The present differential scanning calorimetry (DSC) study of eight commercial bar soap products has resulted in the assignment of DSC thermal absorptions to three key polymorphic states of soap (also known as“soap phases”): Δ, β,Ω. The DSC data have also been correlated with polymorphic states of soap identified previously by x‐ray diffraction (XRD) method. The correlations of quantitative DSC data with consumer‐perceived lathering attributes and experimentally determined solubility properties of these bars also are discussed.
