DOWNLOAD EBOOKIn the early 20th century, tanned skin was associated with good health. However, people began to protect themselves against potential overexposure to avoid sunburns. Around 1945, the first sunscreen products became available. In the years to follow, a vast number of different sunscreen filters and frameworks regulating filter substances and preparations, and methods characterizing sunscreen products were developed. The perception regarding the tasks of sunscreen products changed several times - initially it was promoted as a lifestyle product, then as a skin cancer preventive means, and more recently also for anti-aging. Different purposes and the widespread use of these products have led to myriad studies and a wealth of information. In this volume, the editors present a current collection of information analyzing and discussing issues related to sunscreen products and their use. These include challenges regarding the ideal sunscreen product including filter selection and formulation issues, measurement methods, performance characterization, safety, and regulatory issues. Further papers address topics related to the use of sunscreen products in everyday life, in vulnerable cohorts and outdoor workers. Controversial topics such as environmental effects of sunscreen products and the risks and benefits of UV radiation in the context of skin cancer, vitamin D and cardiovascular and metabolic health are also covered.
Evaluating UVB and UVA Boosting Technologies for Chemical and Physical Sunscreens

DOWNLOAD EBOOKThere are currently 14 organic and 2 inorganic UV filters approved in the United States. Due to coral reef safety concerns, octinoxate and oxybenzone have been banned in Hawaii, Key West, FL and the US Virgin Islands; and octocrylene is also being studied for its potential impact on coral reef safety, leaving 11 organic UV filters as viable options for sunscreen manufacturers - with limitations on their combination. Since consumers are always looking for sunscreens with high SPF and broad-spectrum protection, the need for UVB and UVA protection boosting technologies is greater than ever. In a preliminary study, about two dozen emollients were scanned for their SPF boosting capability with selected organic UV filters. In this study, our goal was to evaluate whether and to what extent the in vitro SPF and broad-spectrum protection of three selected organic UV filters (homosalate, octisalate and avobenzone) and the two inorganic UV filters (zinc oxide and titanium dioxide) can be boosted with three selected emollients (diethylhexyl 2,6-naphthalate, C12-15 alkyl benzoate, and butyloctyl salicylate), and an SPF boosting ingredient (SunSpheresTM). Organic, inorganic and mixed organic/inorganic sunscreens were formulated and tested for stability, viscosity, spreadability (TA.XTPlus texture analyzer), and droplet size; as well as in vitro SPF and broad-spectrum protection (LabSphere 2000S), and water resistance. The results show that C12-15 alkyl benzoate provided the highest in vitro SPF out of three emollients tested for the organic sunscreens. However, this ingredient did not form a stable emulsion with our inorganic ingredients, therefore, butyloctyl salicylate was selected to be used for this research project. Titanium dioxide had a higher in vitro SPF value; however, zinc oxide provided broader spectrum protection. Therefore, zinc oxide was selected to be combined with the organic UV filters. We observed an in vitro SPF increase in the case of all sunscreens after exposing the sunscreens to a 20-minute water bath. We believe that the film-former, i.e., polyamide-8 and the drying time contributed to higher SPF values after the water bath. All sunscreens had a shear-thinning behavior, which is typical for creams and lotions. Overall, the organic/inorganic UV filter-based sunscreen containing the SunSpheresTM (CS) performed the best in terms of in vitro SPF, water-resistance, and spreadability.

DOWNLOAD EBOOKThis book provides a comprehensive and authoritative review of the chemical analysis of UV filters in coastal waters and their impact on the marine environment. The sun care is today the most important sector within the cosmetics industry, with annual increases in sales. The main components of sunscreens, organic and inorganic UV filters, have been detected in many coastal regions, with the highest concentrations in coastal areas under high anthropogenic pressure. Moreover, these compounds have been found to be bioaccumulated in aquatic biota causing biological and toxicological responses; some organic UV filters act as endocrine disruptors in aquatic biota, affecting survival, behavior, growth, development and reproduction. On the other hand, inorganic UV filters, mainly based on nanoparticles, have been demonstrated to have various impacts on marine organisms, such as inducing oxidative stress in abalones, accumulating in microalgae, affecting the immune response in mussels, bleaching corals, and genotoxicity in fish, among others. All these effects of sunscreens on the marine environment highlight the need for more stringent and environmentally friendly regulations. This book covers the latest analytical methodologies used in assessing the impact of UV filters impact on marine waters, especially on marine biota, and also critiques the global regulation of UV filters and the environmental risk of using sunscreens. Featuring specific case studies of the environmental effects of sunscreens in the Mediterranean Sea and Hawaii, which highlight the importance of balancing human health with environmental health of coastal ecosystems, it will appeal not only to scientists and students from various disciplines (environmental chemistry, biology, ecology, biogeochemistry, fisheries and climate change among others), but also to environmental managers wanting to promote new restrictive regulations on the use of UV filters, and to professionals from the cosmetic industry interested in the development of eco-friendly sunscreens.
