First-Aid Measures

4. Air-Entraining Agents These additives create tiny air bubbles within the mortar, improving its resistance to freeze-thaw cycles and enhancing its workability.

Potential Side Effects

In recent years, the trend towards sustainable construction practices has also influenced the use of mortar bonding agents. By improving the longevity and performance of structures, these agents help reduce waste and resource consumption over time.

Applications Beyond Pharmaceuticals and Food

Viscosity in Hydroxyethyl Cellulose

1. Pharmaceuticals In the pharmaceutical sector, HEC is commonly used as a thickening agent, emulsifier, and stabilizer. It plays a crucial role in enhancing the viscosity of topical formulations, such as creams and ointments, ensuring a smooth application. Additionally, HEC is utilized in drug delivery systems, where its biocompatibility and controlled viscosity help in the release of active ingredients in a regulated manner.

The thickening mechanism of HEC is primarily based on its ability to interact with water and form a gel-like structure. When HEC is dissolved in water, it hydrates and swells, resulting in an increase in viscosity. The thickening effect can be attributed to the following key factors
