ETHANOLAMINES

GCIN02 – 08/00

USES

DetergentsMONOETHANOLAMINE, DIETHANOLAMINE and TRIETHANOLAMINE are recommended as

components in detergent formulations for laundry and dishwashing, degreasers, multiple use

detergents and disinfectants.

TRIETHANOLAMINE is recommended as an alkalizing agent for dodecylbenzene sulfonic

acid, resulting in the formation of an organic salt that is more soluble in water than

sulfonic acid neutralized with sodium hydroxide, promoting the obtainment of liquid

detergents for manual dish washing with a lower cloud point and greater stability, making

the use of hydrotopes such as urea unnecessary.

TRIETHANOLAMINE can also be used to alkalize long-chain fatty acids such as lauryl,

ricinoleic, oleic and stearic acids, forming TRIETHANOLAMINE soap that is soluble in water

with an emulsifying effect in liquid soap-base detergent formulations and in transparent

pine oil-based disinfectants, promoting a blooming effect when the disinfectant is diluted

in water.

Since it is a weak base, TRIETHANOLAMINE can be used as an neutralizer agent in car wash

shampoos, polishing waxes, degreasing non-corrosive detergents, liquid laundry detergents

and multiple use cleaners.

MONOETHANOLAMINE and DIETHANOLAMINE can also be used as neutralizer agents in

formulations of car wash shampoos, degreasers in general, wax removers and as

corrosion inhibitors.

Agrochemicals

MONOETHANOLAMINE, DIETHANOLAMINE and TRIETHANOLAMINE are used as neutralizer

agents for anionic emulsifiers.

DIETHANOLAMINE and TRIETHANOLAMINE can be used in the preparation of agricultural

compounds obtained from 2,4D acid (2,4 dichloro phenoxiacacetic) and

DIETHANOLAMINE can be used in the synthesis of glyphosate.

Treatment of gases

Ethanolamines can be used to treat natural gas and petroleum residual gas in the absorption

of carbon dioxide. In gas systems containing carbon dioxide, MONOETHANOLAMINE can be

used as a selective absorber, and plays an important role in the production of ammonia, liquid

carbon dioxide and dry ice permitting regeneration in the latter cases. DIETHANOLAMINE is

recommended for the treatment of vapors with a high content of hydrogen sulfide.

Additives for cement

Ethanolamines are used as auxiliary agents in concrete milling. Low concentrations of

TRIETHANOLAMINE accelerate the hardening rate of concrete while high concentrations have

a retarding effect on hardening.

Other uses

MONOETHANOLAMINE and DIETHANOLAMINE are recommended as synthesis intermediates

for the manufacture of corresponding alkanolamides (ALKOLAN PK and ALKOLAN CO lines)

due to their reaction with fatty acid or coconut oil. As a consequence of their properties, these

products can be used in various industrial segments such as detergents, lubricant oils,

products for hygiene and personal care, flotation of minerals, etc.

Ethanolamines can also be used in the formulation of pharmaceutical products, dispersing

agents for glues, gums, latex and photographic developers, accelerators of rubber

vulcanization, corrosion inhibitors, pH controllers, synthesis intermediates, lacquer, paint, wax

and polisher wetting agents, polymerizing agents and catalysts for polyurethane resins.

HANDLING AND STORAGE

MONOETHANOLAMINE, DIETHANOLAMINE and TRIETHANOLAMINE and their respective

concentrated solutions are irritant when in contact with the skin and eyes. Extended

contact with the skin can cause irritation to the immediate area and possibly chemical

burns. Vapors and aerosols produced by heating or violent movement can irritate the

respiratory tract.

When handling the products we recommend the use of individual protection equipment

such as rubber or PVC gloves, a PVC apron and safety goggles. In the case of exposure to

high concentrations, use masks designed for protection against organic vapors.

In the event of accidental contact proceed as follows:

• eyes: wash immediately with running water for at least 15 minutes;

• skin: wash the areas affected with plenty of water and remove contaminated clothing;

• ingestion: seek medical care.

We recommend storing MONOETHANOLAMINE, DIETHANOLAMINE and

TRIETHANOLAMINE by bulk in stainless steel 316 or 304 tanks or in carbon steel tanks

coated with PEAD/PEBD Liner, equipped with a water or vapor heating coil to maintain the

products at a temperature above their solidification point. Storage in carbon steel tanks

without covering can compromise the color of the product, which becomes yellow as a

result of iron contamination. Pipes can be made from carbon steel or stainless steel.

Tanks coated with epoxy resin reinforced with fiberglass can be corroded as a result of

the alkalinity of the amine. Polyethylene tanks are not proper for handling in the case of

DIETHANOLAMINE and TRIETHANOLAMINE 99, since these products require heating

during storage and handling.

Since these products are hygroscopic we recommend provide the tanks with an inert

atmosphere such as of nitrogen to reduce the absorption of water and to avoid darkeningthrough contact with the air.

Since the products are combustible, they must be protected from sources of ignition such as

open flames, heated surfaces, electric discharges, etc. The extinguishing agents are water, dry

chemical, carbon dioxide and foam.

Exposure to light should be avoided since the products become slightly yellow. Copper

and its alloys such as brass should not be used in the storage and transfer equipment

since they form complex salts with MONOETHANOLAMINE, DIETHANOLAMINE and

TRIETHANOLAMINE, and the products become slightly blue.

TRIETHANOLAMINE is a chemical product controlled by the Brazilian Ministry of Armed

Forces, thus registration is required prior to sale and use.

The shelf life of the products are listed below and are counted as from the date of manufacture

and are guaranteed provided the products are maintained in their original packaging and

stored under adequate conditions. The principal quality requirement related to the shelf life is

the color, which can become yellow after the stipulated period.
