Linear Alkyl Benzene Sulphonic Acid is synthesized by sulfonating linear alkyl benzene (LAB), producing a sulfonic acid group attached to the aromatic ring. This chemistry provides LABSA with its characteristic anionic surfactant properties: the hydrophobic linear alkyl chain associates with oils and greases, while the hydrophilic sulfonic acid group ensures water solubility. The result is an ability to reduce surface tension and disperse hydrophobic contaminants into aqueous solutions for easy removal.
This surfactant operates effectively in low pH environments, generally exhibiting a pH range between 2 and 3 in aqueous solution, which helps maintain stability and prevent unwanted side reactions during formulation. Physically, LABSA appears as a viscous liquid ranging in color from pale yellow to brown, reflecting batch variations and purity levels. Its viscosity facilitates dosing in industrial processes, especially in liquid detergent production.
In performance terms, LABSA offers high foaming capacity and exceptional detergency. Its linear alkyl group reduces biodegradation resistance compared to branched equivalents, promoting environmental compliance. It's compatible with other detergent ingredients such as builders, bleaching agents, and additional surfactants. However, care must be taken with formulation pH and storage conditions to prevent acid hydrolysis or phase separation.
Procurement decisions should consider LABSA's purity and grade—these parameters influence product consistency and compatibility with specific detergent formulations. While Zenco Systems Ltd provides verified product specifications on request, confirming these details with supplier certificates ensures alignment with product requirements. The chemical’s CAS number 85536-14-7 and formula C6H4SO3H-C12H25 uniquely identify it within industrial chemical databases.
