Trolamine CAS 102-71-6

alias: triethanolamine

Formula: C6H15NO3

Molecular weight: 149.1882

Boiling point (°C, 101.3kPa): 360

Melting point (°C): 21.2

Relative density (g/ml, 20/4°C): 1.1242

CAS Number: 102-71-6

Characteristics: Colorless to light yellow transparent viscous liquid, slightly ammonia smell, colorless to yellowish cubic crystals at low temperature.

The color gradually darkens when exposed in the air. It is easily soluble in water, ethanol, acetone, glycerin and ethylene glycol, etc., and slightly soluble in benzene, ether and carbon tetrachloride, etc., and is almost insoluble in non-polar solvents. Solubility at 5°C: benzene 4.2%, ether 1.6%, carbon tetrachloride 0.4%, n-heptane less than 0.1%。 It is strongly alkaline, and the pH of 0.1mol/L aqueous solution is 10.5. It is irritating. Hygroscopic. It can absorb acidic gases such as carbon dioxide and hydrogen sulfide. Pure triethanolamine does not work on steel, iron, nickel and other materials, but is highly corrosive to copper, aluminum and their alloys. Unlike monoethanolamine and diethanolamine, triethanolamine and iodine hydroacid (HI) can form iodine hydrochloride precipitate. Combustible. Low toxicity. Avoid contact with oxidants and acids.

How to use:

– Used as raw materials for synthesizing surfactants, detergents, stabilizers and fabric softeners.

– Used in cosmetic formulations to neutralize soap with fatty acids and synthesize amine salts from sulfated fatty alcohols.

 Waste gas treatment neutralizes the cleaning liquid to remove acid gases such as hydrogen sulfide and carbon dioxide.

It is also used as a vulcanization activator for natural rubber and synthetic rubber, and as a polymerization activator for nitrile rubber.

 It is also used as an anti-corrosion additive for lubricating oil, dye solvent, papermaking auxiliary, ink, etc.

Other Uses:

1. Raw materials for detergents, beauty products, skin care products, and cosmetics.

2. Triethanolamine is also a highly effective chelating agent that can chelate various heavy metals.

3. Triethanolamine is also a good solvent, hygroscopic agent, and is used in the textile industry.

4. It also has the effect of neutralizing agent in cosmetics, which can be neutralized with CP-940 to achieve thickening and moisturizing effects.

5. Raw materials for concrete superplasticizer and early strength agent.

6. Used in surfactants, cutting oils, antifreeze, in the metalworking industry, it can be used to prepare corrosion inhibitors, protect metal surfaces, and prevent oxidation.

Triethanolamine acts as a neutralizer in cosmetics. It can be neutralized with CP-940 to achieve a thickening and moisturizing effect. Used as an emulsifier, moisturizer, humidifier, thickener, PH balancer in cosmetics (including skin washing, eye gel, moisturizing, shampoo, etc.). Cream products made with triethanolamine have the characteristics of delicate paste and bright white.

In cosmetic formulations, it is used to neutralize soap with fatty acids and aminoforming salts with sulfated fatty acids. Triethanolamine is a commonly used emulsifier in cream preparations, and cream products emulsified with triethanolamine have the characteristics of delicate paste and bright white. In addition, the colloidal phase formed by triethanolamine and higher fatty acids or higher fatty alcohols has good stability, stable product quality, and high proportion of added components. Triethanolamine is the most commonly used neutralizer for acidic polymer gels containing carbomer, which forms a stable polymer structure by neutralizing with carboxyl groups such as carbomer, achieving the application effect of thickening and moisturizing.

Triethanolamine can be used for industrial gas purification, pH control stabilizer, rubber vulcanization accelerator, developer stabilizer, engine carbon deposition preventor, vulcanization activator for natural rubber and synthetic rubber, nitrile rubber polymerization activator, and can also be used as lubricating oil and anti-corrosion additive. Triethanolamine needs to develop in the direction of more refinement, higher purity and diversification in the future.
