Novel Polymeric Dispersants for Aqueous Suspension Concentrate Formulations

Source

Styrene-acrylic copolymer surfactants demonstrate significant dispersant erformance advantages in suspension concentrate formulations versus current industry standards. The formulation requirement of dispersant to maintain the active ingredient in suspension upon dilution was significantly lower with styrene-acrylic dispersants Atlox® Metasperse 100L or Atlox® Metasperse 500L than with other commercially available anionic surfactants.

When blended with Atlas® G5000 and Synperonic® A7 nonionic surfactants, low viscosity suspension concentrate formulations can be developed using either Atlox® Metasperse 100L or Atlox® Metasperse 500L. Equally important is the use of experimental design techniques to monitor how subtle changes in surfactant ratio can affect formulation performance and aid the formulation chemist in selecting the optimum performing surfactant system.
