In May 2021, the European Food Safety Authority (EFSA) published an opinion that stated that titanium dioxide can no longer be considered safe when used as a food additive.

Despite its many advantages, TiO2 production is not without its challenges

In food, titanium dioxide is often used as an artificial color additive. Tasha Stoiber, senior scientist at the consumer health nonprofit Environmental Working Group, says titanium dioxide can generally be thought of as a paint primer – it often goes on a hard-shelled candy like Skittles before the color is added to give it a uniform shine.

Background and overview

Globally, Iron Oxide is the second largest inorganic pigment after Titanium Dioxide and the first largest color inorganic pigment. Iron oxide pigments mainly include iron oxide red, yellow, black and brown with iron oxide as the basic material. Iron oxide yellow, also known as hydroxyl iron oxide (FeOOH), will be dehydrated and decomposed into red at about 177 ℃, so the application of ordinary iron yellow pigment in high-temperature occasions such as plastic processing and baking coatings is limited. Iron oxide yellow pigment can improve its temperature resistance through surface coating, so as to expand the application field of iron oxide yellow pigment.

The chemical formula of iron oxide yellow (also known as hydroxyl iron) is α- Fe2O3 · H2O or α- FeOOH, with needle like structure and yellow powder, is a kind of particle size less than 0.1 μ m. Iron series pigment with good dispersibility in transparent medium has strong coloring power, high covering power, insoluble in alkali and slightly soluble in ACID. Synthetic iron oxide yellow has the characteristics of light resistance, good dispersion, non-toxic, tasteless and difficult to be absorbed by human body. It is widely used in coatings, plastics, ink and pharmaceutical industry.

Physical and chemical properties and structure

1. Iron oxide yellow pigment has acid and alkali resistance, resistance to general weak and dilute acids, and is very stable in alkaline solution of any concentration.

2. Iron oxide yellow pigment has certain light resistance, heat resistance and weather resistance. Its coating color is durable and can keep the coating from being damaged in light. Iron oxide yellow pigment is stable in a certain temperature range, but beyond the limit temperature, its color begins to change, and the degree of change is more significant with the increase of temperature. Iron oxide yellow pigment is not affected by cold, heat, dry and wet weather conditions.

3. Iron oxide yellow pigment is very stable in any ambient atmosphere (such as gases containing H 2S, Co, so 2, HCl, no, etc.). And resistant to pollution, water, oil and solvent penetration, insoluble in water, mineral oil or vegetable oil.

4. Iron oxide yellow pigment has strong coloring power and high hiding power. With the decrease of pigment particle size, its coloring power is stronger.

application

Nano iron oxide yellow has the characteristics of acid resistance, alkali resistance, non toxicity and low price. It is widely used in coatings, plastics and rubber. The particle size of nano iron yellow is less than 100 nm, which makes it have some unique characteristics. When light shines on its surface, transmission and diffraction will occur, showing transparent yellow, and can strongly absorb ultraviolet rays, Therefore, it can be used as a functional pigment for the surface paint of high-grade cars, precision instruments, bicycles, motorcycles, cosmetics, food, drugs and other coloring additives.

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.”

History

In conclusion, when sourcing anatase titanium dioxide pigment, it is essential to partner with a reputable supplier that offers competitive prices, high-quality pigment, reliability, and superior customer service. By taking the time to evaluate these factors, you can find a supplier that meets your needs and helps you achieve success in your industry.

Studies suggest that people are more likely to buy and eat foods that are brighter or more vibrant in color. And titanium dioxide is one way to make that happen. You can find it in food products like candy, coffee creamer, baking and cake decorations, and white sauces.

In addition to sunscreen, titanium IV oxide is also used in the production of paints. Titanium dioxide is a popular pigment in the paint industry because of its brightness and opacity. It provides excellent coverage and durability, making it an ideal choice for exterior and interior paints. Titanium dioxide is often used in white paints, but it can also be used to create a wide range of colors by mixing it with other pigments.

2. Cosmetics With its UV-filtering properties, anatase TiO2 is a popular ingredient in sunscreens and cosmetic formulations. Its ability to scatter UV radiation effectively protects the skin from harmful sun exposure, contributing to the increasing popularity of natural and mineral makeup products.

The paint and coating sector heavily relies on micro TiO2 for its excellent hiding power and durability. It improves the color retention and weather resistance of coatings, extending their lifespan and maintaining their aesthetic appeal.

TiO₂ particles of the right size scatter visible light, having wavelength λ ≈ 380 - 700 nm, effectively because TiO₂ has a high refractive index

After classification, the lithopone powder is packaged in airtight containers to prevent exposure to moisture and other contaminants

Lyophilized vitamins@P25TiO₂NPs were obtained through the described methods with excellent reproducibility and yield: over 99% of initial P25TiO₂NPs were functionalized.

There are many uses of titanium dioxide that we don't know about because they were made exempt from being on the package in 1977, said Faber, who added that nothing much has changed since – other than the FDA approving some other uses of the color additive, such as expanding the use of mica-based pearlescent pigments (prepared from titanium dioxide) as color additives in distilled spirits over recent years.

One of the key advantages of Lithopone 28-30% is its low toxicity and non-carcinogenic nature

lithopone 28-30% b301 b311 manufacturer. This makes it an environmentally friendly alternative to other pigments that may pose health risks to humans and wildlife. As a result, manufacturers are increasingly turning to Lithopone 28-30% as they strive to reduce their ecological footprint and comply with strict environmental regulations.

Furthermore, titanium dioxide has been shown to possess antioxidant properties

In conclusion, China's Tio2 pigment industry plays a pivotal role in the global market, not just in terms of volume but also in setting trends and influencing pricing strategies. As the world continues to grapple with economic and environmental challenges, China's ability to balance growth with sustainability will be a key factor in determining the future trajectory of the Tio2 pigment industry.

Lithopone has therefore traditionally been used in stoppers and putties, jointing compounds and sealing compounds, primers and undercoats and in road-marking paints.

High Opacity: Lithopone powder offers excellent hiding power, allowing for the creation of opaque and vibrant colors in paints, coatings, and plastics.

One of the key considerations when using titanium dioxide in food products is its particle size. The FDA has set limits on the particle size of titanium dioxide that can be used in food products, as smaller particles may pose a greater health risk. It is important to ensure that the titanium dioxide purchased meets these particle size standards to ensure the safety of the product.

One of the main uses of wholesale colloidal silicon dioxide is as a thickening and anti-caking agent in food and pharmaceuticals. It is commonly added to powdered substances to prevent clumping and improve flowability. In this application, colloidal silicon dioxide helps to maintain product quality and extend shelf life.
