Sodium dodecanoate (sodium laurate) is used in cholloidal chemistry as a nonionic surfactant.
Sodium Laurate is the sodium salt of lauric acid. It functions as a binder, emulsifier, and anticaking agent.
ChEBI: An organic sodium salt resulting from the replacement of the proton from the carboxy group of dodecanoic acid by a sodium ion.
Neutralise it by adding a slight excess of dodecanoic acid and removing it by ether extraction. The salt is recrystallised from the aqueous solution by adding pure Me2CO and repeating the process (see sodium decanoate). It has also been recrystallised from MeOH. [Beilstein 2 IV 1085.]
