Linear Alkylbenzene Sulfonates and Related Compounds - Environmental Health Criteria 169

Linear alkylbenzene sulfonates (LAS), a-olefin sulfonates (AOS), and alkyl sulfates (AS) are anionic sulfonates with molecules characterized by a hydrophobic and a hydrophilic (polar) group. Commercial mixtures Consist of isomers and homologues of related compounds, which differ in physicochemical properties, resulting in formulations for various applications.
