Methylcellulose
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 used in a variety of industries, including food and pharmaceuticals.
Chemical Structure[edit | edit source]
Methylcellulose is a cellulose derivative with the hydroxyl groups of the cellulose replaced with methyl groups. The degree of methylation and the uniformity of methylation can be controlled during the manufacturing process. The number of methyl groups present per anhydroglucose unit is referred to as the degree of substitution (DS), which can range from 1.3 to 2.6.
Properties[edit | edit source]
Methylcellulose has a unique property of gelation when heated. It dissolves in cold water to form a clear or slightly opalescent colloidal solution. It has a high viscosity, which can be modified by changing the degree of methylation.
Uses[edit | edit source]
Methylcellulose has a wide range of uses due to its properties. It is used as a thickener and emulsifier in various food and cosmetic products, and also as a treatment of constipation. In pharmaceuticals, it is used as a binder and coating agent in tablet formulations.
Food Industry[edit | edit source]
In the food industry, methylcellulose is used as a thickener and stabilizer in sauces, ice creams, and other processed foods. It is also used as a fat substitute in low-calorie foods.
Pharmaceutical Industry[edit | edit source]
In the pharmaceutical industry, methylcellulose is used as a binder in tablet formulations, helping to ensure that the tablet remains intact after it is formed. It is also used as a coating agent, providing a smooth finish to tablets and helping to mask unpleasant tastes.
Medical Uses[edit | edit source]
Methylcellulose is used in the treatment of constipation. It works by increasing the bulk in your diet, which helps to move stool through the intestines.
