Correlating Transepidermal Water Loss and Percutaneous Absorption: An Overview
By: Jackie Levin and H.I. Maibach
The extensive procedure required to measure percutaneous absorption versus transepidermal water loss (TEWL) enhances the desire to find a correlation between the 2 measurements to more easily assess skin barrier function. Experimentation investigating the correlation between TEWL and percutaneous absorption has yielded mixed findings. Yet despite the significant quantitative correlation demonstrated in some experiments, the precise qualitative relationship between percutaneous absorption and TEWL remains unsettled.

Parting Remarks
By: Larry Plonsker, Chemical Network Associates
This column, “Focus on Technology Transfer,” began in the January 2001 issue of Cosmetics & Toiletries magazine. I have had the privilege of writing this quarterly column for five years. In that first issue, I said that the purpose of the column “is to keep the readers of C&T magazine aware of some new and interesting developments that are taking place at research centers around the world.” I hope that you found some leads and were able to develop innovative and interesting products and relationships from the technologies presented in the articles.

Palmitoyl pentapeptide: Robinson et al. report on the topical use of palmitoyl pentapeptide to improve photoaged human facial skin. The palmitoyl pentapeptide palmitoyl-lysine-threoninethreonine-lysine-serine (pal-KTTKS) is a synthetic material that was designed as a topical agent to stimulate collagen production and thus provide a skin antiwrinkle benefit.

Caring for Colored Hair
By: Charles Fox, Independent Consultant
Researchers have studied the moisturizing effects of topical nicotinamide on atopic dry skin. Certain moisturizers can improve skin barrier function in atopic dermatitis. The effect of topical nicotinamide on atopic dry skin is unknown. The effect of topical nicotinamide on atopic dry skin was studied and the results compared with the effect of white petrolatum in a left-right comparison study. This and other studies are described in this Technically Speaking column.

Inside the Hair: An Advanced Hair Biology Model
By: Randy Schueller and Perry Romanowski, Alberto-…
In this survey from the literature, various writers describe a model of the inside of a hair strand, showing a multilamellar structure of the cuticle cells, a multifibril structure of the cortex, and a variety of lipids that are thought to be major contributors to the hair’s physical properties. What exactly is hair? Simply put, the answer is that hair is protein. But this simple answer does not even begin to explain the complexity and sophistication of the hair fiber.

Some New Antimicrobials
By: Charles Fox, Independent Consultant
Those interested in an update on skin moisturization should obtain a reprint of the review “Stratum Corneum Moisturization at the Molecular Level: An update in relation to the dry skin cycle” by Rawlings et al. It traces the development of thought about the mechanism for skin moisturization for the past few decades. Charles Fox covers this any many other topics in his column.
