Description

Linear Alkylbenzene Sulfonates (LAS) are a class of anionic surfactants derived from the sulfonation of linear alkylbenzenes. These compounds are valued for their excellent detergency, foaming properties, and cost-effectiveness in aqueous systems. They are essential raw materials for manufacturers in the detergent, cleaning, and personal care industries, where consistent performance and reliable supply are critical.

Application

• Household & Industrial Detergents: Primary surfactant in laundry powders, liquids, and dishwashing formulations.
• Personal Care Products: Key foaming and cleansing agent in shampoos, shower gels, and hand soaps.
• Industrial & Institutional (I&I) Cleaners: Used in floor cleaners, hard surface cleaners, and degreasers.
• Emulsion Polymerization: Acts as an emulsifier in the production of synthetic rubbers and polymers like SBR and ABS.
• Textile Processing: Employed as a wetting, scouring, and leveling agent in textile manufacturing.
• Agricultural Formulations: Used as an adjuvant in pesticide and herbicide formulations to enhance spreading and wetting.

Quality Control

Our Linear Alkylbenzene Sulfonates are manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for active matter content, free oil, unsulfonated matter, and color. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong bases and incompatible organic solvents. Typical recommended storage temperature is between 15°C and 25°C. Keep containers tightly sealed when not in use to prevent moisture absorption and maintain product integrity.
