Titanium dioxide is an insoluble mineral, meaning it cannot dissolve in water. Known for its bright, white pigment, manufacturers use titanium dioxide in many different capacities, including in cosmetics, foods, and drugs.

Other research suggests that E171 could cause harm; however, those research processes did not consider how people are typically exposed to E171. Research that adds E171 to drinking water, utilizes direct injections, or gives research animals E171 through a feeding apparatus is not replicating typical human exposure. 

Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide is much more stable and can provide better sun protection than non-micronized titanium dioxide.

As an professional Lithopone factory, Jinan Hongquan Titanium Industry Co., Ltd is located in Jinan, a beautiful spring city. The company’s scientific research personnel sincerely cooperate with well-known domestic universities and various titanium dioxide production enterprises to study and produce active Lithopone with great concentration. Some of its products have been widely used in chemical, textile, paper, plastic, paint and other production fields.

Macromolecular oxidation was detected in proteins by the colorimetric measurement of Advanced Oxidation Protein Products (AOPP) and in lipids by the colorimetric quantification of malondialdehyde (MDA). Standard curves were run with chloramine-T and 1,1,3,3 tetraethoxypropane (TEP) for AOPP and MDA methods, respectively [29], [30], [31]. Values were normalized to initial protein content in samples, measured with Bradford reagent [32]. The standard deviation of at least six measures was calculated and p-value < 0.05 were considered significant.

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.

One of the main uses of TiO2 powder is as a pigment in paints and coatings. It is valued for its excellent opacity, brightness, and UV resistance, making it ideal for use in exterior paints, industrial coatings, and automotive finishes. TiO2 powder suppliers work closely with paint manufacturers to supply them with the right grade and quantity of TiO2 powder to meet their specific requirements.

The ingredient in question? Titanium dioxide.

1. Purity The purity of barium sulphate is essential, especially in applications such as pharmaceuticals. Suppliers should provide certifications stating the purity levels and any presence of impurities or contaminants.

Stability and darkening[edit]

No acute effects of nano-sized TiO₂ were observed in Danio rerio (zebrafish) embryos. Exposure of rainbow trout to TiO₂ NPs triggered lipid peroxidation, influence on the respiratory tract, disturbance in the metabolism of Cu and Zn, induction of intestinal erosion  and accumulation in kidney tissue. Linhua et al. exposed juvenile carp to 100 and 200 mg/ml of particles and TiO₂ observed no mortality. However, the fish suffered from oxidative stress and pathological changes in gill and liver. In the infaunal species Arenicola marina, exposure to TiO₂ NPs in sediment caused sub-lethal effects including decrease in casting rate and increase in cellular and DNA damage. Aggregated particles were visible in the lumen of the gut, but no uptake through the gut or the skin was observed.
