The session aims to provide participants with the opportunity to compare traditional solvents, such as Ligroin, with eco-friendly alternatives like Methyl Myristate and Isopropyl Palmitate, for cleaning metal and polychrome surfaces through direct laboratory activities. Participants will gain practical experience in preparing apolar gels, evaluating the stability and effectiveness of various emulsifiers, and observing the impact on treated surfaces.<\/p><h4><span
