In the construction sector, HPMC gel is added to tile adhesives to improve their workability, water retention and bonding properties. It ensures a consistent and strong bond between the tile and the substrate.
- Pharmaceutically, HPMC serves as an excipient, playing roles as a binder, disintegrant, and coating agent in tablets. Its mucoadhesive properties make it suitable for controlled drug release systems, ensuring sustained and targeted delivery of medications. Moreover, it is safe for consumption, which is crucial in the formulation of oral and topical formulations.
- The production of HPMC in China has also grown significantly over the past decade. This is mainly due to the increasing demand from the pharmaceutical industry, as well as the government's support for the development of the chemical industry. The Chinese government has implemented policies aimed at promoting the sustainable development of the chemical industry, which has created a favorable environment for the production of HPMC.

Application



9. HPMC in putty powder application, the main role of what, whether chemical reaction?
Hydroxypropyl methyl cellulose meeting the food additive specification is consequently considered safe for all animal species. Setting a maximum content in complete diets is not considered necessary. The low toxicity of celluloses shown in the toxicological studies (see Section 3.2.2) support this conclusion.

A proper identification and characterisation of HPMC as required for a feed additive is not available and the occurrence of potential toxic impurities cannot be assessed.
