Sodium Carboxymethyl Cellulose (CMC) Process Control

In actual production, the viscosity of a 1% aqueous solution of sodium carboxymethyl cellulose (CMC) is one of the core competitive advantages for a company. Generally, the viscosity of a 1% aqueous solution from food-grade refined cotton is slightly lower than that from industrial-grade refined cotton. A higher viscosity 1% aqueous solution means a more competitive product with the target viscosity.
