Properties

Sodium dodecyl sulfate is a kind of anionic surfactant, which belongs to the typical representative of sulfate surfactant. The products sold on the market are usually white to yellowish crystalline powder, non-toxic, slightly soluble in alcohol, insoluble in chloroform and ether, and easily soluble in water. It has good compatibility with anionic and non-ionic surfactants, and has good emulsification, foaming, foaming, permeability, etc However, its water solubility is lower than that of fatty alcohol polyoxyethylene ether sodium sulfate.
