| Abstract: | The facial cleansing products segment has grown over the years and most surfactant-based systems do not retain many of the active ingredients on the skin. Development of a positively charged vesicle as the delivery vehicle for personal cleansing products is based on the negatively charged nature of the skin surface. Chitosan has the potential to be used as a vesicle to encapsulate active ingredients and can be used in facial formulations that are based on amphoteric surfactant with or without the addition of nonionic surfactant. This review briefly summarizes the potential of chitosan nanoparticles as the delivery system in facial cleansing formulations. |
