In the UK it was submitted by Dow (who manufacture HPMC for the global food market) for approval to the Advisory Committee on Novel Foods and Processes in November 2011.
The solubility of HEC in cold water is typically slow, often requiring agitation or heating to facilitate dissolution Distributors often maintain a comprehensive inventory, catering to diverse customer needs. They offer different grades of HPMC, each tailored for specific applications. For instance, the construction industry might require a grade that enhances the viscosity of cement mixtures, while the pharmaceutical sector might need one that aids in tablet coating. The selection of the appropriate HEC viscosity and concentration depends on the specific application requirements The temperature factor also significantly impacts HPMC's solubility. As the temperature increases, the solubility of HPMC in water generally improves As the temperature increases, the solubility of HPMC in water generally improvesHPMC gel is used in pesticide product formulations to enhance the adhesion of active ingredients to plant surfaces and improve the efficacy of pesticides.
In addition to its applications in oral solid dosage forms, HPMC is also used in ophthalmic preparations, nasal sprays, and topical formulations. In ophthalmic preparations, HPMC is used as a viscosity-enhancing agent to improve the retention time of the drug on the ocular surface and enhance its bioavailability. In nasal sprays, HPMC helps to improve the viscosity of the formulation and promote the absorption of the drug through the nasal mucosa. In topical formulations, HPMC can act as a stabilizer and emulsifying agent to improve the stability and shelf-life of the product. Moreover, redispersible polymer powder offers significant improvements in workability and water retention Cellulose ether HPMC, also known as hydroxypropyl methylcellulose, is a versatile and essential ingredient。,,。The rheological properties of HPMC gel make it suitable for use in self-leveling compounds, ensuring uniform and smooth surfaces in flooring applications.
Another important factor to consider when choosing an HPMC grade is its degree of substitution (DS). DS refers to the number of hydroxyl groups on the cellulose molecule that have been substituted with hydroxypropyl groups. A higher DS means that more hydroxyl groups have been replaced, resulting in a more hydrophilic polymer. This property makes high-DS HPMC suitable for applications that require water-soluble films or coatings, such as in the pharmaceutical industry.Celopro ME
with a variety of drugs. Its ability to function as a binder, sustained-release When purchasing, ensure to check the product specifications, such as viscosity, molecular weight, and degree of ethoxylation, as these factors can significantly influence the performance of HEC in your application. Also, don't forget to inquire about certifications (e.g., GMP, ISO) and any relevant safety data sheets (SDS). Due to its tailored chemical structure, HPMC finds extensive use in various industries. In pharmaceuticals, it serves as an excipient for controlled drug release and tablet binding. In construction, it's a common ingredient in dry mixes due to its ability to form a gel when mixed with water, improving the workability and setting properties. It's also utilized in the food industry as a thickener, emulsifier, and stabilizer, and in the paint sector as a film-former and rheology modifier.The present assessment is based on data submitted by the applicant in the form of a technical dossier5 in support of the authorisation request for the use of HPMC as a feed additive.
