Uses and Occurrences:
Ethylene glycol diacetate is used as a solvent for cellulose esters, cellulose ethers, oils, resins, lacquers, natural products and printing inks; as a perfume fixative; and as a nondiscoloring plasticizer for ethyl and benzyl cellulose.(6,9,10)


Colourless liquid with a slight, ethyl acetate or fruity, acid odour. COMBUSTIBLE LIQUID AND VAPOUR. Can form explosive mixtures with air at, or above 88 deg C (191 deg F). Generally has low toxicity.


Effects of Short-Term (Acute) Exposure

Ethylene glycol diacetate does not readily form a vapour at room temperature. Therefore, it must be heated or misted before inhalation exposure would occur. It is unlikely to produce harmful effects, other than irritation, if inhaled. A closely related chemical, ethylene glycol, is irritating to the nose and throat. There is no specific information available.

Skin Contact:
Ethylene glycol diacetate is probably not irritating or a mild irritant, based on limited information for the closely related chemical ethylene glycol monoacetate.
It may be absorbed through the skin, but it is unlikely that harmful effects would occur.

Eye Contact:
Ethylene glycol diacetate is probably not irritating or a mild eye irritant, based on animal information. There is no human information available.

Ethylene glycol diactetate is not expected to be toxic if ingested, based on animal toxicity values. Any harmful effects observed following the ingestion are believed to result from the formation of ethylene glycol in the body.(5) Ethylene glycol can be toxic to humans following ingestion and there have been many non-occupational cases of fatal or near-fatal poisoning from drinking it, either accidentally or intentionally. For additional information on the effects of ethylene glycol, refer to the CHEMINFO review. There is no human information available for ethylene glycol diacetate. Ingestion is not a typical route of occupational exposure.

Effects of Long-Term (Chronic) Exposure

There is no human information available for ethylene glycol diacetate.

Kidneys/Urinary System:
Ethylene glycol diacetate ingestion caused kidney stone formation and kidney damage in animals following ingestion of very large doses. These observations are considered to have little or no relevance to occupational settings because of the large doses used and the fact that ingestion is not a typical route of occupational exposure.


There is no human or animal information available.

The International Agency for Research on Cancer (IARC) has not evaluated the carcinogenicity of this chemical.

The American Conference of Governmental Industrial Hygienists (ACGIH) has no listing for this chemical.

The US National Toxicology Program (NTP) has not listed this chemical in its report on carcinogens.

Teratogenicity and Embryotoxicity:
There is no human or animal information available.

Reproductive Toxicity:
There is no human or animal information available.

There is no human or animal information available.

Toxicologically Synergistic Materials:
There is no information available.

Potential for Accumulation:
Probably does not accumulate. Ethylene glycol diacetate is readily broken down in the body to ethylene glycol and acetic acid.(5)


If symptoms are experienced, remove source of contamination or move victim to fresh air. Obtain medical advice.

Skin Contact:
As quickly as possible, flush with lukewarm, gently flowing water for at least 5 minutes or until the chemical is removed. Remove contaminated clothing, shoes, and leather goods (e.g. watchbands, belts). Obtain medical advice immediately. Completely decontaminate clothing, shoes and leather goods before re-use or discard.

Eye Contact:
Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 5 minutes or until the chemical is removed, while holding the eyelid(s) open. Obtain medical advice immediately.

NEVER give anything by mouth if victim is rapidly losing consciousness, is unconscious or convulsing. Have victim rinse mouth thoroughly with water. DO NOT INDUCE VOMITING. Have victim drink 240 to 300 mL (8 to 10 oz) of water to dilute material in stomach. Obtain medical attention immediately.

First Aid Comments:
Provide general supportive measures (comfort, warmth, rest).
Consult a doctor and/or the nearest Poison Control Centre for all exposures except minor instances of inhalation or skin contact.
All first aid procedures should be periodically reviewed by a doctor familiar with the material and its conditions of use in the workplace.


Flash Point:
88 deg C (191 deg F) (closed cup) (11,13,14)

Lower Flammable (Explosive) Limit (LFL/LEL):
1.6% (11,13,14)

Upper Flammable (Explosive) Limit (UFL/UEL):
8.4% (11,13,14)

Autoignition (Ignition) Temperature:
482 deg C (900 deg F) (11,13,14)

Sensitivity to Mechanical Impact:
Probably not sensitive. Stable material.

Sensitivity to Static Charge:
Ethylene glycol diacetate probably will not accumulate static charge, since esters generally have high electrical conductivities. Mixtures of ethylene glycol diacetate vapour and air at concentrations in the flammable range will not be ignited by a static discharge, since it has a moderately high flash point.

Electrical Conductivity:
Not available

Minimum Ignition Energy:
Not available

Combustion and Thermal Decomposition Products:
Incomplete combustion may produce irritating fumes and acrid smoke.(6)

Fire Hazard Summary:
COMBUSTIBLE LIQUID. Can form explosive mixtures with air at, or above 88 deg C (191 deg F). During a fire, irritating/toxic smoke and fumes may be generated. Closed containers may rupture violently and suddenly release large amounts of product when exposed to fire or excessive heat for a sufficient period of time.

Extinguishing Media:
Carbon dioxide, dry chemical powder, appropriate foam, water spray or fog.(15) Special "alcohol-resistant fire fighting foams" are recommended for use with any polar liquid that is soluble in water, such as ethylene glycol diacetate.(11) Fire fighting foam manufacturers should be consulted for recommendations regarding types of foams and application rates.

Fire Fighting Instructions:
Evacuate area and fight fire from a safe distance or a protected location. Approach fire from upwind to avoid toxic decomposition products.
Closed containers may rupture violently when exposed to the heat of the fire and suddenly release large amounts of products. Stay away from ends of tanks involved in fire, but be aware that flying material (shrapnel) from ruptured tanks may travel in any direction.
If possible, isolate materials not yet involved in the fire, and move containers from the fire area if this can be done without risk, and protect personnel. Otherwise, fire-exposed containers or tanks should be cooled by application of hose streams. Cooling should begin as soon as possible (within the first several minutes) and should concentrate on any unwetted portions of the container. Apply water from the side and from a safe distance. Cooling should continue until well after the fire is out. If this is not possible, use unmanned monitor nozzles and immediately evacuate the area.
If a leak or spill has not ignited, use water spray in large quantities to disperse the vapours and to protect personnel attempting to stop a leak. Water spray can be used to dilute spills to nonflammable mixtures and flush spills away from ignition sources. Solid streams of water may be ineffective and spread material.
For an advanced or massive fire in a large area, use unmanned hose holders or monitor nozzles; if this is not possible, withdraw from fire area. Withdraw immediately in case of rising sound from venting safety device or any discolouration of tank. Tanks or drums should not be approached directly after they have been involved in a fire, until they have been completely cooled down.

Protection of Fire Fighters:
Ethylene glycol diacetate is slightly hazardous to health. Firefighters may enter the area if positive pressure self-contained breathing apparatus (NIOSH approved or equivalent) and full Bunker Gear is worn.


NFPA - Health: 1 - Exposure would cause significant irritation, but only minor residual injury.
NFPA - Flammability: 2 - Must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
NFPA - Instability: 0 - Normally stable, even under fire conditions, and not reactive with water.

Does not occur.

Incompatibility - Materials to Avoid:

NOTE: Chemical reactions that could result in a hazardous situation (e.g. generation of flammable or toxic chemicals, fire or detonation) are listed here. Many of these reactions can be done safely if specific control measures (e.g. cooling of the reaction) are in place. Although not intended to be complete, an overview of important reactions involving common chemicals is provided to assist in the development of safe work practices.

STRONG OXIDIZING AGENTS (e.g. chromium trioxide, calcium hypochlorite, nitric acid, potassium permanganate, peroxides) - react violently. Can increase the risk of fire and explosion.(6,15)
STRONG ACIDS (e.g. hydrochloric acid and sulfuric acid) and STRONG BASES (e.g. sodium hydroxide and potassium hydroxide) - reaction may be vigorous. Decomposition can occur.(15)
STRONG REDUCING AGENTS (e.g. metal hydrides, such as lithium aluminum hydride) - reaction may be vigorous. Decomposition can occur.(15)

Hazardous Decomposition Products:
Ethylene glycol, acetic acid.

Conditions to Avoid:
Heat (temperatures greater than 88 deg C).

Corrosivity to Metals:
Based on comparison to related compounds, ethylene glycol diacetate is not expected to be corrosive to the common metals, such as steel, stainless steel, aluminum, copper, brass, bronze, nickel, tantalum and titanium.

Corrosivity to Non-Metals:
Based on comparison to related compounds, ethylene glycol diacetate may attack chloroprene, polyurethane, chlorosulfonated polyethylene (CSM), chlorinated polyvinyl chloride (CPVC) and polyvinyl chloride (PVC). Teflon, Viton A and other fluorocarbons, are probably resistant to ethylene glycol diacetate.
