titanium dioxide baso4 factories

The determination of sulfate in various matrices is a critical task for environmental monitoring, industrial process control, and quality assurance in chemical production. When present in high concentrations, sulfates can pose health risks and impact the ecosystem. However, the analytical challenge often lies not just in detecting the presence of sulfates but also in accurately quantifying them, especially when they are to be determined as titanium dioxide (TiO2). This article delves into the methodologies used to determine sulfate as TiO2, highlighting the complexities and nuances involved in such an analysis.

On the other hand, the U.S. Food and Drug Administration (FDA) in their Final Administrative Order on Sunscreen Drug Products posted in September 2021 still accepts titanium dioxide up to 25% in the list of Generally Recognized As Safe and Effective (GRASE) in the main document, without further clarification on what kind or size of particles [9]. However, on page 24 (Sunscreen containing nanomaterials) FDA clearly “distinguish nanomaterials from other forms of these ingredients'' (zinc oxide and titanium dioxide) and ask for comments on “any particular nanomaterials that you believe should not be permitted for use in OTC sunscreen products”. To the best of our knowledge, this Agency did not ban the use of nanoparticulate titanium dioxide in any form, even though it is mentioned on page 34 that the anatase form is the more photoactive one, due to the lack of evidence with real sunscreens OTC (over the counter) in vivo. Moreover, other regulations in Latin America (MERCOSUR agreement, 2006) do not state clearly their position on the use of nanoparticulate TiO2NPs [10].

One notable aspect of TiO2 factories is their commitment to sustainable practices. Given the potential environmental impact of titanium dioxide production, these factories often incorporate advanced technologies to minimize waste and reduce emissions. For instance, the chloride process and sulfate process, two primary methods used in TiO2 manufacturing, are continuously being refined for higher efficiency and lower environmental footprint.

In a 2016 study published in Scientifica (Cairo), Egyptian researchers examined the effects of titanium dioxide nanoparticles on the organs of mice by orally administering the food additive daily, for five days. The results showed that the exposure produced “mild to moderate changes in the cytoarchitecture of brain tissue in a time dependent manner.” Furthermore, “Comet assay revealed the apoptotic DNA fragmentation, while PCR-SSCP pattern and direct sequencing showed point mutation of Presenilin 1 gene at exon 5, gene linked to inherited forms of Alzheimer’s disease.” The researchers wrote: “From these findings, “the present study concluded that TiO2NPs is genotoxic and mutagenic to brain tissue which in turn might lead to Alzheimer’s disease incidence.”
