An aqueous solution of HEC is a non-Newtonian fluid, and its viscosity changes as the shear rate changes.
The viscosity increases as the shear rate decreases, while the viscosity decreases as the shear rate increases (thixotropy).
The thixotropy of an aqueous solution of HEC increases with higher viscosity products with higher molecular weight, and decreases with lower viscosity products. Low-viscosity products have very low thixotropy and exhibit characteristics similar to Newtonian fluids.

Both gelatin and HPMC capsules are durable if certain conditions are met. The shelf life for gelatin capsules is five years if the capsules are kept at the recommended storage temperature of 59°-77°Fahrenheit / 15°-25°Celsius, with a relative humidity between 35 and 65%. HPMC capsules also have a five-year shelf life, although they can tolerate greater heat and humidity. Here the recommended conditions are more forgiving: storage temperature of 59°-86°Fahrenheit / 15°-30°Celsius with a relative humidity between 35 and 70%.
Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose. With the chemical formula C2H6O2·C6H10O5, HEC has garnered significant attention in various industrial sectors for its unique properties, which include its ability to form gels and emulsions, retain moisture, and improve the texture of products. This cellulose derivative serves crucial functions across multiple applications, ranging from construction materials to food production.
Hydroxypropyl methylcellulose ( (Propylene glycol ether of methylcellulose) is a methylcellulose modified with a small amount of propylene glycol ether groups attached to the anhydroglucose of the cellulose. The dry product contains 19 to 30 per cent of methoxyl (-OCH3) groups and 3 to 12 per cent of hydroxypropyl (-OCH2CHOHCH3) groups. HPMC can be derived from tree fiber or cotton fiber.
2: How HPMC is made:
The cellulose ethers are manufactured by a reaction of purified cellulose with alkylating reagents (methyl chloride) in presence of a base, typically sodium hydroxide and an inert diluent. The addition of the base in combination with water activates the cellulose matrix by disrupting the crystalline structure and increasing the access for the alkylating agent and promotes the etherification reaction. This activated matrix is called alkali cellulose (Kirk-Othmer, 1993). During the manufacture of HPMC alkali cellulose reacts with methyl chloride to produce methyl cellulose and sodium chloride. Side reactions of the methyl chloride and sodium hydroxide produce methanol and dimethyl ether by-products. The methylcellulose is then further reacted with the staged addition of an alkylene oxide, which in the case of HPMC is propylene oxide (Kirk Othmer, 1993 Dow, 2002). After this reaction, MC and HPMC are purified in hot water, where they are insoluble. Drying and grinding completes the process.
3: Chemicals agents and reactions:
The chemical reactions of manufacturing HPMC summerize as following:
HEC is derived from cellulose, a natural polymer found in the cell walls of plants. The introduction of hydroxyethyl groups onto the cellulose backbone enhances its solubility in cold water, allowing it to dissolve easily without requiring heat. This property is particularly beneficial for applications where high temperatures might degrade other ingredients. The capacity of HEC to modify the viscosity of solutions is directly influenced by its concentration—this relationship is fundamental to its functionality in various applications.
The construction industry has also benefited from the unique properties of HPMC. It is commonly used in the formulation of cement-based dry-mix products, such as tile adhesives and joint compounds. HPMC improves workability, water retention, and adhesion of these materials, making application easier while ensuring durability and performance. Moreover, its water-retaining properties are critical, as they allow for better curing of cement, which ultimately enhances the strength of the final structure.
