In another study, Jenni et al. stained MHEC with a fluorescent dye and visualized and quantified the migration of MHEC through the capillaries of mortars. They found that MHEC accumulates at system interfaces exhibiting a reduced porosity. From this, they conclude that the cellulose ethers can migrate through the pore system and are therefore not or only partly adsorbed on cement particles under wet conditions [18]. In a later publication from this group they state that the dissolved CE is transported downwards through the capillary pores, but accumulates at the contact layer and substrate surface, which act as micro-filters [19].

Cellulose powder, often referred to as microcrystalline cellulose (MCC), is produced through controlled acid hydrolysis of raw materials like wood pulp or cotton lint. The process breaks down the amorphous regions of cellulose, leaving behind a highly crystalline, free-flowing powder. The end result is a substance with high purity, excellent flowability, and good compressibility, making it ideal for pharmaceuticals, food additives, and cosmetics.

  • One of the most common uses of chemic HPMC is in the construction industry, where it is used as a key ingredient in construction materials such as cement and mortar. Chemic HPMC serves as a thickening agent, enhancing the workability and consistency of these materials. It also improves adhesion and water retention, making the final product more durable and resistant to cracking.
  • In the pharmaceutical sector, HPMC with a viscosity of 200,000 cP is often employed as a binder or a release-controlling polymer in tablets. This high viscosity ensures that the medication is released slowly into the body, maintaining consistent blood levels of the active ingredient over an extended period. This can significantly improve patient compliance by reducing the frequency of dosing.
