Carboxy methyl cellulose is one of cellulose derivatives. This substance, which is called CMC for short, has carboxy methyl groups attached to some hydroxyl groups of cellulose monomers, i.e. glucopyranoses. CMC is a water-soluble anionic polymer obtained from the cellulose of wood fragments and plant cell walls.
This substance is a cellulose ether that is produced by the reaction of alkaline cellulose with sodium monochloroacetate under controlled conditions. It is used as a thickener, adhesive, stabilizer, emulsifier, viscosity controller, and also a chemical solution flow controller.
Since this chemical is obtained from natural cellulose, it can be biologically decomposed and is very compatible with the environment.
