5. Test the Seal Once installed, close the window and check for any gaps or drafts. If necessary, adjust the weatherstripping until a tight seal is achieved.

- Test for Air Leaks After installation, conduct a simple test by closing the door or window and checking for drafts. If you feel air coming through, you may need to adjust or add more weather stripping.

4. Cost-Effectiveness While the initial investment in an anti-fungal bath mat may be higher than that of a standard mat, the longevity and reduced frequency of replacement make them a cost-effective choice in the long run. Increased durability means that these mats won’t need to be replaced as often as traditional options, saving you both money and effort.

Anti-slip mesh is typically made from durable materials such as fiberglass, plastic, or metal, featuring a textured surface that provides additional friction. These meshes can be applied to various surfaces, including stairs, walkways, and ramps. Their primary function is to create a safer footing underfoot, significantly reducing the risk of slips and falls.

Die Pflege einer Holztreppenrandverkleidung erfordert regelmäßige Aufmerksamkeit, um die Schönheit des Holzes zu bewahren. Eine gelegentliche Reinigung mit einem feuchten Tuch und die Verwendung einer geeigneten Holzpflege können das Holz vor dem Vergrauen schützen. Je nach Nutzungshäufigkeit kann auch eine Auffrischung des Lacks oder der Ölbehandlung notwendig sein, um die Oberfläche zu schützen und den Glanz zu bewahren.

One of the main challenges that manufacturers face when it comes to buff percentage is ensuring consistency. Variations in the level of coating on titanium dioxide particles can lead to differences in color, opacity, and other properties in the final product. This can be especially problematic in industries such as paint and coatings, where consistency is critical for achieving the desired results.

The most common foods containing titanium dioxide are chewing gum, candies, pastries, chocolates, coffee creamers, and cake decorations (1Trusted Source, 3Trusted Source).

One of the key challenges facing TiO2 industry suppliers is the fluctuation of raw material prices. The production of TiO2 requires raw materials such as ilmenite or rutile, which are subject to market price volatility. Suppliers must carefully monitor these fluctuations and adjust their production processes accordingly to ensure profitability.

Exposure routes are the pathways that allow ingredients to enter our bodies. Primary exposure routes include: 

Titanium dioxide has also been classified as a possible human carcinogen by the International Agency for Research on Cancer, which has caused concern about its use in food products. This classification, however, is currently based on limited evidence from animal studies that involved the inhalation of titanium dioxide particles that increased the risk of lung cancer.

In a study published in the journal Toxicology, researchers examined the effects of exposing human colon cancer cell line (HTC116) titanium dioxide food additives in vitro. “In the absence of cytotoxicity, E171 was accumulated in the cells after 24 hours of exposure, increasing granularity and reactive oxygen species, inducing alterations in the molecular pattern of nucleic acids and lipids, and causing nuclei enlargement, DNA damage and tubulin depolymerization,” the scientists wrote. Researchers removed the additive from the culture, then examined the results 48 hours later. They found, “The removal of E171 was unable to revert the alterations found after 24 h of exposure in colon cells. In conclusion, exposure to E171 causes alterations that cannot be reverted after 48 h if E171 is removed from colon cells.”

In terms of manufacturers, there are many companies that produce calcium carbonate and titanium dioxide. Some of the top manufacturers of calcium carbonate include Omya, Imerys, and Minerals Technologies. These companies have large mining operations and production facilities in regions where calcium carbonate is abundant.

Nowadays, the use of nanoparticles in pharmaceutical and cosmetic products has increased. In the last case, nano-sized components are used without proper characterization of their effects, leading to unwanted and dangerous consequences for the users [1,2].

Pigment grade titanium dioxide is produced at a much larger particle size than nano grade. It is used as a colourant to whiten and brighten product formulations. Nano grade titanium dioxide is manufactured into very fine (nano) particles and is transparent and colourless. It is commonly used in sunscreens to provide effective protection from potentially harmful UV rays.

In 2017, French researchers from the Institut National de la Recherche Agronomique (INRAE) were among the first to examine the effects of E171 nanoparticles on the body. They fed rats a dose of 10mg of E171 per kilogram of body weight per day, which was similar to human exposure in food. The research, which was published in Scientific Reports, showed that E171 was able to traverse the intestinal barrier, pass into the bloodstream, and reach other areas of the body in rats. Researchers also found a link between immune system disorders and the absorption of titanium dioxide nanoparticles.

We've used titanium dioxide safely for decades. However, recently its safety was called into question. 
 
At CRIS, we've explored the safety of titanium dioxide for nearly half a decade, including conducting double-blind research to test the safety of food-grade titanium dioxide (E171). Our study shows that when exposed to food-grade titanium dioxide in normal conditions, research animals did not experience adverse health outcomes.
 
It's important to emphasize that in a National Institutes of Health study, experimental animals were exposed to titanium dioxide in amounts as high as 5% of their diet for a lifetime and showed no evidence of adverse effects. 
 
A handful of studies greatly influenced the decisions made by the European Food Safety Authority (EFSA). Unfortunately, these studies did not consider that titanium dioxide exposure comes from food, not drinking water. Additionally, CRIS researchers could not reproduce the adverse outcomes identified by the studies through typical food ingestion. Regardless, the EFSA banned E171 as a food ingredient and for use in other capacities in the summer of 2022.
 
In 2022, the United States, United Kingdom, and Canada maintained that the scientific evidence supports that titanium dioxide (E171) is safe for humans to use and consume.
