General description

Methyl cellulose is a gum polysaccharide containing glucose with methyl substitution.

Application

Methyl cellulose has been used:


  • in polymer solution to enhance viscosity in the formulation for dip coating
  • in growth medium to facilitate stable morphology
  • as a supplement in HMI-9 medium to increase viscosity

Biochem/physiol Actions

Methyl cellulose is known to have a molecular size that might pass through placenta. It is useful in visualizing small bowel loops through its overlaps.

Questions

  1. What is the difference chemically speaking and in characteristics of these two compounds? Regarding particle size and its properties, Cat # 94378 Methocel® A4M vs M0512 Methylcellulose both have the same CAS Number: 9004-67-5

    1 answer

    1. Product 94378 (Methocel® A4M) in a 2% solution in water at 20°C results in a solution with a viscosity between 3000 - 5500 mPa.s. While not directly analyzed for particle size, it is suggested that it is primarily -40 mesh or smaller than 420 micron. Molecular weight information is not determined.

      Product M0512 in a 2% solution in water at 20°C results in a solution with a viscosity between 3500 - 5600 cps. The particle size for product M0512 is not analyzed. The M0512 lists an approximate molecular weight of 88,000 with methoxy substitution between 27.5 - 31.5% (weight).

      https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/251/785/m0512pis.pdf

      Both products are methyl cellulose polymers. The major application that Dupont lists for their Methocel A4M is in ceramic extrusion. It seems to have a similar reported methoxy content as shown in Dow's brochure below.

      https://cms.chempoint.com/ChemPoint/media/Methocel-brochure/Methocel-Brochure-2019-1.pdf

      Thus, the primary difference between these two products would be the manufacturer's origin.
