CMC is light yellow, odorless and non-toxic powder. It can dissolve in cold water and hot water, it can form the transparent glue liquid. CMC solution assumes neutrality. It does not dissolve in acid, cresol, ethyl alcohol, acetone, chloroform, benzene and so on. It lightly dissolves in methyl alcohol, ether and so on such organic solvent. The solution viscosity increases along with density, and it is of pseudo-plastic flow, light-proof, thermal-proof, water absorbability, non-agglomerate, and anti- salty ability.

In general, the following is the specification of CMC for detergent industry:
thickener for liquid detergents cmc price
| % CMC (Active Content) | 65 - 70 (On Dry Basis) |
| Degree of Substitution | 0.4 - 0.6 |
| pH (1%Solution) | 8.5 - 10.5 |
| Viscosity (4% Solution) | 200 - 2.000 cps |
| % Moisture | 8 - 9 (As Packed) |
For cream type detergents, the viscosity level should be relatively higher.
3. Application
Construction Industry
Used as the water retaining agent and retarder in mortar to make it has good pumpability.
Used as adhesives in plaster, gypsum material, putty powder or other construction materials to improve its workability and extend the operation time.
Textile, Printing, Dyeing Industry
Used in textile, printing and dyeing industry textile industry will CMC as sizing agent, used for cotton, silk, chemical fiber, blending and strong fine gauze sizing.
Papermaking Industry
Used in the papermaking industry CMC in paper industry for paper smoothing agent, sizing agent. Add 0.1% ~ 0.3% of CMC in pulp can make paper strength 40% ~ 50% resistance to tension, compression fracture degree is increased by 50%, and increase 4 ~ 5 times.
Toothpaste Industry
CMC add dirt can be used as adsorbent in synthetic detergent; Glycerin, daily chemical, such as toothpaste industry CMC aqueous solution used as toothpaste gel base; Pharmaceutical industry used as thickener and emulsifier; CMC aqueous solution viscosity after used for flotation and so on.
Food Industry
Used in the food industry, food industry high substitution degree of CMC for ice cream, canned beer, on the surface of the instant thickening agent, foam stabilizer, etc., in the process of jam, sugar juice, fruit, dessert, ice cream beverages as a thickener, binder, or due to the agent.
