china about titanium dioxide

The use of lithopone in rubber products extends beyond mere coloration. Its unique chemical composition allows it to act as an effective UV stabilizer, protecting rubber from the degradative effects of sunlight exposure. Furthermore, lithopone contributes to enhancing the strength and durability of rubber compounds. Its fine particle size and uniform dispersion within the rubber matrix lead to improved stress distribution, thereby reducing the likelihood of cracks and fractures under mechanical strain.

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.
