In addition to its functional benefits, titanium dioxide also plays a crucial role in UV protection. It acts as a shield against harmful ultraviolet radiation, preventing premature degradation and maintaining the integrity of the rubber over time It acts as a shield against harmful ultraviolet radiation, preventing premature degradation and maintaining the integrity of the rubber over time It acts as a shield against harmful ultraviolet radiation, preventing premature degradation and maintaining the integrity of the rubber over time It acts as a shield against harmful ultraviolet radiation, preventing premature degradation and maintaining the integrity of the rubber over timetitanium dioxide for rubber supplier.

This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists’ pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.

  • The chloride process involves the chlorination of titanium ore to produce titanium tetrachloride, which is then oxidized to form titanium dioxide. This method produces high-purity TiO2 but requires the use of highly toxic chlorine gas and generates hazardous waste products.
  • The most significant uncertainty identified by the EU experts was the concern that TiO2 particles may have genotoxic effects. Genotoxicity refers to the ability of a chemical to directly damage genetic material within a cell (DNA), which may lead to cancer in certain situations. Although the experts did not conclude that TiO2 particles in E171 are genotoxic, they could not rule out the concern that they might be.
