Photostability Leads the Way: Formulating Safer Sunscreens
The need to prevent skin from UV damage is well-understood but the most effective way to achieve this is not. Here, a novel photostabilizer is presented in a test pump sunscreen spray formula as part of a total photoprotection strategy.
Safety/Stability
Standardizing Safety: ISO Validation and Sun Protection Tests
In addition, methods under review pertaining to sun protection are discussed. The ISO sets proposed standards and test methods for nearly every industry; its validation process is described here.

World Sunscreen Harmony, Reaching the Consumer and More at the FLSCC's Sunscreen Symposium
There will always be room for improvement in the sun care industry, which continues to innovate worldwide with better UV filters, measurement techniques and finished formulations. This was reflected at the Florida chapter of the Society of Cosmetic Chemists' 2013 Sunscreen Symposium, which was held Sept. 18-21, 2013, in sunny Orlando, Florida.
Claims/Labeling
Sunscreen Claims: Demystified?
As you know, sunscreen products are regulated by the U.S. Food and Drug Administration (FDA) as drugs because they are “intended” to prevent disease (skin cancer). As such, they are required to follow the rules and regulations as mandated by the FDA. Thus, they must use Drug Facts labeling; list the drugs (sunscreen actives) using the proper drug nomenclature; list the percentage of drug used; specify the drug function (sunscreen) and label; warnings and directions for use, etc.
Literature/Data
Patent Picks—Reactivating Sunscreens; Etched UV Protection; Jaboticaba/Cashew Skin Care; Water-soluble Sunscreens
Patent Picks are taken from publicly available sources and cover recent patents issued or applied for in the cosmetic and personal care industries and relevant peripheral markets. This edition features sun protection and skin repair technologies.
Literature/Data
Sunscreen Across the Spectrum?
Newer to the scene are products that protect skin against infrared radiation, as well as research on the effects of high energy visible and visible light. In response, at the
C&T Summit
, Jürgen Lademann, PhD, will present "Should Sunscreens Protect Across the Whole Solar Spectrum?"

Sunscreens: A Closer Look
Differences of opinion pervade the sun care industry—from how to measure UVA/UVB protection, to educating consumers on proper use of sun protection products. Several debates are raging (see Global Sun Care Debates). To serve the spirit of harmonization in our industry and to better define this expanding market, C&T magazine takes a closer look this month at differences of opinion on the definition of the term sunscreen.

‘Very’ Water-resistant Sunscreens
Water-resistance is a key parameter for today’s sunscreens, and there are a number of formulation strategies that can be used alone or in combination to achieve this effect, including: anhydrous formulation, w/o emulsions, film-forming polymers, dissolution of water-insoluble substances with alcohol, low levels of emulsifiers, and entrapping filters in liposomes. These are detailed here.

Unexpected Paths to Sunscreens
Teleportation was once science fiction. Today's it's somewhat of a reality, if you consider how
Facebook Live, Facetime, Skype,
etc., transport our
likenesses
through time and space. I sense this indirect path may be the future to sunscreens.
Preservation
Preservation of Sunscreen Products
Sunscreen products, even those formulated as anhydrous or powder formulations, may need preservative systems because of the high risk of microbial contamination or water intrusion, especially during consumer use around water.
Literature/Data
Sunscreens and Other Products
Modulation of zinc levels and tissue properties: Essentia Biosystems discloses the modulation of zinc levels to improve tissue properties. Methods of altering the properties of tissues were explored by modifying the amount of zinc, which may be in the form of zinc ions, through the use of topical compositions containing one or more zinc-containing components such as salts and/or other zinc compounds or in complexes, particularly zinc acetate. By altering the zinc levels, researchers found they were able to increase or decrease fatty tissue, increase or decrease epidermal thickness, increase elastin content, and prevent or treat gum regression or atrophy.

Sunscreen Formulation and Testing
The author reviews SPF testing methods and sunscreen components (actives, active solvents, water-resistance agents and emulsifiers) that assist the formulator in the art and science of sunscreen formulation.

Research Pathways to Photostable Sunscreens
This article provides a visual depiction of pathways that UV filters undergo when exposed to solar radiation; such pathways often lead to photo-instability. A fluorescence technique is described that has led the author to identify compounds that preserve photostability in a novel manner— by quenching the UV filter’s singlet excited state.
