The Difference between HPMC, CMC, and MC

Nov. 22, 2024

Many customers often find it challenging to differentiate between HPMC, CMC, and MC, even though all three are popular cellulose derivatives

with distinct characteristics. Here, we aim to highlight the key differences among these products.

1. Hydroxypropyl Methyl Cellulose (HPMC)

Hydroxypropyl Methyl Cellulose (HPMC) is a modified form of cellulose, enhanced with hydroxyl and methyl groups. It serves as a versatile ingredient,

widely used as a food additive and a thickening agent in various applications, including cosmetics, pharmaceuticals, and construction materials.

2. Sodium Carboxymethyl Cellulose (CMC):
Sodium Carboxymethyl Cellulose, commonly known as CMC, is an effective thickener and emulsifier. Its key specifications include purity, viscosity,

and the degree of substitution (D.S.).CMC is extensively used in food products such as jams, ketchup, milk, juices, yogurt, and ice cream.

It enhances mouthfeel and extends shelf life.

In the detergent industry, sodium CMC is utilized in both liquid and powder detergents. When used in liquid detergents, it can be combined with

xanthan gum to stabilize the liquid system over time, preventing phase separation.

In the paper-making industry, CMC functions as a wet-end additive to improve paper strength and as a sizing agent for coated paper.

3. Methyl Cellulose (MC):
Methyl Cellulose (MC) is a versatile thickener, dispersant, and adhesive commonly used in industrial, food, and pharmaceutical applications.

It finds extensive use in building construction materials (e.g., cement), textile sizing and dyeing, and paper-making.

In cement slurry, MC enhances water retention on ceramic surfaces and helps prevent wall cracks. Additionally, it is employed as an emulsifier,

film-forming agent, and suspending agent in pharmaceutical and food products, including tablets, capsules, oral liquids, and injectable drugs.
