Linear alkylbenzene is a family of organic compounds with the formula C6H5CnH2n+1. 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. The CnH2n+1 chain is unbranched. They are sometimes called LABs. They are mainly produced as intermediate in the production of surfactants, for use in detergent.
