Overview

Observational analysis reveals that additives modify rheology and phase behavior in surfactant solutions, suggesting new design strategies.

Key Points

  • Additives significantly influence the rheology and phase behavior of surfactant systems, particularly at varying degrees of ethoxylation.
  • Using linear-chain alcohols can induce transitions from lamellar to micellar structures, affecting the overall viscosity.
  • Common salt enhances shear-induced crystallization within the lamellar phase, impacting the microstructure of surfactant solutions.
  • Propylene glycol alters rheological properties by forming lubrication layers and reducing crystallization, indicating potential processing benefits.
