Lithopone’s historical significance is further accentuated by the advancements and modifications that followed its inception. The 1874 patent by J.B. Orr, for instance, ushered in a new white pigment—Orr’s Zinc White. This innovation was attained by co-precipitating zinc sulfate and barium sulfide, followed by a calcination process. Further refinements marked the subsequent decades, the most notable being the enhancement of lightfastness achieved in the 1920s by introducing small amounts of cobalt salts before calcination.

There are two primary forms of titanium dioxide commercially available: anatase and rutile. The rutile form is typically used in sunscreens due to its superior ability to handle UV rays and stability in the presence of UV light. The anatase form is typically used in other types of products, such as paint. Another plus of the rutile form is that its UVA protection extends past 400 nanometers, which is the upper limit of UVA.

Because the seller's inventory is small, the manufacturer has no willingness to reduce the price of sales, and the demand for new orders in the market is relatively large.Trend: The load of titanium dioxide enterprises is stable, the willingness to ship at low prices is not strong, and the downstream buyers still have inventory digestion, and the intention to supplement orders in the short term is limited. It is expected that the titanium dioxide market today just needs to stabilize the price, and the market trading atmosphere is more general.

Titanium dioxide has similar uses in non-food products. It is used in sunscreen as effective protection against UVA/UVB rays from the sun, which creates a physical barrier between the sun’s rays and the skin. It’s also used to whiten paint, paper, plastic, ink, rubber, and cosmetics.

Introduction

But what is titanium dioxide, exactly? Here's what you need to know about this popular food additive — including what products it's used in and whether it's safe to consume.

While loose titanium dioxide presents a problem, titanium dioxide within sunscreen formulations presents a much safer option than conventional sunscreen chemicals like oxybenzone and octinoxate. However, titanium dioxide may become dangerous when it is nanoparticle size. Generally, nanoparticles can be 1000 times smaller than the width of a human hair. Despite nanoparticles becoming increasingly common across industries, they have not been properly assessed for human or environmental health effects, nor are they adequately regulated. Researchers don’t quite understand the impacts nanoparticles could have on human health and the environment. However, because of their infinitesimally small size, nanoparticles may be more chemically reactive and therefore more bioavailable, and may behave differently than larger particles of the same substance; these characteristics may lead to potential damage in the human body or ecosystem.

The surge in demand for interior and exterior paints and use of plastic across various end-use industries drive the global Lithopone market. Lithopone white pigment is used in paints and coating systems that find applications in residential and industrial landscapes. Hence, as the construction & building sector flourishes, the demand for building and architectural materials such as paints and coatings will increase. This trend is conducive for the Lithopone market growth. In addition, white plastic materials are increasingly being used in consumer products. Developments in plastic forming technology is anticipated to indirectly boost plastic production, thus, increasing the demand for white pigments during the forecast period.

For a review published in 2023 in the journal Environmental Pollution, researchers examined E171 as a possible factor promoting obesity-related metabolic disorders. Because gut microbiota play an important role in immune function maintenance and development, and because titanium dioxide as a food additive has been shown to alter gut microbiota, researchers wanted to review “the dysregulations along the gut microbiota-immune system axis after oral TiO2 exposure compared to those reported in obese or diabetic patients, and to highlight potential mechanisms by which foodborne TiO2 nanoparticles may increase the susceptibility to develop obesity-related metabolic disorders.” The study authors discovered recurrent changes in the gut microbiota composition when exposed to titanium dioxide nanoparticles, with an imbalance of intestinal symbiotic microbiota. These changes and imbalances were also reported and played a role in the development of obesity, the authors wrote. This highlights “foodborne TiO2 nanoparticles as an endocrine disruptor-like chemical promoting obesity-related disorders,” the authors concluded.
