<unk>  (or sulphate) <unk>  or NaDS) (C12H25NaO4S), also known as<unk>  lauryl<unk>  (SLS), is an anionic surfactant that is used in household products such as toothpastes, shampoos, shaving foams and bubble baths for its thickening effect and its ability to create a lather.  The molecule has a tail of 12 carbon atoms, attached to a<unk>  group, giving the molecule the amphiphilic properties required of a detergent.
It is prepared by sulfonation of dodecanol (lauryl alcohol, C12H25OH) followed by neutralization with<unk>  carbonate.  It is used in both industrially produced and home-made cosmetics.
Like all detergent surfactants (including soaps), it removes oils from the skin, and can cause skin irritation. It is also irritating to the eyes.<unk>  can be converted by ethoxylation to<unk>  laureth<unk>  (also called<unk>  lauryl ether<unk> ; SLES), which is less harsh on the skin, probably because it is not as much of a protein denaturant as is the unethoxylated substance.
It is probably the most researched anionic surfactant compound.
It has recently found application as a surfactant in gas hydrate or methane hydrate formation reactions, increasing the rate of formation as much as 700 times.
