Improving Foam Stability of Ethanol/Water Mixture with Anionic Surfactant and Long-chain Alcohol
We assessed foam stability in ethanol/water mixtures in the presence of an anionic surfactant, sodium dodecyl sulfate, with long-chain alcohols. The foam stability was significantly improved by the coaddition of the long-chain alcohols. We found that adding the long-chain alcohols increased the surface viscosity, by forming a mixed adsorption film at the air/solution interface.
