A new water-in-oil-in-water technology is described here that functions as an isolating shield, preventing UV filter particles from aggregating and helping their dispersion in formulas. The technology is shown in vitro and in vivo to improve SPF performance, UVA/UVB wide band high protection ratio, SPF sustainability and safety concerns regarding skin penetration.

Inorganic UV filters must be distributed evenly to ensure sun protection. Further, they can present challenges of a pasty consistency and undesirable opacity when applied to skin. This paper therefore describes strategies using micronized titanium dioxide with different coatings to optimize its dispersion and protective benefits while improving processing and aesthetics.

During in-cosmetics in Hamburg, Symrise launched SymTio S, a cetearyl nonanoate-coated titanium dioxide for sunscreens, to improve the feel of sun care formulas and reduce the potential for white film forming on the skin.

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.

This article discusses formulating strategies to achieve high-SPF sunscreen formulations that are cosmetically elegant and also cost-effective. By carefully choosing actives that complement one another in terms of spectral coverage, and physical and chemical properties, synergistic combinations of relatively inexpensive UV filters can be identified to deliver effective and elegant formulations.

This article examines the ability of liposomes to improve the in vitro skin penetration of Hevea brasiliensis extract in a cream, for antioxidant benefits. Additionally, the sensory effects of the liposomes on the cream were assessed.

Sunscreen sprays have gained momentum due to their ease of application. However, while they appear clear on dry skin, they often turn cloudy and white when applied to wet skin. Here, the authors present a formulating approach based on the dielectric constant of esters and level of alcohol in formulations to produce anhydrous sprays that appear clear on wet skin.

Butyl methoxydibenzoyl methane (BMDBM) is well-known as an effective UVA filter when it is stabilized. Here, the authors measure the efficiency of ten commercially available products that are reported to stabilize BMDBM. The most effective product found was octocrylene that, being a UVB filter, also contributed to the SPF.

Dolichos biflorus cell culture extract is evaluated here for its effects on skin cells. Results indicate the extract provides strong anti-inflammatory, antioxidant and protective properties for skin, and the ability to repair UV-induced damage. Further, this work reinforces that cell culture systems are efficient biofactories to produce natural and effective compounds.
