[Union Carbide] A registered trademark for a series of translucent polyethylene glycols and methoxypolyethylene glycols. The water-soluble Carbowax® products are available in a range of viscosities from a honey-like solution to a hard wax-like block. They are used commercially as solvents for dyes, natural resins, and proteins. They are also used as plasticizers for casein, gelatin, glue, zein, cork, and inks. Carbowax® formulations have also been used to slowly replaced water in water-logged wood providing structural support while decreasing wetness. They, however, remain somewhat tacky and can retain dirt that darkens and discolors the artifact.
