Editorial: Future of cosmetic chemistry: advanced product assessment and chemometrics-assisted evaluation

Le résumé fourni par la source

The cosmetics industry is a dynamic and rapidly evolving field, deeply rooted in innovation and 12 scientific advancement. In recent years, it has witnessed a significant shift toward sustainability and 13 consumer-focused formulations, reflecting a growing commitment to safety, environmental 14 responsibility, and high-performance products. The first contribution to this Research Topic presents advanced statistical analyses for cosmetic product 29 developments (Ping). The study tackles the challenge of predicting consumer preferences based on 30 early sensory evaluations, addressing the limitations of traditional blind-use tests (BUTs), which are both time-consuming and costly. By introducing an innovative approach using Bayesian bootstrapping, 32 the paper enhances the predictive accuracy of expert-conducted sensory testing. This method 33 significantly improves the alignment between early evaluations and subsequent BUT outcomes, 34 offering a streamlined and efficient framework for the cosmetic product development process. 35The second contribution introduces an innovative approach to objectively assess makeup foundation 36 coverage (Blaksley et al.). Traditional sensory evaluations, often inconsistent, are replaced with 37 hyperspectral imaging to analyze detailed spectral data from facial skin before and after application. 38 Key parameters, homogeneity factor (αHF) and spectral shift factor (βSF), quantify coverage consistency 39 and color changes, respectively. The study demonstrates strong correlations between these metrics and 40 sensory rankings, offering a reproducible, quantitative method to evaluate makeup coverage.
