Studies of titanium dioxide as a food additive suggest health dangers
Additionally, the committee noted that the available data did not provide convincing evidence of genotoxicity for titanium dioxide as a food additive, but recognized the limitations in current methodologies with respect to the testing of poorly soluble particulate materials. Although there were uncertainties in the genotoxicity data, the experts took into account the fact that the additive was not carcinogenic in adequately conducted two-year studies in mice and rats at doses of up to 7,500 mg/kg BW per day for mice, and 2,500 mg/kg BW per day for rats, the highest doses tested. There was also no evidence of reproductive or developmental toxicity in studies in rats at doses up to 1,000 mg/kg BW per day, the highest doses tested.

Titanium dioxide is used in a wide range of food products and consumer goods – from candy to sunscreen and house paint. The U.S. Food and Drug Administration maintains that the regulated use of titanium dioxide, specifically as a color additive in food, is safe under some restrictions.
As a widely used substance with multiple applications, research is being carried out to improve the production process to reduce the levels of chemicals used and waste produced, and to recycle any by-products.
The mineral appears to have low skin penetration, but it is a greater concern when inhaled frequently over time.
North America
Titanium dioxide, or TiO2, sometimes referred to as E171, is an inorganic, solid substance used in a wide range of consumer goods including cosmetics, paint, plastic and food, according to the American Chemistry Council.
The company has a wide variety of products, mainly including rutile titanium dioxide R818, R838, R868, R878, covering profiles, also have anatase TiO2 A1. Soft plastics and masterbatches, flat coatings, high-gloss coatings, water-based coatings, oil-based coatings, rubber, powder coatings, papermaking and other special fields, its products have been known in the market for their excellent whiteness and brightness, good hiding power and tinting power, stable application performance, and stable product quality and supply capacity.
The rapid method of synthesis described here is readily scalable to the proportions required in cosmetics manufacture.
1. Introduction
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.
It's also added directly to food; mainly for coloring, but also as a thickener and to keep some powdered food, like confectioner's sugar, from clumping.
CSPI’s Chemical Cuisine is the web’s definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance. Besides titanium dioxide, the group recommends avoiding artificial sweeteners like aspartame, acesulfame potassium, and sucralose, as well as synthetic food dyes like Yellow 5 and Red 3. CSPI and others have recently asked the Food and Drug Administration to ban the latter dye in foods and ingested drugs because the FDA has already determined that it is a carcinogen unsafe for use in cosmetics.
The R996 grade titanium dioxide from Lomon is particularly well-suited for use in the paint industry due to its superior tinting strength and dispersibility. These properties allow paint manufacturers to achieve vibrant and consistent colors in their products, resulting in high-quality finishes for a variety of applications.

While Skittles don't include white in their line-up, Dr. Johnson-Arbor theorizes that titanium dioxide is used to help contain all the other beautiful colors.
Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).
It does not react with other ingredients in the food and does not impart any taste or odor It does not react with other ingredients in the food and does not impart any taste or odoranatase titanium dioxide food grade. This makes it a versatile additive that can be used in a wide variety of food products without affecting their quality or safety.
