pigment titanium dioxide supplier

For research published in Archives of Toxicology in 2020, scientists fed one group of mice a solution containing titanium dioxide for one month, and compared it to those that did not receive the additive. They found “the richness and evenness of gut microbiota were remarkably decreased and the gut microbial community compositions were significantly changed” in the titanium dioxide group when compared with the control group. The tests also revealed that the titanium dioxide exposure could cause locomotor dysfunction, or mobility issues “by elevating the excitement of enteric neurons, which might spread to the brain via gut-brain communication by vagal pathway.” The researchers concluded: “These findings provide valuable insights into the novel mechanism of TiO2NP-induced neurotoxicity. Understanding the microbiota-gut-brain axis will provide the foundation for potential therapeutic or prevention approaches against TiO2NP-induced gut and brain-related disorders.”

While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.

  • Hydroxypropyl methyl cellulose, commonly abbreviated as HPMC, is a versatile pharmaceutical excipient widely used in the formulation of various dosage forms. This semi-synthetic polymer is derived from naturally occurring cellulose, which is modified through the addition of methoxy and hydroxypropyl groups to improve its solubility and stability in water. The resulting compound possesses unique characteristics that make it an indispensable component in the manufacturing process of tablets, capsules, films, and even some types of suspensions and emulsions. One of the primary functions of HPMC is as a binder in the production of tablets. It provides cohesion between particles, ensuring that the tablet maintains its structure during compression and post-production handling. Moreover, HPMC can act as a release-controlling agent due to its ability to form a gel layer upon contact with aqueous fluids. This property allows for the sustained or controlled release of active pharmaceutical ingredients (APIs), which can optimize therapeutic efficacy by maintaining drug levels within the desired therapeutic window over an extended period. In addition to its role in solid dosage forms, HPMC also finds application in the preparation of film coatings. These coatings protect the core tablet or capsule from environmental factors such as moisture and light while improving the aesthetic appeal and patient acceptability of the medication. Furthermore, the use of HPMC in film coatings can facilitate the development of modified-release dosage forms, where the rate at which the API is released into the body is carefully managed to suit the treatment regimen.
