Thermoplastic Silicone Elastomers Improve Nail Polish Performance
By: A. Schlosser and L. Hassenzahl, Wacker Chemica…
A new thermoplastic silicone elastomer (TPSE) is shown here to improve scratch resistance, chip-off, feel, smoothness, gloss, and color in a nail polish formulation when compared with a formulation without TPSE. The new ingredient proves to be an interesting technology for optimizing nail polishes.

Properties of Surfactants: Wetting
By: Anthony J. O'Lenick, Jr., Siltech LLC
In formulation, the key attributes of surfactants are conditioning, wetting, emulsification, and detergency. This article describes the features of surfactants that provide wetting properties in aqueous systems. Specifically, the properties of interest include surface tension reduction, HLB, molecular weight, branching, and level of ethoxylation. The choice of the best wetting agent depends upon chemical structure and the formulation.

A Laboratory Method for Measuring the Water Resistance of Sunscreens
By: Berislav Markovic, Donna Laura and Mark Rerek,…
A new laboratory in vitro method for the measurement of sunscreen water resistance uses spectrophotometric analysis of a model skin substitute before and after 80-minute immersion. It gives good correlation with the FDA’s 80-minute immersion SPF results (very water resistant). The method is especially good for screening new formulations or water-resistant technologies.
