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.

Formulating Antiperspirants and Deodorants With Naturals

Within the realm of natural and organic personal care products, deodorants and antiperspirants loom large simply because the overall category itself is very large in any retail health and beauty aids planogram. These two related products—i.e., antiperspirants and deodorants (AP/Deo)—are fraternal twins joined at the axilla that perform in this same anatomical arena using some of the same tricks.

Great Un-expectations

Taking unexpected turns leads us down new paths of discovery, which is especially relevant to science and certainly applicable to personal care product development.

Read the Label: L’Oréal Go 360˚ Clean Deep Facial Cleanser

Rather than adding abrasives directly to the formulation, a removable “scrubber” was attached to the bottle of this product for the consumer to apply the cleanser. It is a clever take on an otherwise uninteresting formula.

Formulating Ferulic Acid for Antioxidation

Joseph Laszlo, PhD, lead scientist for the US Department of Agriculture’s (USDA) Biocatalytic Functionalization of Plant Lipids project, and his team have developed a process through which vegetable oil, in this case soybean oil, can be given antioxidant and UVA/UVB protective capabilities.

Red Pump Solutions

First, if you haven’t noticed, Suppliers’ Day is themed “Project Trendway: Your Stage for Innovation.” This is appropriate considering the industry celebrities, press and scrutinizing eyes of would-be buyers that will be watching as exhibitors strut their latest and greatest on the Suppliers’ Day catwalk.

Nonaqueous Emulsions: History and Current Specialized Applications

Since the early 1980s, nonaqueous emulsions have attracted technical interest as potential vehicles and delivery systems for personal care products. This is due to the development of a broad range of silicone-based emulsifiers, silicone polymers and other polymeric emulsifiers that have enabled their use. This article will briefly review their history and evolution into current-day specialized applications.

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.

Formula Anatomy Deciphered—Hand Creams and Sanitizers

Hands also frequently provide symbols and perceptions of human personality, energy and mood, and because these multitasking tools are easily soiled, they must be frequently cleansed.

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.

Formulating Sunless Tanning Products with DHA: Current Challenges

Dihydroxyacetone (DHA) remains the most effective ingredient for sunless tanning; however, it poses several challenges to the formulator. Following is a review of those challenges, including: stability, malodor during the browning reaction, compatibility issues with sun protection ingredients and the generation of free radical damage. In addition, the author suggests some solutions to these challenges.
