Difference between emulsifiers and surfactants?
This article does not enlighten me as to the difference between "emulsifier" and "surfactant", both of which the article uses, seemingly interchangeably and without comparison. —Preceding unsigned comment added by 72.244.58.246 (talk) 21:54, 12 January 2009 (UTC)

Surfactant is short for "surface active agent", so all emulsifiers are surfactants. However the inverse is not necessarily true. Agents that are good for foaming are also surfactants, but may be poor emulsifiers. In any case, the whole article needs rewriting, so this is the least of our problems.

Photography
There ought to be more info here regarding photographic emulsions and their compositions.
 * I suggest a separate page specifically for photography related emulsions. BTW, see Photo emulsion.  Since this article is on the chemistry of emuslion, I'm going to remove the filmaking tag.  ENeville 20:36, 4 September 2006 (UTC)

"Photographic emulsion is not a true emulsion, but is a suspension of solid particles in a fluid. The word emulsion is established usage in photography and photographic science."--Ingenpedia, Photographic Emulsion. For that reason, I think that the text "the photo-sensitive side of photographic film," should be removed from the introduction of this article, or, alternatively, the reader should be referred to the Photographic Emulsion for that subject. —Preceding unsigned comment added by 216.40.140.5 (talk) 23:41, 28 May 2010 (UTC) ss — Preceding unsigned comment added by 45.115.54.201 (talk) 07:37, 12 November 2020 (UTC)

Else
I understand that there is a need for Emulsion in asphalt road laying. I want to know why? How the emulsion is created? What are th ealternatives. What they did when one such emulsion was not present? How to avoid using the asphalt emulsion and use some environmental friendly emulsion....

"In butter and margarine, a continuous liquid phase surrounds droplets of water (water-in-oil emulsion)." Shouldn't this be "a continuous oil phase"? I came here to read what an emulsion is, so I'm not familiar with these terms, but that would make more sense.

~Oil is not a phase, so "continuous oil phase" would not make sense. Oil is a liquid and thus liquid is the "phase". I hope this makes sense.

- I agree. Oil is not a phase, so, "continuous oil phase" does not make sense. However, the same mistake is made later in the sentance with "continuous water phase". I recommend editing the sentance to the following:

"In butter and margarine, oil surrounds droplets of water (a water-in-oil emulsion). In milk and cream, water surrounds droplets of oil (an oil-in-water emulsion). "

This is simple and gets the point across. -TEDMONDS April 17, 2008

Contamination effect
Dear Sir or Madam,

We are from PT. SOC BATAM (INDONESIA). We would like to request more information for this Emulsifier. Is it hazard for containmation when this chemical Emulsifier were apply at the electricity components. (eg. The handglove make from Emulsifier chemical and we using for screening the electronic components).

We kindly to hear further information.

Thanks and regards


 * Emulsifier is a name for a property of a chemical - like acid or base - and not a particular chemical. You should contact the person you purchased the chemical from for more information. --Einstein9073 05:22, 14 March 2006 (UTC)

Acrylic Polymer Emulsion
"Over time, emulsions tend to revert to the stable state of oil separated from water." I have no idea what acrylic polymer emulsion is, but it is water-based (I think), so it involves no oil (I think): If an organic chemist, or any chemist, OR ANYONE :-), could clear this up I would appreciate it, also it is used in coffee.


 * The See Also section now has a link to Emulsion polymerization, which says that in a polymer emulsion, the monomer is the oil. Indeterminate (talk) 21:20, 22 July 2008 (UTC)

Emulsifier/Surfactant
Emulsifier goes to Emulsion, where it is treated as interchangeable with Surfactant. This is a little confusing. Should Emulsifier be separated, then combined with Surfactant? ENeville 23:16, 1 September 2006 (UTC)

Surfactants and emulsifiers are all serving to decrease the interfacial tension between two different interfaces, whether it be a fluid-fluid interface, air-fluid interface, etc. Surfactants can therefore be used to decrease the interfacial tension between two fluids and allow for them to be emulsified, but this may not be their sole purpose. Quite honestly they can be used interchangeably, it is their intended goal, not their chemical structure nor surface interactions, that classify them as surfactant or emulsifier. — Preceding unsigned comment added by 70.225.179.26 (talk) 03:52, 13 October 2011 (UTC)

Propofol image
When I view the main page, I see the image "code" instead of the image itself - but when I copy it here it seems to work. What's the deal? Jefromi (talk) 22:31, 14 October 2008 (UTC)

Issue with image
The description of the image mentions the surfactant as a "purple outline", yet it is not visible (or at least, barely visible). The image should be edited to enhance the visibility of this outline. Fuzzform (talk) 22:21, 24 November 2008 (UTC)


 * I agree. The outline needs to be made thicker.  --Una Smith (talk) 16:27, 7 March 2009 (UTC)


 * I made the outline about 2x thicker. --İnfoCan (talk) 13:38, 11 March 2009 (UTC)

Conflicting info ?
The text says that nanoemulsions are not yet ready for intravenous injection (due to effect on blood cells), but the picture's caption says this is a nanoemulsion for intravenous injection.

Which is right ? —Preceding unsigned comment added by Plvekamp (talk • contribs) 00:04, 19 May 2009 (UTC)

I figured it out myself with a little research.... The picture is of a regular emulsion, not a nanoemulsion. The text next to the picture is solely about nanoemulsion in medicine, which is a bit misleading to the casual reader. Plvekamp (talk) 00:21, 19 May 2009 (UTC)

Controversy?
Due to the recent Michael Jackson murder trial, I suggest something other than propofol as a pharmacological emulsion. Simply to avoid offending people's sensitivities. — Preceding unsigned comment added by Borninlyoko (talk • contribs) 05:49, 13 October 2011 (UTC)

Examples in the Introduction, and other sections
I worked on this article a bit (having come to it through the "pages with intros too long" tag), and there have been some edits and reversions, so I think it might be appropriate to have a small discussion about examples in this article. There are thousands, probably millions, of emulsions in the world, used for a variety of purposes, I'm just not sure that this article needs to be a place where every single one of them is listed. If you have an example of a specific emulsion's use, or if the example is illustrating a property, then by all means I think they warrant inclusion. IMHO long lists of examples, however, tend to clutter up the article and reduce the readability. If anybody feels otherwise, I'd be open to hearing other thoughts on the subject. Jhfortier (talk) 04:55, 27 October 2009 (UTC)
 * Also, I'm admitting up front that the article is far from perfect right now: there are way too many examples. I think the task is going to be removing the unnecessary ones and keeping the ones that really illustrated emulsions for the average reader Jhfortier (talk) 04:55, 27 October 2009 (UTC)

Needs some copy edit
This sentence needs a lot or work, or could possibly be removed:

"A review article in [1] introduces into various attempts to describe dispersions / emulsions."

"... without a sound scientific basis" (re. stability testing)
The above statement has already been marked as needing citation, but IMO even if it *had* a proper citation it wouldn't be particularly helpful to readers in its current form. It's just sort of a dangling factoid.

My guess is that the person who made that statement had a further point to make - perhaps regarding unreliability of "best before" dates printed on consumer products?

Whatever useful point was about to be made, IMO either that point should be made explicitly, or the paragraph I'm referring to should be deleted, because in its current form it doesn't contribute much at all.

In other words, if the rest of the paragraph would be deleted as off-topic, then get rid of this introductory statement as well. TooManyFingers (talk) 20:24, 21 November 2019 (UTC)

Oops. I should have said that the part I'm talking about is under "Appearance and properties" / "Accelerating methods for shelf life prediction". TooManyFingers (talk) 20:28, 21 November 2019 (UTC)

Should "Emulsifier" be split off?
I think that the "Emulsifier"section should be split off as a separate article. It should duly point out the overlap with other concepts like dispersant, plasticizer, surfactant, and detergent, noting that the differences are largely in the intent of the addition, rather than in the substances or mechanism.--Jorge Stolfi (talk) 23:57, 30 June 2020 (UTC)
