Stability and Cleansing Function Enhancement of Organic Shampoo by a Vortex Fluidic Device

Research output: Contribution to journalArticlepeer-review


Natural cosmetic products have attracted significant attention due to their eco-friendliness compared to synthetic products. The development of more benign production methods for these products not only increases the functionality and stability but also aligns them with the principles of green chemistry and organic standards. One such method uses the vortex fluidic device (VFD), which is an efficient thin-film device that utilizes a rapidly rotating tube to implement high shear forces, overcoming the mixing and heat transfer limitations of traditional batch processing. Herein, the stability and cleansing functions of a predeveloped organic shampoo are improved by incorporating the VFD processing without clogging problems. Shampoo processed by VFD in a standard 20 mm diameter tube inclined at 45° and rotating at 4500 rpm showed the most decrease in particle size and an improvement in both viscosity and storage time. The processed shampoo remained unseparated even after 30 days under 50 °C heating. In addition, the foaming and cleansing function of the processed shampoo increased, making it easier to remove dirt from hair compared to the nonprocessed product. Overall, the VFD processing technology demonstrates a green, one-step technique for value-added natural cosmetic products such as organic shampoo.
