Decyldimethyloctylammonium chloride

Decyldimethyloctylammonium chloride (CAS 32426-11-2 ), also known commercially as Quaternium-24, is a quaternary ammonium compound used as a biocidal active and conditioning surfactant across personal care, cleaning, and industrial applications. Its cationic charge drives both antimicrobial performance and surface substantivity, making it a functional ingredient where dual-action formulation efficiency matters. In home care and institutional cleaning products, it delivers broad-spectrum bactericidal activity. It provides fungicidal activity in surface disinfectants, sanitizing sprays, and hard-surface cleaners. Personal care formulators incorporate it into rinse-off and leave-on products, particularly conditioning treatments and scalp-care formulations. In these applications, antimicrobial preservation and hair substantivity are required simultaneously. Water treatment applications leverage its biocidal properties to control microbial growth in industrial cooling systems and process water circuits. It also appears in industrial disinfectant concentrates where compatibility with other quaternary ammonium actives allows blended formulations to meet broader efficacy standards. This versatility makes it a staple in chemical manufacturing. Decyldimethyloctylammonium chloride is typically supplied as an aqueous solution, with active content concentrations commonly ranging around 50% or 80%. Technical and industrial grades are the standard market offering for most buyers. Cosmetic-grade material is available for personal care applications requiring specific purity. Packaging options generally include drums and IBCs to support both formulation-scale and bulk procurement needs for global distribution.
