Titanium Dioxide is largely produced by the reduction of titanium tetrachloride, obtained in turn from chlorination of natural rutile, synthetic rutile derived from ilmenite or even slags rich in TiO2 produced by metallurgical treatment of ilmenite. TiO2 is also manufactured by treatment of ilmenite with sulfuric acid. Raw materials and the respective production processes employed in the manufacturing of Titanium Dioxide are listed below.
Although cosmetics are not meant for consumption, there are concerns that titanium dioxide in lipstick and toothpaste may be swallowed or absorbed through the skin.

Resumo–Este artigo discute a descoberta de litopônio fosforescente em desenhos de aquarela do artista americano John La Farge datados de entre 1890 e 1905 e a história do litopônio na indústria de pigmento no final do século XIX e início do século XX. Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.
In a 2022 study published in the Journal of Hazardous Materials, scientists wanted to examine the effects of titanium dioxide as a food additive on atherosclerosis in mice. (Atherosclerosis refers to a hardening of the arteries.) Researchers fed mice 40 mg/kg of the food additive every day for 4 months, and found that it not only altered gut microbiota but also led to a significantly increased atherosclerotic lesion area, especially in animals that consumed a high-choline western diet (HCD).

Our recommendation is to use both a flat and a fitted sheet, with a coverlet and/or duvet to be used on top of the flat sheet. For the more travelled customer, who loves all things European, will sleep without a flat sheet, with the duvet directly hovering over them. The caveat here is that it is easier to wash a flat sheet than it is to remove, wash and put a duvet cover back on.
A bedspread is a thin, decorative covering that normally covers the entire bed and touches the floor. Cotton, chenille, wool, or polyester are common bedspread materials.
