Nanoemulsion: Application in body-care products

Nanoemulsion (NE), which is an attractive emulsion, has been widely used in a range of applications such as cosmetics, pharmaceuticals, medicine, and food and beverages. In cosmetics, it has been indicated that there is a close relationship between body-care products and NEs; and NEs play a vital role in the development of advanced cosmetic formulations. In body-care cosmetic formulations, NEs are commonly applied as medium for protection and controlled delivery of active agents in a diversity of formulations including shampoos, sunscreens, lotions, conditioners, deodorants, and hair serums. In this chapter, we provide a general description and definition of structural components, common preparation techniques, and outstanding characteristics of NEs in the cosmetics field. Furthermore, some detailed body-care products designed and developed based on NEs are also discussed and depicted in depth.
