AkzoNobel manufactures EO and other ethylene amines at their facilities in Stenungsund,
Sweden and Ningbo, China. Ethylene Amines are particularly reactive molecules making them a
versatile tool for building new molecules for a wide range of applications. They have the ability to
change the properties of chemical products, making them softer, firmer, or more supple. They
can prevent coagulation or increase flow. Ethylene oxide is a key ingredient in the manufacturing
of ethylene amines. Ethylene amines are manufactured using main raw materials ethylene,
oxygen, and ammonia. They are produced when monoethanolamine and ammonia react under
high pressure and at a high temperature in the presence of hydrogen and a catalyst.
EO is a cyclic ether composed of two alkyl groups connected to an oxygen atom. Ethylene oxide
is used industrially to make many consumer products as well as non-consumer chemicals and
intermediates. It is industrially produced by direct oxidation of ethylene in the presence of a silver
EO has applications in the production of solvents, antifreeze, textiles, detergents, adhesives,
polyurethane foam, and pharmaceuticals. Other applications include manufacture of Ethylene
glycol, polyglycols, ethanolamines, and cellulose ethers. Smaller applications of EO include in
fumigants, sterilants for spices and cosmetics, as well as during hospital sterilization of surgical
EO is a clear colorless liquid with a sweet odor. EO is miscible in water, ethanol, acetone, ether,
benzene, and hexane. EO is an extremely flammable substance, even at room temperature.

Primary routes of exposure are skin contact, eye contact, and inhalation. EO is a skin irritant and
may degrease the skin. It can be absorbed through the skin and may lead to dermatitis. This
product can cause serious eye irritation. EO is toxic through inhalation and is irritating to the
respiratory system. Inhalation of aerosols may cause irritation to the mucous membranes. If
ingested, this product can cause severe irritation of the throat, esophagus, and stomach.
Persons with pre-existing skin and/or respiratory disease may be at increased risk if exposed to
this material.
EO is listed as a category 2 carcinogen and is carcinogenic to man. EO is mutagenic according
to Ames test and has reproductive toxicity. EO may cause cancer and heritable genetic damage,
based on animal studies.
Consumer and worker exposure is very unlikely as this substance is manufactured and handled
in industrial settings in closed systems. AkzoNobel is dedicated to designing, constructing and
maintaining production and handling systems that eliminate exposure to EO.
The environmental exposure of EO is not harmful to the environment, but may be harmful to
aquatic life. EO breaks down rapidly when released into the environment and does not persist
long in the environment. EO is readily biodegradable and is not expected to bioaccumulate due
to the low log Pow value. EO will dissolve in water and absorption to the solid soil particles is not
expected. This substance is not considered to be a PBT or vPvB (Persistent, Bioaccumulative,
Toxic or very Persistent nor very Bioaccumulating).
As indicated, harmful exposure effects of EO to the body are worth noting. EO is extremely toxic
and flammable. Proper PPE should be used when handling EO.
Keep away from sunlight, sources of ignition, static discharge and don’t expose to temperatures
exceeding 50 °C.
Elevated temperatures can cause ignition leading to thermal decomposition and release of
hazardous gases.
For these reasons AkzoNobel provides training and information to users of EO and to emergency
Consumers will not come into contact with EO as it is manufactured in a closed process which
also minimizes employee exposure potential. Exposure to EO in the environment or personnel in
manufacturing facilities is also considered very low because the process, storage and handling
operations are enclosed.
In general, obtain medical attention immediately if there is any exposure to EO on the skin, eyes,
inhalation, or ingestion. AkzoNobel takes great effort to prevent accidents of any kind related to
Strict controls are in place to avoid worker exposure including the use of personal protective
equipment and redundant safety systems.
Any EO leaks or spills should only be handled by trained emergency response personnel wearing
the appropriate PPE (Protective suit and boots, Butyl rubber gloves, tightly fitted splash goggles,
and a NOISH approved positive-pressure demand, self-contained breathing apparatus).
Engineering Controls
EO must be handled and stored in a properly designed environment. Avoid contact with skin,
eyes, direct inhalation or ingestion. Sufficient natural or mechanical exhaust ventilation must be
provided at all times to help minimize exposure level. If ventilation is not adequate, use a NIOSH
approved organic vapor acid gas (OVAG) respirator with dust, mist, and fume filter to reduce
exposure. Containers should be kept tightly capped and stored in a cool, dry, well-ventilated area
away from incompatible materials, sources of heat, flame, or direct sunlight. Ensure that
eyewash stations and safety showers are easily assessable. Please consult MSDS for specific
control measures to be taken.
Personal Protective Equipment
Protective suit and boots, Butyl rubber gloves, and chemical safety splash goggles or face shield
are recommended. Use a NOISH approved organic vapor respirator with dust, mist, and fume
filters. If a higher level of protection is needed, use a NIOSH-approved positive pressure demand,
air-supplied respirator. When using respirator cartridges or canisters, they must be changed
frequently. Please contact AkzoNobel for specific recommendations on PPE.
AkzoNobel takes great care in the production, handling, and transport of this product. It is our
highest priority in making sure they are safe for our employees and for our neighbors.
We have been certificated in accordance with the ISO 14001 Environmental Management
System since 1999, certificated in accordance with ISO 9001, and SS 627750 Energy certified.
We offer safety data sheets containing information on properties, handling, precautions, and firstaid procedures. We offer an Ethylene Best Practices Manual, giving more detailed
recommendations on the proper use and handling of ethylene amine products. Life Cycle
Assessment documentation on our products is available on request.
We have also adopted the principles of the chemical industry’s Responsible Care program for
continuous improvement in the aspects of health, safety, and environment. Potential risks from
the plant and from transport of hazardous goods are investigated and monitored. These
investigations are followed up and risk reducing measures are implemented.
We employ intermodal transport to transport the load effectively, both from an environmental and
economic perspective. In addition, emissions to water from the site have been reduced
substantially as a result of a larger share of process water being incinerated, and by improving
procedures and equipment.

AkzoNobel Ethylene Amines Product Information
EO is regulated for transport by the ADR, RID, IMDG, and IATA. It is classified as a toxic
flammable substance and is listed in the Hazardous Materials Table under UN number 1040.
Flammable and toxic labels are required for transport.
Worker Safety
Some Occupational Exposure Limits have been established by international organizations for the
safe handling of EO in the workplace. Proper engineering controls, personal protective
equipment and workplace exposure monitoring must be followed to adhere to these standards.
Use and Disposal
Do not dispose of waste in sewer systems. Do not contaminate ponds, waterways, or ditches
with chemical or used container. Remaining contents should be emptied accordingly and empty
drum shouldn’t be burned. The use and disposal of EO are subject to various international laws
and regulations. In the EU, EO is subject to REACH regulations.
Additional regulations may exist that govern the manufacture, sale, transportation, use and/or
disposal of EO. These regulations may vary by city, state, country or geographic region.
Additional helpful information may be found by consulting the relevant Material Safety Data Sheet.
EO has major applications in the manufacture of Ethylene glycol, polyglycols,
ethanolamines, and cellulose ethers among other applications.
EO is extremely toxic and flammable. Avoid ignition sources and elevated storage
temperatures which may lead to thermal decomposition and release of toxic gases.
Exposure to EO can cause harmful health effects and should therefore be avoided.
