Rayonnement ultraviolet -- AbsorptionIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Objective : To investigate whether sunscreens provide optimal protection by exhibiting a uniform spectral absorption profile throughout the ultraviolet spectrum or by having a spectral profile in which absorption in the UVB waveband is greater than in the UVA region.
Methods : A sunscreen with a flat spectral absorption profile was compared with one of the same SPF in which the SPF to UVA protection was in the ratio of 3 : 1 in terms of protecting against erythema and chronic effects with different action spectra, as well as the total UV burden to the skin.
Results : A sunscreen with spectral profile in which absorption in the UVB waveband is greater than in the UVA region confers no benefit in terms of erythema (and endpoints with similar action spectra) than a sunscreen with the same SPF that exhibits uniform absorption at all wavelengths throughout the UV spectrum. More importantly, the ‘3 : 1 profile’ offers inferior protection when endpoints with other action spectra are considered, as well as resulting in a total UV burden to the skin that is about 5 times higher than sunscreen products showing a flat spectral absorption profile.
Conclusion : It may be tempting to believe that it is beneficial to increase the absorption of sunscreens in the UVB region relative to the UVA to reflect the fact that skin damage is associated more with UVB than UVA exposure. However, this belief is a fallacy and consumers are best served with sunscreens in which the spectral protection profile is uniform at all wavelengths throughout the UV spectrum.DOI : 10.1111/ics.12353 Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27847

Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Several studies highlighted the danger of ultraviolet (UV) irradiation to the human body. 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.

Produits antisolairesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The physical properties of inorganic materials such as titanium dioxide (TiOâ‚‚) and zinc oxide (ZnO) have been utilised in a wide variety of applications for many years. The wide ranging properties of smaller particles of TiOâ‚‚ and ZnO make them ideal for use in sun care products; optimum UV attenuation, coupled with visible transparency results in excellent protection and aesthetic performance.
Recently, despite many scientific studies demonstrating the safety of these ingredients, concerns have been raised that some of the unique properties of these particles may result in adverse effects in cosmetic applications. The Scientific Commitee on Consumer Safety (SCCS) recently published Opinions on TiOâ‚‚ and ZnO in their nano form, which detailed specifications that they believed these materials should meet to be classed as 'safe to use' up to certain concentrations.
Given the importance of the subject area to both cosmetic manufacturers and consumers, it is essential to have an understanding of the methods which are used to examine the physical properties of such nanomaterials.
Many factors affect trhe analysis sample process, from pre-analysis sample preparation to post-analysis data interpretation. This article looks at some of the techniques commonly used tomeasured properties such as particle size,UV protection and photocatalitic activity. Signinificant variations in data can occur if methods are not standardised. The article will also investigate factors such as sample preparation and energy input which can affect results, and highlight the need for correlation of methods with the state of particles in sun care formulations.Note de contenu : - Measuring UV-Vis protection

Tris-biphényl triazineIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Disrupting changes in the suncare field that signal the avoidance of Octocrylene (OCR) and Ethylhexyl Methoxycinnamate (EHMC) in newer sunscreen developments express a real challenge in terms of performance achievement. Ethylhexyl Triazone (EHT) and Bis-ethylhexyloxyphenol Methoxyphenyl Triazine (BEMT) are often used as replacements but the achievement of higher Sun Protection Factors (SPF) requires additional UVB filters. This paper aims to evaluate the benefits of using Tris-Biphenyl Triazine (TBPT) as additional UV filter in comparison to Phenylbenzimidazole Sulfonic Acid (PBSA) and Titanium Dioxide (TiO2) seeing that TBPT is organic like PBSA and particulate like TiO2. We measured the UV absorbance and photostability as product specific performance criteria, and evaluated the risk of the production of free radicals under UV exposure since this is closely linked to photostability and can impact the irritation potential of sunscreens. Their effect in market relevant UV filter combinations was further assessed in view of their contribution to SPF, UVA-PF, blue light protection, and water resistance. We evaluated the ocular acceptability of a sunscreen containing TBPT and proposed solutions for environmentally friendly sunscreens. In this contribution, we show the broadness of the benefits gained in using TBPT in the future production of sunscreens. As a whole, this work reveals the huge potential of TBPT in modern sunscreens.
