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.

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.

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.

Read the Label: Bella B Sunny Bee Natural Sunscreen 40+ SPF

This is a liquid crystal emulsion based on C14-22 alcohols and C12-20 alkyl glucoside. Glyceryl stearate is used to reinforce the lamellar network. Beeswax, which should only be listed once, is used as a natural oil phase thickener.

Envisioning SPF

The sun care industry faces several challenges, including testing and measuring SPF, questions over the safety of nanotechnology, sunscreen stability, broad-spectrum protection, and inconsistent regulations for allowed UV filters and their combinations. Some of these challenges have plagued product developers for years, thus the industry has had time to develop the means to meet some of them. Recent work in these areas is the primary focus of this issue of C&T magazine.

Controlling Hydroxyl Radical Formulation in TiO2 Sunscreens

Titanium dioxide (TiO2) is an effective sunscreen agent but its rutile form may produce hydroxyl radicals upon exposure to sunlight. Thus, the authors use salicylic acid as a capture agent to examine the development of free radicals in solutions or creams containing TiO2. They also explain how the choice of emulsion may reduce free radical generation.

BASF Launches a UV Filter, Anti-aging Formulation Concepts, BB Cream Pigments an Under-eye Sea Extract and More

At in-cosmetics 2013, BASF Personal Care will introduce a new UV filter, a multifunctional styling agent, a renewable microemulsion, natural platelets for mineral makeup, a sea extract for under-eye and formulation concepts for anti-aging and diverse daily activities.

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.

Wise Words From the Bench with Gavin Greenoak

After 25 years in the industry, Gavin Greenoak, managing and scientific director of the Australian Photobiology Testing Facility Pty., Ltd. (APTF), continues to strive for a better understanding of the interaction of light and the human body. Greenoak’s career began in cancer research, which has afforded him unique insight of skin biology and the effects of sun exposure.

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.
