Mélanges (chimie)Index. décimale : 667.9 Revêtements et enduits Résumé : Wood colored internally by fungi has long been used by woodcrafters and artisans as a substitute for synthetic dyes. Recent advances in the field of spalted wood have led to methods by which the fungal dyes can be extracted from either a fungal solution or colonized wood and then reapplied to clear wood. This takes the “guess work” out of spalting, as well as the time necessary for fungal colonization; however, it requires organic solvents like dichloromethane, which are toxic and not readily available to consumers. Herein, the authors show that the dyes can be successfully carried and blended together (to increase the range of colors) in a range of natural oils. The blue–green dye of Chlorociboria species, called xylindein, carried best in raw linseed oil, the red dye of Scytalidium cuboideum performed best in Danish oil, although more dye could be carried in raw linseed oil, and the yellow dye of Scytalidium ganodermophthorum performed best in walnut oil. The ability to carry and mix these dyes in easily purchased, nontoxic oils opens up their use to woodworkers who seek to follow the traditions of spalted wood, but do not have the skills or time to work with live fungal cultures or fungal dyes suspended in toxic organic solvents.

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)

Protection contre le rayonnement ultravioletIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Ceramides are lipids that naturally occur in the hair strands. The hallmark of a healthy hair strand is a tightly packed cuticle layer which maintains its strength, elasticity, and shine, without it, hair becomes vulnerable to unwanted damage. The main purpose of ceramides is to 'glue' cuticle layers together to ensure the hair will lay flat and remain intact. Although ceramides occur naturally in the hair, sun exposure (UV light), over time, depletes them leading to raised cuticles, resulting in the loss of moisture, causing the hair strands to become fragile. Oat Cosmetics have developed Oat Lipid e (INCI name: Avena sativa (oat) Kernel Oil), a superior oat oil with a unique lipid profile and tested its efficacy to protect the ceramide content in hair after UV exposure, which effectively improves hair shine as well.

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Consumers are becoming more familiar with dietary supplements for inner beauty and this trend has been growing overtime. The percentage of consumers buying ingestible skin care, just in the UK and France, has risen from 14% in 2017 to 30% in 2022, a Lycored survey revealed. In Germany, a dm survey conducted through “unser dm”, the dm online community, revealed that products for skin, hair and nails are the third favorite dietary supplements category, behind vitamins & minerals and cold products. This market has specific requirements though that still need to be addressed to successfully meet customer needs. Note de contenu : - The beauty-from-within and the inside-out beauty concepts

Réticulation (polymérisation)Index. décimale : 667.9 Revêtements et enduits Résumé : Exploring renewable materials to replace petroleum-based building blocks for advanced coatings has been a major thrust area for researchers for the development of eco-friendly and sustainable products. For the last few decades, there has been significant interest among coating researchers around the world to design water-based polyurethane dispersions (PUDs) that can be cured at ambient conditions. Polyurethanes are the most versatile polymers, exhaustive studies have been reported and more details of all aspects of their properties and uses are given. Vegetable oil-based polyurethanes are used in various fields from coatings to elastomers including smart biomaterials. This paper comprises overview in recent developments on the preparation of biobased polyols from plant oils, covering from the general epoxidation as welI as to high light the properties of polyurethanes obtained from them.

Stabilité thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Natural oils contains high percentage of unsaturated fatty acid and can be converted into epoxy fatty acid by epoxidation process. The Natural oil was first epoxidized using hydrogen peroxide (H202) and acetic acid. Epoxidized natural oils has emerged as an interesting concept as they obtained from sustainable, renewable natural resoui ce and are environmental friendly. For the curing purpose the epoxidized oils are also treated with a biobased acid such as citric acid (CA) and tartaric acid (TA) forming Bioepoxy CA and Bioepoxy TA. A thermogravimetric analysis revealed that thermal stability of bioepo) CA and bioepoxy TA resins were comparable with the petroleum based epoxy resins trimethylolpropane triglycidyl ethi based (P1-epoxy) and bisphenol-A diglycidyl ether based (P2-epoxy). The aim of the review is to study the kinetics of th, reaction involving d uring Epoxidation and Curing process. Note de contenu : - Vegetable oils : structure, composition, properties
