“…Concentrated Nanostructured Dispersions with a Controllable Droplet Size . In a recent report (Salentinig et al, 2008 ), concentrated ISAsomes with various internal structures were also prepared with a laboratory -built shear device. This is achieved within a very short time interval (a few seconds) by using a similar approach to that proposed by Bibette ' s method Bibette, 1996, 1997 ), which is well -known for the preparation of monodispersed emulsions.…”

“…The type of self-assembly can be bicontinuous cubic Pn3m or Im3m, micellar cubic Fd3m, hexagonal (H 2 ) or inverse micelles (L 2 ) ( Figure 5). W/O emulsions are usually very concentrated and their stability is governed by the concentration of the components [94,95]. For instance, the emulsion can be stabilized by an optimum concentration of emulsion stabilizer or by obtaining a very high concentration of an internal phase or both of the above.…”

“…For instance, the internal self-assembly of nanostructured emulsions can be altered from cubic Pn3m to cubic Im3m by adding diglycerol monooleate or pluronic F127 to a DU lipid system [111,112]. The size of lipid nanoparticles can be modulated by changing the concentration of the dispersed phase and/or the shear rate of the shearing device [94]. Nanoscale parameters can be moderated further by using a different emulsifying lipid; for instance, GMO and PT can be used for many applications where the DU is demonstrably used [60,73,113].…”

“…The dispersed system of nanostructured lipid particles (O/W emulsions) exhibits rather low viscosity (milk-like consistency) (Figure 6), which is actually one of the main motivations behind their preparation. Nonetheless, these O/W emulsions can be made viscous, if required, by various means, for instance, by increasing the concentration of the dispersed phase (usually a lipid phase) [94] or by preparing a hydrogel in the continuous phase of these emulsions [125,126] ( Figure 6). The latter can be employed to partially arrest the dynamics of the nanostructured lipid particles [125].…”

A majority of cosmetic products that we encounter on daily basis contain lipid constituents in solubilized or insolubilized forms. Due to their amphiphilic nature, the lipid molecules spontaneously self-assemble into a remarkable range of nanostructures when mixed with water. This review illustrates the formation and finely tunable properties of self-assembled lipid nanostructures and their hierarchically organized derivatives, as well as their relevance to the development of cosmetic formulations. These lipid systems can be modulated into various physical forms suitable for topical administration including fluids, gels, creams, pastes and dehydrated films. Moreover, they are capable of encapsulating hydrophilic, hydrophobic as well as amphiphilic active ingredients owing to their special morphological characters. Nano-hybrid materials with more elegant properties can be designed by combining nanostructured lipid systems with other nanomaterials including a hydrogelator, silica nanoparticles, clays and carbon nanomaterials. The smart materials reviewed here may well be the future of innovative cosmetic applications.

“…However, the high freezing point of saturated sugar esters restricts their utilization in the foods, cosmetic, and pharmaceutical fields. In recent years, unsaturated sugar esters have attracted considerable attention due to their special characteristics, such as healthy functionality, strong surface properties, and low freezing point [2][3][4][5][6].…”

The surface properties of monoacyl trehaloses with different acyl chains were investigated at 30°C, 40°C, 50°C, and 60°C. Monoacyl trehaloses were enzymatically synthesized and purified with silica gel column chromatography and semi-preparative high-performance liquid chromatography (HPLC), and the purity of products was identified by mass spectrometry (MS) and nuclear magnetic resonance (NMR). The surface tension of monoacyl trehalose in pure water was measured using Doüy ring method at different temperatures. The critical micelle concentrations (CMC), surface tension at the CMC, γ CMC , and residual area per molecule, a, were estimated from the curves. The CMC value of unsaturated monoacyl trehalose was affected by both the degree of unsaturation and the acyl chain length, and the effect of chain length on the CMC value was much stronger than that of the unsaturation degree. However, there was no significant dependency of the γ CMC value and a values on the chain length or the unsaturated degree.
