  • Data on chronic toxicity and carcinogenicity are available for microcrystalline cellulose (E 460), methyl cellulose (E 461) hydroxypropyl cellulose (E 463), HPMC (E 464) and sodium carboxymethyl cellulose (E 466). Some studies were unfit for evaluation due to methodological shortcomings. In the only relevant study, the dietary administration of even high doses of microcrystalline cellulose (E 460) (30%, 15,000 mg/kg bw) to rats for 72 weeks did not affect survival, feed efficiency or haematology. Apart from some dystrophic calcification in renal tubules, no other relevant lesions were noted and tumour incidence did not differ with that of controls. Several studies were conducted in rats with methyl cellulose (E 461) via feed or drinking water or by gavage at concentrations up to 5% (2,500 mg methyl cellulose/kg bw per day) and for up to 2 years. For all examined parameters, no adverse effects were reported and also the observed tumours did not differ in type and number in treated and control groups. In the only identified study, the daily dosing of male and female rats (0, 1,500, 3,000 or 6,000 mg hydroxypropyl cellulose/kg bw) via gavage for 6 months did not cause adverse effects (including carcinogenicity) apart from a decrease in body weight in high-dosed rats (statistically significant in females only). Apart from a decrease in body weights of high-dosed males, no other significant adverse findings were reported and there was no indication of a carcinogenic effect in rats of either sex dietary exposed to HPMC (E 464) up to 20% (10,000 mg/kg bw per day) for 1 year. Carboxy methylcellulose (E 466) was tested in mice and rats at dosages of 0, 10,000 or 100,000 mg/kg diet (equivalent to 0, 1,500 or 15,000 mg/kg bw per day for mice and to 0, 500 or 5,000 mg/kg bw per day for rats) for up to 104 weeks. Despite the increase in feed intake, a treatment related decrease in body weight was noted at the end of the treatment. Histological examination revealed no intestinal abnormality or evidence of the passage of the additive across the intestinal wall in either species and the tumour incidences were comparable among groups.

  • HPMC powder, in its dry form, is a white, odorless, and tasteless substance. Its solubility in water is one of its key features, allowing it to dissolve easily and form a clear, viscous solution. This property makes HPMC a preferred choice in the pharmaceutical industry as a binder, thickener, and disintegrant in tablet formulations. It ensures the uniform distribution of active ingredients and improves the overall stability of the formulation.
  • There are several key benefits to using HPMC in building coating adhesives
  • Once the polymerization is complete, the next phase is spray-drying. The liquid polymer dispersion is atomized into fine droplets and introduced into a hot air stream in a spray-drying tower. As the droplets come into contact with the hot air, the water evaporates rapidly, leaving behind solid polymer particles. The particle size and shape are critical factors that influence the redispersibility of the final product, and they are controlled by adjusting the spray-drying conditions such as the inlet and outlet temperatures, feed rate, and nozzle design The particle size and shape are critical factors that influence the redispersibility of the final product, and they are controlled by adjusting the spray-drying conditions such as the inlet and outlet temperatures, feed rate, and nozzle design The particle size and shape are critical factors that influence the redispersibility of the final product, and they are controlled by adjusting the spray-drying conditions such as the inlet and outlet temperatures, feed rate, and nozzle design The particle size and shape are critical factors that influence the redispersibility of the final product, and they are controlled by adjusting the spray-drying conditions such as the inlet and outlet temperatures, feed rate, and nozzle designredispersible polymer powder manufacturing process.

  • The hydrophilic nature of HPMC means that it can interact with water through hydrogen bonding. When HPMC is added to water, the polar hydroxyl groups on the polymer chain attract water molecules, causing the polymer to hydrate and swell. This process is further facilitated by the thermal motion of water molecules, which helps to separate the individual HPMC chains and promote their dissolution.
  • The selection of the appropriate HPMC viscosity grade is crucial for achieving optimal product performance and stability. For instance, using a lower viscosity grade than required may result in poor tablet hardness and disintegration time, leading to inadequate drug release. On the other hand, using a higher viscosity grade than necessary can cause issues with mixing and processing, resulting in uneven distribution of the active ingredient and reduced product quality. Therefore, it is imperative to carefully consider the intended use and desired characteristics of the final product when selecting an HPMC viscosity grade.
  • The gelation temperature of HPMCP refers to the temperature at which the polymer undergoes a phase transition, changing from a solid state to a gel-like consistency. This transition is crucial for controlling the release of drugs encapsulated within HPMCP-coated formulations. When exposed to body temperatures during digestion, the HPMCP coating begins to soften and eventually forms a gel layer. This layer acts as a barrier, preventing premature drug release in the stomach while allowing controlled release in the intestine.
