Sodium Dodecyl Sulfate

Catalog DGS151213
CAS 151-21-3
Structure
Description Sodium dodecyl sulfate, synonymously sodium lauryl sulfate (or laurilsulfate; SDS or SLS, respectively), is a synthetic organic compound with the formula CH3(CH2)11SO4Na. It is an anionic surfactant used in many cleaning and hygiene products. The sodium salt is of an organosulfate class of organics. It consists of a 12-carbon tail attached to a sulfate group,[not verified in body] i.e., it is the sodium salt of dodecyl hydrogen sulfate, the ester of dodecyl alcohol and sulfuric acid. Its hydrocarbon tail combined with a polar "headgroup" give the compound amphiphilic properties and so make it useful as a detergent.[not verified in body] Also derived as a component of mixtures produced from inexpensive coconut and palm oils, SDS is a common component of many domestic cleaning, personal hygiene and cosmetic, pharmaceutical, and food products, as well as of industrial and commercial cleaning and product formulations.[not verified in body]
