Sodium myreth sulfate 2948513 143579743 2007-07-09T21:00:55Z Chem-awb 4806773 Removed {{ChemicalSources}} as obsolete '''Sodium myreth sulfate''', or '''sodium myristyl ether sulfate''' ('''SMES'''), is a [[detergent]] and [[surfactant]] found in many personal care products ([[soap]]s, [[shampoo]]s, [[toothpaste]] etc.). It is a cheap and very effective [[foaming agent]]. Its [[CAS registry number]] is {{CASREF|CAS=025446-80-4}}. [[Image:Myreth sulfate.png|thumb|300px|right|Chemical structure of sodium myreth sulfate]] Sodium myreth sulfate is very similar to sodium laureth sulfate; the only difference is two more carbons in the [[fatty alcohol]] molecule on the [[hydrophobic]] tail. Both detergents are manufactured by ethoxylation which [[1,4-Dioxane|1,4-dioxane]] may be produced. Its chemical formula is [[carbon|C]][[hydrogen|H]]<sub>3</sub>(CH<sub>2</sub>)<sub>12</sub>CH<sub>2</sub>([[oxygen|O]]CH<sub>2</sub>CH<sub>2</sub>)<sub>n</sub>O[[sulfur|S]]O<sub>3</sub>[[sodium|Na]]. Sometimes the number represented by "n" is specified in the name, as laureth-n sulfate (unsubscripted), for example laureth-2 sulfate. ==Alternative names== * PEG-(1-4) Myristyl Ether Sulfate, sodium salt * POE(2) Myristyl Ether Sulfate * Sodium Diethylene glycol Myristyl Ether Sulfate * Sodium Myristyl Ether Sulfate ==See also== * [[Sodium laureth sulfate]] ==External links== * [http://hpd.nlm.nih.gov/cgi-bin/household/brands?tbl=chem&id=885 Household product database] at NIH web site. * [[Category:Cosmetic chemicals]] [[Category:Ethers]] [[Category:Household chemicals]] [[Category:Organosulfates]] [[Category:Sodium compounds]] [[Category:Surfactants]]
