One of the primary categories of chemicals used in wastewater treatment is coagulants. Coagulants, such as aluminum sulfate (alum) and ferric chloride, are essential for the aggregation of suspended particles in water. When added to wastewater, these chemicals neutralize the electrical charges on particles, allowing them to clump together and form larger aggregates known as flocs. This process, known as coagulation, significantly enhances the efficiency of sedimentation and filtration processes in both primary and secondary treatment stages.
The Chemical Abstracts Service (CAS) registry number is a unique identifier for chemical substances. CAS 204584-46-7 corresponds to a compound known as Tofacitinib, which is particularly known for its role as a Janus kinase (JAK) inhibitor. This compound is pivotal in the treatment of several autoimmune disorders, including rheumatoid arthritis, ulcerative colitis, and psoriasis.
The sustainability and environmental impact of API production are also becoming focal points in the conversation around importing these substances. As consumers and regulators alike push for greener practices, pharmaceutical companies face pressure to consider the environmental implications of their supply chains. This may involve selecting suppliers based on their adherence to environmentally friendly manufacturing processes or investing in technologies that reduce waste and emissions during production.
Bone healing is a complex biological process that involves the regeneration and remodeling of bone tissue following injury or fracture. While proper medical treatment and rehabilitation are essential for optimal recovery, certain dietary supplements can play a significant role in enhancing bone healing. This article explores the primary supplements that can aid in bone health and recovery.

FAQ – EFSA 2021 safety assessment of titanium dioxide (E171)
In January 2022, the average price of domestic titanium dioxide in local Chinese marketplaces was 20,735 RMB/MT. Traders were more careful in purchasing goods and downstream industries purchased things on demand. As a result, the overall market demand for titanium dioxide was general.
In their role as risk managers, the European Commission and Member States will now reflect on EFSA’s scientific advice and decide upon any appropriate regulatory measures or advice for consumers.

The properties of lithopone are very suitable for use in the production of coatings. Because the ingredients of lithopone are zinc sulfide and barium sulfate, and the more zinc sulfide content, the stronger its covering power. This indicates a paint product with strong white covering power. It is different from water in that it reacts with acid but does not react with alkali. It has a wide range of uses. Because its structural properties are similar to titanium dioxide and its price is relatively cheap, it can also be used as a substitute for some titanium dioxide. Lithopone can be used for coloring paints, inks, pigments, rubber, paper, leather, enamel, etc.
As for titanium dioxide, the FDA approved titanium dioxide for use as a food additive in 1966. The last time the agency reviewed the additive’s safety, according to the Guardian, was in 1973.

It's also used in sunscreens as a UV filtering ingredient, helping to protect a person's skin by blocking absorption the ultraviolet light that can cause sunburn and cancer.
Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.
Magnesium occurs in seawater and in ores such as dolomite (CaCO 3 MgCO 3), magnesite (MgCO 3), and carnallite (MgCl 2 KCl 6H 2O).
Titanium dioxide nanoparticles are commonly found in a wide-range of consumer goods, including cosmetics, sunscreens, paints and colorings, ceramics, glass, textiles, construction materials, medicine, food, food packaging, and more. In Europe, cosmetic companies are required to label products that contain nanoparticles. In the U.S., companies are not.


Variations of titanium dioxide are added to enhance the whiteness of paint, plastics, and paper products, though these variations differ from the food-grade ones for things we eat (1Trusted Source, 2Trusted Source).
In 2022, a year after the EFSA recommended against the use of E171, the Food Standards Australia New Zealand (FSANZ) conducted its own reassessment of titanium dioxide as a food additive. The agency concluded that titanium dioxide was indeed safe to use as a food additive. The United Kingdom and Canada came to similar conclusions.
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.
Additionally, the committee noted that the available data did not provide convincing evidence of genotoxicity for titanium dioxide as a food additive, but recognized the limitations in current methodologies with respect to the testing of poorly soluble particulate materials. Although there were uncertainties in the genotoxicity data, the experts took into account the fact that the additive was not carcinogenic in adequately conducted two-year studies in mice and rats at doses of up to 7,500 mg/kg BW per day for mice, and 2,500 mg/kg BW per day for rats, the highest doses tested. There was also no evidence of reproductive or developmental toxicity in studies in rats at doses up to 1,000 mg/kg BW per day, the highest doses tested.
