PRODUCT INTRODUCTION
description
Methyl cellulose polymer consisting of numerous linked glucose molecules used as a stabiliser, thickener and emulsifier for foodstuffs and cosmetics. The Degree of Substitution (DS) of a given form of methyl cellulose is defined as the average number of substituted hydroxyl groups per glucose with a theoretical maximum of 3, however more typical values are 1.3 2.6. Methyl cellulose is a hydrophilic white powder in pure form and dissolves in cold (but not in hot) water, forming a clear viscous solution or gel. It is available under a variety of trade names as a treatment for constipation. Like cellulose, it is not digestible, not toxic, and not allergenic
