Advances in Polymers for Hair Conditioning Shampoos
By: Robert Y. Lochhead and Lisa R. Huisinga, Schoo…
The dilution-deposition mechanism is the core of the modern conditioning shampoo. It is described here, along with polymer inventions that enhance benefits and improve the clarity of conditioning shampoos, and enable conditioning from shampoos that do not contain a cationic polymer.

Advances in Polymers for Hair Styling
By: Robert Y. Lochhead and Lisa R. Huisinga, Schoo…
Block and graft copolymers, including some produced by living free-radical polymerization, are among the new hair fixative polymers surveyed in this article. Other new polymers offer advantages in hair styling gels, hair straightening and hair conditioning.

Stimulation of Dermal and Epidermal Metabolism: An Approach to Antiaging
By: Maud Jouandeaud-Le Guillou, Sylvie Bordes, Cat…
Aging results in a number of modifications to cells and tissues. Here the authors describe an active ingredient from common mallow whose active fraction containing polyphenols and galacturonic acids is able to regulate both dermal and epidermal metabolism much like retinoids do.

Examining an Exfoliation-Promoting Enzyme for Cosmetic Applications
By: Toshihiko Seki, Shiseido Co, Ltd.; Isao Yajima…
To investigate the biological function of proteases on desquamation and their possible cosmetic applications, the authors evaluate the effects of degrading and exfoliating on human SC sheets of chemical cross-linking subtilisin (CL-SB), a highmolecular-weight enzyme derived from serine protease of Bacillus licheniformis

Delivery Review—Looking at Liposomes
By: Johann W. Wiechers, PhD, Uniqema
In this short review, the author outlines cosmetic delivery systems of the past and present and gives predictions for delivery systems of the future. From transdermal drug delivery principles of the past to the latest trend in elastosomes, good scientific evidence is vital if the industry really wants to deliver benefits to its customer.

Pathways for Skin Penetration
By: Nava Dayan, Lipo Chemicals Inc.
This paper reviews recent findings about three skin penetration pathways (including a “polar pathway”) and four types of penetration enhancers (enzymes, vesicular systems, ceramides and chemical enhancers).

Neonatal Skin: Structure and Function
By: Edward K. Boisits, PhD, International Research…
Within the embryonic/fetal development program, skin is of major importance. Much of the activity in skin development is centered around formation of the epidermis, which ultimately generates the stratum corneum. The present article touches the surface of the structure and function of neonatal skin.

Busy Signals Explain Itch from Dry Skin
By: Gil Yosipovitch, MD, and Kelly L. Barham, MD
This review of literature suggests that crosstalk between the stratum corneum and nerve fibers in the epidermis is the process by which itch is transmitted to the central nervous system. A rationale is presented for using moisturizers to reduce itch.

Formulators Forum - Sunscreens: Current Issues and Controversies
By: Ken Klein
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?
