Answer: The powder loss of putty powder is mainly related to the quality of hydrated lime (calcium hydroxide) and has little to do with HPMC. A low calcium content in hydrated lime and an inappropriate ratio of CaO to Ca(OH)2 can both cause powder loss. If there is some relation to HPMC, it would be that poor water retention of HPMC can also cause powder loss. For specific reasons, please refer to question 9.
Answer: HPMC produced through solvent methods uses solvents such as toluene and isopropanol. If the washing process is not thorough, there may be some residual odor.
- The percentage of HPMC in a formulation can significantly influence the drug delivery system
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.
- In the realm of pharmaceutical manufacturing, the role of Hydroxypropyl Methylcellulose (HPMC) cannot be overstated. This versatile polymer serves as a critical component in a range of formulations, from tablets to capsules and even topical applications. Its popularity stems from its ability to act as a binder, thickener, and disintegrant, among other functions.

In ruminants, cellulose is first hydrolysed by ruminal microorganisms into cellobiose, then is fermented to pyruvate and finally volatile fatty acids. The changes of forage to concentrate ratios in the diet significantly affect the number and type of rumen microorganisms and then affect the end products of fermentation. Moreover, the extent of cellulose digestion is a compromise between the rate of hydrolysis and the retention time in the rumen related to the particle size of the forage. The intrinsic digestibility of cellulose depends on the origin and treatment of the forage. As far as cellulose is associated to lignin, hemicelluloses and cutin in natural forages, a wide range of digestibility is observed (30 to 90%). Crystallinity of cellulose decreases the rate but not the extent of digestibility that may reach 80% (Van Soest, 1994).

HEC's high viscosity and pH stability might be preferred in certain formulations, while HPMC's improved solubility and enzyme resistance could be more critical in others. Both these hydrocolloids demonstrate the potential of science to tailor materials to meet specific needs, highlighting their importance in modern industrial processes.
