round weather stripping

In our quest for a safe and aesthetically pleasing bathroom environment, the bath mat plays a crucial role. Among the myriad designs available, the duck-themed non-slip bath mat stands out not only for its whimsical charm but also for its practical functionality. A non-slip bath mat is an essential accessory that enhances safety while adding a touch of personality to your bathroom decor.

In terms of aesthetics, silicone door strips come in a variety of colors and finishes, ensuring they can blend seamlessly with any interior design. Homeowners no longer need to sacrifice style for practicality; these strips can complement the overall décor of a room, adding both functionality and visual appeal.

ノンスリップトイレ床材は、その名の通り、滑りにくい特性を持っています。特にトイレは湿気が多く、床が滑りやすい環境です。水や掃除用の薬品が床にこぼれた場合、滑って転倒するリスクが高まります。ノンスリップ床材は、こうしたリスクを軽減するために設計されています。

Applications in Furniture and Cabinetry

Um “kerf style door sweep” (ou vedação de porta tipo kerf) é um elemento essencial para manter a eficiência energética e o conforto em nossos lares. Este tipo de vedação é projetado para ser instalado em portas que possuem uma ranhura (ou kerf) na parte inferior. Este design engenhoso permite que o varão de vedação se encaixe perfeitamente na porta, criando uma barreira eficaz contra correntes de ar, poeira, insetos e umidade.

The compound in the Asia Pacific market experienced a mixed trends throughout the fourth quarter of 2021. These market attitudes were mostly related to lower operational loads at Chinese domestic manufacturing plants.

3. What is EFSA saying in its 2021 opinion on the safety of titanium dioxide as a food additive?

What is an exposure route? 

Lithopone was developed in the 1870s as a substitute for lead carbonate (lead white), to overcome its drawbacks of toxicity and poor weathering resistance. Within a few years, titanium dioxide displaced lithopone to become the white pigment (PW6) par excellence in the industry and the world’s best-selling inorganic pigment. However, titanium is a product whose price is subject to large price variations due to product availability. These price increases affect the competitiveness of finished products, and so the search for an alternative to titanium dioxide has generated a variety of possibilities to optimise its use. 

Genotoxicity Assessment 

The titanium dioxide market fluctuated in the first two quarters of 2023. These pricing patterns resulted from poor demand and reduced intakes from the downstream industries. Amid the slow demand, the manufacturers were forced to reduce their outputs. With rising inflation rates, production cuts gradually increased. Given the economic downturn, the labor strikes further affected the market dynamics, thereby exerting pressure on the pricing fundamentals.

An inorganic chemical, titanium dioxide is used as a dye to help products achieve a certain appearance, including whitening a product. Some experts and publications have described it as being akin to a paint primer that's used before the color is added to food in order to give products a uniform shine. Its presence is common in many items beyond Skittles including coffee creamers, cake mixes, and chewing gum. It's also used for pigment and in cosmetics manufacturing.

Titanium dioxide can form several different shapes, which have different properties. Some shapes can be converted to nanomaterials. Micronized TiO2 (also called “nano” or “nanoparticles”) was introduced in the early 1990s.Nanotechnology and micronization both refer to the practice of creating very small particles sizes of a given material. “Nanoparticles” usually refers to particles smaller than 100 nanometers; a nanometer is 1/1 billionth of a meter. At these small sizes, and at low concentrations, titanium dioxide appears transparent, allowing for effective sunscreens that do not appear white.

Hiding power

In an early study Jani et al. administred rutile TiO₂ (500 nm) as a 0.1 ml of 2.5 % w/v suspension (12.5 mg/kg BW) to female Sprague Dawley rats, by oral gavage daily for 10 days and detected presence of particles in all the major gut associated lymphoid tissue as well as in distant organs such as the liver, spleen, lung and peritoneal tissue, but not in heart and kidney. The distribution and toxicity of nano- (25 nm, 80 nm) and submicron-sized (155 nm) TiO₂ particles were evaluated in mice administered a large, single, oral dosing (5 g/kg BW) by gavage. In the animals that were sacrificed two weeks later, ICP-MS analysis showed that the particles were retained mainly in liver, spleen, kidney, and lung tissues, indicating that they can be transported to other tissues and organs after uptake by the gastrointestinal tract. Interestingly, although an extremely high dose was administrated, no acute toxicity was observed. In groups exposed to 80 nm and 155 nm particles, histopathological changes were observed in the liver, kidney and in the brain. The biochemical serum parameters also indicated liver, kidney and cardiovascular damage and were higher in mice treated with nano-sized (25 or 80 nm) TiO₂ compared to submicron-sized (155 nm) TiO₂. However, the main weaknesses of this study are the use of extremely high single dose and insufficient characterisation of the particles.

Titanium dioxide is used a food colour (E171) and, as with all food colours, its technological function is to make food more visually appealing, to give colour to food that would otherwise be colourless, or to restore the original appearance of food. Titanium dioxide is also present in cosmetics, paints, and medicines.
