Vieillissement cutané -- PréventionIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Pollution is on the increase worldwide and presents a considerable health risk, especially in urban environments. Skin, as our biggest organ and the barrier between the organism and the outside world, is directly exposed to ambient pollution. We can remove the pollutants by daily cleansing, or protect skin to some extent by applying a physical film to shield it from harmful pollutants, but for full protection we need to strengthen the skin's own barrier function.
We therefore investigated a number of actives for their capacity to increase skin resilience to common airborne pollutants. Based on the results of this skin biological research, we identified actives that demonstrated protective effects and integrated them into a novel concept affording comprehensive anti-pollution protection and relief for vulnerable skin.
Because epigenetic changes may be implicated in changes to phenotypic appearance linked to environmental pollution, we included the new field of epigenetics in out research. Investigation of various potential epigenetic marks revealed that the specific micro-RNA miR-450b-5p, which is associated with cellular senescence, could demonstrate environmentally stressed changes. We therefore conducted a study to investigate the effects of a topical test material on this epigenetic biomarker when stressed with the polycyclic aromatic hydrocarbon benzo(a)pyrene (BaP).Note de contenu : - THE NEED FOR A COMPREHENSIVE APPROACH TO ANTI-POLLUTION SKIN PROTECTION

Protection cutanéeIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The need for year-round skin protection to support our skin against dehydration and external aggressors has inspired BASF to create a solution which offers breathable protection by employing state-of-theart technologies inspired by nature. The biodegradable alternative to polymer film formers, Mimiskinâ„¢, highly resembles human skin and offers all-around care as a skin protector. With its unique melting-point shifting behaviour, it forms a breathable lipid film on the skin, preserving moisture, enhancing complexion, and providing a multi-faceted approach to anti-pollution protection. Mimiskin has been proven to protect skin by reducing the adhesion of pollutant particles, decreasing the penetration of harmful substances into the skin, and enhancing the rinse-off of pollutant particles from the skin.

Sulfures
Travail de rivière (cuir)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Tanneries are often associated with the characteristic and obnoxious "sulfide smell", which is in fact caused by low concentrations of sulfhydric gas, also known as hydrogen sulfide. Levels as low as 0.2 ppm of H2S are already unpleasant for humans and a concentration of 20 ppm is unbearable. As a result, tanneries might be forced to close down beamhouse operations or are forced to re-locate away from populated areas.
As beamhouse and tanning are often done in the same facility, smell is actually the lesser problem. Through human errors, this always holds the danger of mixing acidic floats with the sulfide containing beamhouse float and releasing higher amounts of H2S. At a level of 500 ppm all olfactory receptors are blocked and the gas, therefore, becomes unnoticeable and an exposure for 30 min results in a life threatening intoxication. At a concentration of 5,000 ppm (0.5%), the toxicity is so pronounced that a single breath is enough to cause immediate death within seconds.
Despite all these problems and risks, sulphide has been the preferred chemical for unhairing for more than a century. This can be attributed to unavailable workable alternatives: the use of organic sulphides has shown to be practicable but not really accepted due to the extra costs involved. Unhairing solely by proteolytic and keratolytic enzymes has been tried over and over again but for the lack of selectiveness was difficult in practice to control. A lot of work has also been invested in oxidative unhairing, but until today it is very limited in its use as it is hard to get consistent results.Note de contenu : - The unhairing process
