Description: A white, yellowish white, or greyish white powder or loose, cotton-like, fibrous material; odourless. Solubility: Practically insoluble in hot water, ethanol (~750 g/l) TS, ether R, and acetone R; soluble in glacial acetic acid R and in a mixture of equal volumes of ethanol (~750 g/l) TS and chloroform R. Category: Coating agent; viscosity-increasing agent; tablet binder.Storage: Methylcellulose should be kept in a well-closed container. Labelling: The designation on the container of Methylcellulose should state its viscosity. Additional information: Methylcellulose is hygroscopic after drying. In cold water it swells and produces a clear to opalescent, viscous, colloidal suspension which is neutral to litmus R.Definition: Methylcellulose is a methyl ether of cellulose.Methylcellulose contains not less than 26.0% and not more than the equivalent of 32.0% of methoxy (-OCH3) groups.
