What are the characteristics of hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether widely used in food, medicine, construction and other fields. It is made from natural cellulose through chemical processing such as alkalization and etherification, and has the following main characteristics:

4. Environmental and biocompatibility

Environmental protection: HPMC is a biodegradable material that is environmentally friendly.

Biological safety: As a food and drug additive, it has good biocompatibility and is non-toxic and harmless.

 

5. Adjustability of physical properties

The properties of HPMC (such as viscosity and gel temperature) can be adjusted by adjusting its degree of substitution (the content of methoxy and hydroxypropyl groups) to meet different application requirements.

 

6. Chemical resistance

Salt resistance: It is stable in a certain concentration of salt solution.

Enzymatic resistance: Compared with natural cellulose, HPMC has stronger resistance to enzymatic hydrolysis.

 

Hydroxypropyl methylcellulose has been widely used in many industries such as food, medicine, and construction due to its excellent physical and chemical properties, multifunctional characteristics, and wide applicability. Its unique water solubility, thickening, water retention, and film-forming properties make it an irreplaceable and important material.
