New perspectives have been opened by the application of self-assembled systems to Conservation, generating a breakthrough in the development of innovative tools for the conservation and preservation of cultural heritage. This contribution is an overview of the most recent methodologies developed in the Conservation field, focusing on amphiphilic systems, and gels. We report on the characterization of two systems, EAPC and XYL, which have shown good to optimal performances in the removal of organic polymers from wall paintings. EAPC is a five-components fluid composed of water, sodium dodecylsulfate (SDS), 1-pentanol (PeOH), propylene carbonate (PC), and ethyl acetate (EA), while XYL is a �classical� o/w microemulsion where p-xylene droplets are stabilized in water by SDS and PeOH. Small-angle neutron scattering (SANS) with contrast variation is used to infer a detailed picture of the structure of these complex fluids. We found that the composition and the structure at the nanoscale determine the capability of removing a broad range of different polymer coatings from porous materials.@No kinship exists among authors
