Nanoparticles have shown a positive development due to its own various properties, functionalities and its applications in Cosmetics. One example where consumer expectations grow and the demand increases are UV protectors or sun creams. It was concluded that nanoparticles can be used in cosmetics like sunscreen to increase UV protection and prevent bacteria growth simultaneously. The available products are characterized by advantages and disadvantages of the various UV protection factors, and so far, no single material combines all desired properties. Nanotechnology shows an advantage character as it can be used to change the properties of the finely produced nanoparticles and influences products from various sectors as well as industries for a wide variety of applications, UV protection being amongst them.

SPF boosting ? Naturally, natural ! / Marek Busch in SOFW JOURNAL, Vol. 149, N° 6 (06/2023)  

[article]  inSOFW JOURNAL > Vol. 149, N° 6 (06/2023) . - p. 12-16 Titre : SPF boosting ? Naturally, natural ! Type de document : texte imprimé Auteurs : Marek Busch, Auteur ; Martina Issleib, Auteur ; Lars Jung, Auteur ; Claudia Teubner, Auteur Année de publication : 2023 Article en page(s) : p. 12-16 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Absorbeurs de rayonnement ultraviolet Dermo-cosmétologie Etude in vitro Etude in vivo Facteur de protection solaire Formulation (Génie chimique) Peau -- Soins et hygiène Produits antisolaires Produits chimiques -- Biodégradation Ressources renouvelables Index. décimale : 668.5 Parfums et cosmétiques Résumé : Consumer wishes change based on a growing consciousness for the environment and people. Also, regulations change and evolve due to current and updated scientific findings. This also affects the range of commonly used UV filters. As an industry, we develop products that address these trends and meet those requirements. Consequently, we must find innovative ways to develop and optimize sunscreen products where SPF boosters play an important role. SPF boosters shall increase the value of SPF and preferably UVA-PF and allow to reach higher sun protection factors with the same amount of UV filters. These products are not considered as UV filters because they, alone, do not significantly contribute to SPF or UVA. But they can help sunscreen formulators to answer the demands for high SPF products while considering a limited choice of UV filters. In the pursuit of developing a SPF booster based on renewable and biodegradable raw materials we have evaluated potential candidates for their efficacy. These were incorporated in sunscreen preparations and compared to a placebo formulation without SPF booster, starting with in-vitro measurements of the UV absorbance based on ISO 24443:2021, followed by evaluation of the impact of the SPF booster concentration. The most promising candidates were further tested on their performance in water-in-oil as well as oil-in-water emulsion systems and with mineral and organic UV filters according to the different in-vivo methods ISO 24444:2019, FDA monograph standard 21CFR201.327 and hybrid diffuse reflectance spectroscopy. To extend the set of data the influence of UVA and UVB absorbance was examined as well as the impact on the sensorial profile when adding a SPF booster to an already existing formulation. Showing outstanding efficacy in in-vitro and in-vivo evaluations of the sunscreen protective properties the wax blend SymEffect™ UV performs in different emulsion systems and works with a variety of UV filter combinations to boost the SPF. Additionally, the balance between UVA and UVB absorbance of the initial sunscreen formulations is kept on the same level when including the wax blend, and the final sensory profile is comparable to the placebo formulations.

Less known is the microbiota role in the protection of skin against sun radiation. While a healthy and balanced skin microbiota helps protect the skin in front of the harmful effects of sun exposure, a microbiota having lost the correct equilibrium generates metabolites which affect the aspect of skin, worsening the photo-induced ageing. The active Photobiome™ protects the microorganisms involved in skin photo-protection, boosting the good metabolites (antioxidants, soothing compounds, etc.) which help our skin defend itself in front of harmful radiation. Made from Punica granatum and Gossypium herbaceum stem cells, it contains a skin photo-protecting cocktail. It is a new active with anti-photo-ageing activity backed by a complete panel of in vitro and in vivo tests.

Natural photoprotective antioxidants from garcinia indica fruit rinds : An approach beyond sunscreen / Pranjali Dhawal in SOFW JOURNAL, Vol. 149, N° 6 (06/2023)  

[article]  inSOFW JOURNAL > Vol. 149, N° 6 (06/2023) . - p. 24-28 Titre : Natural photoprotective antioxidants from garcinia indica fruit rinds : An approach beyond sunscreen Type de document : texte imprimé Auteurs : Pranjali Dhawal, Auteur ; M. Deodhar, Auteur Année de publication : 2023 Article en page(s) : p. 24-28 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antioxydants Cosmétiques Dermo-cosmétologie Extraits de plantes Extraits de plantes:Extraits (pharmacie) Peau -- Soins et hygiène Photoprotection Produits antisolaires Produits naturels Index. décimale : 668.5 Parfums et cosmétiques Résumé : Objective : Recent articles have emphasized that sun protection factors (SPF) and UV-A protection factors (UVAPF) are not sufficient parameters for measuring photoprotection. An approach ‘Beyond Sunscreen’ is currently being explored that involves adding antioxidants and antiaging actives to sunscreens to give holistic protection from UV rays. Herbal extracts containing polyphenols have antioxidative and UV-protective abilities including a class of natural benzophenones. In the current study, ethyl acetate, a green solvent, was employed in the extraction of 62.6% garcinol-enriched fraction from G. indica dried fruits rinds and was explored for non-sunscreen benefits apart from its previously reported SPF and anti-aging applications. Methods : Several in-vitro assays were adopted to decipher the mechanistic activity of TEAE such as protection against the ultraviolet rays and/or hydrogen peroxide-induced toxicity, endogenous restoration of superoxide dismutase (SOD), and glutathione (GSH) antioxidants in the 3T3 mice fibroblasts, and geno-protective ability in pBR322 plasmid DNA. The effect of TEAE on UV-induced melanogenesis in B16F10 melanoma cells was also studied. Results : TEAE revealed cell protective effect against damage caused by different doses of UV-A and UV-B and hydrogen peroxide (H2O2) alone and in combination. TEAE also showed UV-H2O2-induced DNA damage protection activity. TEAE exhibited protection by elevating the endogenous levels of GSH and SOD. TEAE showed melanin reduction that was induced by exposure to UV rays. Conclusion : Garcinol-enriched G. indica dried fruit rinds extract serves as a potentially ideal sun-protective candidate by virtue of its previously reported sunscreen and currently highlighted non-sunscreen benefits.

The skin's microbiome : Establishing a quality seal for cosmetics & consumer expectations / M. Brandt in SOFW JOURNAL, Vol. 149, N° 6 (06/2023)

Langues : Anglais (eng) Catégories : Caractérisation Certification Consommateurs -- Préférences Cosmétiques Justification de l'allégation Labels Microbiome cutané Index. décimale : 668.5 Parfums et cosmétiques Résumé : Quality seals being precisely defined, transparent and validated could help consumers in their decision making. This applies particularly for new categories of cosmetics e.g. those related to the human skin microbiome The knowledge on the human skin’s microbiome grows rapidly and a huge number of cosmetic products with ‘microbiome’ claims are now seen on the global market. Developing a credible and valid quality seal for supporting approved claims on skin microbiome is challenging. Here we propose standards for a quality seal for cosmetic products claiming to be ‘microbiome friendly’. We assume that such a claim can be made if: there is no significant change in microbial diversity as measured by e.g. the Shannon Index and there is also no significant dissimilarity between untreated and treated skin as measured by main component analysis (e.g. Unifrac distances); Also, it should be controlled that there is no strong increase or decrease in the abundance of single microbe genera. Further, evaluation of the skin in terms of clinical safety, skin pH and barrier integrity should also be performed.

Thunig, Auteur ; B. Glassl, Auteur ; K. Kumposcht, Auteur ; S. Morris-Piou, Auteur Année de publication : 2023 Article en page(s) : p. 36-39 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Hygiène Nettoyage Tâches ménagères Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Housework is much more than “just cleaning”. The way cleaning is done allows conclusions to be drawn about social norms, behavioural patterns, the current emotional state and about the state of society. In this context, the Industrieverband Körperpflege- und Waschmittel e. V. (German Cosmetic, Toiletry, Perfumery and Detergent Association, IKW) commissioned a study from INNOFACT AG that examined the topic of housework from a holistic perspective. Note de contenu : - How the topic of cleaning is anchored in people's minds : Lessons learnt – children’s help in the household - Imprinting and motivation - cleaning has an emotional component - Social norms : The understanding of roles changes slowly : Sharing household care : Younger people and East Germans distribute housework more evenly - Cleaning changes over times - Sustainability between relevance and implementation - Digital aids for housework only relevant in certain areas - Digitalisation makes its way to housework - through the back door - Mopping and vacuuming robots - what is used for cleaning ? - Fig. 1 : shows the methodology and the most important data of the study "So putzt Deutschland" ("How Germany cleans"), which was conducted by INNOFACT AG on behalf of IKW - Fig. 2 : Relevance of order and cleanliness in the parental home compared to one’s own household are almost identical - Fig. 3 : Slightly more than half (61%) of the respondents say that their motivation to clean is largely self-driven, while 51 per cent need external factors as motivation for housework - Fig. 4 : The social norms : It was deeply anchored in the parent's generation that the mother looked after the house. 98 per cent of the respondents stated that it was predominantly the mother who took care of the housework - Fig. 5 : In the new federal states, 68 per cent of the housework in the parental home was done by both parents, in 28 per cent of the cases equally. In the old federal states, 45 per cent did the housework together and 15 per cent equally - Fig. 6 : Only 20 per cent of the respondents in the study “So putzt Deutschland” ("How Germany cleans") use a cleaning schedule, which is either strictly or rather loosely adhered to. Of this group, 89 per cent create it in paper form, 11 per cent use an app En ligne : https://drive.google.com/file/d/1xTSks24D6rsRNywYWPEMcuoaeULc_L1T/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=39589 [article]
