KimaCell®MC A4M Methylcellulose integrates many physical and chemical reactions and becomes a unique product with multiple uses. Cellulose can be produced from wood pulp or cotton, which itself is not soluble in water, but it is strengthened with alkali, etherified with methylene chloride and propylene oxide, washed with water, and dried to obtain water-soluble methyl cellulose (MC), that is, the hydroxyl groups on the C2, C3 and C6 positions of glucose are replaced with methoxy and hydroxypropoxy to form nonionic cellulose ethers.

Methylcellulose solution is stable to alkalis and alkenoic acids at pH 3-11 at room temperature. At pH below 3, the glucose-glucose bond is hydrolyzed due to acid catalysis and results in a decrease in solution viscosity. When heated, the viscosity of the solution decreases until, at about 50°C, a gel is formed.
Methylcellulose is susceptible to spoilage by microorganisms, so antimicrobial preservatives should be used. The solution can also be autoclaved, although this process reduces the viscosity of the solution. After autoclaving, the change of solution viscosity is related to the solution pH. Solutions with a pH below 4 had a viscosity drop of more than 20% after autoclaving.
