CMC Carboxymethyl Cellulose
Carboxymethyl cellulose (CMC) is an anionic water-soluble polymer obtained from cellulose. It possesses excellent thickening, absorption, and water retention properties, and is used in a broad range of applications including food and feed additives, cosmetics, thickening and binding agents, binders, water absorbing materials, and water retention agents. As the material is derived from natural cellulose, it exhibits gradual biodegradability and can be incinerated after use, making it a very environmentally friendly material.

Solubility of Carboxymethyl Cellulose(CMC)
Carboxymethyl Cellulose(CMC) is a natural hydrophilic substance and when sodium carboxymethyl cellulose particles disperse in water, it will immediately swell and then dissolve.
1. Under the condition of stirring, adding sodium cmc slowly helps to accelerate dissolution.
2. Under the condition of heating, adding sodium cmc dispersedly can increase the dissolution rate, but the heating temperature cannot be too high and is appropriate within 50-60°C.
3. If it is used by blending with other materials, first mix the solids together and then dissolve, and in this way, the dissolution speed can also be enhanced.
Add a kind of organic solvents which are insoluble with sodium cmc but soluble with water such as ethanol and glycerin and then dissolve, so in this way, the solution speed can be very fast.
