titanium dioxide in plastics factories

It’s true that titanium dioxide does not rank as high for UVA protection as zinc oxide, it ends up being a small difference (think about it like being 10 years old versus 10 years and 3 months old). This is not easily understood in terms of other factors affecting how sunscreen actives perform (such as the base formula), so many, including some dermatologists, assume that zinc oxide is superior to titanium dioxide for UVA protection. When carefully formulated, titanium dioxide provides excellent UVA protection. Its UVA protection peak is lower than that of zinc oxide, but both continue to provide protection throughout the UVA range for the same amount of time.

The primary factor that affects the price of titanium dioxide is its production method. There are two main methods for producing titanium dioxide the chloride process and the sulfate process. The chloride process involves heating ilmenite ore in a furnace to produce titanium tetrachloride, which is then purified and reduced to titanium metal. This method produces high-quality titanium dioxide with a low impurity level, making it more expensive than the sulfate process.
