Micelles: structure, function and formation - science - 2024

When surfactants are present above the critical micelle concentration (CMC), they can act as emulsifiers that will allow a compound that is normally insoluble (in the solvent being used) to dissolve. This occurs because the insoluble species can be incorporated into the micelle core, which is itself solubilized in the bulk solvent by virtue of the head groups' favorable interactions with solvent species. The most common example of this phenomenon is detergents, which clea… WebMicelles can act as emulsifiers. That means it allows a molecule which is insoluble in water to be solubilized. A soap basically inserts its tail into the insoluble dirt, while it inserts its head towards the dirt that is nonpolar. Thus, soaps can help in cleaning oily substances in which water is unable to clean alone. trust and estate lawyer salary
