The two coatings, natural indigo-pigmented boat varnish and outdoor paint, were exposed to cycles of ultraviolet light, water condensation and water spray for 40 days in a QUV test chamber. Synthetic indigo and commercial ultramarine pigment were employed as reference materials. The effects of artificial weathering on the coatings were evaluated with CIELab parameters, as well as visual inspection. Coating and pigment stability during artificial weathering were studied with reflectance spectrometry, hyperspectral imaging technology and Fourier Transform–infrared spectroscopy. According to the results, coatings with indigo proved to be more resistant to visual and spectral changes than unpigmented or commercially pigmented coatings.

Sécheresse cutanéeUne xérose est un dessèchement de la peau.
Elle peut avoir différentes causes, comme certaines pathologies (dermatite atopique aussi appelé eczéma atopique), des carences, notamment en Vitamine A, ou des facteurs externes, comme les contacts avec des substances irritantes ou le traitement par certains médicaments.
Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : To formulate a consumer-acceptable cosmetic product, numerous demands have to be fulfilled, and as the most important, efficacy (both real and perceived), adequate aesthetic (visual perception) and all sensorial characteristics have to be achieved. In this study, four model water-in-oil creams intended for hand care, varying in one emollient component, were submitted to rheological, sensory and textural characterization, and their efficacy was evaluated in in vivo study on human volunteers. Our results indicate that certain alteration restricted to the oil phase induced a change in all investigated characteristics, showing that each instrumental measurement can be used as a sensitive tool in the characterization of cream samples. Regarding the correlation between physical measurements and certain sensory attributes, it is possible to formulate a product with specific sensory characteristics by using pre-defined rheological or textural parameters. To obtain a complete sensory profile of a cosmetic product, a detailed sensory evaluation should be carried out according to the existing standard practices, which are both time- and money-consuming. However, a modified sensory study could be useful for fast in-line screening along with instrumental characterization of a novel cosmetic emulsion product and could be particularly helpful in the process of distinguishing a single formulation from several differing in one component.

Tannage combinéLe tannage combiné se dit des tannages qui allient deux familles ou genre de tannage pour obtenir un résultat additionnant les qualités complémentaires des tannins mis en œuvre par exemple Chrome-Végétal ou Chrome-Synthétique
Tannage organiqueIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In this study we present an industrial-scaled tanning process intended to replace chrome tanning in the production of high quality bovine shoe upper leathers using a combined tannage based on a mimosa and oxazolidine as crosslinking agent. This paper reports the best recipe developed and the properties of the leather obtained. The various test results and scanning electron microscopy (SEM) observations which were used as investigative methods to follow the tanning process steps and to better understand the cross-linking mechanisms, are detailed together with the characterisation of the effluents. The leather obtained is characterised by a good hydrothermal stability coupled with good physical and technical properties which allow it to easily comply with the standards required for high quality chromium-tanned bovine upper leather. The results obtained suggest that this tannage is a promising alternative to traditional chrome tanning. Note de contenu : - Interactions between the collagen structure, mimosa, and oxazolidine

Recyclage (déchets, etc.)Index. décimale : 677 Textiles Résumé : During production of carbon rovings and their further processing into fiber reinforced composites, rejects of carbon filament production and edge cutoffs of crimp and non-crimp fabrics are obtained. These rejects are used for generating new, high-quality materials, which are suitable for applications in fiber reinforced composite technology. Within the CAMISMA project an aerodynamic nonwovens production technology was developed and used to continuously produce C-nonwovens. One focus lies on the comminution and characterization of C-fiber length. The comminution process was tested using 3 different cutting units. To determine a method for C-fiber length characterization, 3 different methods were compared. Note de contenu : - Input material
