Agar gel loaded with micro-emulsion could be used to extract Day cream lipophilic materials from porous surfaces.The physical properties of the gels are good enough for a conservation work.They allow the micro-emulsion to flow on the porous surface and to wet it but maintain the micro-emulsion in its Pastry Brush structure and prevent the formation of rings.The evaporation of the solvents is slowed down and the gels can be used during a long period.
