Shaving cream-based foams composed of stearic acid (SA), triethanolamine (TEOA), and water are stable at long times. Further, these foam solutions have low surface tension and high bulk viscosity, key properties that lead to stable foam formation. Despite the ubiquity of shaving cream, we do not yet understand why aqueous SA+TEOA systems foam so well, nor what chemistry underlies the physicochemical properties that allow such stable foams to form. This project aims to determine the correlations between SA+TEOA aqueous foam chemistry, rheology, and foam performance.
