Microfine zinc oxide and coated titanium dioxide have been shown to provide excellent broad-spectrum UV protection for the skin. The author describes how the small size prevents the scattering of visible light and prevents undesirable whitening effect on the skin.

While zinc oxide had been used for decades in sunscreen products — remember the white coating on lifeguards’ noses? — it was only approved for this use by the FDA approximately 10 years ago. Prior to that, it was actually considered to be (and still is) an approved skin protectant material.

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.

Design considerations for broad-spectrum UV filters include photostability, solubility, efficacy, safety, registration, patent freedom, and PPD performance. These criteria are described and then applied in the case of bis-Ethylhexyloxyphenol methoxyphenyltriazine (BEMT), a new broadspectrum sunscreen active.

As you know, sunscreen products are regulated by the U.S. Food and Drug Administration (FDA) as drugs because they are “intended” to prevent disease (skin cancer). As such, they are required to follow the rules and regulations as mandated by the FDA. Thus, they must use Drug Facts labeling; list the drugs (sunscreen actives) using the proper drug nomenclature; list the percentage of drug used; specify the drug function (sunscreen) and label; warnings and directions for use, etc.

Like you, I have attended an astounding number of scientific conferences and have read seemingly unending technical papers dealing with what most of the time are topics of interest to cosmetic chemists. While we always can learn from these meetings and articles, it seems to me that there is a real lack of technical controversy. We sit and quietly accept what is heard as gospel. While we may not agree, we nevertheless just sit back and don’t ask the hard questions. Does this make sense? Was the test design reasonable? Did they use the proper controls?
