Product Description

Methyl cellulose (or methylcellulose) is a chemical compound derived from cellulose. It 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 sold under a variety of trade names and is used as a thickener and emulsifier in various food and cosmetic products, and also as a treatment of constipation. Like cellulose, it is not digestible, not toxic, and not an allergen.

 

Uses[edit]

Methyl cellulose has an extremely wide range of uses, of which several are described below.

Consumer products[edit]

Thickener and emulsifier[edit]

Methyl cellulose is very occasionally added to hair shampoos, tooth pastes and liquid soaps, to generate their characteristic thick consistency. This is also done for foods, for example ice cream or croquette. Methyl cellulose is also an important emulsifier, preventing the separation of two mixed liquids.

The E number of methyl cellulose as food additive is E464 it is also known as hypromellose when used in food.

Methyl cellulose (AKA Methocel produced by Dow Chemical or Mecellose produced by Samsung Fine Chemicals) is also used as paint rheological modifier to prevent paint sagging problem.

Treatment of constipation[edit]

When eaten, methyl cellulose is not absorbed by the intestines but passes through the digestive tract undisturbed. It attracts large amounts of water into the colon, producing a softer and bulkier stool. It is used to treat constipation, diverticulosis, hemorrhoids and irritable bowel syndrome. It should be taken with sufficient amounts of fluid to prevent dehydration.

Because it absorbs water and potentially toxic materials and increases viscosity, it can also be used to treat diarrhea.

A well-known trade name of methyl cellulose when used as a drug is Citrucel by GlaxoSmithKline, but generic versions are also widely available.

Lubricant[edit]

Methyl cellulose is used as a variable viscosity personal lubricant; it is the main ingredient in K-Y Jelly.

Clinical[edit]

The lubricating property of methyl cellulose is of particular benefit in the treatment of dry eyes (Keratoconjunctivitis Sicca).[1] Dry eyes are common in the elderly and is often associated with rheumatoid arthritis. The lacrimal gland and the accessory conjunctival glands produce fewer tears. Methyl cellulose may be used as a tear substitute.

Artificial tears and saliva[edit]

Solutions containing methyl cellulose or similar cellulose derivatives are used as substitute for tears or saliva if the natural production of these fluids is disturbed.

Nutritional supplement capsules[edit]

Methyl cellulose is used in the manufacture of capsules in nutritional supplements, its edible and nontoxic properties provide a vegetarian alternative to the use ofgelatin.

Advanced cookery[edit]

Methyl cellulose, as a gel, has the unique property of setting when hot and melting when cold. The culinary potential of this property is currently being explored at theUniversity of Nottingham.[2]

Construction materials[edit]

Methyl cellulose finds a major application as a performance additive in construction materials. It is added to mortar dry mixes to improve the mortar's properties such as workability, open and adjustment time, water retention, viscosity, adhesion to surfaces etc. Construction grade methyl cellulose is not to be identified with food and pharmaceutical grade methyl cellulose and hydroxypropyl methyl cellulose, since it may be cross-linked with glyoxal for easy dispersion in water.

The construction materials can be cement-based or gypsum-based. Notable examples of dry mixture mortars which utilize methyl cellulose include: tile adhesives, EIFS, insulating plasters, hand-trowed and machine sprayed plaster, stucco, self-leveling flooring, extruded cement panels, skim coats, joint & crack fillers, and tile grouts. Typical usage is about 0.2% – 0.5% of total dry powder weight for dry mixture.

Derivatives of methyl cellulose, which improve upon the performance characteristics, include hydroxypropyl methyl cellulose (HPMC) and hydroxyethyl methyl cellulose(HEMC). These derivatives typically improve the characteristics such as water retention, vertical surface slip-resistance, open time, etc.

Glue and binder[edit]

Methyl cellulose can be employed as a mild glue which can be washed away with water. This may be used in the fixation of delicate pieces of art as well as in book conservation to loosen and clean off old glue from spines and bookboards.

Methyl cellulose is the main ingredient in many wallpaper pastes. It is also used as a binder in pastel crayons and also as a binder in medications.

Paper and textile sizing[edit]

Methyl cellulose is used as sizing in the production of papers and textiles as it protects the fibers from absorbing water or oil.

Cell culture/virology[edit]

Methyl cellulose is also used in cell culture to study viral replication. It is dissolved in the same nutrient containing medium in which cells are normally grown. Asingle layer of cells are grown on a flat surface, then infected with a virus for a short time. The strength of the viral sample used will determine how many cells get infected during this time. The thick methyl cellulose medium is then added on top of the cells in place of normal liquid medium. As the viruses replicate in the infected cells, they are able to spread between cells whose membrances touch each other, but are trapped when they enter the methyl cellulose. Only cells closely neighboring an infected cell will become infected and die. This leaves small regions of dead cells called plaques in a larger background of living uninfected cells. The number of plaques formed is determined by the strength of the original sample.

Bacterial motility inhibitor[edit]

Aqueous methyl cellulose solutions have been used to slow bacterial cell motility for closer inspection. Changing the amount of methyl cellulose in solution allows one to adjust the solution's viscosity.

Stem cell differentiation[edit]

Methyl cellulose is used in the most common approaches to quantify multiple or single lineage-committed hematopoietic progenitors, called colony-forming cells (CFCs) or colony-forming units (CFUs), in combination with culture supplements that promote their proliferation and differentiation, and allow the clonal progeny of a single progenitor cell to stay together and thus form a colony of more mature cells.

Chemistry[edit]

Methyl cellulose is used as a buffer additive in capillary electrophoresis to control electroosmotic flow for improved separations.

Special effects[edit]

The slimy, gooey appearance of an appropriate preparation of methyl cellulose with water, in addition to its nontoxic, nonallergenic, and edible properties, makes it popular for use in special effects for motion pictures and television wherever vile slimes must be simulated. In the film Ghostbusters, for example, the gooey substance the supernatural entities used to “slime” the Ghostbusters was mostly a thick water solution of methyl cellulose. The Aliens ooze and drip a great deal of methyl cellulose—especially the queen.

Methyl cellulose has been used to safely simulate molten materials, as well. In several of the Terminator films, it was back-lit with colored gels and films to reproduce the heated glow of iron in the large pouring ladles used to transport the metal from the smelting ovens to the various molds and forms. Methyl cellulose was also a stand-in for the lava flows on the volcanic surface of Mustafar, in Star Wars Episode III :Revenge of the Sith.
