Product type
Carboxymethyl Cellulose (CMC) is a cellulose derivative that is widely used as a food additive. It is produced by the chemical modification of cellulose, resulting in a white, odorless powder that is soluble in water. CMC functions primarily as a thickening agent, stabilizer, and emulsifier, helping to improve the texture and consistency of various food products.
| Chemical formula | C8H16O8 |
| Viscosity | 100 to 1000 mPa·s (depending on concentration) |
| Purity | Typically 90% or higher |
| Solubility | Soluble in cold and hot water |
| pH range | 6 to 8 |
When selecting Carboxymethyl Cellulose, buyers should consider the desired viscosity and solubility based on the specific application. It is also important to specify the required purity level and any relevant food safety certifications. Quantities can vary widely depending on production needs, so buyers should assess their usage to request appropriate bulk amounts.
