'''Sodium lauryl sulfate''' (or ''Sodium dodecyl sulfate'') is a [[detergent]] and surfuctant which is commonly used in a wide variety of cleaning products. It also makes substances "foam up" which is another reason it is sometimes used.
'''Sodium lauryl sulfate''' (or ''Sodium dodecyl sulfate'') is a [[detergent]], surfuctant, and foaming agent which is commonly used in a wide variety of cleaning products. It is composed of [[sulfuric acid]], monododecyl ester, and [[sodium chloride]] (table salt).<ref>http://www.wisegeek.org/what-is-sodium-lauryl-sulfate.htm</ref> Since it causes skin irritation, it is often ethoxylated (by adding ethylene oxide) to reduce this effect. This results in the similar chemical '''Sodium laureth sulfate'''.

As a cleaning agent, this is effective at penetrating and removing oils. It also helps its solution to spread across a surface. It is commonly added to soaps (especially liquid soap), shampoos, detergents, toothpastes, and mouthwashes.

It is commonly added to liquid soaps, shampoos, detergents, toothpastes, mouthwashes, hair color and bleaching agents, body washes and cleansers, make-up foundations, laundry detergents, bath oils/bath salts, stain removers, carpet cleaners, fabric glues, shaving creams, and mascara.<ref name="mercola.com">http://articles.mercola.com/sites/articles/archive/2010/07/13/sodium-lauryl-sulfate.aspx</ref>

There are a number of health concerns regarding sodium lauryl sulfate. So far, the only scientifically proven problems it causes are skin irritation,<ref>http://content.karger.com/Article/Abstract/84139</ref><ref>http://slsfree.net</ref> desquamation of oral epithelium (shedding or oral tissue),<ref>http://www.sciencedirect.com/science/article/pii/S0378427497000222</ref> and increased frequency of aphthous ulcers (canker sores).<ref>http://www.crowndiamond.net/techpack/0535.pdf</ref><br />
Some argue that sodium lauryl sulfate is not a risk as much from a large, brief exposure (such as in laboratory experiments) but rather a small but continued exposure.<ref>http://articles.mercola.com/sites/articles/archive/2010/07/13/sodium-lauryl-sulfate.aspx</ref> Problems cause by this kind of risk are hard to track down, and even harder to test in a laboratory.<br />
A common claim against sodium lauryl sulfate is that it is carcinogenic (cancer causing). This has not been scientifically proven, but testing in this area has been minimal. However, when ethylene oxide is added to reduce its irritative properties, the resulting sodium laureth sulfate is suspected to be carcinogenic. The ethylene oxide itself is a carcinogenic substance. Additionally, the ethoxylation process produces the byproduct 1,4 dioxane. This is recognized by the CDC to be "probably carcinogenic to humans," toxic to the brain and central nervous system, kidneys, and liver. As if this were not enough, 1,4 dioxane is also a leading groundwater contaminant.<ref name="mercola.com">http://articles.mercola.com/sites/articles/archive/2010/07/13/sodium-lauryl-sulfate.aspx</ref>
