Physical and material properties of an emulsion‐based lipstick produced via a continuous process
Water‐in‐oil emulsions in lipsticks could have the potential to improve moisturizing properties and deliver hydrophilic molecules to the lips. The aim of this work was to investigate the effect of a continuous process (scraped surface heat exchanger (SSHE) and pin stirrer (PS)) on the physical and material properties of an emulsion‐based lipstick by altering the processing conditions of both the SSHE and PS.
