Description

Linearalkylbenzenesulphonate(C18) CAS NO 27177-79-3 is a high-purity, long-chain anionic surfactant belonging to the linear alkylbenzene sulfonate (LAS) family. It is valued for its excellent detergency, foaming properties, and superior biodegradability compared to branched-chain analogues. This product is essential for formulators in the industrial and institutional cleaning, personal care, and textile processing sectors seeking effective and environmentally responsible surfactant solutions.

Application

• Industrial & Institutional (I&I) Cleaners: A primary active ingredient in heavy-duty liquid and powder detergents for floor cleaners, degreasers, and vehicle wash formulations.
• Household Detergents: Used in the production of high-performance laundry powders, liquids, and dishwashing detergents.
• Personal Care Products: Serves as a foaming and cleansing agent in shampoos, body washes, and hand soaps.
• Textile Processing: Acts as a wetting agent, scouring aid, and emulsifier in fabric preparation and dyeing processes.
• Agricultural Adjuvants: Employed as a component in pesticide and herbicide formulations to enhance spreading and wetting on plant surfaces.
• Emulsion Polymerization: Functions as an anionic emulsifier in the synthesis of polymers like styrene-butadiene rubber (SBR) and acrylics.
