Risk managers at the European Commission and in EU Member States have been informed of EFSA’s conclusions and will consider appropriate action to take to ensure consumers’ protection.
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.
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.
The assessment was conducted following a rigorous methodology and taking into consideration many thousands of studies that have become available since EFSA’s previous assessment in 2016, including new scientific evidence and data on nanoparticles.
The production of titanium dioxide powder has significant environmental impacts, primarily due to the energy-intensive nature of the chloride process
cas: 13463-67-7 titanium dioxide powder factory. However, manufacturers are increasingly adopting more sustainable practices to minimize their environmental footprint. For instance, they are exploring alternative production methods such as the sulfate process, which uses sulfuric acid instead of chlorine gas, resulting in lower greenhouse gas emissions.
The versatility of rutile type TiO2 extends to the field of cosmetics, where its non-toxic nature and ability to reflect UV light make it an ideal sunscreen ingredient. It is also utilized in food coloring due to its safety and efficacy in providing bright, appealing hues to food products.
In conclusion, calcium carbonate and titanium dioxide are important minerals that are used in various industries. While they are both produced by manufacturers, they have different manufacturing processes and applications. Understanding the differences between these two minerals can help industries make informed decisions about which one to use for their specific needs.
