“…Little attention is given to silica-filled NR compound, despite the great difference in surface activity of these fillers. Recently, it has been reported that Moringa oil (MO) and Niger oil (NO) contain relatively high oleic acid content (>70%) and linoleic acid content (>70%), respectively, which is interesting for many applications such as cosmetic, food, medicine, biopesticide and biodiesel [16][17][18]. However, there are no previous works reporting the effect of MO and NO on physical and dynamic properties of NRC.…”

Owing to the toxicity of polycyclic aromatic (PCA) oils, much attention has been paid to the replacement of PCA oils by other nontoxic oils. This paper reports comparative study of the effects of new vegetable oils, i.e., Moringa oil (MO) and Niger oil (NO), on rheological, physical and dynamic properties of silica–filled natural rubber composite (NRC), in comparison with petroleum–based naphthenic oil (NTO). The results reveal that MO and NO exhibit higher thermal stability and better processability than NTO. Cure characteristics of the rubber compounds are not significantly affected by the oil type. It is also found that the NRCs containing MO or NO have better tensile strength and lower dynamic energy loss than the NRCs containing NTO. This may be because both MO and NO improve filler dispersion to a greater extent than NTO as supported by storage modulus and scanning electron microscopy results. Consequently, the present study suggests that MO and NO could be used as the alternative non–toxic oils for NRC without any loss of the properties evaluated.

“…Previous studies described a similar rheological profile for hydrogels containing C. sativa leaf and bur extracts [19,28]. Likewise, Athikomkulchai et al related a pseudoplastic character for a cream incorporating moringa seed oil [30]. In addition, no significant changes (p > 0.05) were detected in the viscosity of creams containing açai extract [29].…”

“…In addition, a slightly lower pH (5.02-5.05) was obtained for emulsions with açai extract (0.5-2%) [29]. Athikomkulchai et al formulated a cream containing Moringa oleifera seed oil as an active agent, describing a pH of 5.43 in comparison with the base cream (5.07) [30].…”

“…For instance, Censi et al also described a thixotropic profile for O/W emulsions incorporating açai extract, emphasizing the marked viscosity at higher shear rates and no total recovery of the initial viscosity after ceasing the shear rate [29]. Athikomkulchai et al underlined the shear-thinning behavior of M. oleifera seed oil cream without a yield stress, suggesting that the increase of shear rate when the formulation is applied may lead to a low resistance to flow and the release of moringa seed oil to the skin [30]. In contrast, Almeida et al reported that the hydrogel containing chestnut leaf extract did not exhibit pronounced thixotropy [19].…”

Characterization and Stability of a Formulation Containing Antioxidants-Enriched Castanea sativa Shells Extract

et al. 2021

The cosmetic industry is a field on rise where the search for novel antioxidant ingredients, preferably from natural matrixes, became a new challenge. The reuse of Castanea sativa shells as a source of phytochemicals with pro-healthy effects in skin care products may be a valuable alternative to valorize this underexploited agro-industrial by-product. A previous study of our research group demonstrated the antioxidant properties of chestnut shells extract obtained by ultrasound-assisted extraction (UAE), as well as its safeness on skin cell lines, namely keratinocytes and fibroblasts. Based on the extract richness in antioxidants, a formulation containing C. sativa shells extract obtained by this environmentally friendly technology was successfully developed in the present study. The oil-in-water (O/W) cream incorporating the chestnut shells extract was further characterized regarding organoleptic and technological properties, namely color, pH, droplets size, and viscosity. A stability study over time was also accomplished. The results demonstrate that the formulation not only displayed pleasant organoleptic characteristics attractive to consumers but also a pH compatible with skin and a suitable viscosity for topical application. The stability study revealed minor changes to droplet size and color, without affecting the general stability of the formulation. In conclusion, this study emphasized the prominent benefits of chestnut shells extract as a novel ingredient for skin care formulations.

“…The DPPH free radical scavenging capacity of the B. flabellifer male flower extract was determined and compared with gallic acid, quercetin, EGCG, and ascorbyl glucoside [ 44 , 45 ]. Gallic acid, EGCG, ascorbyl glucoside, and B. flabellifer male flower extract were diluted in deionized water, and quercetin was diluted in 95% ethanol at concentrations of 3.9–2000 µg/mL.…”

Borassus flabellifer L. is a plant in Arecaceae family, widely distributed and cultivated in tropical Asian countries. The purpose of this study was to identify the bioactive compounds of B.flabellifer L. male flower ethanolic extract and investigate the antioxidant, anti-inflammatory, and antibacterial activities against Cutibacterium acnes. Total phenolic compounds and total flavonoids in B.flabellifer L. male flower ethanolic extract were determined by the Folin–Ciocalteu method and aluminum chloride colorimetric assay, respectively. Active substances in the extract and their quantities were analyzed by liquid chromatography and mass spectrometry (LC–MS/MS). The antioxidant evaluation was carried out using DPPH, ABTS free radical scavenging assays, and FRAP assay. C. acnes inhibitory activity was performed by the broth microdilution method. Anti-inflammatory activity was determined by the protein denaturation assay. In addition, gel containing different amounts of B.flabellifer L. male flower extract was formulated. The physical stability of the gel was observed by measuring viscosity and pH after six heating and cooling cycles, as well as 1-month storage at 4, 30, and 45 °C. The total phenolic content in the extract was 268.30 ± 12.84 mg gallic acid equivalent/g crude dry extract. The total flavonoid contents in the extract were 1886.38 ± 55.86 mg quercetin equivalent/g extract and 2884.88 ± 128.98 mg EGCG equivalent/g extract, respectively. The LC–MS/MS analysis revealed the presence of gallic acid, coumarin, and quercetin and the concentrations of quercetin, coumarin, and gallic acid in B. flabellifer male flower ethanolic extract were 0.912, 0.021, and 1.610 µg/mL, respectively. DPPH and ABTS antioxidant assays indicated that the B.flabellifer L. male flower extract had IC50 values of 31.54 ± 0.43 and 164.5 ± 14.3 µg/mL, respectively. FRAP assay revealed that the B.flabellifer male flower extract had high ferric ion reducing power. The extract was able to inhibit C.acnes bacteria with a minimum inhibitory concentration (MIC) of 250 mg/mL. At 250 and 500 µg/mL, the extract demonstrated the highest anti-inflammatory activity. The gel containing 31.25% w/w and 62.5% w/w showed good physical stability after six heating and cooling cycles, as well as 1-month storage.
