BIO-TERGE AS-40 HASB is Sodium C14-16 Olefin Sulfonate that provides excellent viscosity, foam characteristics, and mildness. It is an ideal anionic surfactant for a variety of household, industrial, and institutional cleaning and personal care applications, as well as agricultural formulations and construction products used for concrete bases, firefighting foams, and dust control. BIO-TERGE AS-40 HASB is preserved with excess alkalinity, which allows the formulator flexibility when choosing a preservative for their finished formulation.
