Advanced Characterization of Soft Cosmetic Film Deposits with X-Ray Microtomography.

ABSTRACT: Cosmetic materials are complex soft compounds, including pigments, emulsifiers, film-formers, and fillers. After evaporation or absorption, they form a residue of inert ingredients called the cosmetic film. This thin layer, deposited on the skin, enhances complexion by smoothing texture, concealing imperfections, and evening skin tone. However, visualizing and characterizing these fragile films on real skin-cosmetic interfaces remains challenging, as they are prone to damage during analysis. Current evaluation methods rely on subjective approaches, such as consumer feedback, color studies, and optical observations, lacking quantitative insights into the relationship between physical properties and sensory experiences. This study introduces X-ray microtomography as a quantitative tool to ex
