Tests cutanésIndex. décimale : 668.5 Parfums et cosmétiques Résumé : White it may seem cynical or flippant of me to approach this point from a marketing perspective — seemingly professing the similar objective performance of ail creams that subjective ability merely depends on the epistemological background of each consumer's belief in which brand, product or ingredient best works for them — I feel this would be unfair and untrue. But this is also not the point of this article.
What I hope to have commented upon is the cosmetic industry's inherent relation to ail areas of the global business environment whether it be a region's economic, legislative or social standing in a two-way relationship. And thus, because of the way in which consumer activity is affecting the personal care industry and vice versa, it is pivotai to deive into the minute details that ultimately affect the larger picture for a product, brand and company's business success and the way this affects the macro-environment in conjunction with ail other competitors. And so understanding the consumer product testing process, from how and when to use formulation-led bibliographic claims compared to in vivo clinical assessments, is decisive in being able to budget and plan a single SKU's launch as well as to forecast the intended demographic's behaviour in response to the brand's market angle and approach; furthermore this understanding and proactivity will allow a company to internally audit the path of their implemented strategy.
Thus, finally, we can see how mastering the understanding of the interchange between testing procedures and a product's advertising claims will inevitably allow for the most efficient and honed product to be launched to the correct market to maximise profit and brand positioning in the quest for enhancing a company's foothold in our ever-growing and ever-popular global industry.Note de contenu : - A need for legislation - cosmetics regulation 2013

Résistance à l'humidité:Résistance à l'eauIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The Dow Corning Tester w•as introduced as an alternative for measuring water resistance in leather hecause the number of flexes to produce a leak was found to he approximately one quarter of the number required on the Maeser Tester. An investigation was conducted to determine how three possible ways of mounting specimens in the Dow Corning 'l'ester would affect water penetration. The results show that w•ater penetration is achieved faster with the Dow Corning Tester than with the Maeser Tester only when the specimens are mounted with their walls parallel tu each other during maximum extension. The gaskets prescrihed for use with the Dow Corning Tester are not essential and need not be used. When a four-by-four inch specimen is mounted to form a pouch with a middle fold before the machine is turned on, the specimens are compressed, slowing down the rate of water penetration to the extent that no saving in time is realized, compared to the Maeser Tester. In fact, with some of the leathers tested in this manner flexing had tu he terminated after 100,000 cycles because no leakage occurred, as is frequently ohserved on the Maeser Tester. The precision of the methods in which end points were reached with unahraded samples was hetter than expected, with the coefficients of variation ranging from 29 to 67 percent, compared with 100 percent termed "not unusual" in the description of the standard method issued by the American Society of Testing and Materials.
Final tabulation shows that for the water-resistant upper leathers examined the mean ratio of the number of flexes till leakage in the Maeser Tester to the number of flexes till leakage in the Dow Corning l'ester was in the vicinity of 2.5, which is somewhat lower than previously reported.Note de contenu : - Equipment

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Four different plant material extracts containing flavonoid compounds were prepared with fruits of Lycium ruthenicum Murray (LRM) and Vaccinium spp. (VS), Ginkgo biloba L. (GBL) leaves and grape seeds. On the basis of several characterisation, these extracts were then used for functionalising waste wool fibres by an exhaustion dyeing process. Content of deposited flavonoid compounds and aqueous chromium(VI) reductive removal capacity of four plant material extract dyed wool fibres were investigated and compared. The results indicated that LRM and VS extracts contained more flavonoid compounds (0.12-0.15 mg ml−1) than the other two extracts (0.06-0.08 mg ml−1), which led to high content of deposited flavonoid compounds and strong chromium(VI) reductive removal performance of their dyed wool fibres. Importantly, 0.10 mmol L−1 of chromium(VI) species could be almost completely removed by fallen GBL extract dyed wool fibre from water by increasing content of deposited flavonoid compounds up to 8.0 mg g−1, which offer a novel strategy to produce cost-effective, environmental-friendly and renewable chromium(VI) removal material based on waste control by waste.

Ingrédients cosmétiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - OBJECTIVE : The objective is to develop a natural cosmetic ingredient from Eryngium maritimum regarding the high interest of consumer in these ingredients for cosmetic use.
- METHODS : Five eco-friendly techniques of extraction were applied to Eryngium maritimum aerial parts among conventional reflux extraction (with green solvent) and alternative techniques (supercritical fluid extraction (SFE), microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE) and ultrasound combined with microwave extraction (UAE + MAE)). Several criteria were evaluated to allow the optimal choice for an industrialized ingredient: yield of extraction, chemical composition and biological activities such as antimicrobial, antioxidant, anti-collagenase and anti-tyrosinase activities. The extracts were analysed by liquid chromatography mass spectrometry (LC-HRMS), and the hierarchical Pearson classification (HCA) allowed to highlight the group of metabolites preferably extracted depending on the technique of extraction used.
- RESULTS : The biological results highlight that SFE and 80% ethanol reflux extracts have the best responses to biological activities such as antimicrobial, depigmenting and antioxidant activities, followed by water reflux extraction. Their activities might be due to the presence of different groups of metabolites favourably extracted by these techniques.
- CONCLUSION : Among these extractions, water reflux extraction provided the optimal results considering the compromise between extraction yield and biological activities for the development of a cosmetic ingredient.
