Although the use of cellulose ethers in conservation is widespread, literature provided by the manufacturers of these materials lacks critical information. This study reviews the physical and chemical properties of cellulose ethers and reports on their thermal and photochemical long-term stability. The relative hierarchy of cellulose ethers with respect to thermally induced discoloration, loss of weight, degree of polymerization, and formation of peroxides is evaluated. This study was a joint effort of the Mellon Institute at Carnegie Mellon University and the Getty Conservation Institute.
