Résumé :

Abstract This paper refers to the quality analysis of three dermo-cosmetic products: two face creams and a biphasic solution used for skin cleaning: a treatment cream for acne complexion, an anti-irritating soothing cream and a matifying purifying lotion. The following characteristics have been investigated: aspect, smell, colour, solubility, type of emulsion, stability test at certain temperatures (4°C and 40°C), pH, melting point, water, volatile substances and total fats contents, acidity, ester index, saponification index, iodine index, peroxide index, microbic carriage, metal traces (determined by ICP-MS method). All analysed dermo-cosmetic products have appropriate physico-chemical characteristics. The analyses made for determining the microbial charge have proven that the three dermo-cosmetic products do not contain any aerobic pathogen germens or micromicetes, Staphylococcus aureus and Escherichia Coli. The ICP-MS analysis has proven that the dermocosmetic products do not contain traces of Hg and Pb.

Résumé :

The search for new synthetic melanin-related pigments that maintain the antioxidant and photoprotective properties of naturally occurring dark eumelanins, while overcoming their unfavorable solubility, and molecular heterogeneity is presently a very active issue for dermo-cosmetic purposes. In this work, we explored the potential of a melanin obtained from the carboxybutanamide of a major eumelanin biosynthetic precursor, 5,6-dihydroxyindole-2-carboxylic acid (DHICA), by aerobic oxidation under slightly alkaline conditions. Analysis of the pigment by EPR, ATR-FTIR and MALDI MS indicated a substantial structural similarity to DHICA melanin, while investigation of the early intermediates confirmed unchanged regiochemistry of the oxidative coupling. The pigment exhibited a UVA–visible absorption even more intense than that of DHICA melanin, and a noticeable solubility in polar solvents of dermo-cosmetic relevance. The hydrogen- and/or electron-donor ability, and the iron (III) reducing power as determined by conventional assays provided evidence for marked antioxidant properties not merely ascribable to the more favorable solubility profile, while the inhibitory action of the radical- or photosensitized solar light-induced lipid peroxidation was more marked compared to that of DHICA melanin. Overall, these results hint at this melanin, which remarkable properties are, in part, due to the electronic effects of the carboxyamide functionality as a promising functional ingredient for dermo-cosmetic formulations.

Résumé :

Marine macroalgae have an interesting profile of bioactive compounds and have gained tremendous attention in cosmeceuticals with negligible toxicity effects (cytotoxicity, reproductive toxicity, genotoxicity, mutagenicity, carcinogenicity, etc.) on humans and exhibit strong benefits for the skin. Among the diversified compounds, phenolic compounds are the group of phytochemicals found in high amounts with great structural diversity. Phlorotannin is the most studied polyphenol compound in brown algae, but besides there are some other phenolic compounds observed and studied in macroalgae such as terpenoids, bromophenols, mycosporine amino acids (MAAs), and flavonoids. These compounds are already characterized and studied for their full range of cosmeceutical benefits such as skin whitening, moisturizing, photoprotection, antiaging, antiwrinkle, anti-melanogenic, and antioxidant activities as well as in the treatment of pruritus (caused by acne, eczema, dermatitis, hives, psoriasis), photoaging, and skin pigmentation disorders (hypopigmentation due to the absence of melanocytes and hyperpigmentation caused by skin irritation or metabolic disorders). This review study mainly focuses on marine algae-derived phenolic compounds and their extraction, characterization, and skin cosmetic benefits described in the literature. The present study aims to provide a detailed insight into the phenolic compounds in marine algae.

Résumé :

Cymbidium is one of the most popular genera in Orchidaceae family, commercialized either as loose flowers or as potted plants in floriculture worldwide. The non-marketable parts are typically discarded (e.g., unsuitable flowers, leaves, pseudobulbs, roots), generating an enormous quantity of unutilized biomass. The above by-products were studied through phytochemical analysis and investigated for their dermo-cosmetic potential. The initial antioxidant, anti-tyrosinase, anti-elastase, and anti-collagenase assays of the total extracts indicated that the pseudobulb and root ethyl acetate extracts were the most potent. Those extracts were then submitted to chromatographic separation leading to the isolation of 16 secondary metabolites (four phenanthrenes, three 1,4-phenanthrenquinones, three dibenzyls, two phenolic acid derivatives, two sterols, one dehydrodiconiferyl alcohol derivative, and one simple phenolic compound), including 6-hydroxy-5,7-dimethoxy-1,4-phenanthrenequinone (cymbisamoquinone), which was identified as a new natural product. In parallel, 48 metabolites were identified by UPLC-HRMS analysis of the extracts. The biological evaluation of the isolated compounds revealed that gigantol and tristin present important anti-tyrosinase activity, while bulbophyllanthrin, 3-hydroxy-2,4,7-trimethoxy-phenanthrene, marylaurencinol A, 5-hydroxy-2-methoxy-1,4-phenanthrenequinone, and ephemeranthroquinone B show dose-dependent anti-collagenase activity. In contrast to isolated metabolites, which may act selectively on specific enzymes, the initial total extracts exhibited inhibitory activity against tyrosinase, elastase, and collagenase enzymes, thus showing better prospects for use in dermo-cosmetic formulations.

Résumé :

La production d’huile d’olive génère un volume important d’un sous-produit produit polluant : des eaux de végétation appelées margines, générées à hauteur de 10 à 30 millions de m3 chaque année. Leur importante charge organique et notamment leur taux en polyphénols élevé rend leur traitement complexe. De nombreux chercheurs tentent donc de valoriser les margines, et notamment leurs polyphénols, plutôt que de les éliminer. Un séco-iridoïde des margines pour le moment peu étudié et à forte valeur ajoutée présente une activité antioxydante et anti-inflammatoire prometteuse vis-à-vis de l’hydroxytyrosol, polyphénol aujourd’hui le plus étudié des margines. Nous nous sommes donc intéressés dans cette thèse à la valorisation dermo-cosmétique de ce composé. Dans un premier temps, le composé d’intérêt a été dosé dans des margines de différentes variétés, maturités, méthodes d’extraction et années de récolte à l’aide d’une méthode de dosage par UHPLC-UV-MS validée selon les recommandations de l’AOAC et de la FDA. Nous avons pu mettre en évidence que la variété était le paramètre impactant le plus le contenu en composé d’intérêt dans les margines. Un extrait du composé d’intérêt pur à 93% a été produit à partir de margines grâce à une extraction liquide/liquide Eau/Dichlorométhane suivie par une purification. Dans un second temps, l’activité anti-âge du composé d’intérêt a été évaluée sur le modèle animal autorisé en cosmétique Caenorhabditis elegans. Sa capacité à augmenter l’espérance de vie moyenne de C. elegans et sa résistance au stress thermique et oxydant ont été mises en évidence. Il a également été identifié que cet effet passait par une activation de Sir-2.1/SIRT1 et DAF-16/FOXO, des acteurs majeurs de la réduction du stress oxydant dans les cellules. Enfin, l’absorption cutanée du composé d’intérêt a été évaluée in vitro sur peau de cochon à l’aide de cellules de Franz. Cette analyse a été compliquée par la réactivité particulière du composé d’intérêt au contact de certains acides aminés et nécessitera de futures adaptations
The production of olive oil generates a large volume of olive mill wastewaters (OMW’s) a polluting by-product of which an estimated 10 to 30 million m3 are generated each year. The high organic load of OMW’s, and in particular their polyphenol content complicates their disposal or treatment. Much research has consequently focussed on finding methods to valorise rather than eliminating OMW’s, with considerable attention being paid to the recovery of bioactive polyphenols. Olive mill wastewaters contain large amounts of a secorioidoid to which relatively little research attention has hitherto been paid. It has promising antioxidant and anti-inflammatory activities which are greater than those of hydroxytyrosol, the most widely studied polyphenol of OMW’s today. The aim of the work presented in this thesis was to investigate the dermo-cosmetic properties of this compound. It was first analysed in olive mill wastewaters of different varieties, maturities and harvest years by various extraction methods with quantification by UHPLC-UV-MS. The method was validated according to the recommendations of the AOAC and FDA. We demonstrated that the variety was the parameter having the greatest impact on the compound of interest content of OMW’s. An extract with 93% purity of the compound of interest was obtained from wastewaters using liquid/liquid extraction with dichloromethane followed by purification. In a second step, the anti-aging activity of the compound of interest was evaluated on the animal model authorized in cosmetics, Caenorhabditis elegans. The ability of the compound of interest to increase the average life-span expectancy of C. elegans and its resistance to thermal and oxidative stress was demonstrated. It has also been shown that this effect involves activation of Sir-2.1/SIRT1 and DAF-16/FOXO, major players in the reduction of oxidative stress in cells. Finally, the cutaneous absorption of the compound of interest was evaluated in vitro on pig skin using Franz cells. This analysis was complicated by the particular reactivity of the compound of interest in contact with amino acids, an observation which will be explored in depth in future research projects

Résumé :

Des voltampérogrammes réalisés directement dans les crèmes dermo-cosmétiques, milieux conducteurs, permettent d'évaluer la capacité antioxydante globale du produit disposé en masse ou en fine couche, analogue à celle appliquée sur la peau. L'identification et la quantification d'espèces nécessitent la fabrication de crèmes de compositions différentes. Les dispositifs conçus et mis au point pour suivre la variation de ces propriétés dans le temps révèlent des fluctuations des propriétés antioxydantes globales et des concentrations des constituants, explicables par des réactions chimiques couplées. Des interactions entre constituants de la crème ont été mises en évidence et précisées : entre l'α-tocophérol et l'ascorbate à une interface liquide/liquide entre le méthylparaben et l'ascorbate en phase aqueuse. Ce travail a par ailleurs abouti à la proposition d'un outil pour le contrôle du procédé de fabrication des crèmes
Voltammograms carried out directly in the dermo-cosmetics creams, conducting media, enable to evaluate the total antioxidant capacity of the product disposed in bulk or in a thin coating, similar to that applied on skin. Identification and quantification of species require the manufacture of creams with different compositions. The devices designed and developed in order to follow the variation of these properties as a function of the time; experiments reveal fluctuations of the total antioxidant properties and of the concentrations of the components, explainable by coupled chemical reactions. Interactions between components of the cream were highlighted and specified: between α-tocopherol and ascorbate at a liquid/liquid interface between methylparaben and ascorbate in aqueous phase. In addition, this work gave the basis of a process for the control of the cream production
