Other experts say there is simply no conclusive evidence at this point that titanium dioxide is damaging to humans after ingesting. Kaminski in particular said the research studies cite health hazards that were found by using high doses of the product, which you would not normally see in food.

Here's what you need to know about titanium dioxide:

Titanium dioxide has also been classified as a possible human carcinogen by the International Agency for Research on Cancer, which has caused concern about its use in food products. This classification, however, is currently based on limited evidence from animal studies that involved the inhalation of titanium dioxide particles that increased the risk of lung cancer.

Lomon, one of the leading titanium dioxide manufacturers in China, produces the R996 grade titanium dioxide with purity levels exceeding 99%. This high purity ensures that the pigment provides excellent hiding power and color retention in paints, making it a popular choice for the paint industry.

EU ban on titanium dioxide

Still many experts say the body of research does not support the current health concerns being expressed about titanium dioxide.

Uses of Titanium Dioxide

When manufacturers add titanium dioxide to foods and other ingestible products, it’s typically referred to as E171, which relates to food-grade purity.

The whole scientific experimental design in some of these studies is‌ very flawed, Kaminski said.

European food safety regulators have since labeled titanium dioxide as no longer safe for human consumption, due to its potential toxicity.
