Sodium Carboxy Methyl Cellulose CAS 9004-32-4 CMC-Na,Healthy Food Additives
Sodium Carboxymethyl Cellulose (Carboxymethyl Cellulose, CMC, Carboxymethyl Cellulose,Sodium Sodium,Sodium salt of Caboxy Methyl Cellulose) is the most widely used and used Cellulose species in the world today.
This product is sodium salt of cellulose carboxymethyl ether, which is anion fiber Plain ether, white or milky fibrous powder or particles, density 0.5-0.7 g/cm, almost odorless, tasteless, hygroscopic. It is easy to disperse into transparent colloidal solution in water and insoluble in organic solvent such as ethanol . When the pH value of 1% aqueous solution is 6.5 ~ 8.5, when the pH value is >10 or <5, the viscosity of glue decreases significantly, and the performance is best when the pH value is 7. For thermal stability, the viscosity rises rapidly below 20℃, and changes slowly at 45℃. Long-term heating above 80℃ can make the colloid denaturation and the viscosity and performance decrease obviously. Soluble in water, transparent solution; It is stable in alkaline solution, easy to be hydrolyzed in the presence of acid, precipitation occurs when pH value is 2-3, and precipitation occurs in the presence of polyvalent metal salts.
