Repairing Hair with Natural Actives
By: Jean-Christophe Choulot, PhD ALES Group
The present article reviews the structure of hair and various types of hair damage, demonstrating that repair treatments must intervene at several levels within hair. While film-forming agents are often used, they slow or prevent the penetration of actives. A hair serum including natural actives and omitting these film-formers was thus formulated and tested for its repair capabilities.

Sustainability: Trends in Polymers and Surfactants for Hair Care
By: Michael J. Fevola, PhD, Johnson & Johnson; Cam…
Market trends are driving the development of polymer and surfactant ingredients toward natural origins—in particular, plants. In this article, the authors review some of the recent trends in green surfactants and polymers for hair care. One interesting technology transfer trend is the use of hydrogen-bonded supramolecular networks to produce self-healing fixative films.

Ingredient Profile—Guar Hydroxypropyltrimonium Chloride
By: Michael J. Fevola, PhD, Johnson & Johnson
Guar hydroxypropyltrimonium chloride (GHPTC) is one of the most widely used cationic polymers in the personal care industry. GHTPC is employed primarily as a conditioning agent in shampoos and body washes. In many of these rinse-off products, it is also a critical deposition aid for the delivery of active ingredients and hydrophobic conditioning agents, e.g., silicones, to the skin and hair.

Ethyl Lauroyl Arginate HCl for Natural Preservation
By: Maria Minguet, PhD; Rut Barcelona, MD; Eduard …
Ethyl lauroyl arginate HCl (LAE), derived from natural lauric acid and L-arginine, is shown here to provide broad-spectrum activity against microorganisms including Malassezia furfur and Propionibacterium acnes. In vitro tests corroborated by in vivo evaluations suggest its efficacy in anti-dandruff and dermo-purifying applications.

Improving Deposition From High-water Formulas Using Amphiphilic Polymers
By: Mussarat Noor; Richard Goddard, PhD; and Arnol…
Effective high-water skin care systems may play an important role in addressing emerging market consumer needs. The present study considers the challenges of such systems, particularly regarding the deposition of ingredients across water solubilities, and proposes an amphiphilic cationic polymer as one possible solution.

Pollution and Aging: Antioxidants for Skin
By: Jean-Francois Nicolay and Christophe Paillet, …
Cell membrane-derived lipidic hydroperoxides, introduced into the skin by environmental stresses, seem to be key players in oxidative stress-mediated extrinsic aging. Imidazole-containing peptidomimetics can protect against their toxicity through a variety of mechanisms.
