As soon as a product is labeled as vegetarian or vegan, consumers immediately get the impression that there’s something inherently good or natural about it, or that it’s somehow better for their health. However, the recent discussions about vegetarian meat substitutes have shown that this is not necessarily true. Such is the case for HPMC hard capsules. They’re vegan, made from cellulose fiber and therefore regarded as natural.

The applicant claims that the feed additive HPMC is specified to be manufactured to meet the specifications set for its use as a food additive. The main specifications as food and feed additive are: methoxyl groups ≥ 19 and ≤ 30%, hydroxypropoxyl groups ≥ 3 and ≤ 12%, loss on drying < 10%, sulfated ash < 1.5% (for products with viscosities of 50 mPa.s or above) or < 3% (for products with viscosities below 50 mPa.s). Five batches of the additive were analysed for some of the above specifications, resulting in: methoxyl groups (four batches) 23.5–29.2%, hydroxypropoxyl groups (four batches) 5.2–8.4%, loss on drying (one batch) 1.2% and sulfated ash (one batch) 0.6%. Only statements, without figures, of compliance with the specifications for some impurities (heavy metals, arsenic, solvents, microbial purity) were provided. Information on other impurities ((pesticides, dioxins, dioxin-like and non-dioxin-like polychlorinated biphenyls, mycotoxins, botanical impurities) was not provided.
General drug facts
HPMC (Hydroxypropyl methyl cellulose) is a water-soluble polymer made from cellulose modified with hydroxypropyl groups. It is used as a thickener, emulsifier and stabilizer in foods, pharmaceuticals and cosmetics. HPMC is produced by treating methyl cellulose with propylene oxide. The end result is a white, odorless and tasteless powder. Hydroxypropyl methyl cellulose is very similar to methyl cellulose, but it is more soluble in water and has a higher viscosity. HPMC has many uses, such as a thickener (to replace cornstarch), a stabilizer (to prevent ingredients from separating or settling), a binder (to hold ingredients together), or an emulsifier (to mix two substances that do not dissolve well into each other).
Answer: HPMC in the application of putty powder, thickening, water retention and construction of three roles. Thickening: Cellulose can be thickened to suspension, so that the solution to maintain uniform up and down the role of the same, anti-hanging. Water retention: Make putty powder dry slowly, assist ash calcium reaction under the action of water. Construction: cellulose has lubricating effect, can make putty powder has good construction property. HPMC does not participate in any chemical reactions, but only plays an auxiliary role. Putty powder and water, on the wall, is a chemical reaction, because of the formation of new substances, the putty powder on the wall off the wall, ground into powder and then use, will not work, because a new substance (calcium carbonate) has been formed. The main components of ash calcium powder are: Ca(OH)2, CaO and a small amount of CaCO3 mixture,
CaO+H2O=Ca(OH)2 - Ca(OH)2+CO2=CaCO3↓+H2O Ash calcium generates calcium carbonate under the action of CO2 in water and air, while HPMC only holds water to assist ash calcium to react better, and itself does not participate in any reaction.

HPMC VS HEC: DS
Hydroxypropyl helps increase the water solubility of HPMC, making it easier to incorporate into formulations and ensuring better bioavailability of the active ingredients. Methyl groups, on the other hand, affect the viscosity and film-forming properties of HPMC, which can control the texture and appearance of the final product.

hpmc for mortar. Its ability to hold water helps in the even distribution of moisture during the drying process, reducing shrinkage and minimizing stress points that could lead to crack formation. As a result, the mortar cures more uniformly and is less likely to develop fractures over time.
