use of hydroxyethyl cellulose.
- In the construction industry, Celulosa HPMC is used as a thickening agent in cement-based products such as mortars, grouts, and renders. It improves workability, adhesion, and water retention, making it easier to apply and enhancing the overall performance of the product. Additionally, it can reduce the risk of cracks and shrinkage in the final cured product.
- Introduction
- MHEC-METHHYL Hydroxyethyl Cellulose Factory is a state-of-the-art facility dedicated to the production of this versatile and widely used polymer. This article provides an in-depth look at the factory's operations, including its history, production processes, and environmental sustainability initiatives.
- HPMC is insoluble in water but can dissolve in a variety of organic solvents such as alcohols, acetone, and ethylene glycol. The degree of solubility depends on factors such as the type and concentration of the solvent, the molecular weight of HPMC, and the pH of the solution. For example, lower molecular weight HPMC tends to be more soluble in organic solvents than higher molecular weight HPMC.
- The thermal stability of HPMC is another standout feature. It remains stable up to high temperatures, which is crucial in processes like hot melt extrusion. Its non-flammability also adds to its safety profile in manufacturing processes Its non-flammability also adds to its safety profile in manufacturing processes

hpmc properties.
- The solubility of HPMC in water is influenced by several factors, including temperature, pH value, and the concentration of the polymer. Generally, HPMC dissolves more easily in cold water than in hot water. This is because the hydrogen bonds between the polymer molecules are stronger at higher temperatures, making it more difficult for the molecules to separate and dissolve in the solvent.





The following conclusions apply only to HPMC meeting the food additive specifications.


What is HPMC?
Characterized as off-white, HPMC is a cellulose polymer that has undergone chemical modification but is still considered to be safe for consumption by people. Full formulae written as Hydroxypropyl methylcellulose is a non-toxic, odorless, water-soluble polymer that is used in many industries for its hydrophilic properties. It is also used as a food additive in the US and cosmetics for its moisturizing and smoothing effects. It should be noted that Hydroxypropyl methylcellulose cannot be digested by the human digestive system and passes through the digestive tract as it is.


In the rabbit hindgut, fermentation occurs through a wide prevalence of Bacteroides that do not allow an extended digestibility of fibre. Digestibility of cellulose was shown to amount to 16% of the administered dose, whereas values of 14% and 18% were reported for fibre (cellulose being the main component) (review from the NRC, 1977). Later studies reported values comprised between 15 and 25% in rabbits administered different plant sources of cellulose (Gidenne and Perez, 1996; Chiou et al., 1998). In the horse, digestion of plant structural carbohydrates (including cellulose) occurs in the hindgut (colon and overall caecum). The microbiota of the caecum comprises bacteria similar to those of the rumen, but specific protozoa. The resulting digestibility is about two-third that measured in ruminants.
In the construction industry, Hydroxypropyl Methylcellulose plays a crucial role due to its remarkable properties:
