Does anyone know what's CMC and where I can buy it?

Thank you girls for your help!!!!!!!!

CMC (carbomethylcellulose) is synthetic gum tragacanth, it's used for binding gumpaste. You can buy it at: s u g a r c r a f t .com/catalog/gumpaste/gp-doughs.htm

Also called tylose or tylo powder. Its effetcs are faster than those of tragacanth gum.
