What is glycol ether used for?
What is glycol ether used for?
Glycol ethers have many uses; these include use as solvents and as an ingredient in cleaning compounds, liquid soaps, and cosmetics. Acute (short-term) exposure to high levels of the glycol ethers in humans results in narcosis, pulmonary edema, and severe liver and kidney damage.
What is polyethylene glycol ether?
Definition. Alkyl polyethylene glycol ether is a cleaning agent, or “surfactant,” that can be found in a variety of household cleaning products. It works by dissolving the residue that remains on bathroom surfaces, such as oils and soaps. It’s particularly good at removing soap scum.
What is fatty alcohol polyglycol ether?
Fatty alcohol polyglycol ethers are nonionic surfactants, prepared by the reaction of fatty alcohols with ethylene oxide or propylene oxide using alkaline catalyst. The degree of ethoxylation can vary depending on the chain length of the fatty acid and the purpose for which it will be used.
What are E-series glycol ethers?
E-Series Glycol Ethers E-Series glycol ethers are ethylene oxide-based, more water soluble, and slightly stronger solvents.
Is glycol ether poisonous?
Most glycol ethers are water-soluble, biodegradable and only a few are considered toxic. One study suggests that occupational exposure to glycol ethers is related to low motile sperm count, a finding disputed by the chemical industry.
How do you avoid glycol ethers?
When using ethylene glycol monomethyl ether, workers should wear chemical safety goggles, and adequate ventilation is necessary. Eye protection is also recommended whenever the possibility of such contact exists with ethylene glycol monobutyl ether. Inhalation of its vapours and skin contact should be avoided.
Is polyethylene glycol safe to inject?
Our results demonstrate that although PEG 200 is generally considered to be harmless, it can be toxic when injected i.p. and is painful for the recipient mice.
What are side effects of polyethylene glycol?
COMMON side effects
- irritation of the rectum.
- a sleep disorder.
- excessive thirst.
- nausea.
- vomiting.
- stomach cramps.
- abdominal bloating.
- a feeling of general discomfort called malaise.
What is Alkoxylation process?
Alkoxylation is a chemical reaction that involves the addition of an epoxide to another compound. The usual manifestation of this reaction is ethoxylation of alcohols (ROH), in which case ethylene oxide is the alkoxylating agent: PO is mainly used for alkoxylation to produce polyether polyols.
What products have glycol ethers?
Mostly, p-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives. On the other hand, e-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water based paints.
What products contains ether?
Endless Uses for Glycol Ethers
- Brake fluids.
- Coating.
- Compounders.
- Cosmetics.
- Dyes.
- Engraving.
- Gypsum.
- Lacquers.
Which is the name of the first glycol ether?
The first one was ethyl cellosolve (ethylene glycol monoethyl ether), with the name now generic for glycol ethers. Glycol ethers are either “e-series” or “p-series” glycol ethers, depending on whether they are made from ethylene oxide or propylene oxide, respectively.
How are ethylene glycol and polyether prepared?
Poly(ethylene glycol) and poly(propylene glycol) with a molecular weight of less than 20,000 g/mol are obtained from the ring-opening polymerization of oxirane and methyloxirane. Poly(tetrahydrofuran) is commonly prepared by acid-catalyzed polymerization of tetrahydrofuran.
Why is polyalkylene glycol monobutyl 150 ether non toxic?
Because polyalkylene glycol monobutyl 150 ether polymeric fluids are water-soluble and non-toxic at low concentrations they are considered 151 environmentally friendly compounds with respect to petroleum based lubricants that are not water 152 soluble.
Which is the best solvent for glycol ether?
Glycol ether solvents Ethylene glycol monomethyl ether (2-methoxyethanol, CH 3OCH 2CH 2OH) Ethylene glycol monoethyl ether (2-ethoxyethanol, CH 3CH 2OCH 2CH 2OH) Ethylene glycol monopropyl ether (2-propoxyethanol, CH 3CH 2CH 2OCH 2CH 2OH) Ethylene glycol monoisopropyl ether (2-isopropoxyethanol, (CH 3) 2CHOCH 2CH 2OH)
