Products Description
Dodecylbenzenesulfonic Acid Sodium Salt, commonly known as SDBS or LAS, has CAS 25155-30-0 and molecular formula C₁₈H₂₉NaO₃S. It is a typical anionic surfactant, appearing as white to light yellow powder, flakes or liquid. It dissolves easily in water and forms translucent aqueous solution. It maintains stable performance in dilute acid and alkali environments. Linear LAS enjoys high biodegradability. We provide different active contents to satisfy laundry, industrial cleaning and textile auxiliary formulations. It is non-dangerous goods for shipment, usually packed in 25kg woven bags or 200kg plastic drums, widely exported to daily chemical manufacturers.

Product Application
It is a core raw surfactant for laundry powder, liquid detergent, dishwashing liquid and all-purpose household cleaners. It works as scouring agent, wetting agent and dye auxiliary in textile and leather processing to boost penetration and uniform dyeing. It serves as emulsifier for emulsion polymerization, dispersant for agrochemical formulations and degreasing agent for metal pretreatment. It can also act as deinking agent in paper recycling and antistatic additive for plastic and fiber products. Different grades are supplied to balance cleaning power, foam performance and formulation cost for household and industrial cleaning systems.
