Culminal® methylcellulose and MC derivatives

Culminal® methylcellulose derivatives are cellulose ethers that, when dissolved in cold water or solvent, offer a variety of functional properties. Culminal products are typically supplied as granular powders. Culminal products are nonionic cellulose ethers and compatible with many surfactants and polymers such as starch, guar and alginates. Solutions of Culminal are pseudoplastic; some show thixotropy. Their solution viscosity is dependent on the temperature. As the solution temperature increases, the viscosity initially decreases. When reaching a type-specific gelling temperature, gelling and flocculation of the products will occur. This process is reversible upon cooling.

Chemically, Culminal products are ethers of cellulose and methylchloride, ethylene oxide or propylene oxide. These cellulose derivatives have been designated as follows:
