Microcrystalline cellulose is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and is approved for use in both food and pharmaceutical products. Its non-toxic nature and inertness make it a favorable option compared to alternative excipients.

Sodium carboxymethyl cellulose (CMC) is a widely used food additive with various functional properties that play a crucial role in the food industry. It is a derivative of cellulose, which is a natural polymer obtained from plant cell walls. CMC has garnered attention due to its unique properties such as thickening, stabilizing, emulsifying, and gelling, making it an essential ingredient in many food products. This article explores the uses, benefits, and safety aspects of sodium carboxymethyl cellulose in food.

The effectiveness of polycarboxylate ethers comes from their unique mode of action. When added to a concrete mixture, PCEs reduce the viscosity of the cement paste by acting as dispersants. They achieve this by adsorbing onto the surface of cement particles, creating a negative charge that causes the particles to repel each other. This electrostatic repulsion minimizes particle agglomeration, leading to better dispersion and improved workability of the concrete.
