East Chem Methyl Cellulose (MC)

Methyl Cellulose (abbreviated as MC) is a non-ionic cellulose ether. The following is a detailed introduction to it:
Basic Information
Chemical formula: (C6H7O2 (OH) 3 - x (OCH3) x) n, where x represents the degree of substitution of methoxy groups, and n represents the degree of polymerization.
Appearance: Usually it is a white or off-white fibrous or granular powder.
Odor: Odorless and tasteless.
Physical and Chemical Properties
Solubility: It can swell in water to form a clear or slightly turbid colloidal solution
Thermal stability: It has good thermal stability and can maintain its physical and chemical properties stable within a certain temperature range.
Viscosity: Its aqueous solution has a certain viscosity, and the viscosity varies with factors such as concentration and temperature. Generally speaking, the higher the concentration, the greater the viscosity; as the temperature rises, the viscosity decreases.
Application Fields
Food industry: As a thickener, stabilizer, emulsifier, etc., it is used to improve the texture and taste of food and extend the shelf life of food. For example, in ice cream, it can prevent the formation of ice crystals and make the taste more delicate; in baked goods such as bread and cakes, it can retain moisture, delay aging, and extend the shelf life.
Pharmaceutical industry: It can be used as an excipient for pharmaceutical preparations, used to prepare tablets, capsules, eye drops, etc. In tablets, it can be used as a binder to make the drug powder agglomerate into granules, facilitating tableting; in eye drops, it can increase the viscosity of the solution, prolong the residence time of the drug in the eyes, and improve the curative effect of the drug.
Construction industry: It is used to prepare building putties, coatings, tile adhesives, etc. It can improve the water retention, adhesion and construction performance of these materials, making the construction more convenient. At the same time, it can also enhance the water resistance and durability of the materials.
Cosmetics industry: It is often used as a thickener, stabilizer and emulsifier in cosmetics, such as lotions, creams, shampoos, etc. It can improve the texture of cosmetics, making them more delicate and uniform, and easy to apply and use.
Safety: Methyl cellulose is generally considered a safe food additive and pharmaceutical excipient. Within the normal range of use, it is non-toxic and non-irritating to the human body. However, if ingested in excessive amounts, it may cause symptoms such as gastrointestinal discomfort.
