Titanium Dioxide Particle vs. Sun Protection Performance

The article compares the performance of titanium dioxide as a UV filter in cosmetic formulations as a function of its primary particle size. It was found that with increasing primary particle size, even below 100 nm, the effectiveness of the inorganic (mineral) UV filter was clearly reduced.

In Sight: Stopping the Sun

With global warming ever-increasing the penetration of the sun, the emergence of sun care innovation is not only beneficial but vital. Many have high hopes for ecamsule, but as of now, it scope remains limited.

Hippo Sweat Found to Have UV Protection and Antibacterial Activities

If suppliers and manufacturers are not already working on synthesizing hipposudoric acid for skin and sun care, perhaps this "river horse" research could inspire future research.

Sun Protection Conference Addresses the Future of Sun Care

The conference opened the summer season for sun care scientists, and the topics included SPF and UVA standard tests, new sunscreen actives, greater product efficacy and improved product textures.

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.

The Quest for Avobenzone Stabilizers and Sunscreen Photostability

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.

Deciphering Sun Damage Prevention and Repair Formulas

It is obvious that UVA and UVB radiation damage human skin. Therefore, the question of whether UV damaged skin can be adequately repaired remains to be answered.

AACR Study Suggests Sunscreen Message Still Needs Work

Although, more people are using sunscreen now than in past years, the industry still has a ways to go, according to a study conducted by the American Association for Cancer Research (AACR). The study found that not only do only 17.2% of Americans use sunscreen on a regular basis, but only 32% of melanoma survivors wear sunscreen regularly.

Developing Sunscreens for the Preventive Treatment of Photodamage and Premature Aging

This article reviews the mechanisms of ultraviolet radiation insult to skin and explains the formulation of sunscreens to protect against this damage. Further, since the efficacy of combinations of UV filters will vary with formulation base, the formula vehicle and form are discussed, as well as an overview given of typical sunscreen efficacy tests performed prior to production.

Sun Care Use: Beach Survey

In September 2012, 101 sun care product users were surveyed on the beach regarding what SPF and product form(s) they were using, among other questions. While 12.2% used SPFs of 15–29, a 58% majority used SPFs of 30–50. Lotions were the favored form, followed by sprays. This article reports the detailed findings from this survey.
