Characteristics and environmental fate of the anionic surfactant sodium

Sodium lauryl ether sulphate or laureth sulphate (SLES) is a sodium salt produced through the ethoxylation of the AS sodium lauryl sulphate (SLS) (Cserhàti et al., 2002). This generates an ethoxylate, which is transformed into a half ester of sulphuric acid and neutralized to achieve SLES.Web

Sodium laureth sulfate

Ether refers to one or more ethylene oxide groups placed between the sulfate and lauryl moieties. So SLES is an oligomer that contains a few ethylene oxide linkages; the mean quantity is about 3, as shown in the 3-D image. SLES is the most common of a group of commercial sodium and ammonium alkyl and alkyl ether sulfates.Web

However you can get your ether very water-poor by drying it over sodium sulphate or magnesium sulphate. Truely dry ether can only be obtained by rigorous drying (e.g. sodium) and subsequent destillation; to be stored under inert gas. Luckily, most suppliers sell dry solvents over molecular sieve with water contents less than 50 ppm.Web
