Hydroxyethyl cellulose (HEC) and Exilva microfibrillated cellulose (MFC) can both be used as rheology modifiers in a variety of industries to prevent sedimentation and settling. In this article, I review the ability of the materials to give a yield stress in a waterbased system and, because of that, provide anti-settling and anti-sedimentation behavior. Tune-in on a comparison between these two rheology additives.

Among the many potential applications of cellulosic nanomaterials, one of the most promising is the use of microfibrillated cellulose (MFC) to enhance the surface of paper products. The vast majority of paper products, from cardstock to fast-food packaging, receive some type of functional coating during manufacturing to improve end-use performance. Coatings can impart many different properties to paper products, including water, oil and grease resistance, reproduction quality, absorbency and smoothness. Many different materials are used to coat paper surfaces ranging from minerals, natural and synthetic binders, and polymers.
