Description

Linear Alkyl Benzenesulphonate (LABS) is a high-performance anionic surfactant derived from linear alkyl benzene, serving as a critical raw material for the production of biodegradable detergents. Its primary value lies in its excellent foaming, wetting, and emulsifying properties, coupled with favorable environmental degradation profiles compared to branched analogues. This compound is essential for manufacturers in the household & industrial cleaning, personal care, and textile processing industries seeking effective and responsible formulation ingredients.

Application

• Primary Surfactant in Detergent Powders and Liquids: The core active ingredient in laundry detergents, dishwashing liquids, and all-purpose cleaners.
• Industrial & Institutional (I&I) Cleaners: Used in formulations for floor cleaners, degreasers, and vehicle wash products.
• Personal Care Products: A key component in shampoos, shower gels, and hand soaps for its effective cleansing and lather.
• Textile Auxiliary: Functions as a wetting agent, scouring agent, and emulsifier in textile pretreatment and dyeing processes.
• Emulsion Polymerization: Acts as an emulsifier in the production of synthetic rubbers, plastics, and latex paints.
• Agricultural Adjuvants: Used in pesticide and herbicide formulations to enhance spreading and wetting on plant surfaces.

Quality Control

Our Linear Alkyl Benzenesulphonate is produced under stringent quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through parameters including active matter content, alkyl chain distribution, and biodegradability. A Certificate of Analysis (COA) detailing specific lot results is provided with every shipment, confirming compliance with agreed specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept sealed when not in use to prevent absorption of atmospheric moisture, which can affect handling and performance properties.
