A sunscreen layer’s thickness is critical to its SPF. However, current regulations specify a mass application rate for testing, rather than a volumetric application rate. This significantly underrates the SPF values of mineral sunscreens due to their higher densities since, compared with their relative organic counterparts, thinner films are being tested, as will be shown here.

This study assesses the physicochemical properties of four known cosmetic emollient esters in vitro to predict their sensorial benefits and correlate their properties with in vivo sensory attributes. This evaluation serves as a guide to selecting specific emollient esters for various cosmetic applications and to predicting their sensory attributes.

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.
