The additives that received a “no safety concern” conclusion based on current estimated dietary exposure are as follows:

The major restraint to the global Lithopone market is the availability of numerous white pigment substitutes. It can be replaced by other inorganic white pigments such as Titanium Dioxide (TiO2) and Sachtolith. Among these substitutes, the introduction of TiO2 has reduced the commercial importance of Lithopone white pigment. Compared to other white pigments, TiO2 has high brightness and refractive index, which results in lower pigment loading. 

When used in an ultrafine-grade formulation, titanium dioxide becomes transparent to light, effectively making it an absorber of UV light. And because its particles are so small in this form, titanium dioxide creates a transparent barrier that absorbs UV light.

New Safety Rulings & Regulations

The raw material used in this method is FeSO4. In order to maintain the Fe3 + concentration in the reaction medium in a specific range, reducing agent iron sheet is added in the reaction process. Iron yellow crystal seed was added and air was introduced to synthesize iron yellow under certain pH conditions. The method mainly includes two steps: (1) firstly, FeSO4 · 7H2O is used as raw material, NaOH or NH3 · H2O is used as precipitant or pH regulator, and air is used as oxidant to prepare crystal seed; (2) Iron yellow is produced by two-step oxidation with crystal seed, FeSO4, iron sheet and air.

In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone. 

Developing new Lithopone formulations, one that enhances the properties of the existing Lithopone is anticipated to boost the demand for Lithopone white pigment during the forecast period. Reinforced Lithopone is one such development, wherein a copolymer is added to the polymerization reaction to yield Lithopone with an increased weather resistance and an anti-ultraviolet property. Moreover, development of nano-scale Lithopone is also anticipated to attract market interest during the forecast period.

Health Canada's Food Directorate recently completed a “state of the science” report on titanium dioxide (TiO₂) as a food additive. Food-grade TiO₂ is a white powder made up of small particles that has been permitted in Canada and internationally for many years as a food additive to whiten or brighten foods. Food-grade TiO₂ has long been considered safe in Canada and in other countries when eaten as part of the diet.

Finally, it's important to consider the global trends impacting the pigment industry as a whole. Environmental regulations, technological advancements, and sustainable practices are increasingly becoming part of the conversation. Suppliers that prioritize eco-friendly production methods or offer biodegradable alternatives may appeal to buyers willing to pay a higher price for sustainably sourced materials.

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.

In addition to quality and reliability, r 996 titanium dioxide suppliers also offer competitive pricing, ensuring that customers get value for their money. By sourcing products from these suppliers, businesses can save costs without compromising on the quality of the raw materials used in their production processes.

But a chemical’s safety when it’s used externally is not always the same as when it’s ingested. Different uses of the same ingredient may cause very different health outcomes.

Le Lithopone Alcalin est un pigment blanc formé par le mélange intime en précipitation simultanée de sulfure de zinc et de Sulfate de Baryum. Le lithopone dit normal renferme 29.5% de ZnS et 70.5% de BasSO4 et renferme un peu d'Oxyde de Zinc.

According to a 2011 study published in Radiology and Oncology, titanium dioxide may lead to some adverse effects in the body, including oxidative stress, inflammation, and changes in cell signaling pathways. Additionally, pure titanium dioxide can be notably harmful when inhaled.

While this ruling from the EU General Court doesn’t immediately change the regulations surrounding titanium dioxide, nor does it change the ban that went into place in 2022, it does put the ingredient back in the spotlight.
 
In the coming months, we will see how the ruling impacts the regulations around titanium dioxide (E171), and we’ll see if the European Food Safety Authority (EFSA) will take another look at the body of scientific evidence used to justify the current ban on E171 in foods and pharmaceuticals.

At present, the equipment and manufacturing process of domestic manufacturers of polyvinyl butyral are constantly getting closer to those abroad. For example, the wonderful use of polyvinyl butyral (PVB) has occurred in the printing industry and ceramic industry. Therefore, the domestic application of polyvinyl butyral (PVB) has an obvious upward trend in recent years.

For example, in the glass industry, it is because polyvinyl butyral (PVB) has good low-temperature impact strength, windability, light transmittance, light resistance, weather resistance, sound insulation, UV insulation and other properties, so that once the laminated glass is sealed together, the glass sandwich (i.e. laminated material) will appear as a whole and look like ordinary glass. For example, in the porcelain industry, polyvinyl butyral is made into a film and used for printing paper film of ceramic (or enamel) products. First, it reduces the original glue small paper Decal process, reduces the production cycle and production cost, and second, it makes its ceramic (or enamel) patterns bright in color and smooth in texture.

With the rapid development of science and technology in recent years, more and more industries have found the characteristics of polyvinyl butyral (PVB): high strength, high toughness, fatigue resistance, corrosion resistance and so on. Compared with traditional materials, polyvinyl butyral (PVB) is more and more widely used because of its larger development space and wider application fields!

Application field of polyvinyl butyral -- safety glass

The membrane made of polyvinyl butyral (PVB) is a special product used to manufacture safety glass and bulletproof glass. Safety glass is a special glass made of a layer of PVB diaphragm sandwiched between two layers of ordinary glass. It has good low-temperature impact strength, windability, light transmittance, light resistance, weather resistance, sound insulation, ultraviolet insulation and other properties. When subjected to strong external impact, PVB diaphragm can absorb impact energy, so that the glass will not break or prevent debris from hurting people. Moreover, the safety glass added with PVB diaphragm has the characteristics of high transparency, water resistance and aging resistance, and can be used in the environment of - 60 ℃. In addition, it can also be used as transparent material to replace plexiglass.
