Influence of Pressure During Spreading on UV Transmission Results
This work evaluates the impact of applied pressure during sample spreading on the in vitro measurement of UV transmission. The authors work in a range of pressures between 50–200 g and demonstrate that pressure control is a key parameter that should be strictly controlled to ensure the reliability of test results.

UV Transmission Assessment: Influence of Temperature on Substrate Surface
This work evaluates the impact of temperature on test substrate surfaces during the application, spreading and drying steps of the in vitro method to measure ultraviolet (UV) transmission. The authors work in a range of temperatures, between 20°C to 35°C, and demonstrate that controlling temperature is a key parameter and should be strictly controlled to ensure reliability.

Comparatively Speaking: The INCI Names vs. Properties of Silicone Surfactants
Surface tension is a ruling factor in the formulator's world. In this edition of "Comparatively Speaking," Tony O'Lenick explains its influence on foam and wetting; he also demonstrates how little the INCI name reveals about a material's properties.

DNA Metabarcoding Tracks Traceability of Naturals: Wild Teasel Case Study
This study authenticates
D. fullonum
from raw material to final ingredient. It compares
D. fullonum
and
D. sylvestris
in a three-step study by: barcoding the raw material, metabarcoding the two extracts and bioinformatics processing.

Sandblasting to Improve the Reproducibility of In vitro Sunscreen Evaluation
SPF test results from substrates treated using a traditional sandblasting technique are compared with those from substrates treated using a new process. Based on the topographic control of 10 batches and 34 sunscreen evaluations, the authors concluded the new process had better topographic reproducibility, consequently improving the SPF repeatability and reproducibility in vitro.
