Sodium Dodecyl Sulfate
Sodium dodecyl sulfate is a kind of anionic surfactant, which is a typical representative of sulfate surfactants, abbreviated to SDS, also known as as as, K12, sodium cocoitol sulfate, sodium lauryl sulfate and foaming agent. The products sold on the market are usually white to yellowish crystalline powder, non-toxic, slightly soluble in alcohol, insoluble in chloroform and ether, easily soluble in water, complex with anions and non-ionic It has good compatibility, good emulsification, foaming, foaming, permeability, decontamination and dispersion performance, rich foam, rapid biodegradation, but the water solubility is inferior to that of fatty alcohol polyoxyethylene ether sodium sulfate (AES). It is not sensitive to alkali and hard water, but its stability is inferior to that of general sulfonate in acid condition, close to AES, and should not be more than 95 ℃ in long-term heating. The stimulation index of 10% solution is 3.3, higher than AES, lower than sodium dodecylbenzene sulfonate (LAS).
