- In the textile industry, vinyl acetate ethylene redispersible powder is often used as a sizing agent for warp yarns in textile production
vinyl acetate ethylene redispersible powder. This helps to improve the strength and abrasion resistance of the yarns, making them more durable and suitable for weaving and other textile processes. The powder also enhances the washability and overall quality of the finished textiles, ensuring that they maintain their appearance and performance over time.

Hydroxypropyl Methylcellulose (HPMC) plays a crucial role in pharmaceutical formulations due to its diverse range of benefits. One of its primary uses is as a key component in controlled-release drug delivery systems. HPMC’s ability to modify drug release rates enables pharmaceutical companies to develop medications that provide sustained therapeutic effects, leading to improved patient compliance and reduced dosing frequency. Moreover, HPMC is utilized as a binder in tablet formulations, contributing to the mechanical strength and disintegration properties of tablets, thereby ensuring consistent drug release and bioavailability. Its biocompatibility and inert nature make it suitable for a wide range of drug formulations, including oral, topical, and ophthalmic products, underscoring its versatility in pharmaceutical applications.
Da HPMC ein Abkömmling der natürlichen Cellulose ist, ist HPMC vegan. Somit können Menschen, die sich vegan oder vegetarisch ernähren oder aufgrund ihrer Religion auf Gelatine verzichten, bedenkenlos zu HPMC-Kapseln greifen.
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.
