Methyl Cellulose(MC) is a white, odorless, and tasteless cellulose ether that is soluble in cold water and hot water. It is used in a wide range of industries, including food, pharmaceuticals, construction, and personal care, for its thickening, stabilizing, and binding properties.
MC can undergo thermal gelation, forming a gel that can be used in various applications, such as in food products to create a gel-like texture.
MC has film-forming properties, which makes it useful in the food and personal care industries for creating films or coatings on various products.
MC is biodegradable, meaning it can be broken down by microorganisms in the environment over time. This property makes it a more environmentally friendly option compared to some other synthetic polymers.MC is non-toxic and generally considered safe for use in various industries, including food, pharmaceuticals, and personal care, detergent, building, paint&coatings.
Methyl cellulose (MC) is made by chemically modifying natural cellulose refined cotton, which is the main component of plant cell walls. The process involves reacting cellulose with sodium hydroxide and then with methyl chloride, which results in the addition of methyl groups to the cellulose molecules. The degree of substitution (DS) determines the number of methyl groups that are added to the cellulose molecules and affects the physical properties of the resulting methyl cellulose.
The manufacturing process of making methyl cellulose can be in the following steps:
The natural cellulose is purified to remove impurities, such as lignin and hemicellulose, which can interfere with the chemical modification process.
The purified cellulose is treated with sodium hydroxide to create an alkaline environment that promotes the reaction between cellulose and methyl chloride.
Methyl chloride is added to the mixture of cellulose and sodium hydroxide to react with the hydroxyl groups on the cellulose molecules. This results in the addition of methyl groups to the cellulose molecules, creating the methyl cellulose.
The resulting product is neutralized with an acid to stop the reaction and then washed to remove any remaining impurities.
MC is used as a thickening and stabilizing agent in various food products, such as salad dressings, ice cream, and baked goods. It is also used as a fat replacer and to improve the texture and mouthfeel of food products.
MC is used as a binder, disintegrant, and sustained-release agent in tablet and capsule formulations. It is also used as a viscosity modifier in topical creams and gels.
MC is used as a binder and thickener in cement and mortar formulations to improve their workability and water retention.
MC is used as a thickening and emulsifying agent in various personal care products, such as shampoos, lotions, and cosmetics.
MC is used in various industrial applications, such as in the production of paints, coatings, and adhesives.
