Qingdao Unionchem Co., Ltd. produces sodium carboxymethyl cellulose (CMC) which is a cellulose ether derived from wood or cotton cellulose. CMC is available in a wide range of grades with different viscosities, molecular weights, degrees of substitution, and particle sizes. It functions as a thickener, emulsifier, and texture builder and can be used in food, pharmaceuticals, cosmetics, toothpaste, oil drilling, paper making, textiles, ceramics, and other industries. CMC has high viscosity, clarifies solutions, controls rheology, and improves adherence, salt resistance, and acid resistance.

Sodium Carboxymethyl cellulose
Sodium Carboxymethyl cellulose, CMC, is the sodium salt of carboxymethyl
cellulose,is a cellulose ether derived from wood and/or cotton cellulose.A wide
range of cellulose gum grades with different viscosities,molecular weights,degress of
substitution and particle sizes are available and product can be customized to meet
specific needs and applications.
CMC is high viscosity clarified solution hydrocolloid,function as thickening rheology
control,emulsifier,texture building,suspension, improve adherence,salt resistance
and acid resistance,etc.With these important characteristics,CMC can be used in
Food,Pharma.Cosmetic,toothpaste, oil drilling,paper-making,textile,ceramic,etc.in
many industries.
Typical properties:
Degree of substitution
Carboxymethyl cellulose Higher degree of substitution impact the rheology of the
aqueous solution and give improved compatibility with other solutes in the system.
Degree of substitution range:
1) 0.70-0.90
2) 0.90-1.20
