Botanical ingredients are interesting for their unique and complementary chemical diversities yet they are criticized for these very traits, which make quality assurance, reproducibility and good phytochemical characterization—required for successful high throughput screening, difficult. This article discusses these challenges as well as the benefits of large-scale screenings of botanical extracts that are currently used or developed for cosmetic product development.

Functional filler pigments play an important role in adjusting optical properties such as transparency and soft focus effects in cosmetics. However, their suitability for specific formulas is not apparent until time-consuming tests using many different fillers have been conducted. Therefore, a new method to predetermine the soft focus effects of functional filler pigments is described here.

The present article describes a reproducible method for determining the photostability of sunscreen products. This method is based in part on the in vitro determination of the UVA protection factor as proposed by Colipa for the irradiation aspect, and on the spectroscopy of a sunscreen in dilute solution for the absorbance measurement aspect.

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.
