Advances in Hair Styling
By: Raymond Rigoletto; Anand Mahadeshwar, PhD; Lin…
All hair styling formulations start with a framework that is adjusted to obtain the correct viscosity, flow, etc. Auxiliary ingredients are then added to fine-tune the formula with respect to aesthetics, benefits and compliance. This excerpt from the May 2012 issue of Cosmetics & Toiletries presents a review of the components in hair styling products.

Hair Color Vibrance Factor to Characterize Shine and Color Intensity*
By: Timothy Gao, PhD; Peter Landa; Regan Tillou; a…
To evaluate the comprehensive effects of shine and color intensity in hair, a hair color vibrance factor has been developed to enable new claims for hair dye formulas and after-dye treatments. Experimental results described here show how varying the ingredients in shine spray and hair dye formulas affect this factor and correlate with subjective panelist assessments.

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.

Ingredient Profile—Benzoic Acid/Sodium Benzoate
By: Michael J. Fevola, PhD, Johnson & Johnson
Benzoic acid (BA) is a leading choice due to its long and successful history of use preserving foods, drugs and cosmetics. Affirmed as GRAS (Generally Recognized As Safe) by the US Food & Drug Administration (FDA), BA and its sodium salt, sodium benzoate (NaB), are perhaps the most globally acceptable preservatives that have managed to avoid the controversy associated with many of the industry’s tried-and-true preservatives.
