(New Tools and Techniques: Let’s Talk about Gels!) Using Polymeric Emulsion Stabilizers

Gelling aqueous and non-aqueous cleaning systems allows the conservator to control permeation of the solution into the substrate. Polymeric gelling agents give us the control of solution viscosity. But above and beyond simply gelling a cleaning system, polymeric emulsion stabilizers allows the conservator to create emulsion systems that yield very powerful and subtle cleaning systems without having to add surfactants. Nonpolar solvents dispersed in an aqueous continuous phase allow the use of less solvent -- safer and greener. Dispersing polar systems, particularly water, into a continuous phase of silicone solvent or a mixture of silicone and aliphatic solvents often allows water-sensitive surfaces to be treated safely.
