  • Non-molten-mix process for making bar comprising acyl isethionate based solids, soap and optional filler
    Patent number: 5981451
    Abstract: Novel compositions are prepared in a non-molten process. In particular, compositions comprise optional fillers with both soap and high levels of synthetic surfactants. When high levels of soap and surfactant are normally used in such process, there is a significant "grittiness" problem. Pre-processing the surfactant containing chip (e.g., "DEFI" chip) has been unexpectedly found to remedy this problem.
