Linear Alkyl Benzene Sulphonic Acid is a sulfonic acid derivative of linear alkyl benzene, characterized chemically by the formula C18H30O3S and identified under CAS number 85536-14-7. It typically appears as a pale yellow to brown viscous liquid with a strong acidic odor and a pH usually between 0.5 and 1.5 in aqueous solution.
The product’s surfactant action relies on its amphiphilic structure, where the hydrophobic linear alkyl chain attaches to oily soils, and the hydrophilic sulfonic acid group remains water-soluble. This dual affinity lowers surface tension, disperses grease, and emulsifies dirt particles, improving detersive performance in cleaning formulas.
LABSA is manufactured via sulfonation of linear alkyl benzene using sulfur trioxide or oleum, resulting in a high-purity surfactant raw material. Its sulfonic acid contains an acidic proton, making it compatible with neutralization to form sodium linear alkyl benzene sulphonate— a standard anionic surfactant in detergent powders and liquids.
Its stability in aqueous environments, efficient foaming properties, and strong anionic charge contribute to superior soil removal and fabric-friendly washing when formulated correctly. Besides domestic use, LABSA’s role extends into industrial processes such as textile wet processing and leather treatment, where it facilitates cleaning and chemical penetration.
Purchasers must assess key factors like purity levels, acid value, and storage logistics. While purity varies with producer and grade, confirming with the supplier and reviewing certificates of analysis is standard practice. Zenco Systems Ltd emphasizes batch consistency and regional logistical expertise to provide LABSA that meets East African industry standards and operational demands.
