Relationship between the Texture and the Physical Properties of Coacervate in Shampoo

Abstract

Currently, shampoo products are combined anionic surfactants, amphoteric surfactants and cationic polymer in order to give a smooth texture to the hair surface. These substrates are generated by coacervation in the washing and rinsing processes. However, the relationship between the physical properties of coacervation and the tactile texture has not been uncovered. In this study, we demonstrated characteristics of coacervation and tactile texture in amino acid-type surfactant, amphoteric surfactant and cationic polymer systems. In these results, it is shown that tactile texture and physical properties depend on the variety of amphoteric surfactants. The characteristic tactile textures created by replacing amphoteric surfactants were smooth, moist, and resilient. Furthermore, it was confirmed that the physical properties were different in the coacervation obtained by various formulations. These findings suggest that the features of the generated coacervation influenced the tactile texture.
