Sodium Secondary Alkyl Sulfonate (CAS 97489-15-1), commercially referred to as SAS 60, is a high-performance anionic surfactant produced via the sulfoxidation of n-paraffins, primarily utilized as a core cleaning agent in liquid laundry detergents, dishwashing liquids, and industrial cleaners. This Sulfonic acids, C14-17-sec-alkane, sodium salts compound functions as a superior wetting agent and grease emulsifier in Secondary alkane sulfonate formulations, offering outstanding solubility and stability over a wide pH range compared to linear alkylbenzene sulfonates (LAS), even in hard water conditions. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

Applications:
Resistant to low and high alkali penetrants.
Refiners resistant to low and high alkalis.
Heavy oil type degreaser and soap detergent.
A system that improves permeability is needed.
Serves as an efficient emulsifier for PVC and SBR latex production, providing small particle size
FAQ - Technical & Supply Chain
-
Q:
How does this surfactant compare to LAS (Linear Alkylbenzene Sulfonate) in formulation?
A: It offers significantly higher water solubility and stronger grease-cutting power at lower temperatures, making it the preferred choice for concentrated liquid detergents where LAS might precipitate or cause viscosity issues. -
