Beyond the Obvious in Sun Care Formulating

What are the biggest challenges in sun care formulating? I asked a few colleagues, and they answered: achieving what marketing wants while complying with regulations and making sunscreens esthetically pleasing (so consumers will use them); and the lack of international harmonization in UV filters, UVA testing and labeling. These issues are not new, so why are they not yet resolved? Perhaps because regulations and consumer demand are moving targets, which are difficult to hit.

Wise Words From the Bench With L’Oréal's Claudie Willemin

Claudie Willemin sees legislative and regulatory requirements in a more positive light: as an opportunity for innovation. This attitude has built her successful career of more than 20 years in the cosmetics industry, some of which she recounts here.

Film-Formers Enhance Water Resistance and SPF in Sun Care Products

At low formulating levels, film-forming polymers can increase water resistance and enhance SPF in sun care formulations, while also imparting improved aesthetics. In the case of C30-38 olefin/isopropyl maleate/ MA copolymer, a synergistic SPF effect can be achieved with PVP/eicosene copolymer.

Sunscreen Stabilizer for Improved SPF

The photostabilizer quenches the singlet excited states to slow down photodegradation.

The Effects of Solvents on Sunscreens: A New Ester to Improve Efficiency

The present paper evaluates the effects of solvent systems on the in vivo SPFs of sunscreen formulations. Formulations incorporating identical active systems were prepared using traditional solvent systems and varying concentrations of sorbeth 2 hexaoleate, a new ester having both polar and nonpolar segments. Results indicate the ester enhances SPF in a dose-dependent manner.

Antioxidants in Sunscreens for Improved ROS Protection

In the present article, sunscreens containing the antioxidants vitamin E and diethylhexyl syringylidene malonate were tested for their efficacy in preventing UV-induced reactive oxygen species in the lower stratum corneum. The addition of the antioxidants was found to significantly improve the ability of low to high SPF sunscreens to attenuate ROS formation in UV-exposed skin.

Polycrylene for Photostabilization and Water Resistance

HallStar has created a polyester that allows formulators to combine active ingredients that have previously been considered too photo-unstable to be effective.

Transparent, Water-resistant Sun Care Formulations Developed

Ashland Specialty Ingredients has launched water-resistant sun care formulations that are transparent on skin, even in the presence of water.

Sunscreen, Actives Stabilizer

The HallStar Company will showcase recent innovations using its ethylhexyl methoxycrylene photostabilizer, which stabilizes sensitive ingredients and enables sunscreen formulators to meet and exceed international requirements for sun care.
