- Another important consideration in the production of titanium dioxide is environmental sustainability. The industry has made significant progress in reducing its environmental impact by adopting more efficient processes and technologies. For example, many factories now use closed-loop systems that recycle water and other resources, minimizing waste and emissions.
- Titanium dioxide is a versatile and widely used compound that finds applications in various industries, including paints, plastics, paper, inks, food colorants, and sunscreens. The preparation of titanium dioxide from suppliers involves a series of carefully controlled processes to ensure the purity and consistency required for these diverse applications.
Zinc Oxide
Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.

Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.”



If you want to avoid titanium dioxide, read labels carefully and stick to minimally processed whole foods.
Lithopone B301, Lithopone B311 powder is widely used in coatings, printing ink, rubber, plastic industry, etc.


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.
In addition to the toxic effects of TiO2 NPs, discussed in previous chapters, these NPs have been also shown to promote photosynthesis and nitrogen metabolism, resulting in the enhanced growth of spinach. It increases the absorption of light and accelerates the transfer and transformation of the light energy. It was also found that treatment with nano-sized TiO2 significantly increased the level of antioxidant enzymes, and decreased the ROS accumulation and malonyldialdehyde content in spinach chloroplasts under visible and UV irradiation. TiO2 NPs also increased the superoxide dismutase activity of germinating soybean, enhanced its antioxidant ability, and promoted seed germination and seedling growth.
You may be taking a second look at your favorite candy after hearing this week's news about titanium dioxide. Recently, a lawsuit was filed against Mars, Inc. based on claims that the manufacturer's popular Skittles candy is unfit for human consumption. The class-action lawsuit, filed in U.S. District Court for the Northern District of California in mid-July, alleged that the candy contained heightened levels of a known toxin called titanium dioxide — a food additive that the company previously pledged to phase out from their products in 2016, according to the Center for Food Safety.
Another challenge facing TiO2 industry suppliers is the increasing environmental regulations and sustainability requirements. The production of TiO2 can have environmental impacts, such as energy consumption and waste generation. Suppliers must invest in sustainable practices and technologies to minimize their environmental footprint and meet regulatory requirements.
