Evaluation of Green Solvents’ Applicability for Chromatic Reintegration of Polychrome Artworks

Organic solvents are commonly used in restoration treatments, including chromatic reintegration on polychrome artworks. They often toxic, and their vapors have a high impact the environment restorers, possibly causing pathological conditions. Therefore, this study aims at defining new green solvent that can be for reintegration, maintaining volatility desired physical–chemical properties. The dispersion forces value (Fd) of ethyl lactate was taken as reference comparison with proposed solvents, since it found to most dilution Maimeri Restoration Colors (MRC) Gamblin Conservation (GCC). Based Teas fractional parameters, six solutions based acetals ethanol been tested. were mixed both MRC GCC, applied prepared canvases. difference between backgrounds made one alternatives evaluated through spectrocolorimetric measurements.
