Features Of Solvay Cyquest 120 Chelating Agent Surfactant

  1. Combines strong chelation of multivalent metal ions (e.g., Ca²⁺, Mg²⁺, Fe³⁺) with effective anionic surfactant functionality.

  2. Offers excellent stability in hard water and high-ionic-strength formulations without precipitation or loss of performance.

  3. Provides synergistic cleaning, dispersion, and anti-redeposition benefits in alkaline and neutral pH systems.

  4. Biodegradable and formulated to meet stringent environmental and regulatory requirements for industrial cleaners and detergents.

  5. Enables reduced dosage of other additives—such as sequestrants and builders—without compromising formulation efficacy.

Typical Applications Of Solvay Cyquest 120 Chelating Agent Surfactant

  1. Industrial and institutional (I&I) alkaline heavy-duty cleaners for metal parts, tanks, and equipment.

  2. Formulations for CIP (Clean-in-Place) systems in food, beverage, and pharmaceutical processing.

  3. Specialty detergent blends for textile pre-treatment, scouring, and dye house auxiliaries.

  4. Oilfield scale inhibitors and wellbore cleaning fluids requiring simultaneous chelation and surface activity.

  5. Eco-conscious metalworking fluid additives where hardness control and emulsion stability are critical.
