Toxicol Ind Health. Linear alkylbenzene sulfonate (LAS) is added to cutting fluid formulations to enhance the performance of metal machining operations, but this surfactant can cause contact dermatitis in workers involved in these operations. In 1995, a solid catalyst system (the DETAL process) became available. calcium alkyl benzene sulfonate sharing sensitive information, make sure youre on a federal 2003 Aug;47(6):441-59. doi: 10.1093/annhyg/meg057. !. ]VAx Would you like email updates of new search results? LAS was more likely to partition into the stratum corneum (SC) in mineral oil mixtures, and LAS absorption was significantly greater in the complete mixture. Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate (LAS), a biodegradable surfactant. Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C12-C15, C12-C13 and C10-C13, for detergent use. [3], Given the large scale applications of LAB-derived detergents, a variety routes have been developed to produce linear alkylbenzenes:[3]. LAB was therefore de-classified and was removed from Annex 1 in the 28th ATP (Directive 2001/59). labsa alkyl linear benzene msds pdf author facility acid %%EOF The life-cycle analysis considered the emissions and resulting environmental and human exposures. Unable to load your collection due to an error, Unable to load your delegates due to an error. TRI enhanced LAS transport, and the presence of SRA decreased LAS critical micelle concentration (CMC) which reduced LAS monomers available for transport. LAB has been subject to concern about its effect on the environment and human health.

Cutan Ocul Toxicol. Disclaimer, National Library of Medicine alkyl benzene acid labsa sulfonic The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. There is no need for further testing or risk reduction measures beyond those currently practiced. [1] The CnH2n+1 chain is unbranched. 2005 Oct;21(9):197-205. doi: 10.1191/0748233705th229oa. Linear alkylbenzene 07/08-S7 Report, ChemSystems, February 2009. labsa alkyl benzene sulphonic This process accounts for the majority of the installed LAB production in the world. European Council Regulation (EC) 1488/94[10] led to it being extensively evaluated. Hydrogen fluoride (HF) and aluminium chloride (AlCl3) are the two major catalysts for the alkylation of benzene with linear mono-olefins. benzene sulphonic sodium lauryl dodecyl Each process generates LAB products with distinct features. LAS replaced branched dodecylbenzene sulfonates, which were phased out because they biodegrade more slowly. Clipboard, Search History, and several other advanced features are temporarily unavailable.
