“…Finally, they were covered with foil paper to prevent light degradation and stored in a refrigerator until further use. The average yield obtained was 62.9 ± 0.3% (dry basis), which is in accordance with the literature values, between 21.5-71%, using maceration and ultrasound as extraction techniques [22,23].…”

The excessive use of water and plastic packaging in the cosmetic industry imposes the need to develop sustainable alternatives. Moreover, agricultural by-products are reported in the literature to be rich in bioactive properties, namely high antioxidant capacity, suggesting their potential use in cosmetic formulations as substitutes for commercial additives. The aim of this work was the development of a sustainable formulation of solid shampoo, incorporating extracts from mango peel as antioxidants. The characterization of the extracts revealed the presence of several phenolic compounds and a strong antioxidant capacity. Six formulations of solid shampoo were produced by varying the quantity of the additives: tocopherol and butylated hydroxytoluene, used as positive controls, and mango peel (MP) extract. The antioxidant capacity assays demonstrated that the MP extract increased the antioxidant activity of the shampoos, in comparison to the positive controls and the stability tests revealed that the MP extract is a stable ingredient. Hence, it was concluded that the MP extract is a strong source of antioxidants with the potential to replace commercial antioxidants in cosmetics. Thus, it was possible to develop a value-added formulation of solid shampoo, eliminating the use of water and plastic for the packaging, and reusing waste from the food sector.

“…The recovery of this antioxidant from byproducts of the food industry is a promising way of forwarding the circular economy model, which has its focus on sustainable use of resources and on the minimization of waste generation to reduce the environmental impact of the processes. − The wine industry generates a substantial amount of organic residues, such as seeds and peels, which contain high concentrations of phenolic compounds . For example, in the case of red wine, the concentration of trans-RVT generally ranges between 0.1 and 15 mg/L …”

Antioxidant-rich food supplements can effectively address widespread nutritional deficiencies in the human diet and simultaneously reduce the concentration of reactive oxygen species (ROS) due to the free radical scavenging activity of antioxidants, minimizing inflammation and oxidative stress. Resveratrol (RVT) is a very important antioxidant which can be extracted from food industry byproducts such as grape skins, contributing to a more circular economy and reducing the environmental impact of the extraction processes. In this work, RVT was successfully extracted in the aqueous two-phase systems (ATPSs) {ethyl lactate (1) + Na 3 Citrate or K 3 Citrate or Na 2 Succinate or NaKTartrate (2) + water (3)} at 298.15 K and 0.1 MPa, which provided biocompatible and sustainable extractive media. The studied ATPS yielded partition coefficients (K) above unity, indicating a preference for the top phase (rich in ethyl lactate), which hints at a successful extraction of this phenolic compound. Larger tie-lines generally resulted in larger partition coefficients (K) and larger extraction efficiencies (E), favoring solute migration to the top phase. The most promising partition coefficients (K = 40 ± 6 and 41 ± 9) and extraction efficiencies (E/% = 98 ± 1 and 95.0 ± 0.6) were obtained for the longest tie-lines (TLL = 77.66 and 70.73 m%) for {ethyl lactate (1) + K 3 Citrate (2) + water (3)} and {ethyl lactate (1) + NaKTartrate (2) + water (3)}, respectively. Additionally, the effect of pH on the UV−vis absorbance spectrum of RVT was studied to minimize errors in solute quantification, resulting in low antioxidant mass losses (<5%).
