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.

Characterizing the Anti-aging Effects of Hesperomeles heterophylla Hook Leaf Extract
By: Tania Milena Cortázar, Mauricio Guzmán Alonso …
Hesperomeles heterophylla Hook leaf extract was evaluated as described here for its application in anti-aging skin care. This traditional extract exhibited antioxidant and protective properties on the extracellular matrix due to high levels of polyphenols and flavonoids. Further, a formulation containing 0.35% extract was tested in vivo and showed promising effects on wrinkles and skin elasticity.

PEG-2 Caprylylamine: A New Adjuvant Surfactant to Boost Lather Rate
By: Shou Ooshida, Kawaken Fine Chemical Co., Ltd.
PEG-2 caprylylamine, when used as an adjuvant surfactant formulated in a basic cleanser, can significantly increase lathering rate, as sensory evaluations, dynamic and static surface tension measurements, and the Ross-Miles method show here. Mechanisms of action for this new field of research also are discussed.

Formula Troubleshooting: DHA-based Self-tan Products
By: Peter Tsolis,The Estée Lauder Companies; and …
The self-tanning market has been steadily growing due to advances in formulation technology as well as the consumer trend to seek out safer tanning solutions. Ongoing concerns surrounding the harmful effects of the sun’s ultraviolet (UV) rays, along with endorsements from anti-cancer societies, have created the perfect environment for self-tanning products.

Sustainable Ingredient Science: Brown Algae
By: Giorgio Dell'Acqua, PhD, Freedom Actives Corp.
Sea-harvested brown algae is known to have skin benefits and previously has been associated with an increase in skin elasticity. Fucoidan, found in brown macroalgae such as Undaria pinnatifida, is a unique marine ingredient. It is a sulfated, fucose-rich polymer that in nature, protects the seaweed against a range of external stresses, including UV radiation and environmental contaminants such as marine-borne pathogens and viruses.

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.

Water-soluble Phosphate Polymers in Bar Soap for Controlled Release of Antimicrobial Silver
By: David M. Healy, Giltech Ltd., Ayr, U.K.
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.

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.

Influence of Skin Diffuse Reflectance on Sun Damage and Ingredient Efficacy Measurements
By: Olga V. Dueva-Koganov, PhD, Artyom Duev and St…
Current in vitro methods to assess photostability and antioxidant activity do not account for the diffuse reflectance of skin. Described here is an in vitro test that addresses this variable, mimics end-use product conditions and models photodamage processes. The approach is employed to determine the efficacy of an antioxidant from the Camellia sinensis (tea) plant.

T-shaped Siloxane Microemulsion for Improved Hair Conditioning and Protection
By: C. Hartung, PhD; U. Kortemeier; U. Westerholt;…
Described here is a T-shaped cationic siloxane incorporated in a microemulsion to provide a high silicone character material with balanced solubility and high hair substantivity. Wet and dry combability and hair feel were evaluated by panelists, while combing force measurements and differential scanning calorimetry measured conditioning and heat protection, respectively. Color washfastness also was tested using a spectrophotometer.
