HEC-100000 is widely used in the construction industry as a key additive in cement-based materials. It enhances the workability and water retention of mortar and concrete, ensuring better adhesion and reduced cracking during the curing process. This makes it particularly valuable in applications like tile adhesives, self-leveling compounds, and plastering.

In the paint and coatings industry, it acts as a thickener and stabilizer, improving the viscosity and texture of water-based paints. This results in smoother application, reduced splattering, and better coverage on surfaces. It also helps prevent pigment settling, ensuring consistent color throughout the product's shelf life.

In personal care products, it is utilized as a thickening and emulsifying agent in formulations like shampoos, conditioners, and lotions. It provides a smooth, creamy texture and enhances the stability of the product, ensuring even distribution of active ingredients.

Additionally, it finds application in the pharmaceutical industry as a binder and controlled-release agent in tablet formulations. It helps maintain the integrity of the tablet while regulating the release of active pharmaceutical ingredients for optimal therapeutic effects.

In the food industry, it serves as a thickener and stabilizer in products such as sauces, dressings, and other viscous formulations, improving texture and preventing separation.
