Produits antisolairesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Significant research and regulatory attention have been focussed on the potential for some ultraviolet filters (UVFs) to rinse off from beachgoers' skin into seawater leading to exposure to sea life, especially coral reefs. The amount of UVFs potentially rinsed from skin during recreational beach activities has not been well studied, leading to uncertainty about the potential magnitude of aquatic UVF exposure due to changes in sunscreen use patterns. This study quantifies rinse-off of UVFs in sunscreen from skin into synthetic seawater and identifies differences in rinse-off quantity due to formulation type with a goal of informing future modelling efforts aimed at estimating UVF exposure to sea life associated with recreational activities at the beach.
- Methods : UVF rinse-off from skin during recreation in seawater was simulated by applying eight different sunscreen products to porcine skin samples followed by three periods of shaking in synthetic seawater totalling 40 min. The rinsed mass of six UVFs – zinc oxide, titanium dioxide, avobenzone, homosalate, octisalate, and octocrylene – was determined analytically in synthetic seawater and in extractant rinsate from glassware for organic UVFs and compared among formulas.
- Results : Among the 22 UVF-formulation combinations tested, 19 resulted in less than 10% of the applied UVF rinsed from skin. All formulation-UVF combinations where the formula types were water-in-oil (reverse phase) emulsions or anhydrous resulted in 5% or less of the applied UVF rinsed to synthetic seawater. Sunscreens formulated as oil-in-water emulsions yielded higher rinse-off percentages for all UVFs tested, with a maximum of 20% rinse-off of avobenzone in one lotion.
- Conclusion : The potential for sunscreen UVF rinse-off is significantly influenced by formulation and is generally well below the prior assumed rinse-off levels used to estimate risk. Formulation consideration is therefore essential for accurate exposure models used in environmental risk assessment. Anhydrous and reverse phase (water-in-oil) sunscreen formulations tested resulted in lower UVF transfer from skin to synthetic seawater in simulated ocean bathing tests and as a result, are expected to yield lower UVF exposures to sea life. This approach can be used in predictive environmental exposure models to support ecologically safe sunscreen formulation design.Note de contenu : - Table 1 : Formulation types and measured ultraviolet filter (UVF) content for sunscreen formulations in this study DOI : https://doi.org/10.1111/ics.12901 En ligne : https://onlinelibrary.wiley.com/doi/epdf/10.1111/ics.12901 Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=40253

Etiquetage écologiqueTags : Ecolabel Detergent ingredients database Critical dilution volume Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : For comparing the environmental relevance of household and personal care products, the Critical Dilution Volume (CDV) originally developed for the EU Ecolabel of detergents is an often used key criterion. The EU Ecolabel Detergents Ingredient Database (DID) is a publicly available information basis for derivation of product CDV by providing data on key descriptors for the environmental fate and effects of chemical substances used in consumer products. The alterations of the CDV-relevant descriptors in the revised DID list (2004) have led, in many cases, to an unrealistic depiction of the environmental behaviour of product ingredients and to inadequate product evaluations. The paper reports on the framework of and the experiences with a novel DID list developed by an expert group of the German Hauptausschuss Detergentien (HAD) enabling an environmentally more realistic comparison of products.

Environnement -- Etudes d'impactIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Brazil headquartered tanner JBS Couros recently conducted a lifecycle assessment of its sustainable leather concept, Kind Leather. We caught up with Kim Sena, Sustainability Manager at JBS Couros, who was instrumental in the development of Kind Leather, to discuss the importance of LCAs as a vital tool for process improvement. Note de contenu : - It is just over two years ago that JBS launched its Kind Leather concept. Can you explain what Kind Leather is, the key environmental benefits of this approach and how it differs from conventionally made leather ?
- There are tools that aim to evaluate the environmental impact of leather throughout its lifecycle, but JBS developed its own LCA (lifecycle assessment) to measure the impact of Kind Leather. Can you give more details ?
- Kind Leather has recently been added to the Higg Materials Sustainability Index (Higg MSI), run by the Sustainable Apparel Coalition (SAC). Can you share some of those results? Why did JBS decide to follow this path with its LCA ?
- The Higg Index, however, has been viewed as quite controversial and many inside and outside of the leather industry feel that it unfairly scores leather and other natural materials compared to fossil-fuel derived alternatives. What is your view on this ?
- Would you say that LCAs are a useful tool for greater transparency in the leather supply chain and to help change the narrative and negativity around leather ?
- Leather from Brazil is sometimes seen by brands and other industry stakeholders as problematic due to links to deforestation. What is JBS doing to combat this issue ?
- So, with all of the above said, do you feel quite optimistic about the future of leather ?En ligne : https://drive.google.com/file/d/1yAlBOpdpZGAAdv4wPIBXpjl2EjErHpVB/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=36414

Tannage -- Appareils et matérielsIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : As facilities move progressively towards understanding the environmental footprints of their activities, the area of life cycle assessment (LCA) becomes the tool of choice. To remind the reader, the steps of an LCA can be summarised as follows :
- Scope and definition of the LCA
- The life cycle inventory (LCI)
- The life cycle inventory analysis
- Selection of analytical method
- Classification of impact categories
- Characterisation
- Normalisation
- Grouping
- Weighting
- Interpretation
In the LCI, the facility will be looking at the process and will be trying to ensure that it has the numbers that will be required for assessing inputs and gauging the impacts of the outputs. This article will explore why machinery and equipment must be considered part of the LCI.Note de contenu : - How do machines add to LCA ?
