Sulphate and chloride methods
- One of the primary uses of titanium dioxide is in the production of paints and coatings. It is used as a pigment to provide a pure white color and enhance the opacity of the paint. The chemical inertness of titanium dioxide makes it resistant to weathering and fading, ensuring that painted surfaces maintain their appearance for extended periods.
On November 23, 2022, the General Court of the European Union reversed the conclusion that titanium dioxide was carcinogenic and released a statement (1,2):
“First, the Commission made a manifest error in its assessment of the reliability and acceptability of the study on which the classification was based and, second, it infringed the criterion according to which that classification can relate only to a substance that has the intrinsic property to cause cancer.”
As part of our mission at CRIS we base our safety assessments on the currently available scientific evidence and consider many variables (e.g., study quality, journal of publication, etc.), even if it goes against previous conclusions. Evidence-informed decisions making is critical to ensure that the laws and regulations put into place are for the benefit of the population.
The EU General Court maintains that the scientific evidence presented wasn’t the complete picture for the ingredient, “in the present case, the requirement to base the classification of a carcinogenic substance on reliable and acceptable studies was not satisfied.”
In conclusion, the MBR9668 rutile titanium dioxide coating is a revolutionary product that enhances the quality, efficiency, and sustainability of coatings across various industries. As a leading supplier of this material, companies can provide clients with high-performance solutions that meet modern demands for durability and aesthetics. With its unique benefits and applications, MBR9668 stands out as a key component in the future of quality coatings, setting new standards in product performance and longevity.
Packaging containing this additive has been shown to decrease ethylene production in fruit, thus delaying the ripening process and prolonging shelf life (4Trusted Source).
In addition to hiding power, titanium dioxide also plays a vital role in enhancing the durability of paints. It acts as a barrier, protecting the walls from external elements such as UV radiation, moisture and pollutants. Titanium dioxide's high refractive index allows it to reflect harmful UV rays, preventing them from fading paint and retaining its vibrant colors for a long time. This UV resistance is especially important for facades that are exposed to sunlight throughout the day.

In its 2016 opinion, the ANS Panel recommended new studies be carried out to fill the gaps on possible effects on the reproductive system, which could enable them to set an Acceptable Daily Intake (ADI ). Uncertainty around the characterisation of the material used as the food additive (E 171) was also highlighted, in particular with respect to particle size and particle size distribution of titanium dioxide used as E 171.

What Is Titanium Dioxide?
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.

What's the Verdict?
The realization of neuromorphic resistive memory in TiO2 thin films (Strukov et al., 2008) marked an important milestone in the search for bio-inspired technologies (Chua and Kang, 1976). Many research proposals urged a focus on memristivity as the common feature of two electrical models: (i) electromigration of point defects in titanium oxide systems (Baiatu et al., 1990; Jameson et al., 2007) and (ii) voltage-gated ionic channels in the membranes of biological neurons (Hodgkin and Huxley, 1952). In this regard, memristors functionally mimic the synaptic plasticity of biological neurons, and thus can be implemented in artificial and hybrid neural networks. This includes a new paradigm of future computing systems (Zidan, 2018) and biocompatible electronics such as biointerfaces and biohybrid systems (Chiolerio et al., 2017).
What Is Titanium Dioxide?
Titanium dioxide, also called titania, is an odorless white powder and naturally occurring mineral that is widely used as a pigment for its brightness and whitening effects on a variety of materials, such as paint, plastic, paper, cosmetics, sunscreens, toothpastes and foods.
It’s produced through the sulfate or chloride process, which both involve treating titanium ore with sulfuric or hydrochloric acid to produce titanium sulfate or titanium chloride. These materials are then further processed to remove impurities and produce titanium dioxide in its final form.
Food-grade titanium dioxide differs from what’s added to plastics and paints to enhance whiteness. However, there have been concerns about the environmental impact of titanium dioxide production and the potential health risks from exposure to its particles.
Although food-grade titanium dioxide must be 99 percent pure, there’s still a risk of it containing potential contaminants, such as mercury, lead and arsenic. Additionally, inhaling the mineral over time can possibly cause it to build up in your body, leading to adverse effects.
