  Dodecyl benzene sulfonic acid Alias:Linear alkylbenzene sulphonic acid,LABSA,DBSA,DDBSA Dodecyl benzenesulfonic acid, Dodecyl benzene sulphonic acid Laurylbenzenesulfonic acid CAS: 27176-87-0 Molecular formula：C18H30O3S（Na） Properties: Appearance: yellow-brown semi-flow of liquid Content: ≥96%±1% Content of unsulfated matter: ≤2% Content of free acid: ≤1.5% Color: ≤ 50 （kleet） Solubility: soluble in cold water and Methanol Applications: In daily chemicals: It is a water soluble anionic surfactant, has good wetting, emulsification, dispersibility, foaming and decontamination ability in hard water, and can be use as detergents such industrial detergent, household liquid detergent and textile cleaner. In dyeing: It is an anionic surfactant, and has excellent penetrability under strong alkali and high temperature conditions, as well as good emulsification, deoiling and cleaning action. It is a ideal raw material for pretreatment agent, and is widely used in de-fatting, de-waxing, degumming and de-oiling of natural fiber such as cotton, ramie, wool and silk. It is penetrating agent and scouring agent in one bath pretreatment in dyeing and finishing, and is common raw material for dispersant, dyeing assistant and oil agent for synthetic fiber. It has good compatibility and synergistic effect with anionic and nonionic surfactants. In mining: Floating agent for separation In oil field: Flooding and foaming. Used as curing catalyst for amino baked paint. Package: 125kg in plastic drum and 200kg in open-head plastic drum. Valid period of 1 year and transport as a common chemical.
