Synthesis and properties of multilayered films foams

• This innocuous system combines a good foamability and remarkable foam stability.
• The generated foams are multilayered liquid films.
• The stabilization mechanism relies on solubilization of TDA and hydrophobicity, hydrophobicity of GAC.

The unstable nature of liquid foams is hampering their use in all the applications. This work presents a simple and versatile approach to prepare an innocuous system that combines a good foamability and remarkable foam stability. Anionic surfactant sodium dodecyl sulfate (SDS), gum acacia (GAC) and 1-Tetradecanol (TDA) were selected as main foaming agent, foam stabilizer and accessory ingredient respectively, which allowed the foams to present the performance of remarkable stabilization and multilayered liquid films. Besides, the differences of foam sizes have been obviously reduced, and bubble sizes are small and in range of 20–60 μm.
