Structured Surfactant Systems for Deposition of Perfume on Skin and Hair
By: Caroline Mabille, PhD, Rhodia Aubervilliers Re…
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.

A High Throughput Method to Predict Skin Penetration and Screen Topical Formulations
By: Konstantin Tsinman, PhD, Pion Inc.; Bálint Sin…
This work studies the applicability of a 96-well-based skin-mimetic artificial membrane permeability model to differentiate between topical pharmaceutical and cosmetic formulations. Results are compared with data obtained from in vitro Franz cell permeability measurements and reveal the applicability of this method to assess cosmetic formulation permeation and speed the discovery process.

A Dermatological View—Innovations in Hyaluronic Acid
By: Howard I. Maibach, MD, University of Californi…
HA is critically important to dermatologists and to cosmetic scientists, as it maintains the moisture in skin, and loss of accessible HA results in wrinkling and changes associated with aging. Replacement of such HA is the goal of many cosmetic and cosmeceutical techniques and reagents.

Penetration of Cosmetics Into and Through the Stratum Corneum
By: Ada Polla, Alchimie Forever
The penetration routes of substances through the stratum corneum and how these transport pathways function are becoming better understood. Despite this progress, however, the penetration mechanisms of cosmetic formulations remain mysterious. This overview presents current knowledge on the various pathways of penetration, and suggests that even if cosmetic formulations penetrate no deeper than the surface, their efficacy may still be optimal.

Development of a Novel, Soothing Tissue Incorporating Phase-change Materials
By: Jeffery R. Seidling; Scott W. Wenzel; Corey C…
Frequent and repetitive tissue use can lead to inflammation of the nasal area. While technologies were already marketed to help minimize and prevent further irritation, none had targeted the heat and redness associated with an already inflamed nose. This presented a market need but several formulating challenges. Described here are the steps taken to find a practical solution to these challenges.

Formula Anatomy Deciphered—BB Creams
By: Luigi Rigano, PhD, Studio Rigano Industrial Co…
BB stands for “blemish balm” in Asia or “beauty balm” in some parts of Europe. It is defined loosely as a product that combines serum, moisturizer, base cream, foundation and sunscreen in one.

Consumer Perception of Fine Lines and Wrinkles Assessed by Qualitative Methods
By: Rosanna Mootoo, Stephanie Basile, Cristina St…
There are varying definitions, associations and overall impressions of fine lines and wrinkles among different consumer segments. The findings of this study offer invaluable insight into consumers’ opinions, and by qualitative in-depth interviews, they provide a well-defined vernacular for aging descriptors. This language is critical for developmental research, consumer evaluation and marketing within the cosmetic industry.

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.
