Cellulosics, such as HPMC (Hydroxypropyl Methylcellulose), HEC (Hydroxyethyl Cellulose), HEMC (Hydroxyethyl Methylcellulose) and CMC (Carboxymethylcellulose), can be either pure or modified, and are widely used as functional additives in various industrial formulations. They stand out for their ability to modify essential properties in formulations, such as viscosity, water retention, adhesion and stability.
