Description

Ammonium Sulfobetaine-4, Tech., 85 is a high-purity technical-grade zwitterionic surfactant. This compound is valued for its excellent amphoteric properties, providing robust stability and compatibility across a wide pH range. It is a critical raw material for formulators in the personal care, industrial cleaning, and oilfield chemical sectors seeking high-performance, mild surfactants.

Application

• Primary surfactant or co-surfactant in mild personal care formulations such as shampoos, body washes, and facial cleansers.
• Key ingredient in industrial and institutional (I&I) cleaning products for its hard surface cleaning and foam stabilization properties.
• Utilized in oilfield chemicals as a corrosion inhibitor and surfactant for enhanced oil recovery (EOR) applications.
• Component in textile processing aids for leveling, softening, and antistatic purposes.
• Used in the formulation of paints and coatings as a dispersing and wetting agent.
• Applicable in agricultural adjuvants to improve the spreading and sticking of pesticide formulations.
