- One of the most common uses of hydroxypropyl methylcellulose is in the construction industry. HPMC is commonly used as a thickener, binder, and stabilizer in cement-based materials such as mortars, plasters, and tile adhesives. It improves workability, water retention, and adhesion, making it an essential ingredient in many construction applications. Additionally, hydroxypropyl methylcellulose can be found in gypsum products, self-leveling compounds, and exterior insulation finishing systems.
- 2. Cosmetics HEC is widely used in cosmetics as a thickener, emulsifier, and film former. It provides moisturization, improves the feel and texture of cosmetic products, and helps to stabilize emulsions.
Cellulose wird in heißer Natronlauge gequollen und bei 50 bis 80 °C mit Propylenoxid und hohem Methylchlorid-Druck umgesetzt; Letzteres reagiert erst bei hoher Temperatur. Typische Nebenprodukte von Polykondensationen und Hydrolyse des Propylenoxids sind Propylenglycol, Di- und Tripropylenglykol sowie neben Methanol auch deren Methylether (z. B. Methoxypropanol, Dipropylenglycolmonomethylether usw.). Zur Isolierung werden zuerst alle bis 110 °C flüchtigen Stoffe abdestilliert und anschließend mit heißem Wasser alle Glycole und Salze ausgewaschen, der Feststoff getrocknet und zum Pulver vermahlen. Für den Lebensmittel- und Pharmabereich ist die Herstellung unter GMP-Bedingungen vorgeschrieben.


use of hpmc. HPMC can also be used as a water retention agent in plaster and stucco, helping to improve the consistency and workability of these materials.

Answer: HPMC viscosity is inversely proportional to temperature, meaning that viscosity increases as temperature decreases. When we refer to the viscosity of a product, it typically indicates the measurement of its 2% aqueous solution at a temperature of 20 degrees Celsius.
