H Padleckas 13:13, 20 July 2005 (UTC)

• Hi, Henri, of course kt/a are thousand tonnes per annum, a very common abbreviation for that part of the world that uses tonnes of 1000 kg. Metric! The UK is going to metric very slowly: when does the US catch up? By the way: Excellent picture.

Delinked

I delinked the following link to ethylene glycol because I think it gives people the impression that this compound is identical to ethylene glycol:

Removed California Toxic Air Contaminants reference

The reference was to California's Hazardous Substances List. EGBE is considered a hazardous substance. That is not the same as the California Toxic Air Contaminants List. Currently EGBE is not considered a toxic air contaminant by either California or the EPA. Sunraven 14:42, 08 December 2008

notable products?

I don't know if it's necessary/warranted or not, but perhaps a list of products that contain this chemical? I was surprised to find that "LA's Totally Awesome" all purpose cleaner contains this chemical. I've used it a while now, and damn, the product does work good....I was kinda curious as to "what" or "how" the product works, since it says contains no acid, bleach, ammonia, etc....right on the bottle, well what's LEFT? lol. In fine print (it's bigger on their website though lol), it says Contains 2-Butoxy ethanol but doesn't give any cautionary information, why this is good/bad/etc....but yes, it's a good cleaner, and the dilution scale is quite high :) 20-1 (1 part LAs Totally Awesome) for some cleaning applications even... Not that it's a bad thing, I haven't experienced any of the side effects listed here, and like I said, I use it weekly, for my house cleaning tasks, it comes cheap, $1 at my local dollar store --72.188.76.225 (talk) 03:48, 10 May 2009 (UTC)

Butyl Cellosolve ubiquitous trade name, should redirect to this article

"Butyl Cellosolve" is much better know and more searched than the chemical name. Findable.

"Butyl Celosolve" is a common misspelling, which should also redirect here.

2-Butoxyethanol use in Hydraulic Fracturing

Please refer to page 7 of this attachment of the congressional report on "CHEMICALS USED IN HYDRAULIC FRACTURING". http://democrats.energycommerce.house.gov/sites/default/files/documents/Hydraulic-Fracturing-Chemicals-2011-4-18.pdf — Preceding unsigned comment added by 24.187.208.114 (talk) 10:31, 25 September 2013 (UTC)

Plan for updating article

For the 2-butoxyethanol page, we would like to begin by expanding on production and uses. In particular, we would like to include more information on the involvement on 2-butoxyethanol in fracking. We would like to clarify the conflicting reports on the carcinogenic properties of 2-butoxyethanol, in addition to supplying more general health information. We would like to expand on the effects that it has on humans and other animals. The environment effects section is currently minimal, so we would like to expand on how it moves through the environment. In particular, its solubility in water, air, and soil and how that affects where it exists. Comparison of different measurements of 2-butoxyethanol in the environment will also be included. Our plan is to keep the general format and content of the article, and to simply expand upon relevant information.

Peer Reviews

Intro:

• I don’t really get a sense of what the chemical does until the last sentence of the intro, so add that it’s a solvent in the first sentence. Maybe also mention some of the main things it’s used in, which would definitely generate interest for the rest of the article. I would also add something about it being a carcinogen
  

Production:

• change “the main routes” to something like “to yield/produce 2-butoxyethanol”…or maybe switch sentence to make butanol and ethylene oxide the subjects.
  

Uses:

• I like the background on glycol ethers. Is 2-buto in the E series or P series?
  
• It seems like the second paragraph that begins with “In 2006” would fit better under the production heading
  
• I’m unsure as to what an indirect food additive is…either wikilink or explain this
  
• “When liquid is pumped into the well, 2-Butoxyethanol is used to stabilize the fracturing fluids that are being pumped under extreme pressure by lowering the surface tension and to facilitate release of the oil by preventing congealing” this sentence is too long and complex, and needs verb agreement between “lowering” and “to facilitate”
  
• It might be useful to split this up into subheadings by industry
  

Safety:

• you should combine “environmental fate” with “disposal and degradation,” as they convey the same message
  
• I would put regulation after animal studies, because human exposure and animal studies are more logically linked
  

Intro:

• This paragraph seems contradictory in saying that it’s not a carcinogen in humans and is not reported as such, but should be handled with extreme caution
  
• Most of this info would fit better under animal studies. Perhaps the first paragraph should just convey that it is a possible carcinogen, and has been tested in rats and humans.
  

Human Exposure:

• the phrase “odor threshold” is confusing. Does this mean that if you can smell it, you are definitely above the threshold for exposure?
  

regulation in Canada:

• “these products are not required..” these doesn’t have an antecedent
  
• what point of dilution is needed to be legally unreported?
  
• “The safety of the products as normally used” – confusing. Does this mean these groups defend its use, and oppose the concerns of the CEPA?
  

Animal Studies:

• I don’t know what Fischer 344 rats are. Is this detail significant in the study?
  
• This is a really clear paragraph that flows well
  

Overall:

• make sure to use either 2-butoxyethanol or simply butoxyethanol the entire time, because the switching in the middle of the article gave me the impression you were talking about different molecules
  
• I am still left with some questions: what specific level are you using to designate high, moderate, and low levels? As a consumer using many of these products, is the level of exposure on a daily basis possibly damaging?
  
• consolidate your references by using < ref name= “author”/ > to eliminate redundancies
  
• A really well written article! The writing was very clear and it was packed with information. Great job! My corrections were knit-picky and a matter of opinion, so change things as you think…you’re the experts. ☺

MADE EDITS THROUGHOUT THE ARTICLE, THAT IS WHY IT IS PASTED BELOW.

2-Butoxyethanol is an organic compound whose molecular formula BuOC₂H₄OH (Bu = CH₃CH₂CH₂CH₂)classifies it as a butyl ether. This colorless liquid has a sweet, ether-like odor as it derives from the family of glycol ethers, such as ethylene glycol. As a relatively nonvolatile, inexpensive solvent it is used in many domestic and industrial products.

Peer Review 3

This article contains a lot of information about what 2-Butoxyethanol is used in and regulations put in place to limit the amount of the chemical in the environment. It is well organized but it feels like it's missing some information. The introduction doesn't really explain what the chemical does, just what it is. In order to have a better idea about how it is harmful to humans/the environment there might want to be some mention of what the role 2-Butoxyethanol plays in the products in which it is found. There is also not a lot of information about the effects that it has on humans. While it is difficult to find studies about human exposure to chemicals, it would be interesting to hear if there is any crossover between what happens to animals and humans when they are exposed to the chemical. It is clear that there are high levels of exposure found in industrial settings and that exposure does cause respiratory issues among other things, but how does the chemical cause those problems? Aukere (talk) 00:49, 3 February 2015 (UTC)

I thought this article was both really informative and well-organized! One area that I think would be interesting to elaborate more on is the use of 2-Butoxyethanol as a direct/indirect food additive. It is mentioned twice in the article, but gives relatively brief parallel information both times. Tiernestep (talk) 00:30, 3 February 2015 (UTC)

Production

2-butoxyethanol is commonly obtained through two processes; the ethoxylation reaction of butanol and ethylene oxide in the presence of the catalyst

C₂H₄O + C₄H₉OH → C₄H₉OC₂H₄OH

or the etherification of butanol with 2-chloroethanol.<ref name=HHS>{{cite book|title=Toxicological Profile for 2-Butoxyethanol and 2-butoxyethanol acetate|date=August 1998|publisher=U.S. Dept of Health and Human Services|author=Harris O., et al}}</ref>

Uses

2-Butoxyethanol has modest surfactant properties. Glycol ethers have been used since the 1930s dissolve both water soluble and hydrophobic substances. Glycol ethers are also comprised of an alcohol from either the ethylene (E) series or the propylene (P) series. Glycol ethers are selected for specific purposes, such as solubility, inflammability, and volatility.<ref>{{cite web|last=Elskamp|first=Carl J.|title=2-Butoxyethanol (Butyl Cellosolve) & 2-Butoxyethyl Acetate (Butyl Cellosolve Acetate)|url=https://www.osha.gov/dts/sltc/methods/organic/org083/org083.html|publisher=United States Department of Labor}}</ref> In 2006, the European production of butyl glycol ethers amounted to 181 kilotons, of which approximately 50% (90 kt/a) was 2-butoxyethanol.

2-Butoxyethanol was introduced into the industrial industry as a solvent for paints and surface coatings, as well as cleaning products and inks. Other products that contain 2-butoxyethanol include acrylic resin formulations, asphalt release agents, firefighting foam, leather protectors, oil spill dispersants, degreaser applications, photographic strip solutions, whiteboard cleaners, liquid soaps, cosmetics, dry cleaning solutions, lacquers, varnishes, herbicides, latex paints, enamels, printing paste, varnish removers, and silicone caulk.

Disposal and degradation

2-Butoxyethanol can be eliminated by incineration. While it usually decomposes in the presence of air within a few days when reacting with oxygen radicals <ref>Hullar, T.; Anastasio, C. Yields of hydrogen peroxide from the reaction of hydroxyl radical with organic compounds in solution and ice. Atmospheric Chemistry and Physics, 11, 7209.</ref> , disposal occurs faster in the presence of semiconductor particles.<ref name=HHS/> As there is no evidence to suggest it as a major environmental contaminant, nor is it known to bio-accumulate, it seems to be fairly manageable. <ref>[http://www.atsdr.cdc.gov/toxfaqs/tf.asp?id=346&tid=61 Agency for Toxic Substances and Disease Registry ToxFAQs]</ref>

Human exposure

Moderate respiratory exposure to 2-butoxyethanol often results in irritation of mucous membranes of the eyes, nose and throat.

Animal studies

Potentially harmful effects have been observed in animals exposed to high levels of 2-butoxyethanol. One study exposing pregnant Fischer 344 rats and New Zealand white rabbits to varying doses of 2-butoxyethanol revealed lasting developmental effects A statistically significant increases in skeletal defects were detected in litters treated with 100 ppm (483 mg/m³) and 200 ppm (966 mg/m³). Additionally, 2-butoxyethanol was associated with a significant decrease in maternal body weight, uterine weight, and number of total implants.<nowiki><ref>Wess, Ms. J., Dr. H.

Neurological effects were identified in one study involving 344 rats tested with 2-butoxyethanol at concentrations of 523 ppm and 867 ppm. Both female and male rats experienced decreased coordination after exposure. Similarly male rabbits in another study exhibited a loss of coordination and equilibrium when given a dose of 400 ppm 2-butoxyethanol for 2 days.<ref>United States of America.

Both F344/N rats and B63F1 mice showed negative effects after 2-butoxyethanol in their drinking water. The range of exposure for the two species was between 70 mg/kg body weight per day to 1300 mg/kg body weight per day. Decreased body weight and water consumption were seen for both species. Rats had reduced red blood cell counts and thymus weights, as well as lesions in the liver, spleen, and bone marrow.<ref>Wess, Ms. J., Dr. H. Ahlers, and Dr. S Dobson.

Some modifications that I made throughout the page include:

• Replacing sentences that begin with “It”

• Combining short sentences

• Eliminating repetition

• Keep in mind to use an active voice, not a passive voice. Clearer and to the point in some cases. Passive voice with controversial points.

Uses:

• 18% for metals production or a metal cleaner?

• Facilities for sterilizing and cleaning=sterilizing and cleaning facilities or = used to sterilize and clean at facilities?

Safety

• Observed “mechanism” (right word?/slightly confusing)

• OSHA does not regulate 2-butoxyethanol as a carcinogen.[citation needed]

Disposal

• Semiconductor particles-link

Human Exposure

• Odor threshold of 0.4ppm, what is that?

I read through your article and found that it was well done. I made edits throughout in this version where I thought that they could prove helpful although you are free to take or leave any input here. I tried to be as constructive as possible in my criticism. I would find another way to mention the example studies instead of by author as the average reader would care less about what some random scientist says. If he or she has a specific title, then mention it; if not, then make it more general: “A study or one study.” That draws more attention to the study rather than unknown researchers. There was a good overall flow and it was relatively clear although there were some parts where I was a littler uncertain as to what was being referenced. The citations seem to be in check, aside from one or two spots where it was shown to be needed already. (Wess, J.; Ahlers, H.; Dobson, S. (1998). Concise International Chemical Assessment Document 10: 2-Butoxyethanol. Geneva: World Health Organization.) was cited 2 or 3 times in the reference section. Find a way so that your multiple in-text citations for the same source refer to the same one in your reference list. This article appears to be pretty neutral as far as just stating the facts but the end seems to favor the side that it is harmful. Show evidence from both sides of the studies or at least take a more passive stance when revealing conclusions. You have a lot of great headings, but look to make your leading sentence more interesting. It seemed a little repetitive at first and it could have been worded better. Add some more general information Looks to have a fair amount of information added though, so good work! I especially like the USES section. Maybe work to expand the global opinions on this chemical, since only Canada and the US are mentioned. Make it more international. Overall, again well done and I hope some of this was helpful.

Dear WlfSprtd23: What qualifies you to state "I read through your article and found that it was well done." ? Do you publish in this area?--Smokefoot (talk) 14:30, 11 April 2014 (UTC)

Edits Made After Peer Reviews

The edits made are as follows:

• Reworked the intro to not start sentences with "it"
• Reworked the production section in order to make it sound better
• Moved the paragraph on production in the "Uses" section to the "Production" section
• Added clarity to a few confusing sentences in the "Uses" section, as suggested
• Split the "Uses" section into subheadings by industry for more organization
• Made sure that the in-text citations that referred to the same source were directed to one source in the "References" section
• Added a link to the odor detection threshold wikipedia page in order to avoid confusion about the definition of that term
• Reworded the "Regulation in Canda" section to avoid confusing wording and lack of antecedents for pronouns
• Added a link to the "laboratory rats" wikipedia page after mentioning Fisher 344 rats in the animal studies section, in order to avoid confusion
• Removed the "environmental fate" since it was a repeat from "disposal" section
• Changed the order of the animal studies and regulation sections to make more sense, as suggested
• Found a citation for the sentence on OSHA not regulating 2-butoxyethanol.

The edits that were not made:

Didn't define .4ppm in the Human exposure section, Schedule 1 in the Regulation in Canda section and didn't change the use of Ty et al. and Dodd et al. in the Animal Studies section. We believe that these are very common terms and don't need to be defined or changed.

=classmate comment February 2015=

Hello, I am a student enrolled in course Environmental Disruptors/Development at BC. As an assignment, we are going around leaving some comments in articles that were worked on in previous courses. ◌For Human Exposure section I found some related information that could have been included and expand the section. That most people start to smell the chemical in air at 0.10-0.40 ppm which is 500 times lower than the present standard for worker exposure. <ref>http://www.atsdr.cdc.gov/phs/phs.asp?id=345&tid=61</ref> Including that household cleaners like varnishes, lacquers, latex paints as common source of the chemical in this section might help the readers grasp the info that they need quicker. But I am aware that you included such information up on "commercial uses" section. More information on how it enters and leaves one's body might be useful. That the exposure is less likely through eating or drinking but more from breathing in air (through the lung)-also the fact that wearing protective clothing decreases the entrance through skin. The reaminder of butoxyethanol enters the bloodstream possibly causing being converted into metabolites in the liver. If you want more information visit http://www.atsdr.cdc.gov/phs/phs.asp?id=345&tid=61 Thank you for all your work! Jukaredaa (talk) 06:24, 3 February 2015 (UTC)

Please use good sources: published reviews and textbooks. Avoid Google searching! You are welcome to ask for advice! This article is a mature one, and it would be surprising if a nonexpert could make major contributions. Good luck.--Smokefoot (talk) 14:43, 3 February 2015 (UTC)

Hazard classification

The page currently lists the GHS classification of this material as:

H227, H302, H311, H315, H319, H330, H336, H361, H370, H372

This does match the description of the text which claims a "Low acute toxicity" and also does not match the harmonised classification or the ECHA dossier for the material, which classifies it as:

H302, H312, H315, H319, H332, Signal word: WARNING (GHS07)

The classification that is currently used in the page is similar to 2-methoxyethanol and 2-ethoxyethanol, it makes sense that either one of these classifications was used in error or the SDS used to derive the given classification was for a product containing material of a more severe classification.

If people agree with this assessment then I will happily make the modifications to the page. — Preceding unsigned comment added by 151.249.75.66 (talk) 10:24, 29 August 2017 (UTC)
