The Synergistic Behavior of Antioxidant Phenolic Compounds Obtained from Winemaking Waste’s Valorization, Increased the Efficacy of a Sunscreen System

Grape pomace retains polyphenols in the peels and in the seeds after winemaking, which is indicative of the high valorization potential of this industrial waste. There is strong evidence that phenolics are robust antioxidants and confer photoprotection; thus, it is rational to apply these active compounds from winemaking waste to sunscreens, in order to increase UV protection. Despite the importance of this class of cosmetics to public health, more efficacious strategies are still needed to overcome the problems caused by the photoinstability of some UV filters. The hydroethanolic extract of Vitis vinifera L. grapes was obtained by percolation and then lyophilized. Six formulations were developed: Type I—cosmetic base and UV filters; Type II—cosmetic base and extract; and Type III—cosmetic base, extract and UV filters. Each formulation was prepared in the pHs 5 and 7. The antioxidant activities of the samples were measured by DPPH• and expressed in Trolox® equivalents (TE), and their photostability and in vitro sun protection factor (SPF) were analyzed by diffuse reflectance spectrophotometry. The anti-radical efficiencies observed in the formulations with grape extract were: (II) 590.12 ± 0.01 μmol TE g−1 at pH 5 and 424.51 ± 0.32 μmol TE g−1 at pH 7; (III) 550.88 ± 0.00 μmol TE g−1 at pH 5 and 429.66 ± 0.10 μmol TE g−1, at pH 7, demonstrating that the UV filters, butylmethoxydibenzoyl methane, ethylhexyl methoxycinnamate and ethylhexyl dimethyl 4-aminobenzoic acid had no influence on this effect. The photoprotective efficacy and the photostability of formulation III containing the extract and UV filters at pH 5 suggested that a synergism between the active molecules provided an 81% increase in SPF. Additionally, this was the only sample that maintained a broad spectrum of protection after irradiation. These results confirmed that the grape pomace extract has multifunctional potential for cosmetic use, mainly in sunscreens, granting them superior performance.

“…Soto et al [91] evaluated the potential of the use of some vegetal raw materials, including A. dealbata flowers, in personal-care products (hand cream, body oil, shampoo, clay mask, body exfoliating cream and skin cleanser), with the evaluation being made by participants attributing a classification for some sensory attributes and overall acceptance. Between the four assayed vegetal extracts (grape pomace, Pinus pinaster wood chips, A. dealbata flowers and Lentinus edodes), the floral aroma and the yellow color provided by the A. dealbata flower extract to all produced cosmetic products, make the acacia-based products preferred by all consumers, independent of gender or age [91]. Besides, the A. dealbata extract was the one with the highest antioxidant activity, given by the ferric-reducing antioxidant power assay (170 mg ascorbic acid equivalents per gram of extract) and the ABTS free radical scavenging assay (700 mg of trolox equivalents per gram of extract) [91].…”

Acacia spp. are widespread all over the Portuguese territory, representing a threat to local biodiversity and to the productivity of the forest sector. The measures adopted in some countries for their eradication or to control their propagation are expensive, have been considered unfeasible from practical and economical perspectives, and have generated large amounts of residue that must be valorized in a sustainable way. This review brings together information on the valorization of bark, wood, leaves, flowers, pods, seeds, roots, and exudates from Acacia spp., through the production of high-value bioactive extracts (e.g., antioxidant, antimicrobial, anti-inflammatory, antidiabetic, antiviral, anthelmintic, or pesticidal agents, suitable to be explored by pharmaceutical, nutraceutical, cosmetics, and food and feed industries), its incorporation in innovative materials (e.g., polymers and composites, nanomaterials, low-cost adsorbents), as well as through the application of advanced thermochemical processes (e.g., flash pyrolysis) and pre-treatments to decompose biomass in its structural components, regarding the production of biofuels along with valuable chemicals derived from cellulose, hemicellulose, and lignin. The knowledge of this research is important to encourage an efficient and sustainable valorization of Acacia spp. within a biorefinery concept, which can bring a significant economic return from the valorization of these residues, simultaneously contributing to forest cleaning and management, to reduce the risk of fires, and to improve the social-economic development of rural areas.

“…They could be employed to obtain natural extracts with added value. In fact, the potential of natural extracts obtained from the residues of the wood industry, such as chips or leaves, in the cosmetic industry for the formulation of cosmetics 4–6 or as food additives, 7 has been demonstrated. For this reason, it is important the characterization of their main chemical constituents and, in this way, several studies have been reported.…”

The chemical composition of several by-products, chips, screw waters, and concentrates from a fiberboards manufacture green industrial process, which only employs wood and water, was deeply evaluated. The three by-products analyzed represent different steps of the industrial process. In addition, different types of wood: pine, walnut, chestnut, oak and cherry tree, were evaluated. For all of them, total polyphenols content, and antioxidant activity have been assessed, showing significant differences. To characterize the volatile compounds, an environmentally friendly technique, solid-phase microextraction has been employed. Besides, aqueous and generally recognized as safe organic extracts obtained from the by-products have been prepared, and their chromatographic fingerprint was obtained by gas chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry to identify extractable organic wood components. Significant differences were observed between the studied by-products and wood types. More than 30 different compounds were successfully identified in the screw waters, and concentrates, including terpenes, sesquiterpenes, or polyphenols. Regarding the obtained extracts, up to 30 compounds were identified in the chips, screw waters, and concentrate extracts, highlighting the presence of 13 polyphenols in the cherry tree chips and more than 20 compounds with interesting properties in the concentrate extracts. This work contributes to improve the knowledge about the chemical composition of several wood industry by-products, which could be exploited to obtain natural extracts with added value for their reuse in the food, cosmetic, or pharmaceutical industry, reducing also the environmental impact of the industrial activity.
