Overview

Investigates foam performance in a composite of saponin and bio-based surfactants, suggesting improved sustainability.

Key Points

  • This research aims to enhance the foam performance of a composite system using Sapindus saponin and a bio-based surfactant.
  • Evaluated foamability and stability through surface tension measurements and microscopic tracking.
  • Constructed a multidimensional foam performance index integrating key metrics of interfacial, generation, and stability indices.
  • Analyzed different mass ratios of Sapindus saponin and bio-based surfactant to determine optimal formulation.
  • Achieved a significant reduction in equilibrium surface tension to 22.8 mN/m at a 9:1 SS:JFC-U mass ratio.
  • Determined an optimal structural half-life of 240 minutes for foam stability.
  • Identified a 5:5 mass ratio leading to antagonistic effects due to steric hindrance.
