In vitro SPF measurements are challenged by reproducibility, repeatability and correlation with in vivo values. Here, the authors assess sunscreen adhesion to the test substrate support, since poor adhesion produces bad results. Surface substrates are characterized by functional group, charge, wettability and surface morphology. Eight w/o and o/w emulsions also are tested. Results indicate an ideal in vitro test substrate does not exist.

Ranking descriptive analysis (RDA) is a sensory test from the foods industry. Here, it is applied to evaluate the properties of four body creams, and the results are compared with those of the well-known quantitative descriptive analysis (QDA) profiling. Findings suggest this technique could positively impact sensory testing for product development.
