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.

When formulating a hair care product, there is often a need for testing that validates the product’s technical performance. This testing provides guidance to create formulas with appropriate performance, while also communicating the product’s message to the consumer. This article discusses the use of instrumental combing measurements when formulating hair conditioning products.

Fluorescence Laser Scanning Confocal Microscopy to Assess the Penetration of Low Molecular Protein Hydrolyzates Into Hair
By: Olga Freis and Dominique Gauché, Laboratoires …
The present study uses confocal laser scanning fluorescence microscopy to assess the penetration of protein hydrolyzates into hair. While higher amounts of protein were found in the cuticle, still significant quantities were observed in the cortical parts of hair, and this penetration was enhanced by longer incubation times.
