Indeed, plenty of biological damages are induced by UV light source and adapted protections are required in order to reduce them. This work presents the different sun protection assessment brought by sunscreens, fabrics and lenses. In each case, a specific name and method has been developped with, respectively SPF (Sun Protection Factor) for sunscreen, UPF (Ultraviolet Protection Factor) for fabrics and E-SPF (Eye-Sun Protection Factor) for lenses.

Titre : Anti-odor properties of sodium bicarbonate assessed by sensory evaluation Type de document : texte imprimé Auteurs : Sophie Mouzon, Auteur ; Jeanne Perez, Auteur Année de publication : 2020 Article en page(s) : p. 44-48 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Analyse de variance En statistique, l'analyse de la variance (terme souvent abrégé par le terme anglais ANOVA : ANalysis Of VAriance) est un ensemble de modèles statistiques utilisés pour vérifier si les moyennes des groupes proviennent d'une même population. Les groupes correspondent aux modalités d'une variable qualitative (p. ex. variable : traitement; modalités : programme d'entrainement sportif, suppléments alimentaires ; placebo) et les moyennes sont calculés à partir d'une variable continue (p. ex. gain musculaire).
Ce test s'applique lorsque l'on mesure une ou plusieurs variables explicatives catégorielles (appelées alors facteurs de variabilité, leurs différentes modalités étant parfois appelées "niveaux") qui ont de l'influence sur la loi d'une variable continue à expliquer. On parle d'analyse à un facteur lorsque l'analyse porte sur un modèle décrit par un seul facteur de variabilité, d'analyse à deux facteurs ou d'analyse multifactorielle sinon. (Wikipedia)

Odeurs -- Lutte contreIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Nowadays, more and more people are concerned about the safety and carcinogenicity of some components used as antiperspirants inside deodorant formulas, for instance aluminum salts [1]. The consumers are searching for a smooth alternative to this kind of ingredients that would not impede perspiration. SEQENS Mineral Specialties carried out a sensory analysis to compare the anti-odor efficacy of three different formulas of roll-on deodorants: one with sodium bicarbonate, one with anti-odor active and one with placebo. 24 subjects have participated in the study and a trained jury of five people has assessed the perspiration smell intensity, and the hedonic value of the smell 8 and 12 hours after the standardized application. Furthermore, the formulas were hidden (masked review). This study allows to prove scientifically that sodium bicarbonate has efficient anti-odor properties and can be an alternative to antiperspirants for the formulation of deodorants.

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Products with film-forming effect, or 'second skin', which guarantees an immediate protective effect after application, is a highlight, especially when composed of natural ingredients. Thus, the objective of this study was to evaluate the immediate film-forming effect on skin of a gel and emulsion formulations added with Kappaphycus alvarezii and Caesalpinia spinosa extracts through biophysical and skin imaging techniques, especially with the Reflectance Confocal Microscopy (RCM).
- Methods : The measurements were done in the forearm region before (baseline) and 1 h after of application of the developed formulation and its control. The parameters related to the stratum corneum water content, transepidermal water loss (TEWL), cutaneous microrelief and morphological and structural characteristics of the epidermis were analysed through the following biophysical and skin imaging techniques: Corneometer® CM 825, Tewameter® TM 300, Visioscan® VC98 and Vivascope® 1500, respectively. A sensorial analysis was also performed to study how the formulations were perceived on the skin.
- Results : The obtained results showed that the active ingredient under study allows the film formation on the skin surface, leading to a reduction of TEWL and skin desquamation. The obtained images from RCM showed a reduction of furrows on the skin surface and a film formation after a single application of the formulations. However, these effects were more pronounced in the emulsion formulation, which suggests a synergistic effect of the active ingredient under study with the emollients of formulation composition. This result was also observed in the sensorial analysis, as both formulations added with the active substance were well evaluated.
- Conclusion : The presence of Kappaphycus alvarezii and Caesalpinia spinosa extracts in the studied cosmetic formulations, enabled a film formation on a skin surface, bringing benefits as a reduction of transepidermal water loss and skin desquamation, as well as a furrows reduction and an improvement of stratum corneum after 1 h of application. Finally, the skin imaging techniques can be suggested as an excellent tool to evaluate a film-forming effect of cosmetic formulations.Note de contenu : - INTRODUCTION : Objective

Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : A new approach for evaluating the local electrical properties of organic coatings has been proposed. It was performed with contact mode atomic force microscopy (AFM). A current response signal was measured when a single-frequency voltage perturbation was applied between AFM tip and coated metal. Suitability of the proposed technique has been presented on the representative acrylic coating degraded by two different factors—UV radiation and electrolyte exposure. It was possible to disclose the early stages of the coating deterioration, to spatially localize defective regions, and to observe distinctly different modes of the coating degradation as a result of exposure to various degradation factors.

Wet-blue (tannage)Peau tannée au chrome (le chrome donne une couleur bleue)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : N-(2-Hydroxy) Propy1-3-Trimethyl Ammonium Chitosan Chloride (HTCC) has better water-solubility than Chitosan (CS), and ils solubility no longer depends on the change of solvent pH, The minimum bactericidal concentration (MBC) of HTCC to Escherichia (E. coli) is 6g/L whereas the MBC for CS is 9g/L, and the value for Staphylococcus aureus (S. aureus) is 3g/L_ for HTCC and for CS it is 6g/L. The optimal pH of HTCC to E. coli is 8.0 whereas the optimal pH for CS is 6.0, and the pH value for S. aureus is 7.0 for HTCC whereas that for CS is 6.0. So HTCC has better antibacterial properties and solubility.
Wet-blue cattle hides were treated with HTCC for antibacterial and antifungal effects. The inhibition against Escherichia Poli, S. aureus, Aspergillus figer, Aspergillus flavus and blue mould were investigated through an orthogonal design. The results showed that the treated wet-blue cattle hides possessed good antibacterial and antifungal properties. Correspondingly, the optimum treating conditions of the antibacterial process were a float of 100% with a dosage of 0.4% at pH4.0, below 50°C, reacting for 1.0 hour. The optimized antifungal process was a float of 150% with dosage of 0.2% at pH5.0, below 40°C, reacting for 2 hours.Note de contenu : - MATERIALS AND METHODS : Materials - Water solubility of HTCC - Antibacterial activity of HTCC to Escherichia coli and Staphylococcus aureus - Processing method for hides - Antibacterial test - Antifungal test - Data processing
