ExposomeL'exposome est un concept correspondant à la totalité des expositions à des facteurs environnementaux (c'est-à -dire non génétiques) que subit un organisme humain de sa conception à sa fin de vie en passant par le développement in utero, complétant l'effet du génome.

Peau -- RidesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Claims of personal care evolve following trends and various innovations in the field of the active ingredient development, the finished product formulation and the way both are evaluated, demonstrating their performance. Since the mid-2010s, the cosmetics industry has been gradually leaving the era of anti-ageing behind. Today, most consumers are more in the mood for a 'well ageing', 'slow ageing' or 'pro-ageing' approach.
The philosophy of the 'pro-ageing' movement has sought to remove all 'anti' daims because, according to this concept, women over 50 are not interested in locking younger; they want to look healthy and be honest about their age. Some brands have used the idea of improving the appearance of skin quality and restoring skin comfort. A new vocabulary of renewal, regeneration, plumpness, and Slow' now dominates the language of the beauty industry.
Increasingly inclusive beauty rituals give the opportunity for a pause, counterbalancing stressful, tiring and anxious lifestyles and reducing the deleterious effects of a life that attacks the skin through internat mechanisms or a harmful environment. Eliminate toxins, oxygenate the body, take care of oneself to maintain the radiance and homogeneity of the complexion and a good mood. Beauty then becomes more integrative, it will universalise well-being, the silhouette, sleep quality and lifestyle, resulting in a different look.
Consumers are going to take action to preserve their tonicity, elegance and silhouette. In this quest for mindful beauty radiance, what women expect from cosmetics is emotional pleasure and sensoriality. It is all about supporting the ageing process rather than fighting the signs of ageing, with skincare products supporting a 'pro-longevity' and enhancing.Note de contenu : - Substantiating anti-ageing claims

Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In this study, diethyl bis(2-hydroxyethyl) aminomethyl phosphonate was modified by hexamethylene diisocyanate, and then was utilized to partly replace the isocyanates to prepare hyperbranched polyurethanes (HPU-DPAs). The hyperbranched polyurethanes were then employed in the retanning process of wet blue. The shrinkage temperature, average thickness as well as mechanical properties of leather before and after retanning were acquired. The flammability of retanned leather was measured by cone calorimeter test. The morphologies of wet blue and leather after retanning by HPU-DAP were obtained using a scanning electron microscope. Results showed that the average thickness, tensile strength and elongation at break of leather were all improved after retanning. Retanning by HPU-DAPs can effectively increase flame retardancy of final leather.

Rayonnement ultraviolet AIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The impact of UV-filter combination on the number of free radicals generated in sunscreen formulations and the skin following UV-VIS irradiation was assessed via electron spin resonance spectroscopy using a spin-probing approach. Four UV-filter combinations that differed in their photostability and range of UVA absorbance coverage were investigated. Fewer free radicals were generated in the sunscreen formulation when a photostable UVA filter system was used, compared to a stabilized UVA filter system. Additionally, fewer free radicals were generated in the skin when a sunscreen with long UVA protection extending to the short visible range was used, compared to a sunscreen with minimal UVA protection. This study showed that the photostability of a UV-filter system is central to the generation of free radicals in a formulation, and that long UVA-blue light protection is key for avoiding the generation of free radicals in the skin. A sunscreen product exhibiting both photostable UVA protection and long UVA-blue light protection is therefore the most appropriate choice for protecting against ROS-induced skin damage.

UltrasonsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Shelf-life and crystallization of the dispersed phases of organic melt emulsions are highly influenced by the composition of the emulsion itself. In literature, it is discussed that chemical similarity between the surfactants’ hydrophobic group and the dispersed phase triggers crystallization. This work focuses on the possible effect of foreign gems, such as waxes, on the crystallization of droplets as they may act as active nucleation clusters (ANC) and may also trigger nucleation. ANCs with similar polarity to the dispersed phase were shown to accelerate the crystallization process as well as to lead to crystallization at lower supercooling, which could enable a more sustainable emulsion production as less energy is needed for cooling. Moreover, the same ANCs which increased crystallization speed were shown to improve the storage stability of an organic oil-in-water emulsion. Note de contenu : - Production of melt emulsion
