Talk:Sodium dodecyl sulfate
From Wikipedia, the free encyclopedia
This article says that sodium lauryl sulfate == sodium dodecyl sulfate. The article for sodium laureth sulfate implies that they are different: which is correct?
They are not different.
Sodium laureth sulfate article now fixed. --Heron 09:49, 29 Nov 2004 (UTC)
Better UNfix it, then! The "-eth" ending means one or more ethoxyl units, so it's NOT the same as laurYL. -- robgood@bestweb.net , 12/16/04
Looks like we lost a resource -- http://www.huibers.org/surfactants/ . -- robgood@bestweb.net , 12/18/04
The use of Sodium Laureth Sulfate has been linked to mouth sores or canker sores in many people. http://www.saveyoursmile.com/cankersores/studies.html -- holstein13@hotmail.com, 12/23/04
No, that's lauryl, not laureth. I don't think the ether sulfate is in wide use in toothpastes. -- robgood@bestweb.net , 1/8/05
Should I add a section on ferrofluids? A NASA article says this is the surfactant they use in most of the ferrofluids they work with.DUCK 15:18, 13 April 2006 (UTC)

SDS kills AIDS, herpes, HPV? scharles 18:20, 5 May 2006 (UTC)
- Sulfuric acid kills all those things too. The problem is to find something that kills them but doesn't kill people. —Keenan Pepper 00:10, 6 May 2006 (UTC)
[edit] Safety concerns relating to SLS
Ok. I go to a hippie school, and I appreciate that alot of people are concerned about the possible health risks brought on by SDS. But come on people. This is suppsoed to be an encyclopedia. Try not to reference internet-only articles that reference articles that reference journals. Just find a published piece of research that supports your view. The citations in the "Safety concerns relating to SLS" section need to be updated. I know we can do better people; let's hold the science articles up to a higher standard. -Shaggorama 08:49, 2 October 2006 (UTC)
- at the very least, it should be on the SLS page and not here.
SLS is commonly used as an irritant in medical studies, and the fact that a citation is 20 years old does not invalidate it. An American Journal of Toxicology Report states that "Other studies have indicated that Sodium Lauryl Sulfate enters and maintains residual levels in the heart, the liver, the lungs and the brain from skin contact. This poses question of it being a serious potential health threat to its use in shampoos, cleansers, and tooth pastes." [User: K1lted] 10:30, 23 January 2007 (CET)
[edit] CMC of SDS
Can someone cite the CMC value for SDS? This page says the CMC is 8.4 mM, but people have obtained alternate values using different methods. Example - 3.4 mM when using Capillary Electrophoresis method. http://www.jstage.jst.go.jp/article/analsci/14/2/379/_pdf
[edit] Remove unsourced tag
I have removed the unsourced tag as there are numerous sources cited in this article, if a statement or fact is in question please use the {{fact}} tag so the problem may be specifically addressed many thanks --Matt 10:27, 22 January 2007 (UTC)
