Résumé
"Water-Mixable Oil paints (WMOs) were introduced in the 1990s as a less toxic alternative to traditional oil paints. Generally speaking, these paints are manufactured by introducing hydrophilic additives to the linseed oil binder so that the paint is water reducible. As a result, this project operated on the hypothesis that WMOs would be more sensitive to polar solvents than traditional oil paint. Currently, little is known regarding the aging process and behavior of WMOs. This study aims to determine to what extent commonly used solvents might swell and leach components in WMO paint in a typical cleaning scenario. Samples of Winsor & Newton Artisan™ WMO paints and Winton™ linseed oil paints in two colors underwent thermal aging. The samples was immersed in distilled water for 24 hours and in ethanol and acetone for ten minutes. Fourier transform infrared spectroscopy (FTIR) and gas-chromatography (GC-MS) of distilled water, ethanol, and acetone extracts suggested the presence of several fatty acids, including palmitic, stearic, oleic, and azelaic acids. GC-MS of the Artisan paint also found compounds tentatively identified as polyethylene glycols (PEGs), which are known to be used as emulsifying agents. A second set of aged samples were swabbed with the three solvents for approximately one minute. There were significant changes in gloss and color for most of the samples, along with an overall loss of weight. Hardness testing was inconclusive. This study was meant to be an introduction into solvent resistance of WMO paints, and also sought to explore pigment type as potential factors in solvent sensitivity, though due to drying issues, only one pigment was useful in the study. While the ethanol extract removed more components from the Artisan film, analysis of visual changes do not suggest Artisan paint is any more prone to an increase in gloss than Winton films, and may even better resist color change. Further research is needed, but these results may be encouraging to conservators who encounter water-mixable oil paintings in the future."
