Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : An attempt has been made to valorise an agroindustrial solid waste in natural textile dyeing as a novel dye source. The dyeing and fastness properties of prina (crude olive cake/pomace) extract were evaluated to fill the gap in this field. This very cheap biomass was utilised (80 g/l) by applying chemical solvent-free aqueous extraction to dye wool fabric with only small amounts (0.2, 0.4, 0.8, and 1.6 g/l) of metallic mordants, namely alum, iron(II) sulfate, copper(II) sulfate, stannous chloride, and potassium dichromate, and avoiding the use of alkali, acid, chemicals, and auxiliaries in dyeing and washing processes. Colour shades of beige, cream, sandy, apricot, straw, cumin, mustard, olive, and khaki were obtained. Significant differences in colour strength and CIELab coordinates were observed, depending on mordant type and mordanting method. Copper(II) sulfate and iron(II) sulfate ensured the most significant colour changes and nuances, the darkest colours, and the best light fastness values. Prina extract itself (without mordant) has a light fastness of 3 (fair) and excellent wash fastness of 4–5, both for colour change and bleeding. Irrespective of the concentration and mordanting method, alum, stannous chloride, and potassium dichromate did not generate a light fastness improvement compared with the control sample. Although good light and wash fastness values have been achieved without mordants, it is necessary to use them to widen the colour gamut and to obtain increased colour strength.

Thé vert et constituantsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : True colour measurements of wastewater samples, in terms of American Dye Manufacturers' Institute values, were used to evaluate the effectiveness of decolourisation of textile wastewater using spent green tea leaf powder waste. Raw wastewater samples with a true colour of 868 ADMI were used in the batch adsorption experiments. Results revealed that the true colour removal efficiency of the raw textile wastewater was high in acidic solution and at high temperature, indicating an endothermic nature of the system. The major functional groups of the green tea leaf powder waste involved in adsorption were identified by Fourier Transform-infrared spectroscopy analysis. Adsorption kinetic data were modelled using the modified Freundlich and intraparticle diffusion kinetics equations. Fitting results of the Langmuir adsorption isotherm showed that the adsorption capacity of the green tea leaf powder waste was 775 ADMI g−1, which is higher than that of powder activated carbon (526 ADMI g−1). The low activation energy values (13.9 kJ mol−1) suggested that adsorption was governed by a diffusion process and the reaction involved a physisorption mechanism. From the perspectives of waste utilisation, remarkable colour adsorption capacity and inexpensive and abundant availability, green tea leaf waste is an attractive alternative for decolourisaton of textile wastewater. Because high temperature favours colour removal, green tea leaf powder can be directly applied in raw textile wastewater treatment.

Économie circulaireL'économie circulaire est une expression générique désignant un concept économique qui s'inscrit dans le cadre du développement durable et s'inspirant notamment des notions d'économie verte, d’économie de l'usage ou de l'économie de la fonctionnalité, de l'économie de la performance et de l'écologie industrielle (laquelle veut que le déchet d'une industrie soit recyclé en matière première d'une autre industrie ou de la même).
Son objectif est de produire des biens et services tout en limitant fortement la consommation et le gaspillage des matières premières, et des sources d'énergies non renouvelables ;
Selon la fondation Ellen Mac Arthur (créée pour promouvoir l'économie circulaire1), il s'agit d'une économie industrielle qui est, à dessein ou par intention, réparatrice et dans laquelle les flux de matières sont de deux types bien séparés ; les nutriments biologiques, destinés à ré-entrer dans la biosphère en toute sécurité, et des intrants techniques ("technical nutrients"), conçus pour être recyclés en restant à haut niveau de qualité, sans entrer dans la biosphère

Schinus terebinthifoliusIndex. décimale : 668.5 Parfums et cosmétiques Résumé : IFF/Lucas Meyer Cosmetics explain why upcycled Schinus terebinthifolia and Lavandula angustifolia extracts are good examples of how the recently created synergy between the fragrance and cosmetic industries can produce original, upcycled and sustainable cosmetic ingredients with interesting effects.
Environmental issues like climate change, increasing pollution and endangered biodiversity have gradually become part of the collective consciousness of society. Consumers are more educated than ever before and their habits and practices are changing. They are thus expecting more from the cosmetic brands they purchase, throughout the whole manufacturing process and supply chain of products.
Recycling, which transforms waste into materials of similar value, is no more considered as the most effective way to dispose of things initially intended to be destroyed. Beyond recycling, a new trend is emerging toward upcycling, a process that rather converts a material into something of greater value than it originally was.
Circular beauty refers to the use of upcycled ingredients obtained by transforming leftovers, by-products, waste or discarded materials from other industries into high-value innovations combined with environmental benefits.
The fragrance industry commonly requires a huge amount of raw materials and generates several tons of waste (spent plant) in the process of extracting essential oils for the making of perfumes. Upcycling of fragrance waste is a step forward on sustainability and opens new opportunities for the cosmetic industry.Note de contenu : - MATERIALS AND METHODS : Extracts - Clinical evaluation of the upcycled - Clinical evaluation of the upcycled Lavandula angustifolia extract

Fibres de sisalLe sisal (Agave sisalana) est une plante de la famille des Agavaceae originaire de l'est du Mexique où on la trouve également sous l'appellation de henequén. Sisal est également le nom de la fibre extraite des feuilles de cette plante. Très résistante, cette fibre sert à la fabrication de cordage, de tissus grossiers et de tapis.
Le sisal est utilisé dans la filière bois pour tous les produits liés destinés au bois énergie et à la trituration (papeterie, panneau de particules). Leur stockage est de courte durée (le sisal est peu durable) et cette fibre végétale peut être mélangée au bois (ne pollue pas la matière comme une fibre synthétique).

Produits antisolairesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Sisal is a common stiff fibre produced around the world, corresponding to approximately 70% of the commercial production of all fibres of this type. The fibres are extracted from the leaves of Agave sisalana, from which approximately 4% of their weight is obtained, with the remaining 96% considered to be residues from the process of the sisal industry. The objective of this work was to obtain a polyphenol-enriched extract from the A. sisalana residue by ultrasonically assisted extraction, characterize it chemically, evaluate in vitro antioxidant activity, and develop safe and stable photoprotective formulations for future application in cosmetic preparations.
- Methods : Ultrasonic extraction of solid plant material was performed using 50% ethanol/water (v/v). The extract was chemically characterized by high-performance liquid chromatography equipment associated with classical molecular networking and evaluated for in vitro antioxidant activity by different methodologies. Ten formulations were prepared, varying the component concentrations and the shear time. The 1.0% sisal extract was incorporated into the most stable formulations, and preliminary and accelerated stability were evaluated. The emulsions were investigated for safety by assessment of primary accumulated dermal irritability and sensitization and a dermatological clinical study of phototoxicity and photosensitization. The photoprotective formulations containing or not containing the extract that were stable after 90 days had their in vivo sun protection factor (SPF), UVA protection factor, critical wavelength, and protection against visible and blue light determined.
- Results : Ultrasound extraction using 50% ethanol/water (EH 50) as an extractor vehicle showed the best yield. The extract exhibited a concentration of phenolic compounds (77.93 mg of equivalent to the standard gallic acid/g) and showed in vitro antioxidant activity. Emulsions without and with 1.0% sisal extract remained stable and safe. The addition of the extract to the photoprotective formulation statistically increased the SPF when compared to the formulation without the extract and offered protection against UVA radiation, critical wavelengths, and absorption of visible and blue light.
- Conclusion : Based on the findings, the solid residue of A. sisalana may be indicated as a component of photoprotective and antioxidant cosmetic formulations.Note de contenu : - MATERIALS AND METHODS : Chemicals - Plant material - Extract production—ultrasound-assisted extraction - Chemical characterization - In vitro antioxidant activity - Photoprotective cream preparation - Evaluation of formulations - Clinical studies on safety in cosmetic products - Assessment of photoprotective activity

CéramidesUn céramide est un sphingolipide résultant de la combinaison d'un acide gras avec la sphingosine via une liaison amide. On trouve de telles molécules en abondance dans les membranes cellulaires, où elles entrent notamment dans la constitution des sphingomyélines. Les céramides ne jouent pas qu'un rôle structurel dans les membranes biologiques, et peuvent également revêtir des fonctions de signalisation lipidique. Leurs actions les mieux comprises vont de la différenciation cellulaire à la mort cellulaire programmée (apoptose) en passant par la prolifération cellulaire.
Les acides gras qui les constituent ont généralement un nombre pair (de 16 à 24) d'atomes de carbone, sont saturés ou monoinsaturés, et sont souvent α-hydroxylés.
La plupart des céramides n'existent pas à l'état naturel si ce n'est comme précurseurs de la biosynthèse des sphingolipides par une réaction d'addition sur la fonction alcool primaire de la sphingosine. (Wikipedia)

Being a heterogeneous group of sphingolipids, they exert an important rote in the construction of the stratum corneum and its barrier ability. The aim of this article is to present a new concept of upcycling ceramide, CeraFluide, which shows high compatibility with skin components thanks to its natural delivery system from olive glycerides. It acts as biocompatible building blocks to joint skin cells, improving skin smoothness and elasticity. It helps to restore the barrier effect, protecting against dehydration, lipoperoxidation, and exposome. Note de contenu : - Skin rebuilder from upcycled olive fractions
