CMC is used as a lubricant in non-volatile eye drops (artificial tears).Carboxymethylcellulose is prepared from cellulose, the main polysaccharide and constituent of wood and all plant structures. Commercially prepared from wood and chemically modified. No known adverse effects but it could be produced from genetically engineered cotton plants. Known to cause cancer when ingested by test animals. Many different uses, mainly as thickening agent, but also as filler, dietary fibre, anti clumping agent and emulsifier.
