Sodium dodecyl sulfate is a kind of anionic surfactant, belongs to the typical representative of sulfate surfactants, referred to as SDS, also known as AS, K12, sodium cocoate sulfate, sodium lauryl sulfate, foaming agent, marketed commodities are usually white to slightly yellow crystalline powder, non-toxic, slightly soluble in alcohols, and anionic, nonionic compounding compatibility, with good emulsification, foaming, foaming, It has good emulsification, foaming, foaming, penetration, decontamination and dispersion properties, rich foam, there are two kinds of sodium alkylbenzene sulfonate used in detergents, branched structure (ABS) and straight chain structure (LAS), branched structure biodegradability is small, and it will pollute the environment, while the straight chain structure is easy to be biodegradable, and the biodegradability can be more than 90%, and it will pollute the environment to a small extent.

Sodium dodecylbenzene sulfonate is neutral, and its degree of water solubility is second to sodium fatty alcohol polyoxyethylene ether sulfate (AES for short). It is not sensitive to alkali and hard water, but its stability under acidic condition is second to general sulfonate, close to AES, long-term heating should not be more than 95 ℃, irritation belongs to the middle level among surfactants, 10% solution irritation index is 3.3, which is higher than AES and lower than sodium dodecylbenzene sulfonate (LAS for short).
