However, methylcellulose-contrast enteroclysis also has several disadvantages. Methylcellulose is a thick sticky substance that may require dilution in the "barium kitchen." Bubbles will form if methylcellulose is shaken, not stirred. Methylcellulose is messy and difficult to instill unless an electric pump is used. Excessive consumption of cellulose fiber may cause side effects such as Bloating. Nausea. Gas. Methyl cellulose is synthetically produced by heating cellulose with an acidic solution (e.g., a sodium hydroxide solution) and treating it with methyl chloride. The compound does not occur naturally. It is manufactured by reacting alkali cellulose with propylene oxide at elevated pressure and temperature to yield a highly substituted cellulose ether with 3.4–4.1 mol of hydroxypropyl substituent per mole of anhydroglucose backbone units (Ashland, 2001).
You are considered to be non-toxic. Use as a food additive indicates good tolerance of small amounts, but excessive amounts or overuse may bring irritant and harmful effects. Hydroxypropyl Cellulose/Pluronic-Based Composite Hydrogels as Biodegradable Mucoadhesive Scaffolds for Tissue Engineering. Hydroxypropyl Methylcellulose is easily soluble in cold water but difficult to be soluble in hot water. However, its gelling temperature in hot water is significantly higher than that of Methyl Cellulose (MC). And compared with MC, the dissolution in cold water has also been greatly improved. High levels of cellulose are found in the root and leafy vegetables, legumes, and some fruits such as pears and apples. Lignin content is highest in fruits, particularly strawberries, and peaches, whereas pectin levels are highest in citrus fruits and apples.
