개요

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.

화학적 성질

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.

화학적 성질

Clear, amber viscous liquid

화학적 성질

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

화학적 성질

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).

화학적 성질

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.

용도

TEA (triethanolamine) is an emulsifier and pH adjuster.

용도

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.

정의

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

생산 방법

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.

생산 방법

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).

상표명

Mobisyl [as salicylate] (Ascher);Sabrilex.

Composition

The dried leaves contain protein, 25.7%; fat, 6.5%; carbohydrate, 40.8%; ash, 5%; caffeine, 3.3% and tannin, 13%. 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.

일반 설명

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

공기와 물의 반응

Water soluble.

반응 프로필

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].

건강위험

Liquid may irritate eyes and skin.

건강위험

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.

건강위험

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).

화재위험

Special Hazards of Combustion Products: Poisonous gases, such as NOx, may be produced

화학 반응

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Dilute with water; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

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.

공업 용도

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).

색상 색인 번호

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

잠재적 노출

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.

저장

Triethanolamine may turn brown on exposure to air and light.
The 85% grade of triethanolamine tends to stratify below 15℃; homegeneity can be restored by warming and mixing before use. Triethanolamine should be stored in an airtight container protected from light, in a cool, dry place.
See Monoethanolamine for further information.

운송 방법

비 호환성

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.
