96% LABSA Detergent Raw Material

The appearance of straight-chain alkylbenzenesulfonic acid is a brownish to dark brown viscous oily liquid with a typical mild sulfonic acid odor. Its core value lies in the hydrophobic straight-chain alkyl chains and hydrophilic sulfonic acid groups in its molecular structure. This structure enables it to efficiently reduce surface tension and possess unparalleled cleaning, emulsifying and foaming properties.
