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.
