What Is METHOCEL™?

IFF’s METHOCEL™ cellulose ethers are multifunctional, plant-based ingredients that provide thickening, rheology modification, stability, and film-forming properties in a vast number of chemical formulations. These formulations constitute various products in industries such as paints, adhesives, cleaners, ceramics, agriculture, food, pharmaceuticals, and cosmetics. Noting the abundance of the different applications METHOCEL™ can be used in, formulators have several grades to choose from to customize for viscosity, solubility, and food-contact requirements.

Chemically, METHOCEL™ consists of either methylcellulose (MC) or hydroxypropyl methylcellulose (HPMC), both of which are water-soluble polymers derived from cellulose that comes from natural wood or cotton linters.

METHOCEL™ is also used as an ingredient in several food, pharmaceutical, and personal care applications to leverage many of the same functionalities listed above. It also finds use as a thickener to create the necessary viscosity to simulate solutions for medical research, theatrical props, and more. Being derived from cellulose, METHOCEL™ imparts bio content in formulations and provides a future-focused advantage in terms of driving product sustainability.

Why should I consider using METHOCEL™?


Many products on the market may offer one or more similar functionalities to those of METHOCEL™. However, none possess as many unique properties as METHOCEL™ does, which combine to improve value and functionality in an array of applications. Below is a list of properties that make METHOCEL™ uniquely valuable.

  • Shear-thinning rheology modification

  • Reversible thermal gelation

  • Viscosity control from 15 cPs to 120,000 cPs

  • Stabilization of suspensions and emulsions

  • Consistent performance in solutions ranging from pH 3 to 11

  • Solubility in water and various organic solvents

  • Derived from plant-based materials

How do I use METHOCEL™?


METHOCEL™ cellulose ethers are sold in powdered form and must be dissolved completely in water or solvent prior to creating a solution to yield the best results—review procedures for dissolution and activation of METHOCEL™ here.

How do I select a METHOCEL™ grade?


METHOCEL™ grades are primarily selected based on the viscosity and degree of substitution required in each application. METHOCEL™ grades can be added to solutions to control viscosity within a range of 15 to 120,000 cPs. Viscosity control is largely a function of the METHOCEL™ grade’s molecular weight, where higher–molecular weight grades offer more pronounced shear-thinning properties. METHOCEL™ grades also have varying degrees of methyoxyl and hydroxypropyl functional group substitution. This variability influences the cellulose ether’s solubility within organic solvents and its thermal gelation temperature. More information about grade selection can be found in this product article.
