A Dermatological View—Scalp Irritation From Hair Care Chemicals
By: Hongbo Zhai, MD, and Howard I. Maibach, MD, Un…
While scalp irritation also can be caused by contact with physical or biological agents, this column will discuss the irritation resulting from hair chemicals. The desire for a specific hairstyle or color can render the scalp exposed to different hair chemicals that may result to scalp irritation.

Structured Surfactant Systems for Improved Lasting Deposition of Perfume on Skin and Hair
By: Caroline Mabille, PhD, Rhodia Aubervilliers R…
To maximize perfume delivery from structured cleansing formulations, the fragrance must be introduced before structuring the formulation into multilamellar vesicles. Structured formulations fragranced in such a way are shown here to improve perfume deposition and duration versus micellar systems, with no negative impact on perfume burst during use.

Bar Soap Containing Water-soluble Phosphate Polymers for Controlled Release of Antimicrobial Silver and Other Bioactive Metal Ions
By: David M. Healy, Giltech Ltd.
This paper presents data on the antimicrobial performance of a silver ion-releasing phosphate polymer incorporated into a bar soap product. Two studies test the speed, efficacy and longevity of the antimicrobial effect, highlighting the potential of these materials for the controlled, sustained release of bioactive metal ions in cosmetic products.

Formulating for Electrolyte Resistance in Conjunction with Sensory Appeal
By: Marie Ollagnier; Gordon Hsu, PhD; Bryan Moran;…
Skin care formulations often are enriched with high levels of electrolytic ingredients for various skin benefits. However, these have a negative impact on the viscosity, texture and stability of a system. Described in this article is a multifunctional polymer that is designed to provide excellent electrolyte resistance along with a pleasant sensory profile, as will be shown.

A Compound to Increase Natural CoQ10 for Anti-aging Benefits
By: L. Bergeron; K. Cucumel, PhD; Y. Guerif; L. Mu…
Oxidative stress is a major factor in skin aging, thus a topical compound was designed to increase anti-oxidant coenzyme Q10 (CoQ10) within the body. Described here are in vivo and in vitro studies assessing the compound’s antioxidant and anti-aging capabilities. Results indicate that the modulation of intracellular CoQ10 and its binding proteins appears to protect skin from oxidative damage.

Formulating With Naturals—Hair Conditioning
By: Art Georgalas, Georgalas Endeavors
This column proposes that the current natural and organic hair conditioner market can de divided into two types—those that are effective but use technology considered suspect under most natural certifications, i.e., “greenwashed,” and those that are more compliant with natural and organic certification but are found by consumers to have performance gaps

A Dermatological View—Moisturizers: Evidence for Efficacy
By: Nava P. Greenfield, Yale School of Medicine; a…
Despite their widespread use and applications, the scientific literature on moisturizers lacks strong evidence to support dermatological use. This article explores current literature on the efficacy of moisturizers to help the industry understand their mechanisms and role in treatment.

A Hydrophilic Silicone Elastomer for Broader Formulating Flexibility
By: Isabelle Van Reeth and Xinyan R. Bao, Dow Corn…
Silicone elastomers for personal care have evolved from cross-linked silicone polymers in silicone fluid carriers, to materials with broader organic compatibility in organic solvents. Recently, hydrophilic properties have been added, which are shown here to enable the incorporation of high levels of water, polar solvents and actives while maintaining organic compatibility and unique sensory characteristics.

Characterizing and Evaluating the Effectiveness of Volcanic Pumice Exfoliants
By: M Estanqueiro (MD), G Bossolani, MH Amaral (Ph…
Pumice has a recognized application as an abrasive agent to promote exfoliation of the skin. In this study, different particle size fractions of pumice sampled from several geologic occurrences in São Miguel’s island, the Azores archipelago, were used in the preparation of exfoliation formulations. Gels and soap were prepared and characterized, and their efficacy evaluated.
