Is triethylene glycol a hazardous material?

Is triethylene glycol a hazardous material?

Potential Acute Health Effects: Very hazardous in case of eye contact (irritant), of ingestion. Slightly hazardous in case of inhalation. Inflammation of the eye is characterized by redness, watering, and itching. Potential Chronic Health Effects: Very hazardous in case of eye contact (irritant).

What is the use of triethylene glycol?

It is used as a dehydrating agent for natural gas processing; as a lubricating and finishing agent for textiles; a constituent in brake fluids, lubricants, antifreeze formulations, wallpaper strippers and in artificial fog solutions; a solvent for printing inks and textile dyes; and is used as an intermediate in the …

Is triethylene glycol a carcinogen?

There are no data available of the carcinogenicity of triethylene glycol. The acute toxicity of triethylene glycol after inhalation exposure is low (see Table 1). In studies carried out according to present-day standards, the LC50 was greater than 5000 mg/m3.

Is TEG toxic?

Triethylene glycol (TEG) is a liquid industrial chemical with a potential for human exposure. The likelihood for developmental toxicity was investigated in two species.

Is triethylene glycol safe to breathe?

ROUTES OF EXPOSURE: Systemic ethylene glycol toxicity can occur through ingestion. Breathing ethylene glycol vapors may irritate eyes and lungs but is unlikely to cause systemic toxicity. Ethylene glycol does not absorb well through the skin so systemic toxicity is unlikely.

Is triethylene glycol reactive?

TRIETHYLENE GLYCOL is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water.

What is triethylene glycol made from?

How is it produced? Triethylene glycol is prepared commercially as a co-product of the oxidation of ethylene at high temperature, in the presence of a silver oxide catalyst. The ethylene oxide is then hydrated to yield mono, di, tri, and tetra ethylene glycols.

What is difference between triethylene glycol and ethylene glycol?

Triethylene glycol is a poly(ethylene glycol) that is octane-1,8-diol in which the carbon atoms at positions 3 and 6 have been replaced by oxygen atoms. It has a role as a plasticiser. It is a poly(ethylene glycol), a diol and a primary alcohol.

Is triethylene glycol safe to inhale?

Breathing ethylene glycol vapors may irritate eyes and lungs but is unlikely to cause systemic toxicity. Ethylene glycol does not absorb well through the skin so systemic toxicity is unlikely. Eye exposure may lead to local adverse health effects but is unlikely to result in systemic toxicity.

Is triethylene glycol safe for skin?

Based on its consideration of the available information, the CIR Expert Panel concluded that Triethylene Glycol and PEG-4 are safe as cosmetic ingredients in the present practices and concentrations of use as described in this safety assessment.

How do you remove triethylene glycol?

the Ethylene glycol should dissolve in water, and can be separated. There are also reports that Ethylene glycol forms azeotrop with Water -Ethanol mixtures. You can try this method too to remove trace amounts of EG in a rotavap (may need to repeat).

How is triethylene glycol made?

What is the treatment for ethylene glycol?

Treatment should not be delayed pending results of ethylene glycol serum levels if the patient’s condition or history suggests such poisoning. Treatment advice can be obtained from a regional poison control center or medical specialists such as the following with expertise and experience treating patients exposed to ethylene glycol:

Why is glycerol heavier than ethylene glycol?

Glycerol (1,2,3-trihydroxypropane) has three -OH groups per molecule while ethylene glycol (1,2-dihydroxyethane) has two -OH groups. The viscosity depends on the amount of hydrogen bonding between molecules, and the more -OH bonds there are, the more hydrogen bonding can occur.

Is triethylene glycol hazardous?

Triethylene glycol is heated to a high temperature and put through a condensing system, which removes the water as waste and reclaims the TEG for continuous reuse within the system. The waste TEG produced by this process has been found to contain enough benzene to be classified as hazardous waste (benzene concentration greater than 0.5 mg/L).

What are GHS safety data sheets?

Safety data sheets (SDS) are a critically important part of the GHS and global chemical safety. They provide extensive information on a substance, its supplier and the safe handling and use of it. You are then able to conduct chemical risk assessments around your workplace and ensure that each area is safe for work.
