Technical CMC 75a is divided into different types, which differ in the following parameters:

Purity: different salt contents
Viscosity: Measure of the viscosity of a fluid
Average degree of substitution: Average proportion of the etherified hydroxyl groups per polymer building block of cellulose (anhydroglucose) by a carboxymethyl group.

The parameters of the respective type described above determine the field of application, which is very versatile due to the properties and functions resulting from it.

Features:

• Nontoxic
• Thickening, binding (water etc.) and gelling
• Emulsifying
• Suspending
• Surface active
• Adsorptive

Due to its multitude of properties and functions, It is used in a wide variety of economic sectors.
