VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : Poly(vinylidene fluoride) (PVDF) clearcoats have been used for over 20 years to extend the service life of architectural coil coatings, and new waterborne PVDF technology now provides a low-VOC route to extend the same protective properties to hear-sensitive substrates of all types, including flexible PVC, base coat paints containing organic pigments, and wood. The use of organic and inorganic UV absorbers can provide a further level of substrates protection in these systems, but for truly-term UV protection, the chemistry of the UV absorber itself within the topcoat also needs to be considered. In particular, we will present some surprising results, comparing the performance of organic and inorganic nanoparticle UV absorbers in PVDF latex coatings.

The effect of the initial metal ion concentration and temperature on the reaction was investigated. Furthermore, the catalytic performance of the resulting metal–wool complexes was evaluated with respect to the dye decoloration efficiency at different pH levels under visible irradiation. The results demonstrated that increasing the initial metal ion concentration and temperature enhanced ion coordination to produce complexes of increased metal content. The obtained Fe–wool showed a higher metal content than the Cu–wool. The light adsorption performance in the UV and visible regions of Cu–Fe–wool is stronger than that of Fe–wool or Cu–wool. Furthermore, Cu–Fe–Wool was found to have a higher catalytic activity than the other two complexes under visible irradiation, especially in the alkaline pH range.

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
- Particle size and related properties
- Sample preparation - solvent choice
- Energy input
