“…This may be connected with the poor aqueous solubility of PR driving the apportioning of PR into oil centre of PR‐NEs. Similar high entrapment efficiencies (>98%) have been detected in a number of other nanoemulsion systems .…”

“…Entrapment efficiencies of PR‐NE (PR 3 mg mL −1 ), PR‐NE (PR 6 mg mL −1 ) and PR‐NE (PR 9 mg mL −1 ) were determined with ultrafiltration–centrifugation method. Hardly any PR could be detected in the aqueous phase, indicating that the entrapment efficiencies were nearly 100% . This may be connected with the poor aqueous solubility of PR driving the apportioning of PR into oil centre of PR‐NEs.…”

A great attention has been received in the last few years for nanotechnology applications in food as well as pharmaceutical industries. People are looking for healthy and safe food worldwide. Therefore, researchers have been currently focusing on nanoemulsion technology that is particularly suited for the production of functional food. This chapter includes an overview about nanoemulsion terminology and formulation, various approaches for production of nanoemulsions which include high energy approaches such as high-pressure valve homogenization, microfluidizers and ultrasonic homogenization, and low energy methods such as spontaneous emulsification, phase inversion composition, phase inversion temperature and emulsion inversion point. In addition, the applications of nanoemulsions in food industry are discussed in detail.

“…Their bioactive role enhances cosmeceutical value with lower toxicity. [161][162][163][164] Recently, quercetin-rich nanoemulsions, in the size range of 200-300 nm, were prepared from the ethanolic extract of Achyrocline satureioides and showed increased skin retention of bioactive compounds with enhanced antioxidant activities in porcine skin studies. 164 In another study, genistein, a soy bioactive compound, coloaded with tocomin, acts as multiple nanoemulsions with the particle size of 173-208 nm and showed enhanced skin protection from UV damage.…”

Phytocompounds have been used in cosmeceuticals for decades and have shown potential for beauty applications, including sunscreen, moisturizing and antiaging, and skin-based therapy. The major concerns in the usage of phyto-based cosmeceuticals are lower penetration and high compound instability of various cosmetic products for sustained and enhanced compound delivery to the beauty-based skin therapy. To overcome these disadvantages, nanosized delivery technologies are currently in use for sustained and enhanced delivery of phyto-derived bioactive compounds in cosmeceutical sectors and products. Nanosizing of phytocompounds enhances the aseptic feel in various cosmeceutical products with sustained delivery and enhanced skin protecting activities. Solid lipid nanoparticles, transfersomes, ethosomes, nanostructured lipid carriers, fullerenes, and carbon nanotubes are some of the emerging nanotechnologies currently in use for their enhanced delivery of phytocompounds in skin care. Aloe vera , curcumin, resveratrol, quercetin, vitamins C and E, genistein, and green tea catechins were successfully nanosized using various delivery technologies and incorporated in various gels, lotions, and creams for skin, lip, and hair care for their sustained effects. However, certain delivery agents such as carbon nanotubes need to be studied for their roles in toxicity. This review broadly focuses on the usage of phytocompounds in various cosmeceutical products, nanodelivery technologies used in the delivery of phytocompounds to various cosmeceuticals, and various nanosized phytocompounds used in the development of novel nanocosmeceuticals to enhance skin-based therapy.
