  • There are data for microcrystalline cellulose (E 460), methyl cellulose (E 461), hydroxypropyl cellulose (E 463) and sodium carboxymethyl cellulose (E 466), which were tested in mice, rats, hamsters and/or rabbits with oral dosing or via gavage. As regards microcrystalline cellulose (E 460) studies have been conducted in rats (dietary exposure) with a mixture including guar gum or sodium carboxymethylcellulose (E 466) (15% in either case). The NOAEL for both maternal and developmental toxicity were the highest experimental dosages, i.e. 4,500 mg/kg bw (for mixture with guar gum) and 4,600 mg/kg bw (for mixture with sodium carboxymethyl cellulose). Methyl cellulose (E 461) was examined in mice, rats, hamsters and rabbits. In two different studies, pregnant mice were exposed via gavage (vehicle corn oil) to a dose range of 16-1,600 mg methyl cellulose (E 461)/kg bw per day from day 6 to 15 of gestation, followed by a caesarean section at day 17 of gestation. In the first study, maternal toxicity (increase in mortality and reduced pregnancy rate in the survivors) as well as retarded ossification in fetuses were noticed at the highest tested level, pointing to a NOAEL of 345 mg methyl cellulose (E 461) mg/kg bw per day (the last but one highest dosage) in mice. In the second study, no maternal toxicity and fetal abnormalities were observed in mice exposed up to 700 mg methyl cellulose (E 461) mg/kg bw per day. Rat studies (n = 2) were performed in pregnant dams exposed via gavage (vehicle corn oil) to a dose range of 16-1,320 mg methyl cellulose (E 461) mg/kg bw per day from day 6 to 15 of gestation followed by a caesarean section at day 20. In the first study (0, 13, 51, 285 or 1,320 mg methyl cellulose (E 461)/kg bw per day) the highest tested dosage resulted in no maternal toxicity but also in increased incidence of extra centres of ossification in vertebrae of fetuses from high dose dams; in a second rat study, the incidence of such alteration slightly increased in fetuses from the highest dosed group (1,200 mg methyl cellulose (E 461)/kg bw per day). Based on the above results, a NOAEL of 285 mg methyl cellulose (E 461) mg/kg bw per day could be identified in rats. No maternal or fetal toxicity was detected in Golden hamsters exposed via gavage (vehicle corn oil) up to 1,000 mg methyl cellulose (E 461) mg/kg bw per day from day 6 to 10 of gestation followed by a caesarean section at day 20. The study on rabbits was discarded due to poor experimental design. The only relevant developmental toxicity study with hydroxypropyl cellulose (E 463) (dissolved in 1% gum arabic solution) was performed in pregnant rats exposed via gavage from day 7 to 17 of gestation to 0, 200, 1,000 or 5,000 mg/kg bw test item and some of them subjected to caesarean sections at day 20. No treatment-related adverse effects were detected in dams or in the examined fetuses. A number of dams were allowed to deliver and no clinical, behavioural or morphological changes were observed in the examined pups. Their reproductive ability was seemingly not affected and no abnormalities were found in the F1-derived fetuses. The in utero exposure to the highest dose (5,000 mg/kg bw per day) may be considered as the NOAEL of methyl cellulose (E 461) for this study. No mortality, and no adverse effects were observed on implantation or on fetal survival in pregnant mice or rats dosed via gavage with up to 1,600 mg sodium carboxymethyl cellulose (E 466)/kg bw per day.

  • The solubility of HPMC has significant implications in various industries. In pharmaceuticals, it serves as a binder, coating agent, and controlled-release matrix in tablets. In construction, it is used as a thickener, adhesive, and water retention agent in mortar and plasters. In the food industry, it acts as a stabilizer and emulsifier, while in cosmetics, it finds use as a film-forming agent.
  • - Quantity Determine the required amount, keeping in mind potential future needs and storage capabilities.
  • One of the key advantages of HPMC is its biocompatibility and safety for human use. It is non-toxic, hypoallergenic, and environmentally friendly, making it a preferred choice for many industries. Its inert nature ensures that it does not react with other ingredients or cause adverse effects on the end-users.
  • In terms of usage, the correct dosage and concentration of HPMC must be strictly followed
  • Cellulose, the primary structural component of plant cell walls, is the most abundant organic polymer on Earth. Hydroxyethylation, the process by which HEC is derived, enhances the solubility of cellulose in water, making it suitable for applications where pure cellulose would be insoluble. The degree of substitution, or the percentage of cellulose's hydroxyl groups replaced by hydroxyethyl groups, determines the properties of the final product. Higher substitution rates lead to increased solubility and viscosity.
  • When purchasing HEC, consider the following factors
  • Cellulose ether HPMC, also known as hydroxypropyl methylcellulose, is a versatile and essential ingredient。,,。
  • HPMC is a semi-synthetic polymer derived from cellulose. It consists of a glucose unit backbone with methyl and hydroxypropyl groups attached to it. This combination of substituents gives HPMC its water-soluble nature and thickening ability. On the other hand, HEC is also a cellulose derivative but with hydroxyethyl groups instead of hydroxypropyl groups. This subtle difference in chemical structure results in distinct physical and chemical properties between the two polymers.
  • In the realm of organic solvents, HPMC's solubility largely depends on the nature of the solvent, its molecular weight, degree of substitution, and temperature. Generally, HPMC exhibits good solubility in polar organic solvents such as methanol, ethanol, and acetone. It can also dissolve in dichloromethane, albeit to a lesser extent due to its less polar nature. However, it is important to note that HPMC is generally insoluble in non-polar organic solvents like hexanes or diethyl ether.
  • Application: Hydroxypropyl methylcellulose can be used in coatings, ceramics, printing inks, plastics. HPMC has construction grade, food grade, and pharmaceutical grade according to the application. The construction industry is the most widely used application for MELACOLL hydroxypropyl methylcellulose.

  • The HS code for HPMC is 3912.39.00, which falls under the category of cellulose and its chemical derivatives. This code is used by customs officials and trade organizations to identify and regulate the international trade of HPMC products. It is important for businesses that deal with HPMC to be aware of this code and ensure that they comply with all regulations related to the import and export of this material.

This versatile polymer is widely used as a thickening agent, stabilizer, and emulsifier in food, pharmaceuticals, and personal care products. In this article, we will discuss the various applications of HPMC in different industries.
  • The flooring industry also benefits from this technology. Redispersible polymer powders are often used in self-leveling floor compounds, ensuring a smooth, even surface with enhanced mechanical properties. They also contribute to the improved bonding of floor coverings, reducing the risk of delamination.
  • The selection of the right bonding agent is a critical decision in construction. Factors such as the type of masonry, environmental conditions, and expected load-bearing capacity must all be taken into consideration. Incorrect choice or application can lead to weak bonds, increased porosity, and ultimately, reduced lifespan of the structure.
