In terms of refractive index and opacity, lithopone surpasses zinc oxide and lead oxide. Lithopone's high refractive index allows it to efficiently scatter and reflect light, thereby increasing the opacity of various media. Whether you need to enhance the opacity of paints, inks or plastics, lithopones deliver outstanding results, ensuring your final product is completely opaque.

Data availability statement
A review published in 2022 in the journal NanoImpact evaluated the latest research related to genotoxic effects of titanium dioxide through in vivo studies and in vitro cell tests. Researchers summarized the results by stating TiO2 nanoparticles “could induce genotoxicity prior to cytotoxicity,” and “are likely to be genotoxic to humans.”
JECFA also evaluated estimates of dietary exposure to titanium dioxide, estimating the maximum 95th percentile of exposure to be 10 mg/kg BW per day. Overall, considering the low oral absorption of titanium dioxide as a food additive, the committee reaffirmed the ADI “not specified” that was established at the 13th meeting.
This work confirms previous studies that show P-25 and other untreated anatase 377 nanoparticles should not be employed in sunscreens because the toxicity of P25TiO2NPs under UV radiation is significant.
Water solubles, %
We’re most often exposed to E171 through the foods we ingest. We find E171 in many food products, like popsicles, ice cream, gum, and more. Another way we ingest E171 is through pharmaceutical drugs. Many pills and capsules contain E171 as an inactive ingredient.
Biointerfaces, Biomimicking, and Biohybrid Systems
EFSA has updated its safety assessment of the food additive titanium dioxide (E 171), following a request by the European Commission in March 2020.
Earlier this year, a bill was introduced in the California legislature to ban the manufacture, sale and distribution of foods in the state containing titanium dioxide, along with four other harmful food chemicals.
