LABSA 96-97% ( Sulfonic Acid ) is the largest-volume synthetic surfactant because of its relatively low cost, good performance, the fact that it can be dried to a stable powder and the biodegradable environmental friendliness as it has straight chain. LABSA 96% is an anionic surfactant with molecules characterized by a hydrophobic and a hydrophilic group. HS code: 34021130 Chemical formula: R-C6H4-SO3H / C₆H₅C_nH_2n+1 Classification: anionic surfactant
