Assessing the Impact of Hair Damage Types on Color Retention
By: Denis Bendejacq, PhD, Solvay
This article reviews and assesses damage types caused to hair before and after artificial coloration, i.e., by bleaching, perming, heat treatment, UV exposure and shampooing, to compare how they impact color durability individually and combined. Formulation emerges as the key to designing shampoos that efficiently deliver actives to improve color protection against these and other damage types.

Water Content, Nanoparticles and Skin Penetration in Brazil: Lindo Maravilhoso!
By: Rachel Grabenhofer, Cosmetics & Toiletries…
Water content, surfactants, thickeners, actives, nanoparticles and skin penetration were among the hot topics presented at the biennial XXI COLAMIQC congress of the Latin American and Iberian cosmetic chemists. Held May 14-16, 2013, in São Paulo, technical sessions were paired alongside the FCE Cosmetique exhibition and trade show for both the cosmetics and pharmaceuticals industries.

Mature and Immature Corneocyte Detection Force Distance Curves vs. Microfluorometry
By: Anthony J. Ribaudo, Textile Research Institute…
Here, the author compares two methods to determine the maturity of corneocytes based on their cross-linking that could be used to evaluate the anti-aging effects of molecular agents. The first utilizes microfluorometry, while the second involves F-D curves generated via contact mode AFM. Both methods successfully detected differences in mature or immature corneocytes with 95% confidence.

Testing Tactics—Consumer vs. Scientific Language: Relating In vivo to In vitro
By: Trefor Evans, PhD, TA Evans LLC
It should perhaps go without saying that consumer products are sold using consumer language. Market researchers and consumer scientists spend a great deal of time studying their target audience and learning this vocabulary, which subsequently allows the recounting of product benefits in the same terminology.

Hair Ethnicity and Ellipticity: A Preliminary Study
By: Ali N. Syed, PhD; Tomas N. Ventura Jr.; and Ma…
Ethnic hair care addresses diverse fiber compositions that require unique products. This comprehensive review in hair fiber dimensions among straight, wavy and curly/coily hair serves as a basis from which product developers can design products to cater to unique hair type needs. The current study examines the ellipticity of Caucasian, Brazilian, Hispanic and African-American hair.

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.
