“…Initially, the zeta potential measurement of the inorganic UV filters added to the formulations was accomplished. Since these inorganic materials are known to be insoluble in the formulation environment, they were suspended in the medium; this situation is related to the emulsion stability and may lead to phase separation, flocculation or coalescence [18,19,20]. High zeta potential values (in modulus) indicate greater electrostatic repulsion for the particles suggesting greater stability for the studied formulations [18,19,20].…”

High zeta potential values (in modulus) indicate greater electrostatic repulsion for the particles suggesting greater stability for the studied formulations [18,19,20]. The results demonstrate that ZnO, TiO 2 and CePO 4 possess sufficient charge for an adequate electrostatic repulsion, which should maintain the emulsion stability (Figure 1) [18,19,20].…”

“…Another important factor to take into account in the development of cosmetic formulations containing inorganic UV filters is the zeta potential values; it allows evaluating the behavior of the inorganic UV filters, since its intrinsic characteristics play an important role in the formulation stability. The zeta potential is a parameter that indicates the properties of the interface and of the solid solution near the interface [18,19]. The electrophoretic mobility of the dispersed particles in charged electric fields is usually used for zeta potential measurements.…”

Inorganic UV filters have become attractive because of their role in protecting the skin from the damage caused by continuous exposure to the sun. However, their large refractive index and high photocatalytic activity have led to the development of alternative inorganic materials such as CePO 4 for application as UV filters. This compound leaves a low amount of white residue on the skin and is highly stable. The aim of this study was to evaluate the physical and chemical stability of a cosmetic formulation containing ordinary organic UV filters combined with 5% CePO 4 , and, to compare it with other formulations containing the same vehicle with 5% TiO 2 or ZnO as inorganic materials. The rheological behavior and chemical stability of the formulations containing these different UV filters were investigated. Results showed that the formulation containing CePO 4 is a promising innovative UV filter due to its low interaction with organic filters, which culminates in longer shelf life when compared with traditional formulations containing ZnO or TiO 2 filters. Moreover, the recognized ability of CePO 4 to leave a low amount of white residue on the skin combined with great stability, suggests that CePO 4 can be used as inorganic filter in high concentrations, affording formulations with high SPF values.

“…In plastic packaging, similar to packaging used for cosmetic products, about 20 g of the sample was exposed to at least five cycles of alternate temperature, i.e., 24 h at high temperatures (40 • C) and 24 h at low temperatures (4 • C). Analytical centrifugation was carried out (3000 rpm) for 60 min at room temperature (20 • C) [34,35]. The determination of pH was conducted in an aqueous dispersion of 10% (w/v), as obtained by the dispersion of 1 g of sample in freshly distilled water (9 mL), homogenized with a magnetic stirrer, and measured by a pH meter, in triplicate.…”

Plant selection, input, and field management are proven strategies that produce high yields of crops bearing selected desirable characteristics for the nutraceutical and cosmeceutical industry. This study reports on the effect of substrate and light on selected quantitative and qualitative bioactive properties of two cultivars of Rubus idaeus L. ('Ruvi' and 'Cayuga'). Our results demonstrated that the quantitative and qualitative fruit characteristics (yield, fruit dimensions, titratable acidity, and total soluble solids contents), plant growth, biosynthesis of secondary metabolites, and total antioxidant capacity, are significantly affected by genotype, light intensity, and substrate type. Fruits from 'Ruvi' plants cultivated under low light conditions, on soil/peat substrate exhibited high levels of antioxidant capacity, phenolics, flavonoids, anthocyanins, and high inhibitory potency towards the skin-regulating enzymes tyrosinase and elastase. Extract derived from these fruits was formulated into a topical skin care cream. This cream exhibited excellent compatibility and stability characteristics. Our research concluded that quantity and quality of Rubus idaeus L. fruits could be efficiently managed through conventional agronomic practices. Our project determined the optimal agronomic management practices to produce desirable characteristics and maximize bioactive content that determine the nutraceutical and cosmeceutical quality of the red raspberry.

Many advanced methods are developed for the synthesis of emulsions in the literature, but the effect of imperative parameters of emulsion like oil concentration, pH, temperature, and time on the emulsion stability index (ESI) by design of experiments have not been studied previously. The ESI is an important parameter of emulsion to run the industrial process extensively and reflects the emulsion efficiency to sustain against instability like creaming, coalescence, and flocculation. In the present study, the research plan consists of three phases. In the first phase, the synthesis of an eco-friendly and cost-effective mustard oil-based nanoemulsion with a suitable selection of the surfactant on the bases of the polydispersity index (PDI) is developed. In the next phase emulsions, characteristic properties are scanned by employing various techniques and antirust property compared with reference emulsion. Finally, the impact of emulsion's parameters on ESI is studied by factorial design. The findings that depict the impact of parameters of oil concentration and time on ESI are found influential, whereas the effect of pH and temperature is insignificant. Therefore, good characteristic results, stability, and the inhibition against rust of newly developed emulsion can be adapted to run the cold rolling process smoothly. Practical Application: In the present era, metal processing industries are forced to explore the environmentally friendly oil-in-water emulsions (that used as an interface, lubricant, cooling, and antifrictional agents in cold rolling industries) to overcome increasing environmental pollution. Mustard oil-based emulsion modified by nanoparticles (Nps) offers a good source of eco-friendly, cost-effective, and economic booster for metal processing industries. The antimicrobial properties of mustard oil are well defined in previous research articles. Such oil is a magnificent source for the synthesis of the emulsion and modification of mustard oil-based emulsion with titanium dioxide. Nps provide significant protection against rust. Such applications can encourage the use of mustard oil-based nanoemulsion for metal processing industries.
