Weatherstripping refers to the material used to seal gaps around doors and windows. Commonly made from rubber, foam, or felt, it is designed to fill spaces where air and moisture can seep in, making it vital for maintaining an effective thermal envelope. In commercial settings, where foot traffic is high and buildings are often larger and more complex, the need for robust and durable weatherstripping solutions becomes even more apparent.

2. Comfort Sealing drafts leads to a more comfortable living environment. Areas around windows and doors are common spots for drafts, often leading to cold spots in winter and overheating in summer. Weather stripping ensures a more stable indoor climate, making your living space more enjoyable.

Exterior wall drainage mats are specialized barriers designed to prevent water accumulation against a building's exterior walls. They are typically made from materials such as high-density polyethylene (HDPE) or similar polymers that are resistant to water and provide a durable solution for moisture management. These mats are installed during the construction phase, positioned between the building's structural wall and exterior cladding, such as brick, stone veneer, or siding.

Lithopone is a white pigment (PW5) co-precipitated from solutions of zinc and barium salts according to the following reaction: 

≥ 5 % of standard sample

In addition to quality, CAS 13463-67-7 also places a strong emphasis on sustainability. The factory is dedicated to reducing its environmental impact by implementing eco-friendly practices and technologies. From waste reduction to energy efficiency, CAS 13463-67-7 is constantly looking for ways to improve its sustainability and contribute to a greener future.

At the present JECFA meeting, the committee considered additional toxicological studies relevant to the safety assessment of the chemical that investigated its toxicokinetics, acute toxicity, short-term toxicity, long-term toxicity and carcinogenicity, genotoxicity, and reproductive and developmental toxicity, as well as special studies addressing its short-term initiation/promotion potential for colon cancer. The experts acknowledged that a large number of toxicological studies have been conducted using test materials, including nanoparticles, having size distributions and physico-chemical properties not comparable to real-world uses of titanium dioxide as a food additive. The studies on non-representative materials were evaluated by JECFA, but the committee concluded that such studies are not relevant to the safety assessment of the additive.

2. Barite calcination method A solution of barium sulfide is prepared. The sulfuric acid and zinc oxide are reacted, purified by adding potassium permanganate and zinc powder, and compressed to obtain a zinc sulfate solution. Then, the prepared barium sulfide solution is mixed and subjected to a metathesis reaction to obtain a mixture of zinc sulfide and barium sulfate, and then the precipitate is subjected to pressure filtration, calcination, wet grinding, drying, and pulverization to obtain a zinc white product.

JECFA previously assessed titanium dioxide at its 13^th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.

Nano-sized TiO₂ generally shows low or no acute toxicity in both invertebrates and vertebrates. However, exposure of Daphnia magna to 20 ppm TiO₂ for 8 consecutive days was found to cause 40 % mortality. Zhu et al. showed minimal toxicity to D. magna after 48 h exposure, while upon chronic exposure for 21 days, D. magna suffered severe growth retardation and mortality. A significant amount of nano-sized TiO₂ was found also accumulated in the body of the animals. Similar findings with coated nano-sized TiO₂ (T-Lite™ SF, T-Lite™ SF-S and T-Lite™ MAX; BASF SE) were reported by Wiench et al. Biochemical measurements showed that exposure to TiO₂ NPs induces significant concentration-dependent antioxidant enzyme activities in D. magna. Lee et al. showed that 7 and 20 nm-sized TiO₂ induced no genotoxic effect in D. magna and in the larva of the aquatic midge Chironomus riparius.

What Is Titanium Dioxide?

Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.” 

Like all our products and ingredients, the titanium dioxide we use meets the highest standards for quality and safety, respecting all applicable laws and regulations as well as meeting our own safety assessments. Our scientists continue to review the latest scientific data and is confident that the titanium dioxide used in our products is safe.

In 2023, the demand for titanium dioxide is expected to reach new heights. One of the main drivers of this growth is the cosmetics and personal care industry. Titanium dioxide is widely used in sunscreens, skin care products and cosmetics for its excellent UV protection properties and ability to provide a smooth surface. With growing awareness of the harmful effects of UV radiation, consumers are increasingly inclined to invest in products with sun protection. This trend is expected to drive the demand for titanium dioxide over the next few years.

In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”
