Impact of nonionic surfactants on the water activity of binary and ternary aqueous solutions

Key Points

• The study aims to examine how nonionic surfactants influence the water activity of binary and ternary aqueous solutions.
• Conducted experiments on binary and ternary aqueous solutions with varying surfactant concentrations.
• Measured surface tension and water activity in the presence of surfactants.
• Analyzed the partitioning effects in aerosol droplets.
• Nonionic surfactants significantly reduced water activity in both binary and ternary solutions.
• The presence of surfactants led to observable changes in surface tension, indicating altered droplet behavior.
• Water activity changes suggest implications for aerosol dynamics in the atmosphere.
