- Kiểm tra và bảo trì định kỳ Sau khi thay lốp, hãy kiểm tra áp suất và độ bám của lốp thường xuyên để đảm bảo an toàn.
But before titanium dioxide is made into sunscreens, it is first micronized. This is a process that takes ingredients that are normally quite heavy (like titanium dioxide) and makes them both stabler and easier to spread. And when micronized, titanium dioxide doesn’t penetrate the skin. That means that you’re getting all the sun protection benefits without the risk of harming yourself.
All in all, Titanium Dioxide is a famous sunscreen agent and for good reason, it gives broad spectrum UV protection (best at UVB and UVA II), it's highly stable, and it has a good safety profile. It's definitely one of the best UV-filter agents we have today, especially in the US where new-generation Tinosorb filters are not (yet) approved.

Studies of titanium dioxide as a food additive suggest health dangers
- China's titanium oxide industry has also been investing in research and development to improve the quality and performance of their products. By developing new processing techniques and formulations, Chinese manufacturers are able to offer a wide range of titanium oxide products that meet the diverse needs of their customers
china titanium oxide. This has helped China to establish a strong presence in the global titanium oxide market, competing with other major producers such as the United States, Germany, and Japan. Since then, there has been a few animal studies suggesting titanium dioxide is connected to cancer. A 2017 study in Scientific Reports, for instance, found that rats with titanium dioxide in their diet had impaired immune systems, which could contribute to autoimmune diseases and colorectal cancer.
The concern from animal studies is that high amounts of titanium dioxide have increased inflammation and colon tumor formation, said Dr. Johnson-Arbor. A 2021 review, meanwhile, suggested that using titanium dioxide as a food additive weakens the gut lining and worsens the progression of inflammatory bowel disease.
