Most of them are from construction and detergent product production field. We investigated the market and compared the quality from the market, and found our goal and made our plan for the next year. To serve better to our buyers.
The etherification of cellulose disrupts the hydrogen bonding and the resulting compounds are not ionised and more water soluble. The EFSA ANS Panel (2018) concluded that modified celluloses including ethyl and methyl, hydroxypropyl celluloses, would not be absorbed intact and not fermented in the gastrointestinal tract of animals (rat) or humans; they are excreted essentially unchanged mainly via the faeces (more than 90% of the administrated doses), while only minor amounts of metabolites and derived-products are excreted via urine or expired air (as 14CO2) and there is no indication for accumulation in the body.
- At its core, HPMC's chemical structure consists of a linear chain of glucose units connected by β-1,4-glycosidic bonds. These glucose units are derived from cellulose, a polysaccharide composed of hundreds to thousands of glucose monomers. The modification involves the substitution of hydroxyl groups on the cellulose backbone with methyl and hydroxypropyl groups, which significantly alters its physical and chemical characteristics.
- In the pharmaceutical industry, hydroxyethylcellulose is commonly used as a binder and film-forming agent in tablets and capsules. It helps to hold the ingredients together and ensures that the medication is released in a controlled and effective manner. Its ability to dissolve in water also makes it a preferred ingredient in liquid medications and suspensions.

Besonderheiten: Wässrige HPMC-Gele neigen dazu, bei der Erwärmung bei einer bestimmten Temperatur sehr schnell ihre Viskosität zu erhöhen. Diese Temperatur wird häufig als Gelpunkt bezeichnet, was in diesem Fall jedoch nicht völlig korrekt ist. Dieser Verfestigungsprozess ist reversibel, das heißt, sobald die Temperatur genügend gefallen ist, wird auch das Gel wieder flüssiger. Diesen Effekt macht man sich z. B. in der Lebensmitteltechnologie zunutze: Bratlingen wird HPMC zugesetzt, damit sie beim Braten (hohe Temperatur) fest, beim Verzehr (niedrigere Temperatur) jedoch wieder zart sind.
