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.

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.

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).

정의

ChEBI: Triethanolamine is a tertiary amino compound that is ammonia in which each of the hydrogens is substituted by a 2-hydroxyethyl group. It has a role as a buffer and a surfactant. It is a tertiary amino compound, a triol and an amino alcohol. It is functionally related to a triethylamine. It is a conjugate base of a triethanolammonium.

제조 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.

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.

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 ga搜索引擎优化us hydrogen is generated in combination with strong reducing agents, such as hydrides. Reacts violently with strong oxidants. [Handling Chemicals Safely 1980. p. 928].

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.

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.

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.

Carcinogenicity

Results of carcinogenicity studies have been controversial. Hoshino and Tanooka reported that triethanolamine in the diet of mice at levels of 0.03% or 0.3% caused a significant increase in the occurrence of tumors, both benign and malignant. Females showed a 32% increase, mostly of thymic lymphomas. The increase of all other tumors, in both sexes, was 8.2%. They also found that triethanolamine reacted with sodium nitrite to produce N-nitrosodiethanolamine and that the product caused mutagenesis in bacteria. Maekawa et al. reported that no carcinogenic activity was found when given orally to rats in drinking water at concentrations of 1% and 2% for 2 years. However, the dosage to females was halved after week 69 of treatment owing to nephrotoxicity. Histological examination of renal damage in treated animals revealed acceleration of chronic nephropathy, mineralization of the renal papilla, nodular hyperplasia of the pelvic mucosa, and pyelonephritis with or without papillary necrosis. Nephrotoxicity seemed to affect life span adversely, especially in females. Tumor incidence and histology were the same in the treated group as in controls.

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.

Purification Methods

Shake the amine gently with Linde type 4A molecular sieves for 24hours, filter and fractionate it under a vacuum, and preferably in the presence of N2. Store it in dark stoppered bottles under N2 as it is hygroscopic, and turns brown in air and light. It has a strong ammoniacal odour (like diethanolamine). It is miscible with H2O, MeOH and Me2CO, and its solubilities at 25o in n-heptane, Et2O and *C6H6 are 0.4%, 1.6% and 4.2%, respectively. [See diethanolamine above, Beilstein 4 IV 1524.]

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.
