating the proliferation of fibroblast and increasing the collagen synthesis. It is clinically used for the treatment of secondary erythema caused by the radiation therapy as well as degree I, degree II burns and skin trauma that has not yet infected.
(1) radiation-induced skin damage: Recommended: application of 2 to 3 times with each administration within the same interval; gently massage to make the skin absorb it.
(2) Ⅱ-degree burns and other skin trauma: After cleaning the wounds, apply a thick layer of drug on the wound surface; repeat the application to make trauma be treated with a sufficient amount of drugs. If necessary, apply a moist wet dressing for wrapping. Do not use dry absorbent dressing.
(3) Ⅰ degree burns: Apply a thick layer until the skin doesn’t absorb the drug anymore and gently massage. Repeat 2 to 4 times a day.

Early strength agent

Triethanolamine is currently a commonly used early strength agent used in China's cement industry with the effect of early strength agent being accelerating hydration process of the cement in the presence of liquid phase in the concrete to improve the early strength. Although triethanolamine does not change the hydration product of cement, it can enhance the activity of the colloid generated through the hydration of cement, producing pressure to surrounding regions, blocking the capillary channel, exacerbating the effect of the adsorption, wetting and dispersion of particles and so on, promoting the reaction of the formation of hydrated calcium sulfoaluminate between the C3A and gypsum. This can improve the density of concrete, anti-permeability and antifreeze property, playing the role of early strength and enhancing the strength.
When used in combination with inorganic salts, it can play a catalytic role due to the hydration of cement itself and the reaction between inorganic salts and cement, so that the effect of early strength is particularly significant in the case.

Chemical properties

At room temperature, it appears as colorless transparent viscous liquid with hygroscopicity and ammonia smell. It is alkaline, being irritating. It has a melting point of 21.2 °C, the boiling point of 360 °C, a flash point of 193 ° C, the relative density (d420) 1.1242 and refractive index (nD20) of 1.4852. It is miscible with water, ethanol and acetone, slightly soluble in ether, benzene and carbon tetrachloride.

Uses

(1) GB 2760-96 provides it as allowable food processing aids with GMP as limit.
(2) It can be used as the cleaning liquid for the removal of carbon dioxide and hydrogen sulfide in the gas. Esters generated from the reaction between triethanolamine and higher fatty acids are widely used as detergents, emulsifiers, wetting agents and lubricants as well as for the preparation of cosmetic balsam. Triethanolamine can also be used as preservatives and waterproofing agents, analysis reagents and solvents. In the nitrile rubber polymerization, it is used as an activator. It can also be used as the emulsifier, stabilizer, textile softer of oil and wax. It is one of the components of oiling agent of synthetic fiber.

Description

Triethanolamine is a viscous, colourless/pale yellow liquid with a weak ammoniacal odour. Triethanolamine is incompatible with copper, copper alloys, galvanised iron, acids, and oxidisers. Reports indicate that in India itself, as many as six companies manufacture triethanolamine and it is manufactured by many different countries around the world. Global production and industrial application of triethanolamine is very extensive.
In industries, triethanolamine is used as a corrosion inhibitor in metal-cutting fluids; a curing agent for epoxy and rubber polymers; a copper–triethanolamine; in emulsifiers, thickeners, and wetting agents in the formulation of consumer products such as cosmetics, detergents, shampoos, and other personal products; and a neutraliser-dispersing agent in agricultural herbicide formulations. In brief, triethanolamine has wide applications as a corrosion inhibitor, a surface-active agent, and an intermediate in various products including metalworking fluids, oils, fuels, paints, inks, cement, cosmetic, and personal products and formulations of algicides and herbicides.

Chemical Properties

Triethanolamine is a pale yellow and viscous liquid. It is hygroscopic with an irritant and ammoniacal odor. There are multiple industrial and domestic applications for this compound, i.e., in the manufacture of toilet products, cosmetics formulations, solvents for waxes, resins, dyes, paraffi ns and polishes, herbicides, and lubricants for textile products. In the pharmaceutical industry, triethanolamine is used as a non-steroidal, antiinfl ammatory agent, an emulsifi er, and an alkylating agent.

Chemical Properties

Ethanolamines can be detected by odor as low as 23 ppm. Monoethanolamine is a colorless, viscous liquid or solid (below 111C) with an unpleasant, ammonialike odor

Chemical Properties

Clear, amber viscous liquid

Chemical Properties

Triethanolamine is a clear, colorless to pale yellow-colored viscous liquid having a slight ammoniacal odor. It is a mixture of bases, mainly 2,2’,2’’-nitrilotriethanol, although it also contains 2,2’- iminobisethanol (diethanolamine) and smaller amounts of 2- aminoethanol (monoethanolamine).

Chemical Properties

A shrub having lanceolate leaves and rather large, fragrant white flowers. The plant is extensively cultivated in India, Java, Ceylon, China and Japan for its leaves used in the preparation of the beverage. The seeds of the plant contain a fixed oil that is used for industrial purposes. The green tea leaves contain a very small amount of essential oil (0.014%, spring; 0.007%, summer). The leaves are cured by the following process: The leaves are dried and comminuted, thus liberating the juice containing enzymes necessary for fermentation. Fermentation is carried out for about 4 hours, changing the color of the leaves from green to dark brownishgreen. Finally, a stream of hot air is passed over the cured leaves to stop fermentation and to reduce moisture content to approximately 2%. The dried, cured leaves are the part used. Tea has a sweet, herbaceous, woody, floral odor.

Uses

TEA (triethanolamine) is an emulsifier and pH adjuster.

Uses

Triethanolamine is used primarily as a surfactant, reducing the surface tension between two media. It is also used as a general emulsifier for preparations, such as ones involving drug penetration ass ays.

Definition

ChEBI: A tertiary amino compound that is ammonia in which each of the hydrogens is substituted by a 2-hydroxyethyl group.

Production Methods

Triethanolamine is produced with ethanolamine and diethanolamine by ammonolysis of ethylene oxide and the triethanolamine is then separated by distillation (Mullins 1978). In 1984, 139.6 million pounds of triethanolamine were produced in the United States (USTIC 1985).

Production Methods

Triethanolamine is prepared commercially by the ammonolysis of ethylene oxide. The reaction yields a mixture of monoethanolamine, diethanolamine, and triethanolamine, which are separated to obtain the pure products.

The most common catechins are gallic esters (epicatechin, epicatechin gallate and epigallocatechin gallate). All are found in green tea and are claimed to be responsible for the chemopreventive benefits of the beverage.

World Health Organization (WHO)

Trolamine is widely used as an emulsifier in combination with fatty acids in pharmaceutical and cosmetic products. The World Health Organization is not aware of restrictive action having been taken elsewhere.

General Description

Oily liquid with a mild ammonia odor. Denser than water. Freezing point is 71°F.

Air & Water Reactions

Water soluble.

Reactivity Profile

Triethanolamine is an aminoalcohol. Neutralize acids to form salts plus water in exothermic reactions. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides. Reacts violently with strong oxidants. [Handling Chemicals Safely 1980. p. 928].

Health Hazard

Liquid may irritate eyes and skin.

Health Hazard

Exposures to triethanolamine, in contrast with other chemical compounds, is known to cause low toxicity to animals and the acute oral LD50 to rats and guinea pigs ranges from 8000 to 9000 mg/kg. Triethanolamine was found to be a moderate eye irritant. A 5%–10% solution of triethanolamine did not induce skin irritation or skin sensitization. Studies of Inoue et al. and many other workers have indicated the absence of the mutagenic potential of triethanolamine as evidenced by both in vivo and in vitro studies (Salmonella typhimurium tests, Chinese hamster ovary cells, and rat liver chromosome analysis). Further, extensive studies have demonstrated the absence of potential carcinogenicity of triethanolamine in rats and mice, suggesting a low or lack of acute or chronic toxicity of the chemical to mammals.

Health Hazard

The estimated fatal dose of triethanolamine in humans is 50 g (Dreisbach 1980). Human exposure to ethanolamines include oral exposure to non-standard foods and ethical drugs, dermal exposure to cosmetics, proprietary drugs, and adhesives and sealants, and inhalation exposure to adhesives, sealants, and cutting fluids. The National Occupational Hazard Survey (NIOSH 1976) indicated that 1.66 million workers are potentially exposed to triethanolamine. Approximately 780,000 workers are estimated to be exposed to lubricating and cutting fluids containing triethanolamine in the process of cutting and grinding metals. Triethanolamine has been identified as an air pollutant by the Pollutant Strategies Branch of the U.S. EPA (CIS 1979).
In a safety assessment report on ethanolamine, diethanolamine and triethanolamine, it was concluded that these chemicals are safe in cosmetic formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin (Beyer et al 1983). The concentration of the three ethanolamines in cosmetic formulations should not exceed 5% in products intended for prolonged contact with the skin. In addition, triethanolamine should not be used in products containing N-nitrosating agents, since these chemicals may be nitrosated to form 7V-nitrosodiethanolamine, a liver and nasal cavity carcinogen (Lijinsky et al 1980; Preussmann et al 1982).

Pharmaceutical Applications

Triethanolamine is widely used in topical pharmaceutical formulations, primarily in the formation of emulsions.
When mixed in equimolar proportions with a fatty acid, such as stearic acid or oleic acid, triethanolamine forms an anionic soap with a pH of about 8, which may be used as an emulsifying agent to produce fine-grained, stable oil-in-water emulsions. Concentrations that are typically used for emulsification are 2–4% v/v of triethanolamine and 2–5 times that of fatty acids. In the case of mineral oils, 5% v/v of triethanolamine will be needed, with an appropriate increase in the amount of fatty acid used. Preparations that contain triethanolamine soaps tend to darken on storage. However, discoloration may be reduced by avoiding exposure to light and contact with metals and metal ions.
Triethanolamine is also used in salt formation for injectable solutions and in topical analgesic preparations. It is also used in sun screen preparations.
Triethanolamine is used as an intermediate in the manufacturing of surfactants, textile specialties, waxes, polishes, herbicides, petroleum demulsifiers, toilet goods, cement additives, and cutting oils. Triethanolamine is also claimed to be used for the production of lubricants for the rubber gloves and textile industries. Other general uses are as buffers, solvents, and polymer plasticizers, and as a humectant.

Industrial uses

Triethanolamine undergoes reactions characteristic of tertiary 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).
The largest uses for triethanolamine are in the production of fatty acid soaps and detergents and in cosmetic formulations. In cosmetics, triethanolamine is an important raw material and is used in combination with fatty acids as emulsifiers for creams, lotions, skin cleaners, and shampoos. Triethanolamine is also used in cement and concrete to reduce particle agglomeration within the grinding mill; as an antistatic agent in the textile industry; in the metal industry for metal plating and in alkaline derusting formulations; in the rubber industry as a vulcanization accelerator; and in the manufacture of herbicides and pesticides. Triethanolamine may also be used as a surface active agent in cutting fluids; as an absorption agent for acidic gases in air pollution control; as a component of coating on fruits and vegetables; as a solvent for casein, shellac, and dyes; and as a penetrating agent for organic liquids in wood and paper (Bayer et al 1983; Mullins 1978; Windholz 1983). Triethanolamine is permitted in articles intended for use in the production, processing, or packaging of food (CFR 1981).

Contact allergens

This emulsifying agent can be contained in many products such as cosmetics, topical medicines, metalworking cut- ting fluids, and color film developers. Traces may exist in other ethanolamines such as monoand diethanolamine. Contact allergy seems to be rarer than previously thought.

Safety Profile

Moderately toxic by intraperitoneal route. Mildly toxic by ingestion. Liver and kidney damage have been demonstrated in animals from chronic exposure. A human and experimental skin irritant. An eye irritant. Questionable carcinogen with experimental carcinogenic data. Combustible liquid when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx and CN-.

Safety

Triethanolamine is used primarily as an emulsifying agent in a variety of topical pharmaceutical preparations. Although generally regarded as a nontoxic material, triethanolamine may cause hypersensitivity or be irritant to the skin when present in formulated products. The lethal human oral dose of triethanolamine is estimated to be 5–15 g/kg body-weight.
Following concern about the possible production of nitrosamines in the stomach, the Swiss authorities have restricted the use of triethanolamine to preparations intended for external use.
LD50 (guinea pig, oral): 5.3 g/kg
LD50 (mouse, IP): 1.45 g/kg
LD50 (mouse, oral): 7.4 g/kg
LD50 (rat, oral): 8 g/kg

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.

Hygroscopic (i.e., absorbs moisture from the air). Corrosive to copper, zinc, and galvanized iron (di-). The aqueous solution is a medium strong base. Attacks copper, zinc, aluminum, and their alloys.

Incompatibilities

Triethanolamine is a tertiary amine that contains hydroxy groups; it is capable of undergoing reactions typical of tertiary amines and alcohols. Triethanolamine will react with mineral acids to form crystalline salts and esters. With the higher fatty acids, triethanolamine forms salts that are soluble in water and have characteristics of soaps. Triethanolamine will also react with copper to form complex salts. Discoloration and precipitation can take place in the presence of heavy metal salts.
Triethanolamine can react with reagents such as thionyl chloride to replace the hydroxy groups with halogens. The products of these reactions are very toxic, resembling other nitrogen mustards.
