NettoyageIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : When the sanitary ware "ceramicplus" was launched it was one of the first product in consumer market that offered a surface based on nanotechnology. "ceramicplus" is a ceramic material that is modified by sol-gel methods, the so called wet-chemical nanotechnology thus creating a material of very low surface energy which results in a particularly dirt-repellent and easy-care surface. A further innovative surface is called "activecare". This ceramic glaze contains small quantities of antibacterial silver ions which prevent the build-up of bacteria and ensures hygienic cleanliness. Independent tests by renowned research institutes have verified the properties and long-term effect of "ceramicplus" and "activecare". Because of its water- and dirtrepellent properties "ceramicplus" requires minimum care without influencing the established good properties typical of ceramic materials. The roughness and hardness of ceramicplus is not significantly different from those of conventional ceramic glaze for sanitary ware. Scrubbing tests have proven that only the long-run use of highly abrasive cleaning agents – like scouring powder – may scratch the surface and impair the properties of "ceramicplus" as well as conventional ceramics. Thanks to the easy-care properties of these functionally modified ceramic surfaces such aggressive cleaning agents are not required for cleanliness.

Caractérisation
CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).

Textiles et tissusIndex. décimale : 667.9 Revêtements et enduits Résumé : Developing a scalable and cost-effective coating process is critical to manufacturing cotton-based hydrophobic antimicrobial fabric for various commercial applications. This paper describes a scalable, cost-effective coating process that is compatible with the existing industrial finishing processes of fabrics. In this process, the fabric is continuously dipped in water-based silver salt and the reducing agent solution to impart silver particles on the fiber surface to produce different coated samples. The process is tuned to minimize process cost and material cost and maximize the antimicrobial effectiveness and durability of the fabric. This paper also introduces an easy protective coating technique with silicone binder of the antimicrobial fabric that improves the durability and hydrophobicity of the antimicrobial fabric without sacrificing the comfort properties of textile fabrics. In the presence of silicone binder, the samples show significant antibacterial effectiveness against two microorganisms, gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacteria. Qualitative assessment is carried out to evaluate the antimicrobial properties of the silicone encapsulated silver particles-coated fabrics. Moreover, among the silver-coated fabrics of different cycles, silver nanoparticles (AgNPs) are deposited in the 1 cycle of silver-coated fabric and the average particle size deposited onto the fiber surface is 65.52 ± 2.71 nm. After silicone encapsulation, among all encapsulated samples, 1 cycle of silver-coated silicone encapsulated sample shows the best result in terms of antimicrobial efficacy where silicone encapsulated 1 cycle silver-coated sample shows around the zone of inhibition 0.53 and 0.25 mm and encapsulated 2 cycles silver-coated sample shows the zone of inhibition 0.14 and 0.06 mm for S. aureus and E. coli, respectively. Coated fabrics with and without silicone encapsulation are characterized by scanning electron microscopy and energy-dispersive X-ray spectroscopy.

BactériocinesLes bactériocines sont une famille de peptides ou protéines synthétisés naturellement par certaines bactéries. Une bactériocine consiste généralement en un composé protéique de 20 à 60 acides aminés.
Les bactériocines ne sont pas des antibiotiques mais elles possèdent des propriétés antibiotiques :
- Elles peuvent être bactériocides, c'est-à -dire éliminer certains micro-organismes.
- Elles peuvent être bactériostatiques, c'est-à -dire inhiber la croissance de certains micro-organismes.

Cuirs et peaux de moutonsIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Bacteriocins, produced from a wide variety of microorganisms to inhibit or kill different species of bacteria, have received increased attention in different industries. Hence, bacteriocins produced from moderately halophilic skin isolates were examined to demonstrate their inhibitory effect against enzyme-producing (protease or lipase) skin isolates. Eleven identified skin isolates, obtained from salted goat and sheep skins, were used as test isolates. Ten of these isolates (Halomonas halodenitrificans, Halomonas halmophila, Salimicrobium salexigens, Gracilibacillus dipsosauri, Salinivibrio costicola subsp. alkaliphilus, Halomonas venusta, Planococcus rifietoensis, Marinococcus tarijensis, Halomonas eurihalina, Staphylococcus arlettae) showed antimicrobial effect against each other. Although Halomonas halodenitrificans, Salimicrobium salexigens, Halomonas venusta did not produce enzyme, the other isolates produced protease or lipase enzymes. While bacteriocin produced from Halomonas halodenitrificans was found to be effective against enzyme-producing Gracilibacillus dipsosauri, Planococcus rifietoensis and Halomonas eurihalina, bacteriocin of Salimicrobium salexigens was effective against enzyme-producing Salinivibrio costicola subsp. alkaliphilus, Marinococcus tarijensis and Halomonas eurihalina. Bacteriocin of Halomonas venusta was effective against enzyme-producing Halomonas halmophila, Marinococcus tarijensis, Halomonas eurihalina, Idiomarina loihiensis and Staphylococcus arlettae. The maximum bacteriocin production of these skin isolates was obtained at 37°C, pH 7.0, and 10% salt concentration. Antimicrobial activities of the bacteriocins against all test isolates were detected at 10°C-60°C, pH 6.0-8.0 and 3%-20% salt concentrations. Antimicrobial activities of all bacteriocins against test isolates were not detected after the treatment with proteinase K. Minimal inhibitory concentration (MIC) values of the bacteriocins against the test isolates were detected as 1/2, 1/4 or 1/8. Scanning electron micrographs of sheepskins showed that sterile bacteriocins of Halomonas halodenitrificans, Salimicrobium salexigens, Halomonas venusta may be used in leather industry to prevent the growth of protease and lipase producing moderately halophilic bacteria.

SébumIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Derived from the green fractionation of mango leaves, Mangixylâ„¢ (also referred as 'Mangifera Indica leaves active') is an effective cosmetic ingredient that is microbiome-friendly with proven efficacy targeting oil skin through sebum regulation. The cosmetic innovation activates specific receptors of gene’s pathway normally regulated by the highly potent retinoic acid.
In an era where sustainability and traceability are top of mind for consumers, the sourcing story of Mangixylâ„¢ highlights our commitment to our Company Purpose. The mango leaves are collected in collaboration with the Association Bendia, based in Koro village (Burkina Faso, Africa). The association is a women-led initiative to contribute to the improvement of the living conditions of the community. Thus, Mangifera Indica leaves active is an ingredient good for the consumers, good for the planet and good for the people.This ingredient aims to relieve consumers from the discomfort caused by oily skin. It activates some receptors of the retinoic acid-regulated genes pathway and decreases in vitro, ex vivo and in vivo the synthesis of lipids on all skin ethnicities. Additional clinical data showed efficacy against prone-to-acne skin, and on the regulation of sebum on scalp hair. Amidst the current COVID-19 crisis, it also provides an effective response to the "maskne" phenomenon which has been gaining momentum lately.Note de contenu : - Sourced responsibly
