VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : To quantify the effect of preweathering of new wood surfaces on subsequent finish performance, unfinished wood siding was exposed outdoors for four or eight weeks. Following this preweathering, the specimens were finished with a variety of finishes and placed outdoors again for several years (weathered). The finished specimens were evaluated annually to determine the effect of preweathering on finish performance. The durabilities of 30 different finish systems, consisting of six finishes and five substrates, were evaluated over a five-year period. The wood species were primarily hardwoods and dense softwoods. For these dense species, which weather slowly, a few weeks of preweathering decreased paint performance. The effect of preweathering varied depending on the lenght of time the siding was preweathered, wood species, surface roughness, and finish. The results of the weathering were compared with the results of adhesion testing of similar panels preweathered before finishing.

Tests d'efficacitéIndex. décimale : 667.9 Revêtements et enduits Résumé : Several methodologies are available to evaluate the efficacy of in-can preservatives also known as wet-stat industrial biocides. They are intented to prevent microbial spoilage of waterbased paints. Test conditions - including the inoculum type, the concentration and the sampling schedule - differ among these methodologies. The results obtained using the different methodologies may not be in agreement. A set of conditions considered to be critical for in-can efficacy test design is recommended after reviewing the different methodologies. In-can efficacy evaluations that incorporate the conditions described above yield realistic biocide and biocide use-level recommendations.

Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Increased attention has been focused on the objective evaluation of cosmetics to improve the performance of cosmetics and to fulfill the requirements in the European legislation demanding proof of certain product claims (The Council of the European Communities 1993). The following is an effort to provide some insights into the methodologies of efficacy studies which may facilitate establishing a valid study design, analysis and report. Clear language, accurate observations and reliance on evidence rather than on speculation are believed to enhance consumer confidence in cosmetics and be in the best interests of the cosmetic industry.

Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Research on the skin microbiome is a fascinating and trendy topic and will probably evolve further. However, despite the intense research, the microbiome shows huge inter- and intra-individual variation and there has been until now no scientific consensus on its perfect composition.
An aspect that still needs more research effort is the influence of cosmetic products on the resident microbiome. What is happening in the microbiome realm when applying oily formulations on skin areas that by nature do not have high sebum production and feature an adapted healthy microbiome ? How can we ensure that added microorganisms will survive in the microbial communities on the skin surface ?
And might it be possible that the well¬meant application of probiotic products might have an adverse effect on the skin microbiome, destroying the adapted balance by adding more species of certain bacteria ?
The findings that the skin microbiome is essential for skin health pose a challenge to cosmetic industry to develop new products that not only consider traditional skin types such as oily or dry but to widen their understanding of skin types to certain microbiome types.
Since the daim behind using formulations modifying, enhancing or feeding the microbiome, is the improvement of skin health and especially the strengthening of the skin barrier function, traditional biophysical testing methods and imaging are well-suited to substantiate health-related claims of such products.Note de contenu : - Fig. 1 : Skin is a natural habitat for a rich variety of microorganisms
