“…5a , an essential component of the stratum corneum 42,43 , because both of the lipids consist of two fatty acids and sugar moieties, and are capable of forming various lyotropic liquid crystals, including the lamellar phase 5 . As previously reported, the moisturizing activity was evaluated using a three-dimensional cultured human skin model, TESTSKIN TM Toyobo, Japan based on the cell viability 44,45 . The sodium dodecyl sulfate SDS -damaged human skin cells were prepared, and then the effects of different lipids on viability of the SDS-damaged cells.…”

“…The reaction scheme and the structure of the polyglycerol esters are represented in Figure 1. This feature is interesting because the liquid crystal system could enhance the stability and moisturizing ability of the emulsion [35][36][37][38].…”
During recent years, microwave irradiation has been extensively used for performing green organic synthesis. The aim of this study was to synthesize, through a microwave-assisted irradiation process, a natural surfactant with O/W emulsifying properties. Our attention was focused on polyglycerol esters of fatty acids that are biocompatible and biodegradable non-ionic surfactants widely used in food and cosmetic products. The emulsifier was obtained using vegetable raw material from renewable sources: polyglycerol derived from vegetable glycerol and rice bran oil fatty acids. The natural emulsifier obtained was then characterized and evaluated for its emulsifying properties using different doses, oil phases, rheological additives, waxes, etc. The potential application in solar products, in comparison with other natural emulsifiers, was also evaluated.
“…123 Moreover, the aqueous solution of mannosylerythritol lipids (5 wt%) was estimated to considerably increase the stratum corneum water content in the skin and perspiration on the skin surface was clearly suppressed by treatment with the mannosylerythritol lipids solution. 148 Also, Morita et al 149 proved the usefulness of yeast derived mannosylerythriol lipids for not only the recovery of damaged hair but also for providing it a smooth and flexible appearance. As suggested by Morita et al 77 , a mannosylerythritol lipids derived from Ustilago scitaminea, showed a ceramide-like skin-care property in a three-dimensional cultured human skin model.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
