- One of the key products offered by internal wall coating suppliers is damp-proof coatings. Damp can be a serious issue in buildings, leading to a range of problems such as mold growth and structural damage. Damp-proof coatings provide a barrier against moisture, preventing it from seeping into the walls and causing damage. These coatings are essential for maintaining the integrity of the building and ensuring the health and safety of its occupants.

Prof Matthew Wright, both a member of the FAF Panel and chair of EFSA’s working group on E 171, said: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”
The availability of other white pigments poses a major challenge for the Lithopone market during the forecast period. Other alternatives to Lithopone include Zinc White, Titanium Dioxide, Calcium Carbonate, Blanc Fixe, and Barytes. The use of TiO2 has reduced the commercial significance of the Lithopone in the pigments industry.
Titanium dioxide prices in the Asian market skyrocketed due to high demand and limited stock availability. Prices in the Chinese market surged significantly, reaching 2875 USD /MT at the end of March, well above the USD 2015/MT level in January 2021.

EU ban on titanium dioxide
Titanium dioxide (TiO2) is considered as an inert and safe material and has been used in many applications for decades. However, with the development of nanotechnologies TiO2 nanoparticles, with numerous novel and useful properties, are increasingly manufactured and used. Therefore increased human and environmental exposure can be expected, which has put TiO2 nanoparticles under toxicological scrutiny. Mechanistic toxicological studies show that TiO2 nanoparticles predominantly cause adverse effects via induction of oxidative stress resulting in cell damage, genotoxicity, inflammation, immune response etc. The extent and type of damage strongly depends on physical and chemical characteristics of TiO2 nanoparticles, which govern their bioavailability and reactivity. Based on the experimental evidence from animal inhalation studies TiO2 nanoparticles are classified as “possible carcinogenic to humans” by the International Agency for Research on Cancer and as occupational carcinogen by the National Institute for Occupational Safety and Health. The studies on dermal exposure to TiO2 nanoparticles, which is in humans substantial through the use of sunscreens, generally indicate negligible transdermal penetration; however data are needed on long-term exposure and potential adverse effects of photo-oxidation products. Although TiO2 is permitted as an additive (E171) in food and pharmaceutical products we do not have reliable data on its absorption, distribution, excretion and toxicity on oral exposure. TiO2 may also enter environment, and while it exerts low acute toxicity to aquatic organisms, upon long-term exposure it induces a range of sub-lethal effects.
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.

Does It Cause Cancer?
Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
Key Questions Answered in This Report:
Titanium dioxide, (TiO2), a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are rutile and anatase. These naturally occurring oxide forms can be mined and serve as a source for commercial titanium. Titanium dioxide is odourless and absorbent. Its most important function in powder form is as a widely used pigment for lending whiteness and opacity.
History
Plus, titanium dioxide is chemically inert, meaning it won't react with other substances in the paint. This stability ensures that the paint retains its original color and properties over time, preventing discolouration and degradation. Using titanium dioxide as an ingredient, the paint can withstand harsh weather conditions and prevent flaking, peeling or chalking. This exceptional durability makes it ideal for interior and exterior walls, ensuring a long-lasting and beautiful finish.
In some studies, E171 was given to animals in drinking water without the stabilizers that keep E171 suspended in the liquid. Without stabilizers, E171 can settle and prevent the ingredient from combining with surrounding ingredients.
Titanium dioxide R-5566, a rutile titanium dioxide pigment treated with zirconium and aluminum inorganic surface and organic surface, has the characteristics of high whiteness, high gloss, high achromatic power, high weather resistance, and good dispersibility.
Lithopone or sulphide of zinc white has been in general use for twenty years or more in many industries where a white pigment of considerable body or hiding power is required that is not subject to change like lead carbonate and has not the brittle character of zinc oxide, besides being sold at a lower figure than either of these. Nevertheless it is still comparatively new to the general painting trade. Because of our tariff protection its manufacture in this country has made great progress. Yet in spite of this and the duty imposed on it, the imports are still in excess of the quantity manufactured here. A short history of its origin will no doubt prove of interest to our readers.
Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified, and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.
Following the filtration, the precipitate is washed thoroughly to remove any impurities and excess reagents. This is a crucial step, as thorough washing ensures that no contaminants interfere with the final mass measurement. Once washed, the precipitate is dried in an oven at a controlled temperature to remove moisture, ensuring that the mass recorded reflects only the titanium content.
