- When it comes to cost-effectiveness, titanium dioxide is a relatively inexpensive raw material. Its low price point makes it an attractive option for manufacturers looking to reduce costs without sacrificing quality. However, the price of titanium dioxide can vary depending on factors such as purity, particle size, and production methods.
- In the cosmetics industry, titanium dioxide is used as a sunscreen agent due to its ability to block harmful UV rays
wholesale define titanium dioxide. It is also used in makeup products to create a natural, matte finish. In the food industry, titanium dioxide is used as a colorant to enhance the appearance of foods and beverages.
- One of the primary factors supporting the growth of the wholesale titanium dioxide market is its versatility. Used in a wide variety of applications, such as paints, plastics, coatings, and paper products, demand for titanium dioxide remains robust across various sectors. The increasing demand for architectural and industrial paints, coupled with the ongoing innovations in the plastic industry, have bolstered demand for this versatile white pigment.
Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:
The author thanks Marco Leona, Scientist-in-Charge of the Department of Scientific Research at the Metropolitan Museum of Art for conducting fluorescence spectrometry on Wheel of Fortune and a valuable discussion of the research, as well as Silvia Centeno, Research Scientist at the Metropolitan Museum of Art, who performed Raman analysis on the watercolors and also contributed her insight. The phenomenon of the phosphorescing lithopone was originally discovered during the author's fellowship in the Sherman Fairchild Center for the Conservation of Works on Paper, funded by the Andrew W. Mellon Foundation. The author thanks all her colleagues for their ideas and support during the research of this paper, and special thanks to Rachel Mustalish for her assistance in editing this work.
The EU expert panel did not identify an immediate health concern linked to TiO2 when used as a food additive. However, due mainly to uncertainties concerning the safety of TiO2 nanoparticles, the panel concluded that TiO2 as a food additive (E171) could no longer be considered safe.
On the other hand, Westerhoff said, there are hundreds of studies showing no adverse effects from the substance.
