- Manufacturers of MHEC are committed to delivering consistent and reliable products through innovative production methods and rigorous quality control processes. These companies often boast state-of-the-art facilities equipped with cutting-edge technology, ensuring the optimal extraction and modification of cellulose from natural sources like wood pulp or cotton linters. The synthesis process involves etherification, where methyl and hydroxyethyl groups are chemically attached to the cellulose backbone, creating the unique characteristics of MHEC.
Also known as Hypromellose or HPMC



Appearance and Properties: White or quasi-white fibrous or granular powder






What is HPMC gel used for?
Answer: HPMC serves three functions in putty powder: thickening, water retention, and facilitating construction. It does not participate in any chemical reactions. The reasons for bubble formation are as follows:
As with any ingredient, manufacturers must adhere to recommended dosage levels and quality standards to ensure the safety and effectiveness of the final product. Consumers should also follow recommended dosage instructions provided by their health care professional or as directed on the product label.
Hydroxypropylmethyl cellulose is a cellulose ether with both methyl and hydroxypropyl functional group substitutions. Hydroxypropylmethyl cellulose (HPMC) is a nonionic thermoplastic polymer that dissolves in water to produce a solutions with a wide range in viscosity. It has greater gelling capacity than hydroxypropyl cellulose (HPC) and is more tolerant to salts and additives. HPMC is used as a thickening agent, stabilizer, emulsifier and film forming agent. Aging studies indicate that HPMC has very good stability with negligible discoloration or weight loss (Feller and Wilt 1990).
Substitution of cellulose with ethyl-, methyl-, hydroxypropyl-, hydroxypropyl-methyl- and carboxymethyl groups may increase the resistance of cellulose to degradation. Resistance increases with the degree of substitution and is greatest when the substituent groups are evenly dispersed along the polymer chain. Most cellulose of the additive under assessment will therefore pass the intestine undigested and will excreted unchanged via faeces. Even when a high cellulolytic activity is present, as in the rumen, ethyl cellulose remains sufficiently resistant to degradation to be used as enteric coatings designed to protect methionine from rumen release (EFSA FEEDAP Panel, 2012c). Subsequent degradation in the post-ruminal tract is most likely to lead to high molecule weight breakdown products, with little probability of absorption.
The mechanism of action of Hydroxypropyl Methylcellulose is a result of its unique molecular structure. HPMC is a cellulose derivative with hydrophilic hydroxypropyl and methyl groups attached to the cellulose backbone. When added to a formulation, HPMC disperses in water to form a colloidal solution.
