In present work, novel xylene-in-water microemulsion based on nonionic surfactants with low toxicity was obtained, designed as low-impact cleaning agent for metallic historic objects. Phase diagram mixtures containing polyoxyethylene-polyoxypropilene triblock copolymer Pluronic P84 D-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS) surfactants, water, ethanol xylene studied, surfactant content selected suitable nanosystem. Essential oils (EOs) from thyme cinnamon leaf were added order include other beneficial properties such anticorrosive antifungal protection. The microemulsions or without EOs characterized by size, size distribution zeta potential. efficacy tested assessed their ability remove two types artificial dirt using X-ray energy dispersion spectrometry (EDX), scanning electron microscopy (SEM), contact angle measurements color analysis. Microemulsions exhibit high capacity model copper coupons spite very organic solvent. Both oil loading prove significantly reduce corrosion rate treated plates compared those bare copper. activity type evaluated against Aspergillus niger, reported main treat biocorrosion artifacts.

The transition toward sustainable conservation practices requires a scientifically ground approach to substituting traditional solvent systems with green alternatives. This study aims facilitate the adoption of solvents by restoration professionals systematically evaluating their chemical compatibility and toxicological safety. By integrating Hansen solubility parameters (HSP), Relative Energy Difference (RED), Integrated Toxicity Index (ITI), we identified high potential for replacing Cremonesi mixtures. analysis revealed that ether-based solvents, such as 2,5-dimethyltetrahydrofuran cyclopentyl methyl ether, exhibit affinity mixtures, while esters fatty acid (FAMEs) offer balanced combination low toxicity. However, also underscores significant gaps in safety data (SDS) many innovative highlighting need further evaluation before widespread implementation.
