“…These non-ionic natural surfactants are obtained by esterification of natural glycerol, as the hydrophilic part of a surfactant molecule, with fatty acids from different natural plant oils as its lipophilic domains. Depending on the number of glycerol units with different degrees of esterification and the properties of fatty acids (e.g., chain length and unsaturation), various polyglycerol esters and their mixtures can be obtained [ 18 , 19 ]. Apart from some patents with limited information [ 20 , 21 ], only a few reports are available regarding the formation of O/W nanoemulsions or microemulsions with polyglycerol esters via the low energy methods [ 22 , 23 , 24 , 25 ].…”

This study focuses on the development of biocompatible oil-in-water (O/W) nanoemulsions based on polyglycerol esters, as promising carriers for natural actives: red raspberry seed oil—RO and hydro-glycolic fruit extracts from red raspberry—RE and French oak—FE. Nanoemulsions were obtained via phase inversion composition (PIC) method at room temperature by dilution of microemulsion phase, confirmed by visual appearance, percentage of transmittance, microscopic, rheological and differential scanning calorimetry (DSC) investigations. The results have shown that the basic RO-loaded formulation could be further enriched with hydro-glycolic fruit extracts from red raspberry or French oak, while keeping a semi-transparent appearance due to the fine droplet size (Z-ave: 50 to 70 nm, PDI value ≤ 0.1). The highest antioxidant activity (~92% inhibition of the DPPH radical) was achieved in the formulation containing both lipophilic (RO) and hydrophilic antioxidants (FE), due to their synergistic effect. The nanoemulsion carrier significantly increased the selective cytotoxic effect of RO towards malignant melanoma (Fem-X) cells, compared to normal human keratinocytes (HaCaT). In vivo study on human volunteers showed satisfactory safety profiles and significant improvement in skin hydration during 2 h after application for all nanoemulsions. Therefore, polyglycerol ester-based nanoemulsions can be promoted as effective carriers for red raspberry seed oil and/or hydro-glycolic fruit extracts in topical formulations intended for skin protection and hydration.

Rice bran is a by-product of great production worldwide and its use for the synthesis of biodiesel does not affect the food chain and therefore it is an excellent alternative for the production of biofuels with low carbon footprint. In this work, the synthesis of biodiesel was carried out from the raw rice bran oil of a kernel variety called “Morelos rice.” The stability and corrosivity characteristics of biodiesel were determined. Biodiesel stability was determined both under storage conditions and under accelerated oxidation conditions, and its corrosivity was evaluated by electrochemical impedance spectroscopy at 110°C under aerated conditions. The results showed that, due to the high instability of the rice bran, its raw oil had a high content of free fatty acids. The synthesized biodiesel showed excellent stability under storage conditions of up to five months, and its oxidative stability was much higher than that established in international standards. On the other hand, biodiesel showed low corrosivity and this was only significant once oxidative degradation began.

“…Hanno et al [15] reported the use of a rice-derived natural surfactant with emulsifying properties as a green cosmetic approach. In vitro cytotoxicity test and experiments in human volunteers proved that the rice panicle extract contains high levels of phenolic compounds, which provides the nourishment and acted as a skin antiaging agent [28].…”

“…Rice bran oil (RBO) is rich in unsaturated fatty acids (oleic, linoleic, and α-linolenic acids) and saturated fatty acids (palmitic and stearic acids). RBOs are used in the cosmetic products, mainly in sunscreen, antiaging, and skin-lightening products, because of its bioactivities and moisturizing properties on the skin [11][12][13][14][15]. Thai-pigmented rice has been reported as an active ingredient in cosmetics, pharmaceuticals, and functional foods [16].…”

Objective: The rice bran (RB) phytochemicals are known for several pharmacological properties. The current study was aimed to extract the active principles from Thai purple RB, formulate the cosmetic products, and evaluate the physical property and stability of the products.Methods: Purple RB was extracted using 80% ethanol, and total phenolic and anthocyanin contents were measured using high-pressure liquid chromatography (HPLC) and spectrophotometric methods. Rice bran oil (RBO) was obtained by cold press method, and oryzanol content was determined using HPLC. The antioxidant capacity of RBO and purple rice bran extract (PRE) was assessed using spectrophotometric methods. The cosmetic products were formulated with PRE and fermented and distilled purple rice solution (FDPRS). RBO was also used as an ingredient in the formulation of solid soap. The stability of the formulations was also assessed. The heavy metal and microbial contamination were determined using atomic absorption spectrometry and plating assay, respectively. Results:The yield of PRE and RBO was 0.92 and 1.62%, respectively. The total phenolic and anthocyanin content of PRE was 305.30±6.15 mg gallic acid/g of extract and 877.33±87.73 mg cyanidin chloride/g of extract, respectively. Oryzanol content of RBO was 6.33±0.09 mg/g of RBO. RBO, PRE, and FDPRS exhibited high antioxidant capacity. The cosmetic formulations were observed to be physically stable in the heat-cool cycle, and the stability of the active compounds was not affected while stored at 30°C for 2 months. The storage temperature affected the phenolic compounds present in the cosmetic formulations, especially at 45°C. There was no significant decrease in oryzanol content of soap formulation. All the formulations were free from microbial and heavy metal contamination. Conclusion:The RB phytochemical-based cosmetic products are rich in antioxidants, stable, and free from heavy metals and microbial contamination, and further fine-tuning of the formulation may achieve the market quality.
