“…Quercetin, which was used as a positive control because of its high antioxidant activity, showed >50 % inhibition. Although its antioxidant activity was lower than that of quercetin, this product may potentially exert anti‐aging properties, as reported elsewhere for formulas containing plant‐derived antioxidant compounds [28–30] …”

Pink pepper (Schinus terebinthifolius Raddi) has high potential for commercial use because of its biological activities (anti-inflammatory, antitumor, and antioxidant activities, among others). Herein, the antioxidant activity of a topical formulation containing pink pepper extract obtained by supercritical carbon dioxide extraction is reported. The effects of extraction pressure (100-300 bar) and temperature (40 -60 °C) on its antioxidant activity were investigated. The extracts obtained at 50-60 °C showed a higher inhibition percentage in the α,α-diphenylβ-picrylhydrazyl (DPPH) assay (80.16 -91.27 %), regardless of pressure. The extract obtained under optimized conditions (200 bar and 50 °C) was incorporated into an oil-in-water emulsion containing 2 % (m/m) pink pepper extract. The product presented a creamy texture, light rose color, mild spicy odor, and desirable pH for a topical formulation. Furthermore, the product was stable and remained effective when stored and protected from heat and light, showing 35.38 % inhibition of DPPH.

“…Similarly to the viscosity data, the increase in hyaluronic acid concentration and lecithin's presence in ethosomes increase the adhesiveness. In contrast, the presence of the extract decreases the adhesiveness when it is non-encapsulated [47].…”

Rising environmental awareness drives green consumers to purchase sustainable cosmetics based on natural bioactive compounds. The aim of this study was to deliver Rosa canina L. extract as a botanical ingredient in an anti-aging gel using an eco-friendly approach. Rosehip extract was first characterized in terms of its antioxidant activity through a DPPH assay and ROS reduction test and then encapsulated in ethosomal vesicles with different percentages of ethanol. All formulations were characterized in terms of size, polydispersity, zeta potential, and entrapment efficiency. Release and skin penetration/permeation data were obtained through in vitro studies, and cell viability was assessed using an MTT assay on WS1 fibroblasts. Finally, ethosomes were incorporated in hyaluronic gels (1% or 2% w/v) to facilitate skin application, and rheological properties were studied. Rosehip extract (1 mg/mL) revealed a high antioxidant activity and was successfully encapsulated in ethosomes containing 30% ethanol, having small sizes (225.4 ± 7.0 nm), low polydispersity (0.26 ± 0.02), and good entrapment efficiency (93.41 ± 5.30%). This formulation incorporated in a hyaluronic gel 1% w/v showed an optimal pH for skin application (5.6 ± 0.2), good spreadability, and stability over 60 days at 4 °C. Considering sustainable ingredients and eco-friendly manufacturing technology, the ethosomal gel of rosehip extract could be an innovative and green anti-aging skincare product.

New antioxidant lauryl-free herbal shampoo formulation with a Brazilian plant extract

Sodium lauryl sulfate is the main cleaning ingredient in shampoos, even though it may be potentially damaging to hair. The demand for antioxidant-rich cosmetics, on the other hand, has encouraged green cosmetics research. Brazil has vast biodiversity that can be exploited for the production of these cosmetics. This work aimed to develop a minimalist antioxidant lauryl-free shampoo formulation with leaf extracts from the Brazilian plant Hancornia speciosa Gomes. Two hydroethanolic extracts were prepared using different extraction methods, Soxhlet, and ultrasound. The extracts were characterized by the presence of saponins, polyphenol quantification, and HLPC chemical identification of the compounds. Antioxidant activity was determined using the DPPH method. The antioxidant lauryl-free shampoo was developed using hydroxyethyl cellulose with two concentrations of leaf extract obtained by Soxhlet, 0.125 mg/g (XP1) and 0.250 mg/g (XP2). Along with the antioxidant activity, the physical and chemical properties, cleaning potential, and foam quality were evaluated. The Soxhlet leaf extract revealed a more favorable chemical profile, including a positive result for saponins, as well as a larger quantity of polyphenols and increased antioxidant activity. The XP2 formulation showed better foam height, dirt dispersion, and antioxidant activity. Thus, the use of mangabeira leaf extract appears to be promising for the development of shampoos with antioxidant activity.
