Additionally, they can be customized with different coatings, like zinc plating or anti-corrosion paint, to protect against rust and extend their service life.Analyst Insight
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.
The European region struggled with the rising inflation that caused energy prices to rise leading to higher production costs thereby, negatively impacting the prices of titanium dioxide. The transportation routes were further disrupted along with the uncertainties in the construction and automotive industries. In addition to this, the offtakes and purchasing behaviour of the end-user consumers also declined, fueling the declining price trendss for titanium dioxide.
Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.
The FDA is reviewing the safety of titanium dioxide in response to an April petition from EWG and other environmental and public health groups. This is the FDA’s first comprehensive review of titanium dioxide since 1973.
Amount: if too little titanium dioxide is added, the distance between particles is too large and there is not enough opacity, while if the titanium content is too high, the particles interfere with each other and poor efficiency is obtained.
Algaecidal effect of Lithopon: After 5 years of exposure to weathering in Alpen (Lower Rhine)

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.
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.
Last Friday, the domestic rutile and anatase titanium dioxide new single price was stable, and the overall transaction focus of the market moved up. Titanium dioxide factory work normally, part of the output of early orders, the spot supply has increased accordingly; And buyers still have inventory digestion, the current mentality turned to wait-and-see. The volume of new orders in the market is limited.The key factors affecting the current market price change1.
