Application
Soluble carboxymethylcelluloses (CM-cellulose; CMC) available in varying viscosities are used as viscosity modifiers (thickeners) to stabilize emulsions and as a chemical dispersants of oils and other carbon structures such as nanotubes. CMCs are used in the development of biostructures such as biofilms, emulsions and nanoparticles for drug delivery.

Glycerol and oleic acid (OA) were incorporated into carboxymethyl cellulose (CMC) films by an emulsification method. Films containing different amounts of glycerol and OA were examined for mechanical properties, water vapor permeability (WVP), and moisture uptake, optical and thermal properties.
